2
00:00:14.09 –> 00:00:20.310
well welcome to another LightBlade

3
00:00:16.5 –> 00:00:22.860
Learning Lab today the title of the

4
00:00:20.31 –> 00:00:25.500
piece tells it all we’re going to use

5
00:00:22.86 –> 00:00:28.410
some of this a for Baltic birch plywood

6
00:00:25.5 –> 00:00:29.930
which is three millimeters thick to try

7
00:00:28.41 –> 00:00:34.440
and make some puzzles

8
00:00:29.93 –> 00:00:36.540
now jigsaw puzzles are on the surface of

9
00:00:34.44 –> 00:00:38.520
it quite simple to make once you’ve got

10
00:00:36.54 –> 00:00:41.910
the design sorted out but manufacturing

11
00:00:38.52 –> 00:00:45.809
it so that is a really nice neat piece

12
00:00:41.91 –> 00:00:48.360
of work is much more difficult so today

13
00:00:45.809 –> 00:00:50.720
I’m going to show you first of all the

14
00:00:48.36 –> 00:00:53.250
problems that we’re going to have and

15
00:00:50.72 –> 00:00:55.530
then we’re going to try and find a

16
00:00:53.25 –> 00:00:58.470
solution now so try and find a solution

17
00:00:55.53 –> 00:01:00.060
because I’ve not done this before and so

18
00:00:58.47 –> 00:01:02.640
we’re going to jump into something very

19
00:01:00.06 –> 00:01:05.009
new which I’m moderately confident will

20
00:01:02.64 –> 00:01:06.869
solve the problem now let’s forget the

21
00:01:05.009 –> 00:01:09.119
details of the puzzle itself at the

22
00:01:06.869 –> 00:01:13.049
moment and look at the physical problems

23
00:01:09.119 –> 00:01:15.450
that we’re going to face I don’t think

24
00:01:13.049 –> 00:01:18.150
that’s necessarily a good idea to use

25
00:01:15.45 –> 00:01:19.710
this table to cut this to cut this

26
00:01:18.15 –> 00:01:21.870
puzzle on because first of all all the

27
00:01:19.71 –> 00:01:23.760
pieces will fall down inside some of

28
00:01:21.87 –> 00:01:25.710
them will get trapped in here and as

29
00:01:23.76 –> 00:01:28.470
they get trapped in here what will

30
00:01:25.71 –> 00:01:31.130
happen is the cut as it carries on will

31
00:01:28.47 –> 00:01:33.450
mark the pieces that are trapped in here

32
00:01:31.13 –> 00:01:36.900
you know you’ve just got no control of

33
00:01:33.45 –> 00:01:39.330
where the pieces are going to fall that

34
00:01:36.9 –> 00:01:42.560
tells us that before we start we’ve got

35
00:01:39.33 –> 00:01:46.530
to retain the puzzle in one flat plane

36
00:01:42.56 –> 00:01:49.440
complete while it’s being cut so that

37
00:01:46.53 –> 00:01:52.049
leaves us with this second option which

38
00:01:49.44 –> 00:01:53.880
is the honeycomb table when you’re

39
00:01:52.049 –> 00:01:56.159
cutting wood you can see what happens on

40
00:01:53.88 –> 00:01:58.799
the end look we’ve got all sorts of

41
00:01:56.159 –> 00:02:01.360
brown muck in here which when we pass

42
00:01:58.799 –> 00:02:05.140
the laser beam over the top of it

43
00:02:01.36 –> 00:02:09.580
it’s going to blow up horrible foods at

44
00:02:05.14 –> 00:02:12.580
the back and mark the back of the job so

45
00:02:09.58 –> 00:02:15.460
let’s just test this as an idea to start

46
00:02:12.58 –> 00:02:17.170
with right well I’ve got a 2-inch lens

47
00:02:15.46 –> 00:02:19.930
in here here’s the material that we’re

48
00:02:17.17 –> 00:02:23.170
going to be using and it’s a nice white

49
00:02:19.93 –> 00:02:27.610
of Baltic birch plywood I’ve got a two

50
00:02:23.17 –> 00:02:29.200
inch gallium arsenide lens in here which

51
00:02:27.61 –> 00:02:31.200
will be one of the standard lenses that

52
00:02:29.2 –> 00:02:33.660
you’re supplied with

53
00:02:31.2 –> 00:02:36.540
and I’m just going to run a test square

54
00:02:33.66 –> 00:02:40.910
up in this corner I’m running at about

55
00:02:36.54 –> 00:02:40.910
25 millilitres a second on full power

56
00:02:42.4 –> 00:02:45.569
[Music]

57
00:02:46.09 –> 00:02:51.790
and I think as you can clearly see we’ve

58
00:02:49.43 –> 00:02:55.580
got all these marks around the pieces

59
00:02:51.79 –> 00:02:57.800
which is where the laser beam has jumped

60
00:02:55.58 –> 00:03:00.320
over these small pieces of honeycomb

61
00:02:57.8 –> 00:03:02.300
although this solves one problem ie it

62
00:03:00.32 –> 00:03:06.440
keeps all the pieces in one plane and

63
00:03:02.3 –> 00:03:08.420
together if you’re happy to accept this

64
00:03:06.44 –> 00:03:09.980
on the back of your puzzle because it’s

65
00:03:08.42 –> 00:03:12.770
only for your own use

66
00:03:09.98 –> 00:03:16.100
then go ahead use your honeycomb table

67
00:03:12.77 –> 00:03:19.130
but to me that’s totally unprofessional

68
00:03:16.1 –> 00:03:21.500
and the wrong approach if you’re trying

69
00:03:19.13 –> 00:03:23.540
to sell bespoke puzzles for example to

70
00:03:21.5 –> 00:03:25.250
somebody you certainly won’t want all

71
00:03:23.54 –> 00:03:30.020
these marks on the back of your pieces

72
00:03:25.25 –> 00:03:32.060
very unprofessional so we need to start

73
00:03:30.02 –> 00:03:35.420
looking for something as an alternative

74
00:03:32.06 –> 00:03:37.880
backing material my first reaction was

75
00:03:35.42 –> 00:03:41.240
hey let’s have something that doesn’t

76
00:03:37.88 –> 00:03:43.100
cause smoke something that won’t burn

77
00:03:41.24 –> 00:03:46.970
and here we are look we’ve got a piece

78
00:03:43.1 –> 00:03:49.450
of polished granite this doesn’t burn we

79
00:03:46.97 –> 00:03:51.860
won’t get any blowback off the surface

80
00:03:49.45 –> 00:03:53.720
so I’m going to leave the extraction off

81
00:03:51.86 –> 00:03:58.050
so that we can see what happens

82
00:03:53.72 –> 00:03:58.050
[Music]

83
00:04:00.93 –> 00:04:05.230
not huge amounts of smoke there’s a good

84
00:04:04.269 –> 00:04:07.230
reason for that

85
00:04:05.23 –> 00:04:09.540
[Music]

86
00:04:07.23 –> 00:04:12.680
although it’s a lovely nice clean cut on

87
00:04:09.54 –> 00:04:12.680
the top as you can see

88
00:04:13.03 –> 00:04:17.350
let’s take a look underneath well the

89
00:04:15.64 –> 00:04:20.680
reason why we didn’t have too much smoke

90
00:04:17.35 –> 00:04:23.560
coming upwards was because it all went

91
00:04:20.68 –> 00:04:25.600
downwards we mostly damage the surface

92
00:04:23.56 –> 00:04:28.060
here but look we’ve got all sorts of

93
00:04:25.6 –> 00:04:30.850
sticky brown stuff on it which is the

94
00:04:28.06 –> 00:04:32.740
fumes that have actually vaporized on

95
00:04:30.85 –> 00:04:36.100
this cold surface as they’ve been blown

96
00:04:32.74 –> 00:04:38.680
through the job and look those same

97
00:04:36.1 –> 00:04:40.840
fumes which are in a liquid sticky form

98
00:04:38.68 –> 00:04:45.210
have also they’ve done a huge amount of

99
00:04:40.84 –> 00:04:48.880
damage red on the outside of our cut so

100
00:04:45.21 –> 00:04:51.100
very very very unsatisfactory so that’s

101
00:04:48.88 –> 00:04:53.490
not a solution to our problem we’ve got

102
00:04:51.1 –> 00:04:56.740
to find a way of getting the fumes

103
00:04:53.49 –> 00:04:59.470
cleanly out the bottom of the job so

104
00:04:56.74 –> 00:05:01.780
that they can get extracted away and we

105
00:04:59.47 –> 00:05:05.469
don’t get any reflections off of pieces

106
00:05:01.78 –> 00:05:08.210
of material that are supporting the job

107
00:05:05.469 –> 00:05:11.059
that sounds like an almost impossible

108
00:05:08.21 –> 00:05:13.339
task when it comes to cutting jigsaw

109
00:05:11.059 –> 00:05:17.139
puzzles which are whole load of separate

110
00:05:13.339 –> 00:05:20.479
pieces yeah we need sky hooks to hang on

111
00:05:17.139 –> 00:05:25.129
and I’m afraid I don’t know how to make

112
00:05:20.479 –> 00:05:27.050
sky hooks but I am gonna have a go at

113
00:05:25.129 –> 00:05:30.830
trying to make something which is a

114
00:05:27.05 –> 00:05:32.479
closed alternative to a sky book now

115
00:05:30.83 –> 00:05:36.169
kill the guards function that basically

116
00:05:32.479 –> 00:05:38.689
is made up of two small pieces base

117
00:05:36.169 –> 00:05:42.349
plate and a top plate I’m going to

118
00:05:38.689 –> 00:05:46.219
assembly this onto this top plate rather

119
00:05:42.349 –> 00:05:49.300
than onto the base plate so speed is of

120
00:05:46.219 –> 00:05:53.180
the essence why are we doing this part

121
00:05:49.3 –> 00:05:55.039
okay so here’s our assembly if we look

122
00:05:53.18 –> 00:06:02.449
through it we should see that we’ve got

Transcript of Making a Wooden Laser Cut Jigsaw Puzzle (Cont…)

123
00:05:55.039 –> 00:06:05.479
a clear passage way underneath here for

124
00:06:02.449 –> 00:06:08.899
the air to flow through underneath this

125
00:06:05.479 –> 00:06:11.149
plate and as expected it’s a nice snug

126
00:06:08.899 –> 00:06:14.389
fit for a piece of plywood we’ve got a

127
00:06:11.149 –> 00:06:15.979
solid surface behind here so we’re going

128
00:06:14.389 –> 00:06:18.199
to produce exactly the same effect that

129
00:06:15.979 –> 00:06:20.810
we did here if we’re not careful we’re

130
00:06:18.199 –> 00:06:23.749
going to get debris which condenses on

131
00:06:20.81 –> 00:06:26.930
this surface and runs out behind the cut

132
00:06:23.749 –> 00:06:29.539
we need to make sure that the fumes that

133
00:06:26.93 –> 00:06:32.599
we produce during cutting go right the

134
00:06:29.539 –> 00:06:36.319
way through the job and then we can put

135
00:06:32.599 –> 00:06:39.080
air underneath here remember where it’s

136
00:06:36.319 –> 00:06:41.839
a nice clear passageway and get sucked

137
00:06:39.08 –> 00:06:47.139
away so somehow we’re going to have to

138
00:06:41.839 –> 00:06:50.419
pre-cut this in the shape of the puzzle

139
00:06:47.139 –> 00:06:52.430
so that the track when we cut the puzzle

140
00:06:50.419 –> 00:06:56.360
the foods past right the way through

141
00:06:52.43 –> 00:07:00.199
here to do that means that we’ve really

142
00:06:56.36 –> 00:07:04.719
got to bolt this fixture down onto the

143
00:07:00.199 –> 00:07:08.659
table which is nice and solid so that

144
00:07:04.719 –> 00:07:10.699
once we’ve cut the track in here we can

145
00:07:08.659 –> 00:07:13.310
immediately replicate that

146
00:07:10.699 –> 00:07:14.840
when we come to cut the puzzle we don’t

147
00:07:13.31 –> 00:07:17.180
want the puzzle to be cut over a

148
00:07:14.84 –> 00:07:20.870
different track than the cuts that we’ve

149
00:07:17.18 –> 00:07:24.830
pre produced in here now to do that we

150
00:07:20.87 –> 00:07:25.909
can’t rely on any external location so

151
00:07:24.83 –> 00:07:28.189
we’re going to have to use a feature

152
00:07:25.909 –> 00:07:32.900
that’s available on this machine a

153
00:07:28.189 –> 00:07:35.780
feature called absolute mode and let me

154
00:07:32.9 –> 00:07:38.020
explain what absolute mode is for those

155
00:07:35.78 –> 00:07:42.919
of you that have never used it before

156
00:07:38.02 –> 00:07:46.810
well here I’ve drawn a sheet of a4 size

157
00:07:42.919 –> 00:07:51.620
material and across the center line here

158
00:07:46.81 –> 00:07:54.319
I’ve drawn two holes just here and here

159
00:07:51.62 –> 00:07:58.159
now these are going to be the fixing

160
00:07:54.319 –> 00:08:00.500
holes that I used on my jig I’m going to

Transcript of Making a Wooden Laser Cut Jigsaw Puzzle (Cont…)

161
00:07:58.159 –> 00:08:03.979
have to put these holes into the base

162
00:08:00.5 –> 00:08:06.710
plate of my machine so that whenever I

163
00:08:03.979 –> 00:08:10.370
put this jig back into the Machine I

164
00:08:06.71 –> 00:08:12.169
will know exactly where the coordinates

165
00:08:10.37 –> 00:08:16.430
where the program is going to run

166
00:08:12.169 –> 00:08:19.879
because I have changed this feature here

167
00:08:16.43 –> 00:08:21.849
called position from current to

168
00:08:19.879 –> 00:08:24.740
something called absolute coordinates

169
00:08:21.849 –> 00:08:27.169
now what that means is you will not be

170
00:08:24.74 –> 00:08:29.060
able to use the the origin button on

171
00:08:27.169 –> 00:08:31.819
your machine so what I’m going to have

172
00:08:29.06 –> 00:08:35.690
to do eventually is to draw our puzzle

173
00:08:31.819 –> 00:08:38.149
picture on top of this template because

174
00:08:35.69 –> 00:08:41.659
this is a template that is going to

175
00:08:38.149 –> 00:08:44.449
allow me to always replicate exactly the

176
00:08:41.659 –> 00:08:47.029
position of this piece of a4 material

177
00:08:44.449 –> 00:08:49.640
and my program will always work with

178
00:08:47.029 –> 00:08:52.279
exactly the same coordinates that I

179
00:08:49.64 –> 00:08:54.620
programmed and run in this machine so if

180
00:08:52.279 –> 00:08:57.350
I set my piece of iturra

181
00:08:54.62 –> 00:09:00.110
at the top here it will always run up

182
00:08:57.35 –> 00:09:03.350
here so positioning of this is not super

183
00:09:00.11 –> 00:09:06.709
important it’s conveniently wherever you

184
00:09:03.35 –> 00:09:08.930
want it on your machine bed I dropped

185
00:09:06.709 –> 00:09:11.750
mine here and that’s where it’ll be

186
00:09:08.93 –> 00:09:15.320
forever when I use absolute coordinates

187
00:09:11.75 –> 00:09:18.140
so that means that you must save this

188
00:09:15.32 –> 00:09:20.690
picture here as an r OD file because

189
00:09:18.14 –> 00:09:22.300
this is going to become a template for

190
00:09:20.69 –> 00:09:25.480
any other program that you

191
00:09:22.3 –> 00:09:27.280
to run on a for material in this jig or

192
00:09:25.48 –> 00:09:30.790
another jig that you might want to

193
00:09:27.28 –> 00:09:32.410
design around the same fixing holes so

194
00:09:30.79 –> 00:09:35.080
once we’ve got the fixing holes in the

195
00:09:32.41 –> 00:09:37.300
machine we’ve effectively got a new

196
00:09:35.08 –> 00:09:40.510
reference position which we can

197
00:09:37.3 –> 00:09:42.970
replicate every time I’m going to find a

198
00:09:40.51 –> 00:09:45.820
way to put these holes into my machine

199
00:09:42.97 –> 00:09:47.710
bed exactly where I’ve drawn them and to

200
00:09:45.82 –> 00:09:51.070
do that what I’m going to do is to put

201
00:09:47.71 –> 00:09:53.890
the holes on a different layer so let’s

202
00:09:51.07 –> 00:09:57.120
put them onto a red layer okay so we’re

203
00:09:53.89 –> 00:10:01.560
now come up to the top here and we’ll

Transcript of Making a Wooden Laser Cut Jigsaw Puzzle (Cont…)

204
00:09:57.12 –> 00:10:07.480
set the red layer to cut some holes

205
00:10:01.56 –> 00:10:10.740
seven millimeters yeah Polish power yes

206
00:10:07.48 –> 00:10:13.600
that’ll do so it’s a cut layer

207
00:10:10.74 –> 00:10:16.060
okay now the black layer will check the

208
00:10:13.6 –> 00:10:18.820
black layer and it says here do you want

209
00:10:16.06 –> 00:10:19.930
an output well the answer is no and it

210
00:10:18.82 –> 00:10:23.680
doesn’t matter what any of the other

211
00:10:19.93 –> 00:10:27.010
settings are now so these spacings here

212
00:10:23.68 –> 00:10:30.010
are roughly 50 millimetres apart on this

213
00:10:27.01 –> 00:10:32.230
grid so one two three it’s just over a

214
00:10:30.01 –> 00:10:34.120
hundred and fifty millimetres about 160

215
00:10:32.23 –> 00:10:36.490
millimetres up from the bottom edge of

216
00:10:34.12 –> 00:10:39.460
the table I’ve got a strip of material

217
00:10:36.49 –> 00:10:40.840
here acrylic it doesn’t matter what it

218
00:10:39.46 –> 00:10:45.130
is this is happens to be about five

219
00:10:40.84 –> 00:10:46.750
millimetres thick so roughly 160

220
00:10:45.13 –> 00:10:49.810
millimetres up from the bottom edge of

221
00:10:46.75 –> 00:10:51.100
the table we’ll set that across there

222
00:10:49.81 –> 00:11:03.330
like that

223
00:10:51.1 –> 00:11:03.330
[Music]

224
00:11:03.75 –> 00:11:07.220
put a little bit of tension on it

225
00:11:09.98 –> 00:11:16.160
is to make sure that piece of plastic is

226
00:11:12.68 –> 00:11:19.850
not going to move and there we go that’s

227
00:11:16.16 –> 00:11:21.680
pretty solid now as you can see the

228
00:11:19.85 –> 00:11:25.430
table has got a small amount of movement

229
00:11:21.68 –> 00:11:28.040
in it this way but I purposely made it

230
00:11:25.43 –> 00:11:30.950
so that it’s got nothing in it sideways

231
00:11:28.04 –> 00:11:32.570
but what we can do is to remove the

232
00:11:30.95 –> 00:11:37.100
clearance in the table backwards and

233
00:11:32.57 –> 00:11:40.370
forwards with that small peg so now

234
00:11:37.1 –> 00:11:42.890
we’ve got a completely solid table no

235
00:11:40.37 –> 00:11:45.650
movement so we need to just set the

236
00:11:42.89 –> 00:11:47.590
focus correctly run this program all I’m

237
00:11:45.65 –> 00:11:50.820
going to do is going to get two holes

238
00:11:47.59 –> 00:11:53.949
punched through the material just there

239
00:11:50.82 –> 00:11:53.949
[Music]

240
00:11:57.57 –> 00:12:01.390
simple as that

Transcript of Making a Wooden Laser Cut Jigsaw Puzzle (Cont…)

241
00:11:58.87 –> 00:12:09.790
except I’ve now got to get these little

242
00:12:01.39 –> 00:12:15.700
pieces out click we now remove our

243
00:12:09.79 –> 00:12:22.300
cutting template and I’ve got an m4 tap

244
00:12:15.7 –> 00:12:25.690
here now hopefully I’ve got nothing

245
00:12:22.3 –> 00:12:28.240
underneath there to get in the way of my

246
00:12:25.69 –> 00:12:30.550
screws I just check I can now screw my

247
00:12:28.24 –> 00:12:34.930
fixture down to the table with two

248
00:12:30.55 –> 00:12:38.140
screws and I know exactly where my sheet

249
00:12:34.93 –> 00:12:40.300
of a4 material is going to be relative

250
00:12:38.14 –> 00:12:42.910
to the zero zero of the machine and

251
00:12:40.3 –> 00:12:45.880
whenever I run this program it will

252
00:12:42.91 –> 00:12:47.320
always be in exactly the same place now

253
00:12:45.88 –> 00:12:49.570
obviously you can’t do it if you’ve got

254
00:12:47.32 –> 00:12:52.120
one of these floating around and it only

255
00:12:49.57 –> 00:12:54.490
works if you can get an absolutely

256
00:12:52.12 –> 00:12:57.150
stable base to bog it too

257
00:12:54.49 –> 00:13:00.289
we’re going to create our own picture

258
00:12:57.15 –> 00:13:00.289
[Music]

259
00:13:01.65 –> 00:13:05.170
nobody shouldn’t complain about the

260
00:13:03.58 –> 00:13:08.070
lovely lady like a holiday

261
00:13:05.17 –> 00:13:10.560
[Music]

262
00:13:08.07 –> 00:13:13.110
so we know exactly where this a4 sheet

263
00:13:10.56 –> 00:13:16.079
is and any pattern that we draw on it

264
00:13:13.11 –> 00:13:18.870
will be the program will be referenced

265
00:13:16.079 –> 00:13:21.149
to zero zero in the corner there now

266
00:13:18.87 –> 00:13:24.480
this is everything that you want to know

267
00:13:21.149 –> 00:13:28.319
about the a4 puzzle on one sheet of

268
00:13:24.48 –> 00:13:29.339
paper so we need to zoom out and you’ll

269
00:13:28.319 –> 00:13:32.279
see what I mean

270
00:13:29.339 –> 00:13:37.380
so here we’ve got the jig which we don’t

271
00:13:32.279 –> 00:13:39.360
need delete here we’ve got my basic

272
00:13:37.38 –> 00:13:43.740
general arrangement which we don’t need

273
00:13:39.36 –> 00:13:46.579
and we will delete here we’ve got a

274
00:13:43.74 –> 00:13:50.399
layout of what the top plate looks like

275
00:13:46.579 –> 00:13:56.069
with all the little reference squares in

276
00:13:50.399 –> 00:13:59.579
it so it’s just a check delete here

277
00:13:56.069 –> 00:14:01.440
we’ve got the puzzle pattern which we

Transcript of Making a Wooden Laser Cut Jigsaw Puzzle (Cont…)

278
00:13:59.579 –> 00:14:03.480
don’t need at the moment so we delete

279
00:14:01.44 –> 00:14:07.160
that and the only thing we’re left with

280
00:14:03.48 –> 00:14:09.540
is that is this jig preparation template

281
00:14:07.16 –> 00:14:12.480
now I’m going to leave the two holes in

282
00:14:09.54 –> 00:14:16.170
because everything is symmetrical I’m

283
00:14:12.48 –> 00:14:18.149
going to mark that and make that a group

284
00:14:16.17 –> 00:14:20.940
I know that I’ve put the puzzle

285
00:14:18.149 –> 00:14:23.519
symmetrically in this a4 frame I’m going

286
00:14:20.94 –> 00:14:27.029
to mark just the puzzle and not the

287
00:14:23.519 –> 00:14:29.940
frame I’ve got to put it into a group

288
00:14:27.029 –> 00:14:32.130
click on that and we’ll turn that into a

289
00:14:29.94 –> 00:14:35.730
blue Lane I’m going to put handles on

290
00:14:32.13 –> 00:14:39.300
that blue layer now and we are going to

291
00:14:35.73 –> 00:14:44.610
press the shift key and we’re also going

292
00:14:39.3 –> 00:14:48.389
to highlight this other group

293
00:14:44.61 –> 00:14:51.259
and I can now use these alignment tools

294
00:14:48.389 –> 00:14:55.410
at the top here to align at first of all

295
00:14:51.259 –> 00:14:56.629
horizontally and watch this jiggle now

296
00:14:55.41 –> 00:14:59.189
there we go

297
00:14:56.629 –> 00:15:00.809
so it’s now jiggled out of line to its

298
00:14:59.189 –> 00:15:02.459
own reference square but that doesn’t

299
00:15:00.809 –> 00:15:04.439
matter because what we’re doing we’re

300
00:15:02.459 –> 00:15:06.509
lining the patent up with this reference

301
00:15:04.439 –> 00:15:09.360
square we’ve put our pre cutting

302
00:15:06.509 –> 00:15:14.610
template into the correct position on

303
00:15:09.36 –> 00:15:17.579
the jig we can now delete this frame

304
00:15:14.61 –> 00:15:20.730
here because we don’t need it we’ve got

305
00:15:17.579 –> 00:15:23.999
everything that we need just here we

306
00:15:20.73 –> 00:15:26.670
don’t want anything black to cut so

307
00:15:23.999 –> 00:15:31.230
we’ll check the black layer and we’ll

308
00:15:26.67 –> 00:15:33.509
make sure that it says is output no ok

309
00:15:31.23 –> 00:15:34.079
we now check the parameters for the blue

310
00:15:33.509 –> 00:15:38.459
layer

311
00:15:34.079 –> 00:15:42.179
he’s output yes speed 20 millimeters a

312
00:15:38.459 –> 00:15:44.850
second that’s good blowing yes cut yes

313
00:15:42.179 –> 00:15:49.139
and power eighty percent that’s good

314
00:15:44.85 –> 00:15:51.059
okay now we need to make sure just be

315
00:15:49.139 –> 00:15:52.470
doubly doubly sure the last thing you

316
00:15:51.059 –> 00:15:54.660
check is that you’ve got absolute

317
00:15:52.47 –> 00:15:57.149
coordinates set down the corner here now

318
00:15:54.66 –> 00:15:59.429
we’ve set the focus up already to six

319
00:15:57.149 –> 00:16:00.530
and a half millimetres reference to this

320
00:15:59.429 –> 00:16:07.659
surface here

321
00:16:00.53 –> 00:16:07.659
[Music]

322
00:16:09.59 –> 00:16:14.060
okay so I’ve removed all the pieces and

323
00:16:12.11 –> 00:16:17.029
you can see what we’ve got there we’ve

324
00:16:14.06 –> 00:16:19.580
got a two milk gap between every single

325
00:16:17.029 –> 00:16:22.070
piece and I hope that’s gonna be enough

326
00:16:19.58 –> 00:16:24.710
of a gap to let all the smoke at the

327
00:16:22.07 –> 00:16:25.970
bottom of the job without coating the

328
00:16:24.71 –> 00:16:29.300
bottom of the job with this horrible

329
00:16:25.97 –> 00:16:30.890
brown gunk that we get by any other

330
00:16:29.3 –> 00:16:32.870
means that we can try and produce this

331
00:16:30.89 –> 00:16:34.700
puzzle right so we’ve got our fixture

332
00:16:32.87 –> 00:16:36.260
bolted back in the machine we know it’s

333
00:16:34.7 –> 00:16:38.240
the right way around because I put some

334
00:16:36.26 –> 00:16:40.130
location reference marks at the back

335
00:16:38.24 –> 00:16:42.020
corner there to make sure that we didn’t

336
00:16:40.13 –> 00:16:44.720
get in the wrong way around because

337
00:16:42.02 –> 00:16:47.390
although the jig is symmetrical the

338
00:16:44.72 –> 00:16:50.779
pattern in the puzzle is not and it only

339
00:16:47.39 –> 00:16:54.470
works this way round we’ve got our

340
00:16:50.779 –> 00:16:56.420
lovely lady that we can cut I have got

341
00:16:54.47 –> 00:17:00.650
an alternative for those that like

342
00:16:56.42 –> 00:17:03.650
aeroplanes when we engrave this it

343
00:17:00.65 –> 00:17:05.810
tended to curve this way now I would

344
00:17:03.65 –> 00:17:08.079
have liked to have put it in the jig

345
00:17:05.81 –> 00:17:10.610
that way but it meant that the middle

346
00:17:08.079 –> 00:17:13.670
would be standing up and slightly out of

347
00:17:10.61 –> 00:17:15.199
focus this has a really snug fit in here

348
00:17:13.67 –> 00:17:17.420
which is great although it’s dished

349
00:17:15.199 –> 00:17:19.400
we’ve pulled the corners down so it’s

350
00:17:17.42 –> 00:17:22.160
all back to flat again now we must

351
00:17:19.4 –> 00:17:27.800
remember to set the focus to a different

352
00:17:22.16 –> 00:17:31.510
position this time so six and a half

353
00:17:27.8 –> 00:17:31.510
lots of smoke coming out underneath

354
00:17:32.32 –> 00:17:36.460
as I mentioned right at the beginning of

355
00:17:34.24 –> 00:17:40.090
this video cutting the puzzle is the

356
00:17:36.46 –> 00:17:42.460
easy part is preparing to cut the puzzle

357
00:17:40.09 –> 00:17:45.100
that’s the difficult at this moment in

358
00:17:42.46 –> 00:17:48.159
time we’ve got all the pieces suspended

359
00:17:45.1 –> 00:17:49.570
by their ends it’s only when we start on

360
00:17:48.159 –> 00:17:52.450
the next phase which is the cross

361
00:17:49.57 –> 00:17:57.269
cutting here all of a sudden the pieces

362
00:17:52.45 –> 00:17:57.269
start releasing stress

Transcript of Making a Wooden Laser Cut Jigsaw Puzzle (Cont…)

363
00:17:58.639 –> 00:18:04.529
now we don’t at the moment seem to have

364
00:18:01.32 –> 00:18:07.409
come across any inclusions or voids

365
00:18:04.529 –> 00:18:09.299
within the material if we did they would

366
00:18:07.409 –> 00:18:11.669
have produced some probably horrible

367
00:18:09.299 –> 00:18:13.619
black marks on the surface now this

368
00:18:11.669 –> 00:18:17.249
puzzle may only be a hundred and forty

369
00:18:13.619 –> 00:18:20.539
pieces but my guess is because all the

370
00:18:17.249 –> 00:18:23.429
pieces are square there’s one piece of

371
00:18:20.539 –> 00:18:25.409
blue there is one clue that you haven’t

372
00:18:23.429 –> 00:18:27.480
got which is basically some of the

373
00:18:25.409 –> 00:18:29.340
shapes of the material the other thing

374
00:18:27.48 –> 00:18:31.739
is all this stuff is shades of brown

375
00:18:29.34 –> 00:18:34.889
which makes it very difficult to match

376
00:18:31.739 –> 00:18:37.139
up so I suspect this is going to take

377
00:18:34.889 –> 00:18:38.800
somebody quite a long time to rebuild

378
00:18:37.139 –> 00:18:43.380
this puzzle

379
00:18:38.8 –> 00:18:43.380
the piece of clear perspex underneath

380
00:18:45.54 –> 00:18:49.029
now slide the whole puzzle out

381
00:18:47.26 –> 00:18:51.099
[Music]

382
00:18:49.029 –> 00:18:54.609
and the reason I’ve slid this out onto a

383
00:18:51.099 –> 00:18:57.000
piece of a4 clear Perspex is so I can

384
00:18:54.609 –> 00:18:59.580
turn it over

385
00:18:57.0 –> 00:19:02.630
and we can have a look at the back well

386
00:18:59.58 –> 00:19:05.150
I have to say then it’s not

387
00:19:02.63 –> 00:19:07.190
entirely successful I look around each

388
00:19:05.15 –> 00:19:09.650
knob we’ve got a little pocket of gas

389
00:19:07.19 –> 00:19:11.750
which has been trapped because we

390
00:19:09.65 –> 00:19:14.480
haven’t got a clear passage for our

391
00:19:11.75 –> 00:19:16.190
smoke to exit below the cut so unless we

392
00:19:14.48 –> 00:19:20.210
can find a solution for that

393
00:19:16.19 –> 00:19:21.990
which means cutting away big chunks in

394
00:19:20.21 –> 00:19:25.030
lots of places

395
00:19:21.99 –> 00:19:28.240
[Music]

396
00:19:25.03 –> 00:19:30.430
we we probably would do just as well to

397
00:19:28.24 –> 00:19:33.640
do it on them honeycomb tighten again

398
00:19:30.43 –> 00:19:37.330
it’s cold up at the corners but not

399
00:19:33.64 –> 00:19:38.360
badly but what would do were put half a

400
00:19:37.33 –> 00:19:40.340
dozen magnets

401
00:19:38.36 –> 00:19:43.600
[Music]

402
00:19:40.34 –> 00:19:43.600
reasonably flat

403
00:19:46.62 –> 00:19:54.049
there’s not a lot of grip on Honeycomb

404
00:19:51.38 –> 00:19:56.820
no gain all we need to do is to measure

405
00:19:54.049 –> 00:19:59.000
roughly a hundred and fifty millimetres

406
00:19:56.82 –> 00:19:59.000
in

407
00:20:01.56 –> 00:20:06.120
there and that’s where we’re going to

408
00:20:03.87 –> 00:20:08.640
start now we covered the honeycomb with

409
00:20:06.12 –> 00:20:12.150
as much paper as we can to try and block

410
00:20:08.64 –> 00:20:14.400
off the airflow going down that way

411
00:20:12.15 –> 00:20:16.380
hopefully what we’re trying to do is to

412
00:20:14.4 –> 00:20:21.330
get as much air flow pulled through the

413
00:20:16.38 –> 00:20:23.690
cuts as we possibly can since the heart

414
00:20:21.33 –> 00:20:23.690
milk

415
00:20:30.52 –> 00:20:33.930
[Music]

416
00:20:35.149 –> 00:20:43.019
so from the front side that looks a

417
00:20:38.58 –> 00:20:44.490
half-decent puzzle picture let’s have a

418
00:20:43.019 –> 00:20:46.639
look see what it looks like from the

419
00:20:44.49 –> 00:20:46.639
back

420
00:20:50.0 –> 00:20:54.740
well I suppose you could always spray it

421
00:20:51.98 –> 00:20:56.419
white couldn’t you and that’s the reason

422
00:20:54.74 –> 00:20:58.370
why we started this whole project of

423
00:20:56.419 –> 00:21:00.049
saying it’s going to be very very

424
00:20:58.37 –> 00:21:03.860
difficult to get the back of these

425
00:21:00.049 –> 00:21:06.200
puzzles clean now our friend is a bit

426
00:21:03.86 –> 00:21:14.809
sad to say but I think there’s only one

427
00:21:06.2 –> 00:21:16.789
place for this and that’s in the bin now

428
00:21:14.809 –> 00:21:20.240
this was the only one that gave anything

429
00:21:16.789 –> 00:21:24.129
like half decent results and as I said

430
00:21:20.24 –> 00:21:28.460
where we had a clean run across the job

431
00:21:24.129 –> 00:21:30.919
we got virtually no marking and it was

432
00:21:28.46 –> 00:21:34.370
only when we went across this way that

433
00:21:30.919 –> 00:21:36.440
we had marks and it was mainly on the

434
00:21:34.37 –> 00:21:40.220
wall it was literally only caused by

435
00:21:36.44 –> 00:21:44.720
these tongues now what that means is you

436
00:21:40.22 –> 00:21:49.610
could possibly solve this problem by

437
00:21:44.72 –> 00:21:52.309
making two fixtures one with braces that

438
00:21:49.61 –> 00:21:55.309
run across this way and one with braces

439
00:21:52.309 –> 00:21:58.519
that run across that way so you do half

440
00:21:55.309 –> 00:22:00.350
the puzzle like this and then you do the

Transcript of Making a Wooden Laser Cut Jigsaw Puzzle (Cont…)

441
00:21:58.519 –> 00:22:03.150
other part for the puzzle in the second

442
00:22:00.35 –> 00:22:05.850
jig like that

443
00:22:03.15 –> 00:22:09.150
now if you’re that enthusiastic about

444
00:22:05.85 –> 00:22:11.490
making decent quality puzzles then there

445
00:22:09.15 –> 00:22:14.340
is a solution I’m not going to do it

446
00:22:11.49 –> 00:22:16.650
because I’ve proved half the problem has

447
00:22:14.34 –> 00:22:18.840
been resolved and I can see what the

448
00:22:16.65 –> 00:22:21.150
other half had the other half could be

449
00:22:18.84 –> 00:22:24.150
resolved but that still leaves us with

450
00:22:21.15 –> 00:22:26.130
the problem the cuts are a significant

451
00:22:24.15 –> 00:22:28.920
part of the picture

452
00:22:26.13 –> 00:22:30.840
they are predominating this may well be

453
00:22:28.92 –> 00:22:32.490
a lot less dominating if we were to do

454
00:22:30.84 –> 00:22:35.640
this with a coloured photograph because

455
00:22:32.49 –> 00:22:38.460
it would take your eye away more from

456
00:22:35.64 –> 00:22:41.640
these marks so perhaps I’ll have one

457
00:22:38.46 –> 00:22:44.400
more try at trying to create a nice

458
00:22:41.64 –> 00:22:47.160
puzzle and I think there’s a possibility

459
00:22:44.4 –> 00:22:51.000
that we might be able to do it here we

460
00:22:47.16 –> 00:22:54.210
are with a photographic print and what

461
00:22:51.0 –> 00:22:56.850
I’ve got here are two things first of

462
00:22:54.21 –> 00:23:01.610
all I’ve got some special double-sided

463
00:22:56.85 –> 00:23:05.630
and very high bond strength tape by 3m

464
00:23:01.61 –> 00:23:08.190
and you can see it’s called 3m 476 MP

465
00:23:05.63 –> 00:23:10.350
now you can buy this in sheets it’s

466
00:23:08.19 –> 00:23:14.340
pretty expensive because it’s a very

467
00:23:10.35 –> 00:23:18.240
thin film adhesive and and it’s an

468
00:23:14.34 –> 00:23:21.330
acrylic adhesive that cuts very well now

469
00:23:18.24 –> 00:23:25.410
we’ve got to apply this to the back of

470
00:23:21.33 –> 00:23:31.679
the picture and we’ll do that by peeling

471
00:23:25.41 –> 00:23:34.550
off the front clear plastic now we’ll

472
00:23:31.679 –> 00:23:34.550
fold it over like this

473
00:23:35.5 –> 00:23:43.710
so that what we can do that holds their

474
00:23:38.47 –> 00:23:48.460
end off while we fit this end nicely

475
00:23:43.71 –> 00:23:50.830
I’ve cut this already to a4 size and I

476
00:23:48.46 –> 00:23:53.350
know that it fits perfectly onto a four

477
00:23:50.83 –> 00:23:56.380
and now I should be able to just wipe

478
00:23:53.35 –> 00:24:01.120
that up there like that and stick that

Transcript of Making a Wooden Laser Cut Jigsaw Puzzle (Cont…)

479
00:23:56.38 –> 00:24:03.789
onto the top and now to make sure that I

480
00:24:01.12 –> 00:24:05.740
don’t get bubbles under it what I’m

481
00:24:03.789 –> 00:24:07.480
going to do is gradually peel this pick

482
00:24:05.74 –> 00:24:12.429
pull this piece off from underneath here

483
00:24:07.48 –> 00:24:14.260
like this while at the same time I’m

484
00:24:12.429 –> 00:24:16.720
running my finger backwards and forwards

485
00:24:14.26 –> 00:24:19.539
along here to make sure that we push all

486
00:24:16.72 –> 00:24:24.010
the air out as we go now what I’ve got

487
00:24:19.539 –> 00:24:26.409
here is a piece of it’s a piece of

488
00:24:24.01 –> 00:24:28.049
acrylic three millimetres thick this

489
00:24:26.409 –> 00:24:30.610
happens to be a piece of frosted acrylic

490
00:24:28.049 –> 00:24:34.270
now acrylic is not going to cause as

491
00:24:30.61 –> 00:24:37.030
many fumes as wood we’ve got to get the

492
00:24:34.27 –> 00:24:38.409
backing tape off of here and again we’re

493
00:24:37.03 –> 00:24:42.710
doing the same thing we’ll fold that

494
00:24:38.409 –> 00:24:46.169
over so that we can line everything up

495
00:24:42.71 –> 00:24:47.849
approximately and this time we’re going

496
00:24:46.169 –> 00:24:53.509
to use some clean kitchen towel so that

497
00:24:47.849 –> 00:24:53.509
I don’t damage the gloss on the paper

498
00:24:56.63 –> 00:25:01.620
we’re going to cover the honeycomb again

499
00:24:58.98 –> 00:25:05.010
with paper so that we get plenty of

500
00:25:01.62 –> 00:25:07.320
extraction straight through the cut and

501
00:25:05.01 –> 00:25:09.990
again we’re going to set our datum

502
00:25:07.32 –> 00:25:12.700
[Music]

503
00:25:09.99 –> 00:25:15.040
down in the middle here

504
00:25:12.7 –> 00:25:19.150
that the origin because we’re in current

505
00:25:15.04 –> 00:25:22.390
mode remember their black lines across a

506
00:25:19.15 –> 00:25:24.640
colored photograph will actually be less

507
00:25:22.39 –> 00:25:28.330
distracting than those black lines

508
00:25:24.64 –> 00:25:31.000
across a brown image now we’ve got

509
00:25:28.33 –> 00:25:33.070
fuller assist on and I’m trying to

510
00:25:31.0 –> 00:25:36.280
extract as much air as I can out the

511
00:25:33.07 –> 00:25:39.460
back because it’s absolutely essential

512
00:25:36.28 –> 00:25:42.610
that we don’t get any white debris up on

513
00:25:39.46 –> 00:25:45.570
top of our job all the smoke must go out

514
00:25:42.61 –> 00:25:45.570
the back of the job

515
00:25:50.86 –> 00:25:56.940
[Music]

516
00:25:52.7 –> 00:26:01.190
now comes the tricky bit getting it off

517
00:25:56.94 –> 00:26:01.190
the table

518
00:26:02.8 –> 00:26:08.819
[Music]

519
00:26:09.96 –> 00:26:17.740
look at the madness on the top there

520
00:26:13.41 –> 00:26:20.110
oh my goodness me the dust has come up

521
00:26:17.74 –> 00:26:26.540
but it does wipe off easily

522
00:26:20.11 –> 00:26:26.540
[Music]

523
00:26:28.67 –> 00:26:33.090
and surprisingly now if it has not

524
00:26:31.18 –> 00:26:40.820
damaged the picture

525
00:26:33.09 –> 00:26:40.820
[Music]

526
00:26:40.94 –> 00:26:44.760
just keep wiping it until the tissue

527
00:26:42.89 –> 00:26:47.490
goes clean

528
00:26:44.76 –> 00:26:50.610
okay so we’ve juggled it now on to our

529
00:26:47.49 –> 00:26:52.390
piece of paper let’s see what it’s like

530
00:26:50.61 –> 00:27:07.690
on the back Sheree

531
00:26:52.39 –> 00:27:11.450
[Music]

532
00:27:07.69 –> 00:27:14.030
well I would say that that’s almost

533
00:27:11.45 –> 00:27:15.620
presentable on the back there well in

534
00:27:14.03 –> 00:27:17.390
this session I hope that I’ve steered

535
00:27:15.62 –> 00:27:22.340
you away from all the possible pitfalls

536
00:27:17.39 –> 00:27:24.110
of making a wooden puzzle now a wooden

537
00:27:22.34 –> 00:27:26.630
puzzle is something that really is

538
00:27:24.11 –> 00:27:28.760
reserved for a clean machine like a

539
00:27:26.63 –> 00:27:31.760
jigsaw which is why it’s called a jigsaw

540
00:27:28.76 –> 00:27:33.559
puzzle laser cutting is not a very good

541
00:27:31.76 –> 00:27:36.410
process for working with wood or

542
00:27:33.559 –> 00:27:38.870
cardboard because we produce far too

543
00:27:36.41 –> 00:27:42.010
many fumes which will condense and

544
00:27:38.87 –> 00:27:44.770
damage your pieces

545
00:27:42.01 –> 00:27:47.410
what we have finally shown you is the

546
00:27:44.77 –> 00:27:49.660
way in which you can succeed by

547
00:27:47.41 –> 00:27:52.780
producing a really nice contrasting

548
00:27:49.66 –> 00:27:55.860
colour picture which takes your eye away

549
00:27:52.78 –> 00:27:58.510
from the black lines that are on here

550
00:27:55.86 –> 00:28:00.100
you have to do it from the front so you

551
00:27:58.51 –> 00:28:02.860
need to make sure that you get your

00:28:00.1 –> 00:28:05.010
parameters set up well although we have

553
00:28:02.86 –> 00:28:08.380
got some black marks on the back here

554
00:28:05.01 –> 00:28:12.000
into a few places those black marks

555
00:28:08.38 –> 00:28:15.040
would not show at all if you change this

556
00:28:12.0 –> 00:28:18.070
material from either clear or frosted

557
00:28:15.04 –> 00:28:21.700
acrylic as I’ve got it there into a

558
00:28:18.07 –> 00:28:24.640
satin finished black now put the satin

559
00:28:21.7 –> 00:28:27.010
finish facedown on the honeycomb table

560
00:28:24.64 –> 00:28:30.360
and you will probably hide any marks

561
00:28:27.01 –> 00:28:32.530
that happened to be on the back here so

562
00:28:30.36 –> 00:28:35.050
now you have the secret to making

563
00:28:32.53 –> 00:28:39.190
personalized puzzles and I will pass

564
00:28:35.05 –> 00:28:40.870
this puzzle program on to think later so

565
00:28:39.19 –> 00:28:44.170
that you can download it for yourself

566
00:28:40.87 –> 00:28:45.660
well thanks again for your time and I’ll

567
00:28:44.17 –> 00:28:50.160
see you in another session

568
00:28:45.66 –> 00:28:50.160
