TRASNCRIPT:

1
00:00:00,030 –> 00:00:04,799
hey folks Atari here I’ve been playing

2
00:00:02,790 –> 00:00:05,580
around with this Robo 3d printer for a

3
00:00:04,799 –> 00:00:07,379
while now

4
00:00:05,580 –> 00:00:10,110
and I think I’ve got the hang of it

5
00:00:07,379 –> 00:00:12,660
finally the thing about 3d printing is

6
00:00:10,110 –> 00:00:14,670
it’s very much a hacker minded hobby

7
00:00:12,660 –> 00:00:17,850
there’s a lot of trial and error

8
00:00:14,670 –> 00:00:20,369
involved in the process and most

9
00:00:17,850 –> 00:00:22,710
consumer grade printers do lack a lot of

10
00:00:20,369 –> 00:00:24,960
the out-of-the-box features got some of

11
00:00:22,710 –> 00:00:27,539
the higher-end printers include which

12
00:00:24,960 –> 00:00:30,300
leads people like me to go ahead and

13
00:00:27,539 –> 00:00:32,750
build their own upgrades what I’ve done

14
00:00:30,300 –> 00:00:36,090
here is I’ve installed a Raspberry Pi

15
00:00:32,750 –> 00:00:39,420
with the octoprint software to make a

16
00:00:36,090 –> 00:00:42,719
self-contained Wi-Fi printer and then I

17
00:00:39,420 –> 00:00:45,809
installed a webcam to capture time-lapse

18
00:00:42,719 –> 00:00:48,510
videos of the print process as well as

19
00:00:45,809 –> 00:00:51,449
some LED lighting for better video

20
00:00:48,510 –> 00:00:53,390
capturing and then I’ve you know kind of

21
00:00:51,449 –> 00:00:57,390
rejiggered the cabling and the filament

22
00:00:53,390 –> 00:00:58,559
feeds so that they’re going to move a

23
00:00:57,390 –> 00:01:01,949
little bit better and they don’t be

24
00:00:58,559 –> 00:01:03,629
caught up in may in the works inside it

25
00:01:01,949 –> 00:01:08,280
just makes for a whole lot better

26
00:01:03,629 –> 00:01:11,310
experience so this video is going to

27
00:01:08,280 –> 00:01:16,350
walk you through the process that I use

28
00:01:11,310 –> 00:01:19,320
to install these physical upgrades but I

29
00:01:16,350 –> 00:01:21,659
will have a link in the doobly-doo and

30
00:01:19,320 –> 00:01:26,150
probably up here in the corner a link to

31
00:01:21,659 –> 00:01:30,600
a full how-to article about about

32
00:01:26,150 –> 00:01:33,479
installing and setting up octoprint on

33
00:01:30,600 –> 00:01:35,100
the Raspberry Pi or octopi as its called

34
00:01:33,479 –> 00:01:38,220
I will put a link to that I’ll have a

35
00:01:35,100 –> 00:01:40,680
full write-up on airborne surfer comm so

36
00:01:38,220 –> 00:01:42,720
you can follow that guide there but

37
00:01:40,680 –> 00:01:46,380
again this is going to walk through the

38
00:01:42,720 –> 00:01:48,509
physical installation and with that with

39
00:01:46,380 –> 00:01:50,579
the write-up on the software that should

40
00:01:48,509 –> 00:01:52,680
get you through a pretty much down the

41
00:01:50,579 –> 00:01:54,840
gist of it the first thing I’m going to

42
00:01:52,680 –> 00:01:56,939
fix is the zip tie loop for the cable

43
00:01:54,840 –> 00:01:58,770
loom having a zip tie here has been

44
00:01:56,939 –> 00:02:01,950
holding the Loom a little too rigidly

45
00:01:58,770 –> 00:02:03,930
and has led to a few failed prints I’ve

46
00:02:01,950 –> 00:02:06,210
already cut the zip ties since removing

47
00:02:03,930 –> 00:02:08,640
the hood and now I need to replace the

48
00:02:06,210 –> 00:02:10,500
mounting point for the zip tire I found

49
00:02:08,640 –> 00:02:13,140
a suitable two piece cable loop on

50
00:02:10,500 –> 00:02:15,480
Thingiverse that holds the Loom in

51
00:02:13,140 –> 00:02:18,240
face while being loose enough to allow

52
00:02:15,480 –> 00:02:20,000
some play in the tension remove the two

53
00:02:18,240 –> 00:02:23,459
screws holding the loop mount in place

54
00:02:20,000 –> 00:02:25,740
then replace it with the base of the

55
00:02:23,459 –> 00:02:29,580
two-piece print hang on to the second

56
00:02:25,740 –> 00:02:31,709
piece for later next thing to do is

57
00:02:29,580 –> 00:02:34,500
install some lighting I picked up the

58
00:02:31,709 –> 00:02:37,680
self-adhesive USB powered LED strip from

59
00:02:34,500 –> 00:02:40,530
Amazon and ran it along the interior of

60
00:02:37,680 –> 00:02:42,630
the hood be sure to start with the USB

61
00:02:40,530 –> 00:02:44,790
plug on the slide with the cable well

62
00:02:42,630 –> 00:02:48,239
this is the same side that the loop

63
00:02:44,790 –> 00:02:51,120
mount is installed now before we put the

64
00:02:48,239 –> 00:02:53,459
hood back on go ahead and unplug the USB

65
00:02:51,120 –> 00:02:56,820
cable and the power cable from the

66
00:02:53,459 –> 00:02:59,130
printer place the hood back onto the

67
00:02:56,820 –> 00:03:02,130
base of the printer with the cable loop

68
00:02:59,130 –> 00:03:04,350
on the same side as the well make sure

69
00:03:02,130 –> 00:03:07,170
all the wiring is tucked inside the hood

70
00:03:04,350 –> 00:03:10,170
before pressing down to properly align

71
00:03:07,170 –> 00:03:14,550
the screw holes then screw the hood

72
00:03:10,170 –> 00:03:17,489
securely in place now gently lift the

73
00:03:14,550 –> 00:03:19,440
printer and set it on its side make sure

74
00:03:17,489 –> 00:03:21,810
to hold on to the print cartridge and

75
00:03:19,440 –> 00:03:24,870
abed as they’re likely to slide around

76
00:03:21,810 –> 00:03:26,790
to install the Raspberry Pi we’re going

77
00:03:24,870 –> 00:03:29,190
to need to siphon some electricity from

78
00:03:26,790 –> 00:03:32,340
the printers power supply specifically

79
00:03:29,190 –> 00:03:40,590
from the AC input coming from the switch

80
00:03:32,340 –> 00:03:43,590
on the back of the unit the power supply

81
00:03:40,590 –> 00:03:44,610
on a robo 3d printer is a tough zombie

82
00:03:43,590 –> 00:03:46,769
to remove

83
00:03:44,610 –> 00:03:50,040
there aren’t any screws or anything it’s

84
00:03:46,769 –> 00:03:53,430
just held in the friction very tightly

85
00:03:50,040 –> 00:03:56,190
as you can see taking quite a bit of

86
00:03:53,430 –> 00:03:58,950
effort to remove I found that shifting

87
00:03:56,190 –> 00:04:01,380
it down at an angle back and forth will

88
00:03:58,950 –> 00:04:04,290
garner the quickest results but your

89
00:04:01,380 –> 00:04:06,810
mileage may vary so here are the

90
00:04:04,290 –> 00:04:09,049
terminals these four go into the Arduino

91
00:04:06,810 –> 00:04:13,790
board that controls the printer and

92
00:04:09,049 –> 00:04:19,289
these three are for the AC what dish

93
00:04:13,790 –> 00:04:20,489
blue brown green and yellow OnLive just

94
00:04:19,289 –> 00:04:24,639
get get somebody killed

95
00:04:20,489 –> 00:04:27,039
you see standards exist for a reason

96
00:04:24,639 –> 00:04:29,889
well they exist for many reasons but one

97
00:04:27,039 –> 00:04:33,099
of them is safety international standard

98
00:04:29,889 –> 00:04:35,289
wiring colors are such so that one does

99
00:04:33,099 –> 00:04:37,710
not accidentally connect the wrong

100
00:04:35,289 –> 00:04:41,439
conduct to do the wrong terminal or

101
00:04:37,710 –> 00:04:47,740
worse touch the wrong live conductor

102
00:04:41,439 –> 00:04:50,199
this is wrong this is it’s good right

103
00:04:47,740 –> 00:04:57,370
I mean bed at least the goddamn

104
00:04:50,199 –> 00:04:59,770
terminals are clearly marked anyway

105
00:04:57,370 –> 00:05:02,919
we’re going to need to tap into these

106
00:04:59,770 –> 00:05:05,139
leads to direct power to a standard 110

107
00:05:02,919 –> 00:05:07,180
volt outlet so that we can use an

108
00:05:05,139 –> 00:05:08,379
off-the-shelf power converter to power

109
00:05:07,180 –> 00:05:10,870
the Raspberry Pi

110
00:05:08,379 –> 00:05:14,169
we’ll start by loosening the terminal

111
00:05:10,870 –> 00:05:16,629
screws and removing the leads I picked

112
00:05:14,169 –> 00:05:19,210
up this outlet saver at micro Center for

113
00:05:16,629 –> 00:05:21,310
a couple of dollars essentially it’s a

114
00:05:19,210 –> 00:05:23,919
10 inch long grounded extension cord

115
00:05:21,310 –> 00:05:26,770
take a pair of scissors and cut off the

116
00:05:23,919 –> 00:05:29,589
plug-in then strip away the outer casing

117
00:05:26,770 –> 00:05:32,740
leaving just the outlet end and the

118
00:05:29,589 –> 00:05:35,949
exposed inner wiring at least these

119
00:05:32,740 –> 00:05:37,779
wires are the proper colors so now we

120
00:05:35,949 –> 00:05:40,569
just need to strip the end of the

121
00:05:37,779 –> 00:05:43,330
insulation off of each of the wires so

122
00:05:40,569 –> 00:05:45,940
we can hook them up to the terminal now

123
00:05:43,330 –> 00:05:48,969
remember kids ground is green like grass

124
00:05:45,940 –> 00:05:51,960
on the ground white is neutral because

125
00:05:48,969 –> 00:05:55,719
it’s the neutral color and black is live

126
00:05:51,960 –> 00:05:58,060
because black lives matter anyway

127
00:05:55,719 –> 00:06:01,270
so we reinsert the leads from the switch

128
00:05:58,060 –> 00:06:04,240
into the proper terminal then insert the

129
00:06:01,270 –> 00:06:06,810
new leads from the extension cord into

130
00:06:04,240 –> 00:06:10,599
the appropriate terminals as well and

131
00:06:06,810 –> 00:06:13,270
tighten the retaining screw then simply

132
00:06:10,599 –> 00:06:19,629
reposition the power supply back inside

133
00:06:13,270 –> 00:06:21,789
its retainer with a good shove now we’re

134
00:06:19,629 –> 00:06:23,770
going to need to run a USB cable to

135
00:06:21,789 –> 00:06:26,259
connect the Arduino to the Raspberry Pi

136
00:06:23,770 –> 00:06:28,900
and because the Arduino is mounted so

137
00:06:26,259 –> 00:06:31,330
close to the edge of the base we’re

138
00:06:28,900 –> 00:06:33,789
going to use this right angle USB cable

139
00:06:31,330 –> 00:06:36,279
to make the connection now even with the

140
00:06:33,789 –> 00:06:38,409
low profile of the right angle cable

141
00:06:36,279 –> 00:06:41,469
though we’re going to need to

142
00:06:38,409 –> 00:06:43,569
move the Arduino to plug in the cable so

143
00:06:41,469 –> 00:06:46,179
just remove these three mounting screws

144
00:06:43,569 –> 00:06:48,669
from the Arduino and carefully plug in

145
00:06:46,179 –> 00:06:51,309
the USB cable you can use the existing

146
00:06:48,669 –> 00:06:54,219
wires to hold the new USB cable in place

147
00:06:51,309 –> 00:06:57,009
just be careful not to pull any of the

148
00:06:54,219 –> 00:06:58,959
wires from the Arduino screw the Arduino

149
00:06:57,009 –> 00:06:59,619
back into place and you’re done with

150
00:06:58,959 –> 00:07:03,279
step 2

151
00:06:59,619 –> 00:07:05,769
I found the simple mouth for a Raspberry

152
00:07:03,279 –> 00:07:08,379
Pi on Thingiverse but I also printed if

153
00:07:05,769 –> 00:07:10,959
you get the hole size right you can use

154
00:07:08,379 –> 00:07:12,610
screws to mount the pie in place but I’m

155
00:07:10,959 –> 00:07:15,339
just going to use glue as it’s a little

156
00:07:12,610 –> 00:07:17,439
easier than drilling out the hole apply

157
00:07:15,339 –> 00:07:20,349
the glue to the mount and press the

158
00:07:17,439 –> 00:07:22,419
Raspberry Pi board into place some glue

159
00:07:20,349 –> 00:07:24,279
should come through the holes in the pie

160
00:07:22,419 –> 00:07:26,409
and mushroom over to provide a pretty

161
00:07:24,279 –> 00:07:29,919
good hole clamp some parts together

162
00:07:26,409 –> 00:07:32,110
until the glue sets apply glue along the

163
00:07:29,919 –> 00:07:35,050
perimeter of the mouth and press it into

164
00:07:32,110 –> 00:07:36,669
place on the bottom of the printer make

165
00:07:35,050 –> 00:07:39,779
sure to hold it tightly against the base

166
00:07:36,669 –> 00:07:42,579
of the printer until they do the sex

167
00:07:39,779 –> 00:07:45,789
finally plug the printer into one of the

168
00:07:42,579 –> 00:07:48,279
USB ports on the pie plug one end of a

169
00:07:45,789 –> 00:07:50,529
USB to micro USB cable into the power

170
00:07:48,279 –> 00:07:52,659
port on the Raspberry Pi and the other

171
00:07:50,529 –> 00:07:54,999
end into a wall wart power converter I

172
00:07:52,659 –> 00:07:57,669
think this one up at Tashi station for

173
00:07:54,999 –> 00:07:59,860
about 5 imperial credits just make sure

174
00:07:57,669 –> 00:08:02,709
it’s rated for at least 5 volts and 1

175
00:07:59,860 –> 00:08:04,689
ampere plug your power converter into

176
00:08:02,709 –> 00:08:07,239
your hacked up power outlet from earlier

177
00:08:04,689 –> 00:08:10,839
and now your pie is powered on by the

178
00:08:07,239 –> 00:08:12,759
main switch on the printer again you can

179
00:08:10,839 –> 00:08:16,719
use the existing wiring to hold your new

180
00:08:12,759 –> 00:08:18,579
wiring in place I picked up a short USB

181
00:08:16,719 –> 00:08:20,259
extension cable to connect the lighting

182
00:08:18,579 –> 00:08:24,369
to the PI as well so I just need to

183
00:08:20,259 –> 00:08:26,259
connect that the last USB connection is

184
00:08:24,369 –> 00:08:28,479
made for the webcam which will record

185
00:08:26,259 –> 00:08:30,699
our time-lapse videos for this i’ll

186
00:08:28,479 –> 00:08:32,589
thread the USB cable from the front of

187
00:08:30,699 –> 00:08:34,659
the printer through the cable well to

188
00:08:32,589 –> 00:08:37,350
the underside of the printer and connect

189
00:08:34,659 –> 00:08:40,120
it to the Raspberry Pi

190
00:08:37,350 –> 00:08:41,950
before setting the printer up light go

191
00:08:40,120 –> 00:08:44,500
ahead and insert the cable loom in place

192
00:08:41,950 –> 00:08:46,690
inside the loop installed earlier and

193
00:08:44,500 –> 00:08:51,220
enclose it with the locking piece then

194
00:08:46,690 –> 00:08:52,900
carefully write the printer this is a

195
00:08:51,220 –> 00:08:54,670
widget that I designed myself and

196
00:08:52,900 –> 00:08:56,980
Tinkercad and I’ll put a link to it in

197
00:08:54,670 –> 00:08:58,900
the doobly-do what it does is it clamps

198
00:08:56,980 –> 00:09:01,270
onto the edge of the print bed and

199
00:08:58,900 –> 00:09:03,970
allows you to mount a clamp style webcam

200
00:09:01,270 –> 00:09:06,130
level with the print bed so you can

201
00:09:03,970 –> 00:09:09,490
capture time-lapse video that stabilize

202
00:09:06,130 –> 00:09:11,860
to the y-axis stabilizing one axis is

203
00:09:09,490 –> 00:09:13,480
nice because otherwise motion gets

204
00:09:11,860 –> 00:09:17,410
really messy and you can’t really see

205
00:09:13,480 –> 00:09:19,180
much detail in your printing lastly

206
00:09:17,410 –> 00:09:20,800
we’re going to turn the printer around

207
00:09:19,180 –> 00:09:23,410
to the back so I can install the new

208
00:09:20,800 –> 00:09:25,180
spool holder that I printed this is a

209
00:09:23,410 –> 00:09:27,940
replacement for the stock holder that

210
00:09:25,180 –> 00:09:29,590
hangs off the side of the hood this one

211
00:09:27,940 –> 00:09:31,720
keeps the footprint of the printer a

212
00:09:29,590 –> 00:09:33,700
little smaller and keeps the filament

213
00:09:31,720 –> 00:09:35,620
closer to the center axis of the printer

214
00:09:33,700 –> 00:09:38,470
which helps keep the feed steady

215
00:09:35,620 –> 00:09:40,060
preventing jams and tangles and it just

216
00:09:38,470 –> 00:09:43,290
grips onto the side of the hood and

217
00:09:40,060 –> 00:09:43,290
slides down to lock in place

218
00:09:43,950 –> 00:09:48,580
now if you’ll install these upgrades as

219
00:09:46,690 –> 00:09:50,530
soon as possible after setting up your

220
00:09:48,580 –> 00:09:51,730
logo through the printer you’ll find

221
00:09:50,530 –> 00:09:55,030
that you’re going to get a much better

222
00:09:51,730 –> 00:09:57,370
and much more consistent quality in your

223
00:09:55,030 –> 00:10:01,540
prints and you’ll have a lot fewer

224
00:09:57,370 –> 00:10:03,250
headaches along the way so anyway thanks

225
00:10:01,540 –> 00:10:05,320
