The Lightblade Learning Lab with Russ Sadler
The Lightblade Learning Lab is a series of videos that Russ did for Thinklaser Limited based on using the Lightblade 4060 Laser Cutting and Laser Engraving Machine. Thinklasers Lightblade 4060 has a 400 x 600mm bed size and was supplied with a 60W EFR laser tube. In this video, Russ discusses the process of laser job positioning and goes on to explain how Virtual Arrays work.

2
00:00:15.25 –> 00:00:20.740
welcome to another lightblade learning lab
3
00:00:17.92 –> 00:00:22.869
today we’re going to cover a couple
4
00:00:20.74 –> 00:00:26.619
of topics that crop up regularly as
5
00:00:22.869 –> 00:00:30.279
questions one of them is how do I locate
6
00:00:26.619 –> 00:00:33.640
my work so that it’s always referenced
7
00:00:30.279 –> 00:00:37.750
to the same position and the second
8
00:00:33.64 –> 00:00:39.760
question is all about arrays there are
9
00:00:37.75 –> 00:00:42.010
two types of array in RDWorks what
10
00:00:39.76 –> 00:00:44.950
happens called array and the other ones
11
00:00:42.01 –> 00:00:47.500
called virtual array there is a big
12
00:00:44.95 –> 00:00:49.660
difference between the two that many
13
00:00:47.5 –> 00:00:51.220
people don’t actually understand so
14
00:00:49.66 –> 00:00:53.860
we’ll check on that subject later on
15
00:00:51.22 –> 00:00:57.580
after we’ve touched on how do I locate
16
00:00:53.86 –> 00:00:59.020
my work to a reference point now the
17
00:00:57.58 –> 00:01:03.250
most important part of that last
18
00:00:59.02 –> 00:01:06.189
sentence was reference point the word
19
00:01:03.25 –> 00:01:10.600
reference basically means somewhere that
20
00:01:06.189 –> 00:01:14.310
I can rely on that’s fixed so when we
21
00:01:10.6 –> 00:01:14.310
start the Machine off and we do a reset
22
00:01:15.63 –> 00:01:21.430
the Machine goes to its own reference
23
00:01:18.579 –> 00:01:24.100
point and it sets a zero zero in that
24
00:01:21.43 –> 00:01:26.440
corner and if I drive the machine to
25
00:01:24.1 –> 00:01:29.500
there and look on the keyboard it will
26
00:01:26.44 –> 00:01:32.979
say 0 for X and 0 for Y now I’m just
27
00:01:29.5 –> 00:01:34.720
going to remove my steel solid table to
28
00:01:32.979 –> 00:01:38.350
reveal what’s underneath which is a
29
00:01:34.72 –> 00:01:40.810
fixed slap table the one thing about a
30
00:01:38.35 –> 00:01:44.340
reference point is it cannot wander
31
00:01:40.81 –> 00:01:48.850
around so if you grab hold of your table
32
00:01:44.34 –> 00:01:50.680
and it moves you can’t have a reference
33
00:01:48.85 –> 00:01:52.900
point as the machine moves around and
34
00:01:50.68 –> 00:01:55.270
shakes your table could equally well
35
00:01:52.9 –> 00:01:58.150
move in the opposite direction possibly
36
00:01:55.27 –> 00:02:00.970
and give the errors so it’s absolutely

37
00:01:58.15 –> 00:02:04.799
fundamental that the table is solid you
38
00:02:00.97 –> 00:02:04.799
will have also be supplied
39
00:02:05.479 –> 00:02:11.739
with one of these a honeycomb table I
40
00:02:13.15 –> 00:02:18.110
don’t think you could call that a
41
00:02:15.23 –> 00:02:21.739
reference to you now I’ve attempted to
42
00:02:18.11 –> 00:02:23.750
make this into a reference table because
43
00:02:21.739 –> 00:02:28.010
what I’ve done on each of the corners I
44
00:02:23.75 –> 00:02:31.430
have removed the screws and I’ve put a
45
00:02:28.01 –> 00:02:33.709
small stainless steel angle on each
46
00:02:31.43 –> 00:02:36.620
corner on opposite corners now this
47
00:02:33.709 –> 00:02:40.519
gives me the opportunity of juggling the
48
00:02:36.62 –> 00:02:44.510
corners over the solid part of the
49
00:02:40.519 –> 00:02:47.600
bedroom it is possible to move this and
50
00:02:44.51 –> 00:02:49.310
trap it underneath these points here so
51
00:02:47.6 –> 00:02:51.680
that’s the main reason why I put corners
52
00:02:49.31 –> 00:02:54.019
on the honeycomb bed now because I never
53
00:02:51.68 –> 00:02:56.330
use this as a reference and I rarely use
54
00:02:54.019 –> 00:02:59.780
this as a table as you can see after
55
00:02:56.33 –> 00:03:03.230
nearly two years this table is almost
56
00:02:59.78 –> 00:03:04.970
clean because I don’t use it a very
57
00:03:03.23 –> 00:03:07.400
personal opinion this is one of the
58
00:03:04.97 –> 00:03:09.709
worst things that was ever put onto a
59
00:03:07.4 –> 00:03:12.560
laser machine if you love this sort of
60
00:03:09.709 –> 00:03:15.019
table then go ahead and use it but what
61
00:03:12.56 –> 00:03:17.120
I would advise you to do is this now
62
00:03:15.019 –> 00:03:19.340
we’ve got the corners on but because
63
00:03:17.12 –> 00:03:21.440
we’ve still got movement there all right
64
00:03:19.34 –> 00:03:23.480
now we can get rid of that movement with
65
00:03:21.44 –> 00:03:27.260
a little bit of brutality we can grab
66
00:03:23.48 –> 00:03:34.069
hold of these corners and we can bend
67
00:03:27.26 –> 00:03:37.069
them in very slightly here and here
68
00:03:34.069 –> 00:03:41.170
so with a little bit of judicious
69
00:03:37.069 –> 00:03:46.189
bending of those corners I can make this
70
00:03:41.17 –> 00:03:48.680
now into a basically part solid part of
71
00:03:46.189 –> 00:03:51.560
the table underneath so that there’s no
72
00:03:48.68 –> 00:03:53.900
movement on it now although this corner
73
00:03:51.56 –> 00:03:57.019
here is not zero zero as you can see
74
00:03:53.9 –> 00:03:59.120
it’s probably something like 50/50 in
Transcript for Laser Job Positioning and Virtual Arrays (Cont…)
75
00:03:57.019 –> 00:04:02.000
other words we’ve lost 50 millimetres of
76
00:03:59.12 –> 00:04:05.480
available work space if I use that
77
00:04:02.0 –> 00:04:07.700
corner there as a reference I couldn’t
78
00:04:05.48 –> 00:04:10.040
decide to locate my work there now I
79
00:04:07.7 –> 00:04:13.280
can’t guarantee that this edge here and
80
00:04:10.04 –> 00:04:15.169
this edge here are absolutely true and
81
00:04:13.28 –> 00:04:16.970
square to the axis of the machine in
82
00:04:15.169 –> 00:04:19.160
fact I can see when I look down the edge
83
00:04:16.97 –> 00:04:21.859
here that this table is very slightly
84
00:04:19.16 –> 00:04:29.050
probably out of position use some
85
00:04:21.859 –> 00:04:29.050
double-sided tape on here
86
00:04:31.139 –> 00:04:35.710
okay now I’ve got a piece of scrap
87
00:04:33.28 –> 00:04:37.960
acrylic here which I’m going to peel the
88
00:04:35.71 –> 00:04:42.819
covering off on I’m using acrylic
89
00:04:37.96 –> 00:04:44.620
because it’s a nice shiny surface and
90
00:04:42.819 –> 00:04:47.870
the double-sided tape that I’ve put on
91
00:04:44.62 –> 00:04:50.590
here will stick well to it
92
00:04:47.87 –> 00:04:54.810
speed to about
93
00:04:50.59 –> 00:04:54.810
five or four of three
94
00:04:55.89 –> 00:04:59.550
and I should be able to get those
95
00:04:57.3 –> 00:05:02.800
dimensions fairly now
96
00:04:59.55 –> 00:05:05.729
29.9 a little prick
97
00:05:02.8 –> 00:05:05.729
30 get
98
00:05:06.84 –> 00:05:14.730
and this one here in X is 30 as well so
99
00:05:12.33 –> 00:05:17.850
I’ve got my zero in that corner sector
100
00:05:14.73 –> 00:05:20.000
30 30 so if I press the origin button
101
00:05:17.85 –> 00:05:20.000
now
102
00:05:20.38 –> 00:05:27.460
and I’ll set my power pole power and my
103
00:05:24.97 –> 00:05:29.330
speed a suitable speed to cut this
104
00:05:27.46 –> 00:05:31.340
material
105
00:05:29.33 –> 00:05:34.759
and that will be around about probably
106
00:05:31.34 –> 00:05:36.919
eight millilitres a second and just make
107
00:05:34.759 –> 00:05:38.760
sure we’ve got the focus height set
108
00:05:36.919 –> 00:05:41.829
knife
109
00:05:38.76 –> 00:05:41.829
[Music]
110
00:05:41.88 –> 00:05:48.629
hold the post button down
111
00:05:45.069 –> 00:05:48.629
and press the left arrow
112
00:05:52.37 –> 00:05:57.340
okay
113
00:05:53.86 –> 00:06:00.190
now remember I set the origin at 1330
Transcript for Laser Job Positioning and Virtual Arrays (Cont…)
114
00:05:57.34 –> 00:06:04.020
it’s going to take me ages to send that
115
00:06:00.19 –> 00:06:06.240
head back to zero so if I press reset
116
00:06:04.02 –> 00:06:08.970
what happened is it will go back at a
117
00:06:06.24 –> 00:06:12.800
comfortable speed and it will set back
118
00:06:08.97 –> 00:06:12.800
to 30 30 in the origin point
119
00:06:15.15 –> 00:06:20.460
there we go keyboard says 30 40 so now I
120
00:06:18.78 –> 00:06:20.820
can do exactly the same thing in the
121
00:06:20.46 –> 00:06:24.080
wires
122
00:06:20.82 –> 00:06:24.080
it’s hold the pulse button on
123
00:06:30.279 –> 00:06:37.279
we’ve never got an absolutely perfectly
124
00:06:33.229 –> 00:06:40.759
square reference each to work to to put
125
00:06:37.279 –> 00:06:44.150
our work in and the table is not moving
126
00:06:40.759 –> 00:06:46.309
so we can guarantee that position 30 30
127
00:06:44.15 –> 00:06:49.069
is always going to be in that corner
128
00:06:46.309 –> 00:06:51.080
there now
129
00:06:49.069 –> 00:06:54.080
I must remind you that every time you
130
00:06:51.08 –> 00:06:56.240
take this table off it may not go back
131
00:06:54.08 –> 00:06:58.879
in the same position we’ll carry on
132
00:06:56.24 –> 00:07:01.339
using this table for the moment as we
133
00:06:58.879 –> 00:07:04.099
have already set their reference up and
134
00:07:01.339 –> 00:07:08.419
we go and take a look how we should use
135
00:07:04.099 –> 00:07:11.599
this for working with in our D works now
136
00:07:08.419 –> 00:07:15.110
at the moment any job that I put on to
137
00:07:11.599 –> 00:07:19.009
this drawing has got the head position
138
00:07:15.11 –> 00:07:23.120
shown with a little green square now
139
00:07:19.009 –> 00:07:25.849
that head position is defined by coming
140
00:07:23.12 –> 00:07:28.029
down here and we will find that what
141
00:07:25.849 –> 00:07:31.729
we’ve got is something called position
142
00:07:28.029 –> 00:07:34.520
current position and current position
143
00:07:31.729 –> 00:07:38.419
means that wherever you position the
144
00:07:34.52 –> 00:07:41.389
head and press the origin button that is
145
00:07:38.419 –> 00:07:43.339
where the head will start we can come
146
00:07:41.389 –> 00:07:46.639
down to here and we can change this
147
00:07:43.339 –> 00:07:50.149
current position to absolute co-ordinate
148
00:07:46.639 –> 00:07:54.289
and that’s what I would recommend that
149
00:07:50.149 –> 00:07:58.219
you do because now what I’ve done I’ve
Transcript for Laser Job Positioning and Virtual Arrays (Cont…)
150
00:07:54.289 –> 00:08:01.339
changed this so that when the machine
151
00:07:58.219 –> 00:08:04.849
cuts this job it will cut it from the
152
00:08:01.339 –> 00:08:06.199
co-ordinate of this head position now
153
00:08:04.849 –> 00:08:11.899
this starts to get a little bit more
154
00:08:06.199 –> 00:08:15.580
complicated because at the moment the
155
00:08:11.899 –> 00:08:19.550
reference position for this object is
156
00:08:15.58 –> 00:08:23.360
relative to the centre point there and
157
00:08:19.55 –> 00:08:28.729
let me just explain to you if we go to
158
00:08:23.36 –> 00:08:30.649
config system setting we should find
159
00:08:28.729 –> 00:08:33.560
that we’ve got the position for the
160
00:08:30.649 –> 00:08:36.289
laser head shown which is the Green
161
00:08:33.56 –> 00:08:39.050
Square and those nine positions for the
162
00:08:36.289 –> 00:08:42.440
head should not be confused with this
163
00:08:39.05 –> 00:08:45.260
little box up here beside the padlock
164
00:08:42.44 –> 00:08:48.230
on that and you’d find another nine
165
00:08:45.26 –> 00:08:50.120
positions at the moment you’ll see that
166
00:08:48.23 –> 00:08:52.700
the dot is right in the middle
167
00:08:50.12 –> 00:08:54.770
now just for convenience I’m going to do
168
00:08:52.7 –> 00:08:56.750
two things first of all I’m going to
169
00:08:54.77 –> 00:08:58.430
mark that square and we’re going to
170
00:08:56.75 –> 00:09:05.480
change its position we’re going to
171
00:08:58.43 –> 00:09:08.330
change its dimensions to 100 by 100 and
172
00:09:05.48 –> 00:09:13.160
now I’m going to drive it to position
173
00:09:08.33 –> 00:09:18.200
and here we got X&Y at the top here to
174
00:09:13.16 –> 00:09:20.600
position 1 hunt position 50/50 and you
175
00:09:18.2 –> 00:09:28.880
see where it’s driven to now it’s driven
176
00:09:20.6 –> 00:09:31.360
to the centre point here at 50/50 now if
177
00:09:28.88 –> 00:09:31.360
I change
178
00:09:33.39 –> 00:09:41.370
this here to that position if I now
179
00:09:39.0 –> 00:09:44.160
check the co-ordinate position of that
180
00:09:41.37 –> 00:09:45.800
square you’ll see that it now says zero
181
00:09:44.16 –> 00:09:50.010
zero
182
00:09:45.8 –> 00:09:52.050
that’s because look I’ve set this corner
183
00:09:50.01 –> 00:09:57.000
position here which is the position
184
00:09:52.05 –> 00:10:02.399
reference for the object to zero zero so

185
00:09:57.0 –> 00:10:05.760
even if I draw a circle now and I make
186
00:10:02.399 –> 00:10:09.420
that circle let’s just close the padlock
187
00:10:05.76 –> 00:10:11.880
and I make that circle 100 millimeters I
188
00:10:09.42 –> 00:10:15.149
put handles around that I’ve still got
189
00:10:11.88 –> 00:10:22.700
this Center position shown but if I tell
190
00:10:15.149 –> 00:10:22.700
that Square to go to positioned zero
191
00:10:23.66 –> 00:10:33.120
zero it also jumps up into that corner
192
00:10:30.12 –> 00:10:35.910
because it’s dragged around by its top
193
00:10:33.12 –> 00:10:38.970
right-hand corner handle that’s where
194
00:10:35.91 –> 00:10:41.610
the object is now referenced to so it’s
195
00:10:38.97 –> 00:10:43.230
important that you understand the use of
196
00:10:41.61 –> 00:10:46.699
this little square here because that’s
197
00:10:43.23 –> 00:10:50.459
how you need to position your work
198
00:10:46.699 –> 00:10:53.339
reference to zero zero we’re not going
199
00:10:50.459 –> 00:10:56.130
to position our work to zero zero we’re
200
00:10:53.339 –> 00:10:59.279
going to position our circle to actually
201
00:10:56.13 –> 00:11:01.410
30 30
202
00:10:59.279 –> 00:11:03.660
now that would cut a circle that just
203
00:11:01.41 –> 00:11:05.779
touched our reference square now the
204
00:11:03.66 –> 00:11:08.730
chances are that we don’t want that so
205
00:11:05.779 –> 00:11:15.300
just for guidance what I would tend to
206
00:11:08.73 –> 00:11:18.140
do is draw a rectangle on here and set
207
00:11:15.3 –> 00:11:18.140
this rectangle
208
00:11:19.27 –> 00:11:27.010
at position 30 30 so now you know
209
00:11:24.73 –> 00:11:29.470
exactly where your reference square is
210
00:11:27.01 –> 00:11:34.180
and you can even give it a different
211
00:11:29.47 –> 00:11:38.470
color put it on a separate layer like
212
00:11:34.18 –> 00:11:41.589
that and make that a non cutting layer
213
00:11:38.47 –> 00:11:43.959
is output no so now you’ve got a
214
00:11:41.589 –> 00:11:46.180
reference there and that defines the
215
00:11:43.959 –> 00:11:49.959
table area that you can work in and
216
00:11:46.18 –> 00:11:51.640
where your corner is going to be right
217
00:11:49.959 –> 00:11:54.820
so if I now want to cut that circle at a
218
00:11:51.64 –> 00:11:56.920
specific position let’s just say that
219
00:11:54.82 –> 00:12:00.610
relative to that top right hand corner I
Transcript for Laser Job Positioning and Virtual Arrays (Cont…)
220
00:11:56.92 –> 00:12:03.010
want to move it in by 10 and 10 then
221
00:12:00.61 –> 00:12:05.440
basically I’ve got to remember that my
222
00:12:03.01 –> 00:12:13.950
corner is 30 30 and the top corner of
223
00:12:05.44 –> 00:12:13.950
that circle is now going to be 40 and 40
224
00:12:14.16 –> 00:12:18.220
we’re going to cut it I don’t know
225
00:12:16.899 –> 00:12:21.279
what’s in material I’m going to be using
226
00:12:18.22 –> 00:12:23.320
probably something like some I might use
227
00:12:21.279 –> 00:12:25.540
some plywood okay so we use a small
228
00:12:23.32 –> 00:12:27.550
piece of plywood and that’s probably
229
00:12:25.54 –> 00:12:31.209
going to be cutting three millimetre
230
00:12:27.55 –> 00:12:35.880
plywood probably cut that around about
231
00:12:31.209 –> 00:12:39.220
15 or maybe 20 millimetres a second and
232
00:12:35.88 –> 00:12:43.990
blowing yes scanning we’re gonna cut and
233
00:12:39.22 –> 00:12:45.820
we’re gonna have power 70% okay so
234
00:12:43.99 –> 00:12:48.339
that’s my circle I’m going to cut that
235
00:12:45.82 –> 00:12:49.810
circle relative to that corner 10
236
00:12:48.339 –> 00:12:54.329
millimetres in from the edge of my
237
00:12:49.81 –> 00:12:57.070
material now I’m also going to put a
238
00:12:54.329 –> 00:12:59.950
subtext in there I could put a picture
239
00:12:57.07 –> 00:13:01.959
in there but let’s just put text in and
240
00:12:59.95 –> 00:13:04.870
we’ll make it some sort of fancy text
241
00:13:01.959 –> 00:13:07.750
should we let’s do something silly like
242
00:13:04.87 –> 00:13:10.490
Bauhaus it doesn’t really matter
243
00:13:07.75 –> 00:13:16.430
100% width
244
00:13:10.49 –> 00:13:19.880
and we’ll have characters that maybe
245
00:13:16.43 –> 00:13:23.690
let’s just see what 10 looks like yeah
246
00:13:19.88 –> 00:13:27.590
that’s okay first of all I’m going to
247
00:13:23.69 –> 00:13:31.400
ungroup all of that lot then I’m going
248
00:13:27.59 –> 00:13:36.320
to group that one group then I’m going
249
00:13:31.4 –> 00:13:41.530
to group this one group then I’m going
250
00:13:36.32 –> 00:13:41.530
to group this one group
251
00:13:43.54 –> 00:13:47.800
the whole lot I’m going to mark the
252
00:13:45.85 –> 00:13:52.830
whole lot and I’m going to specify it to
253
00:13:47.8 –> 00:13:55.500
be sent centralized and vertically and
254
00:13:52.83 –> 00:13:59.160
there we go now it’s justified
Transcript for Laser Job Positioning and Virtual Arrays (Cont…)
255
00:13:55.5 –> 00:14:04.660
now put the whole lot back into a group
256
00:13:59.16 –> 00:14:06.490
will change it to a blue layer and I can
257
00:14:04.66 –> 00:14:10.690
position all of that because it’s a
258
00:14:06.49 –> 00:14:13.300
group with that as a second object so if
259
00:14:10.69 –> 00:14:16.330
I hold my shift key down press that as a
260
00:14:13.3 –> 00:14:26.020
second object and then ask it to be
261
00:14:16.33 –> 00:14:28.110
centered that way and this way I’ve now
262
00:14:26.02 –> 00:14:31.510
got my text in the middle of my badge
263
00:14:28.11 –> 00:14:34.690
let’s call it that and we set the blue
264
00:14:31.51 –> 00:14:40.680
layer to be a scan layer and we’ll run
265
00:14:34.69 –> 00:14:48.690
that it’s a four hundred his output yes
266
00:14:40.68 –> 00:14:48.690
blowing no processing mode scan
267
00:14:49.889 –> 00:15:00.629
power mmm let’s try about 30% scanning
268
00:14:57.209 –> 00:15:03.749
interval 0.1 doesn’t do now while we’re
269
00:15:00.629 –> 00:15:13.319
looking at this little logo I’m going to
270
00:15:03.749 –> 00:15:18.209
mark it and put it into a group and now
271
00:15:13.319 –> 00:15:21.179
I’m going to ask it for an array now I’m
272
00:15:18.209 –> 00:15:23.910
going to do an array copy here and if we
273
00:15:21.179 –> 00:15:26.100
take a look at this little logo here
274
00:15:23.91 –> 00:15:27.929
which I’m clicking at the moment you’ll
275
00:15:26.1 –> 00:15:30.119
see that there’s a little black dot in
276
00:15:27.929 –> 00:15:31.799
the corner now you need to put the
277
00:15:30.119 –> 00:15:33.029
little black dot at the top right hand
278
00:15:31.799 –> 00:15:34.799
corner which is where you’re going to
279
00:15:33.029 –> 00:15:37.139
build your array from because you’re
280
00:15:34.799 –> 00:15:39.569
going to build it going left and going
281
00:15:37.139 –> 00:15:41.879
downwards exactly as it says here and
282
00:15:39.569 –> 00:15:44.790
we’re going to put three on the top line
283
00:15:41.879 –> 00:15:48.569
and we’re gonna have spacing of five
284
00:15:44.79 –> 00:15:51.689
millimetres between each one and we’re
285
00:15:48.569 –> 00:15:56.910
going to put three downwards and again
286
00:15:51.689 –> 00:15:59.239
five spacing between them okay and there
Transcript for Laser Job Positioning and Virtual Arrays (Cont…)
287
00:15:56.91 –> 00:16:01.559
we go that was nice and simple wasn’t it
288
00:15:59.239 –> 00:16:03.540
let’s have a look what happens right
289
00:16:01.559 –> 00:16:06.319
let’s do a simulation we’ll run it as
290
00:16:03.54 –> 00:16:06.319
fast as we can
291
00:16:11.07 –> 00:16:17.550
so it’s building from the bottom upwards
292
00:16:14.449 –> 00:16:20.310
scanning across whole lines and
293
00:16:17.55 –> 00:16:24.810
everything now only when it’s finished
294
00:16:20.31 –> 00:16:27.800
scanning all of the text will it go and
295
00:16:24.81 –> 00:16:36.060
cut the badges out and here we go
296
00:16:27.8 –> 00:16:39.120
ba-ba-ba-ba-bom 1 2 etc sometimes that’s
297
00:16:36.06 –> 00:16:43.649
not very convenient especially if you’ve
298
00:16:39.12 –> 00:16:45.690
got a very complex engraving and you
299
00:16:43.649 –> 00:16:48.600
don’t want to run the risk of the
300
00:16:45.69 –> 00:16:51.300
engraving shifting relative to the
301
00:16:48.6 –> 00:16:57.000
outside shape and that can happen quite
302
00:16:51.3 –> 00:17:01.319
often for various reasons it would be
303
00:16:57.0 –> 00:17:05.309
very convenient if we could do the text
304
00:17:01.319 –> 00:17:14.280
cut the shape do the text cut the shape
305
00:17:05.309 –> 00:17:17.510
etc so how do we do that I know you say
306
00:17:14.28 –> 00:17:20.510
look we’ve got this feature built into
307
00:17:17.51 –> 00:17:20.510
scanning
308
00:17:22.6 –> 00:17:28.089
independent output let’s try that
309
00:17:30.19 –> 00:17:39.310
no that’s not working is it it’s
310
00:17:32.29 –> 00:17:41.200
probably saving us a lot of time but
311
00:17:39.31 –> 00:17:43.500
it’s still doing all the scanning before
312
00:17:41.2 –> 00:17:45.610
it does the cutting
313
00:17:43.5 –> 00:17:48.430
well there are many things that you
314
00:17:45.61 –> 00:17:51.460
could try for example you could put the
315
00:17:48.43 –> 00:17:53.290
text on this one on one layer and then
316
00:17:51.46 –> 00:17:55.240
the cutting on another layer this one
317
00:17:53.29 –> 00:17:59.380
text on one layer and that one on
Transcript for Laser Job Positioning and Virtual Arrays (Cont…)
318
00:17:55.24 –> 00:18:02.260
another layer trust me it won’t work it
319
00:17:59.38 –> 00:18:05.160
will always do the scanning before it
320
00:18:02.26 –> 00:18:08.440
does the cutting that’s a golden rule
321
00:18:05.16 –> 00:18:12.850
associated with our D works you cannot
322
00:18:08.44 –> 00:18:16.270
beat that rule okay now if we look under
323
00:18:12.85 –> 00:18:17.830
work we shall also find that we’ve got
324
00:18:16.27 –> 00:18:21.240
one of these funny little symbols down
325
00:18:17.83 –> 00:18:25.450
here first of all we must mark the job
326
00:18:21.24 –> 00:18:27.250
and when we come over here but we had
327
00:18:25.45 –> 00:18:29.680
this little array symbol down here this
328
00:18:27.25 –> 00:18:31.990
little positional thing well we’ve got
329
00:18:29.68 –> 00:18:33.520
exactly the same thing here which makes
330
00:18:31.99 –> 00:18:35.050
you think that well you know it’s the
331
00:18:33.52 –> 00:18:39.670
same doing the same thing in a different
332
00:18:35.05 –> 00:18:41.980
area but it’s not over here it’s called
333
00:18:39.67 –> 00:18:45.280
a virtual array so you need to click on
334
00:18:41.98 –> 00:18:48.160
virtual array and when you clicked on it
335
00:18:45.28 –> 00:18:51.430
you should be able to remove your array
336
00:18:48.16 –> 00:18:54.570
direction to the right corner which is
337
00:18:51.43 –> 00:18:58.210
the top right hand corner for you and
338
00:18:54.57 –> 00:19:03.480
now we can specify in here that we want
339
00:18:58.21 –> 00:19:08.110
for instance 3 in X with a spacing of 5
340
00:19:03.48 –> 00:19:12.850
millimeters between them we need 3 in Y
341
00:19:08.11 –> 00:19:15.760
with a spacing of 5 between them we have
342
00:19:12.85 –> 00:19:20.140
to move to a new box of some sort to get
343
00:19:15.76 –> 00:19:23.260
our spacing ok now you notice everything
344
00:19:20.14 –> 00:19:26.010
is dotted here it’s because it’s a
345
00:19:23.26 –> 00:19:28.810
virtual array it’s not a real array
346
00:19:26.01 –> 00:19:32.190
let’s go and have a look what’s happened
347
00:19:28.81 –> 00:19:32.190
when we go and view it this time
348
00:19:32.69 –> 00:19:39.660
where they all gone they’re not there
349
00:19:35.94 –> 00:19:41.299
now if we click on simulation watch what
350
00:19:39.66 –> 00:19:46.830
happens
351
00:19:41.299 –> 00:19:49.170
text outside shape that’s what’s going
352
00:19:46.83 –> 00:19:50.760
to happen here then it’s going to pitch
353
00:19:49.17 –> 00:19:52.470
across to here and do the same thing
354
00:19:50.76 –> 00:19:56.760
then across to here and do the same
Transcript for Laser Job Positioning and Virtual Arrays (Cont…)
355
00:19:52.47 –> 00:20:03.450
thing so now we have got individual scan
356
00:19:56.76 –> 00:20:06.030
cut scan cut scan cut a very useful
357
00:20:03.45 –> 00:20:08.940
feature if you have got hundreds of
358
00:20:06.03 –> 00:20:10.559
these on a big sheet and you want to
359
00:20:08.94 –> 00:20:12.900
start for instance cleaning them or
360
00:20:10.559 –> 00:20:15.030
painting them you might want to stop the
361
00:20:12.9 –> 00:20:17.669
machine and picked four off them out six
362
00:20:15.03 –> 00:20:19.679
of them out and carry on you’ll
363
00:20:17.669 –> 00:20:21.059
obviously need to be careful but of
364
00:20:19.679 –> 00:20:23.520
course you’ve got your corner reference
365
00:20:21.059 –> 00:20:27.090
here so even if you disturbed the job
366
00:20:23.52 –> 00:20:30.570
you can always put the job back plus the
367
00:20:27.09 –> 00:20:33.030
fact that you’re not going to upset the
368
00:20:30.57 –> 00:20:35.760
relative outlines of these positions
369
00:20:33.03 –> 00:20:38.240
because they’re not there they’re not
370
00:20:35.76 –> 00:20:41.340
there until you’ve scanned and cut
371
00:20:38.24 –> 00:20:43.799
scanned and cut so even if you move your
372
00:20:41.34 –> 00:20:47.730
base material it’s not going to be a big
373
00:20:43.799 –> 00:20:51.960
issue to make this a lot more compact
374
00:20:47.73 –> 00:20:56.600
I’m going to reduce this to a scale of
375
00:20:51.96 –> 00:20:56.600
say 50%
376
00:20:57.93 –> 00:21:04.200
bear in mind I’ve got my padlock closed
377
00:21:00.79 –> 00:21:09.280
let’s see what happens
378
00:21:04.2 –> 00:21:11.860
very intelligent isn’t it everything is
379
00:21:09.28 –> 00:21:14.560
changed by 50% just because I’ve changed
380
00:21:11.86 –> 00:21:18.100
one of them right now before we run this
381
00:21:14.56 –> 00:21:20.740
job something I must tell you although
382
00:21:18.1 –> 00:21:23.830
I’ve drawn this green square outside
383
00:21:20.74 –> 00:21:25.720
here for convenience when it comes to
384
00:21:23.83 –> 00:21:27.460
running it on the machine the machine
385
00:21:25.72 –> 00:21:30.250
won’t allow you to run that green square
386
00:21:27.46 –> 00:21:33.730
even though we’ve specified it as do not
387
00:21:30.25 –> 00:21:36.340
cut the actual dimensions are outside
388
00:21:33.73 –> 00:21:39.990
the work area so we must make sure that
389
00:21:36.34 –> 00:21:44.230
this green square is held just inside
390
00:21:39.99 –> 00:21:46.450
the work area like that you must have
391
00:21:44.23 –> 00:21:48.880
this setting here on your machine that’s
392
00:21:46.45 –> 00:21:51.610
plugged into the PC and you must have
393
00:21:48.88 –> 00:21:54.000
this co-ordinate down here set as
394
00:21:51.61 –> 00:21:58.000
absolute coordinate with your machine
395
00:21:54.0 –> 00:22:00.040
connected to the PC both of those are
Transcript for Laser Job Positioning and Virtual Arrays (Cont…)
396
00:21:58.0 –> 00:22:04.150
essential so you cannot actually
397
00:22:00.04 –> 00:22:06.790
transfer this program as a dot ro D file
398
00:22:04.15 –> 00:22:11.200
to another PC that’s connected to the
399
00:22:06.79 –> 00:22:14.230
machine you can save this program as a
400
00:22:11.2 –> 00:22:17.200
dot Rd file in other words save to au
401
00:22:14.23 –> 00:22:19.030
file and all the information stored in
402
00:22:17.2 –> 00:22:20.320
this program will be put into your
403
00:22:19.03 –> 00:22:22.600
machine and you’ll be able to run this
404
00:22:20.32 –> 00:22:25.540
from the machine but the safest way to
405
00:22:22.6 –> 00:22:27.550
run this stuff is to run it on a PC and
406
00:22:25.54 –> 00:22:29.270
program it on a PC that’s connected to
407
00:22:27.55 –> 00:22:32.410
your
408
00:22:29.27 –> 00:22:32.410
[Music]
409
00:22:37.21 –> 00:22:44.700
so there we go virtual array in action
410
00:22:39.9 –> 00:22:44.700
scan scan
411
00:22:45.91 –> 00:22:52.720
this is one way that you can achieve a
412
00:22:49.25 –> 00:22:55.970
datum reference let’s just take this as
413
00:22:52.72 –> 00:22:59.000
an example of something that I want to
414
00:22:55.97 –> 00:23:01.700
make my reference square from now what
415
00:22:59.0 –> 00:23:04.820
I’ve got to do is to make sure that I
416
00:23:01.7 –> 00:23:08.090
lower the bed because there’s a lip just
417
00:23:04.82 –> 00:23:11.510
here and across the back here I need to
418
00:23:08.09 –> 00:23:15.650
make sure that my reference square sits
419
00:23:11.51 –> 00:23:18.020
below that lip and sits on the edge of
420
00:23:15.65 –> 00:23:20.390
the frame around the back here because
421
00:23:18.02 –> 00:23:22.340
this part of the machine is actually
422
00:23:20.39 –> 00:23:24.260
quite square because we don’t have a
423
00:23:22.34 –> 00:23:27.760
great deal of support along this edge
424
00:23:24.26 –> 00:23:31.460
here we need to have this fairly thick
425
00:23:27.76 –> 00:23:35.630
down here and across the back so again
426
00:23:31.46 –> 00:23:38.980
we’re probably going to lose at least 50
427
00:23:35.63 –> 00:23:38.980
mil I would think
428
00:23:39.44 –> 00:23:46.070
so that’s 40 40 I press my origin button
429
00:23:43.04 –> 00:23:48.920
now can see how the smoke
430
00:23:46.07 –> 00:23:50.810
Eddie’s underneath there it was a great
431
00:23:48.92 –> 00:23:53.020
deal of air movement underneath there is
432
00:23:50.81 –> 00:23:53.020
though
Transcript for Laser Job Positioning and Virtual Arrays (Cont…)
433
00:23:59.79 –> 00:24:06.010
and that’s a classic example of what’s
434
00:24:01.68 –> 00:24:10.740
happening inside the honeycomb
435
00:24:06.01 –> 00:24:10.740
there is no escape from the honeycomb
436
00:24:12.029 –> 00:24:14.869
reset
437
00:24:31.6 –> 00:24:37.570
there we go 40 40 so I can use that
438
00:24:35.289 –> 00:24:39.990
square again and again to set my
439
00:24:37.57 –> 00:24:39.990
reference
440
00:24:40.98 –> 00:24:45.270
and of course I shall still have to use
441
00:24:42.57 –> 00:24:48.420
absolute coordinates when I’m drawing in
442
00:24:45.27 –> 00:24:51.450
our D works but there is one major
443
00:24:48.42 –> 00:24:54.690
problem with this approach and the
444
00:24:51.45 –> 00:24:58.410
problem now is this length here is so
445
00:24:54.69 –> 00:25:02.490
long that on beginner to generate a
446
00:24:58.41 –> 00:25:05.340
potential error with my lens I can’t
447
00:25:02.49 –> 00:25:07.860
guarantee that the – I can’t guarantee
448
00:25:05.34 –> 00:25:11.880
the beam is going to pass right down the
449
00:25:07.86 –> 00:25:15.140
true centre of the lens because if we
450
00:25:11.88 –> 00:25:15.140
watch very carefully look
451
00:25:15.37 –> 00:25:19.710
there’s a little bit of clearance in
452
00:25:17.17 –> 00:25:19.710
here and
453
00:25:22.48 –> 00:25:30.270
I’m not pushing and pulling that very
454
00:25:24.82 –> 00:25:30.270
hard but I can move that a millimetre
455
00:25:31.25 –> 00:25:34.700
push it that way
456
00:25:41.21 –> 00:25:43.810
both
457
00:25:46.04 –> 00:25:51.440
so you can clearly see there that we’ve
458
00:25:48.68 –> 00:25:54.020
got two positions vertically and two
459
00:25:51.44 –> 00:25:56.060
positions horizontally that that nozzle
460
00:25:54.02 –> 00:25:58.510
could take up because it’s so far
Transcript for Laser Job Positioning and Virtual Arrays (Cont…)
461
00:25:56.06 –> 00:26:04.120
extended and not very well supported
462
00:25:58.51 –> 00:26:06.710
so all I’m warning about is that’s fine
463
00:26:04.12 –> 00:26:10.370
if you understand what the limitations
464
00:26:06.71 –> 00:26:12.260
are of using this system now in a
465
00:26:10.37 –> 00:26:13.850
situation like this where maybe you want
466
00:26:12.26 –> 00:26:16.400
to engrave on the surface of a block
467
00:26:13.85 –> 00:26:17.870
because you’ve got some height here it’s
468
00:26:16.4 –> 00:26:21.080
another problem because we’ve pulled the
469
00:26:17.87 –> 00:26:23.450
nozzle right up and we’re still on this
470
00:26:21.08 –> 00:26:25.670
piece of metal here we could go down
471
00:26:23.45 –> 00:26:27.590
with the table quite a long way so this
472
00:26:25.67 –> 00:26:29.240
is a very convenient way for instance if
473
00:26:27.59 –> 00:26:31.330
you’re engraving on the surface of a box
474
00:26:29.24 –> 00:26:33.680
or something and you want a reference
475
00:26:31.33 –> 00:26:35.390
now finally I’m going to show you a
476
00:26:33.68 –> 00:26:35.810
slightly different approach to the
477
00:26:35.39 –> 00:26:40.670
problem
478
00:26:35.81 –> 00:26:44.150
which may suit some people now this is
479
00:26:40.67 –> 00:26:47.180
using my solid metal table when I first
480
00:26:44.15 –> 00:26:50.240
made this it sits over the table and
481
00:26:47.18 –> 00:26:53.750
snuggles in but it’s not absolutely
482
00:26:50.24 –> 00:26:57.800
perfect and error free it’s not movement
483
00:26:53.75 –> 00:27:01.700
free so what I had to do was to cut a
484
00:26:57.8 –> 00:27:04.760
small slot in here at the end of each
485
00:27:01.7 –> 00:27:08.120
side and then I went in there with my
486
00:27:04.76 –> 00:27:10.130
screwdriver and I very carefully bent it
487
00:27:08.12 –> 00:27:12.440
up just to increase the overall length
488
00:27:10.13 –> 00:27:17.650
because I made it wrong by maybe a
489
00:27:12.44 –> 00:27:17.650
millimetre so now when I put the totally
490
00:27:20.08 –> 00:27:24.769
it sits in there and does not move at
491
00:27:24.2 –> 00:27:27.500
all
492
00:27:24.769 –> 00:27:30.860
no I’ll wear that lots of people use
493
00:27:27.5 –> 00:27:33.559
these machines for producing trinkets at
494
00:27:30.86 –> 00:27:36.260
craft fairs for Christmas for birthdays
495
00:27:33.559 –> 00:27:38.830
for all sorts of celebration occasions
496
00:27:36.26 –> 00:27:38.830
and
497
00:27:39.19 –> 00:27:46.360
they have lots of these already made
498
00:27:42.84 –> 00:27:49.600
standard on the shelf now here’s one
499
00:27:46.36 –> 00:27:52.180
that I produced earlier absolute rubbish
500
00:27:49.6 –> 00:27:55.150
but hey it demonstrates the point it’s
501
00:27:52.18 –> 00:27:58.210
not for sale so no you can’t have one
Transcript for Laser Job Positioning and Virtual Arrays (Cont…)
502
00:27:55.15 –> 00:28:02.590
even if you ask for one what we do we
503
00:27:58.21 –> 00:28:06.370
manufacture the whole of the unit the
504
00:28:02.59 –> 00:28:10.720
cutting the hole the butterfly the the
505
00:28:06.37 –> 00:28:15.040
logo but we leave off the red layer
506
00:28:10.72 –> 00:28:17.760
which is the personalization so we’ll go
507
00:28:15.04 –> 00:28:17.760
to the red layer
508
00:28:20.059 –> 00:28:27.639
and where it says is output we say no
509
00:28:24.19 –> 00:28:32.679
okay so everything will be cut and
510
00:28:27.639 –> 00:28:32.679
engraved on there except the red layer
511
00:28:32.98 –> 00:28:38.539
and now what we’re going to do we’re
512
00:28:35.679 –> 00:28:43.209
going to come down here
513
00:28:38.539 –> 00:28:43.209
and we’re going to specify to
514
00:28:44.23 –> 00:28:50.390
with a five mil spacing
515
00:28:47.55 –> 00:28:50.390
and to
516
00:28:50.86 –> 00:28:56.150
with a five mil spacing and touch any
517
00:28:54.04 –> 00:29:01.390
other box
518
00:28:56.15 –> 00:29:04.610
and there we go and we’ve removed the
519
00:29:01.39 –> 00:29:07.700
absolute and we put it back to current
520
00:29:04.61 –> 00:29:11.330
position so that I can specify this
521
00:29:07.7 –> 00:29:13.460
starting point for the head on the
522
00:29:11.33 –> 00:29:16.610
material that have available and I can
523
00:29:13.46 –> 00:29:18.770
also lift it off the deck on my spaces
524
00:29:16.61 –> 00:29:20.840
for cutting so that it doesn’t actually
525
00:29:18.77 –> 00:29:25.420
mark the back so I’ll just put my
526
00:29:20.84 –> 00:29:31.480
spacers my standoffs towards the corners
527
00:29:25.42 –> 00:29:36.530
because these acrylic we want nice white
528
00:29:31.48 –> 00:29:38.540
characters but we don’t want white
529
00:29:36.53 –> 00:29:40.400
spilled around the outside of the
530
00:29:38.54 –> 00:29:44.420
characters and the logos and the letters
531
00:29:40.4 –> 00:29:46.490
so we’ve left the covering on now with a
532
00:29:44.42 –> 00:29:48.860
fairly complicated shape like this
533
00:29:46.49 –> 00:29:51.380
butterfly it’s a little bit of a pain to
534
00:29:48.86 –> 00:29:54.080
take the pieces off afterwards but if
535
00:29:51.38 –> 00:29:57.410
you’re doing it beforehand so you
536
00:29:54.08 –> 00:30:00.160
haven’t got to do it on the day all of a
Transcript for Laser Job Positioning and Virtual Arrays (Cont…)
537
00:29:57.41 –> 00:30:02.590
sudden it becomes easy
538
00:30:00.16 –> 00:30:04.690
because you can do this in your spare
539
00:30:02.59 –> 00:30:06.940
time so you want to get as much of this
540
00:30:04.69 –> 00:30:09.210
preparation work done as you possibly
541
00:30:06.94 –> 00:30:09.210
can
542
00:30:12.0 –> 00:30:15.130
[Music]
543
00:30:17.32 –> 00:30:23.490
so there we are engrave and cut using
544
00:30:20.23 –> 00:30:23.490
the virtual array
545
00:30:25.95 –> 00:30:31.489
so what I’ve now done
546
00:30:28.58 –> 00:30:34.700
I’ve sellotaped a piece of material onto
547
00:30:31.489 –> 00:30:36.979
the table it could be any material it
548
00:30:34.7 –> 00:30:38.629
doesn’t have to be the same material and
549
00:30:36.979 –> 00:30:41.779
what we’re going to do now from the same
550
00:30:38.629 –> 00:30:44.539
file we just suppress the butterfly
551
00:30:41.779 –> 00:30:46.519
layer and the text layer and the only
552
00:30:44.539 –> 00:30:50.349
layer that’s left is the cut layer take
553
00:30:46.519 –> 00:30:50.349
this down to five millimetres
554
00:30:52.7 –> 00:30:57.440
okay so we can set our origin now at
555
00:30:55.129 –> 00:30:59.960
that point there press the origin button
556
00:30:57.44 –> 00:31:01.460
under no circumstances touch the origin
557
00:30:59.96 –> 00:31:06.279
button again now I’ve suppressed
558
00:31:01.46 –> 00:31:06.279
everything except the cut layer
559
00:31:10.04 –> 00:31:18.310
but pull a piece of tape up backing like
560
00:31:12.89 –> 00:31:18.310
that I should be able to lift it out
561
00:31:19.35 –> 00:31:25.770
now drop that one in I’m going to put
562
00:31:23.19 –> 00:31:29.130
the red layer back on which is the text
563
00:31:25.77 –> 00:31:32.250
layer these output for the cut layer no
564
00:31:29.13 –> 00:31:34.559
I don’t want it to cut again all I want
565
00:31:32.25 –> 00:31:36.539
is the red layer so everything is
566
00:31:34.559 –> 00:31:39.030
perfectly lined up I can move the
567
00:31:36.539 –> 00:31:41.850
drawing around in our D works it makes
568
00:31:39.03 –> 00:31:44.760
no difference because I’ve got current
569
00:31:41.85 –> 00:31:47.640
set and current is always from this
570
00:31:44.76 –> 00:31:49.740
corner of the work so provided that
571
00:31:47.64 –> 00:31:51.900
don’t move the origin point on the
572
00:31:49.74 –> 00:31:52.590
machine here it will always start at
Transcript for Laser Job Positioning and Virtual Arrays (Cont…)
573
00:31:51.9 –> 00:32:07.369
this point
574
00:31:52.59 –> 00:32:07.369
[Music]
575
00:32:10.33 –> 00:32:16.109
and here we go we put the next one in
576
00:32:12.839 –> 00:32:16.109
press run
577
00:32:31.41 –> 00:32:37.100
and then while that’s going on I can be
578
00:32:34.32 –> 00:32:37.100
peeling this off
579
00:32:54.48 –> 00:32:57.849
[Music]
580
00:32:58.08 –> 00:33:01.760
and provided it’s not clear
581
00:33:07.71 –> 00:33:13.820
and provided it’s not clear material I
582
00:33:10.05 –> 00:33:13.820
can give it a puff of isopropyl alcohol
583
00:33:21.09 –> 00:33:26.879
and quickly give it a nice shine well
584
00:33:25.83 –> 00:33:29.399
here we are at the end of another
585
00:33:26.879 –> 00:33:31.919
session I hope some of that will be of
586
00:33:29.399 –> 00:33:34.730
use to you so until the next time
587
00:33:31.919 –> 00:33:34.730
cheerio
