BigTreeTech Octopus v1.1 Klipper Install & Printer Configuration — Transcript

Full transcript

1. 0:00right at this point i've got everything
2. 0:01wired up and now i'm ready to configure
3. 0:03clipper
4. 0:03and just kind of get everything
5. 0:05connected with the raspberry pi
6. 0:07okay i've actually found using the voron
7. 0:09instructions very helpful for installing
8. 0:11clipper and mainsail
9. 0:12so i'm just going to go ahead and follow
10. 0:14that for at least for
11. 0:16getting uh you know clipper installed on
12. 0:18my raspberry pi
13. 0:19there are several different front ends
14. 0:21that you can run clipper with
15. 0:22and i prefer mainsail i think it's
16. 0:24really easy to use
17. 0:26fluid is also very similar and then if
18. 0:28you're more of an octoprint kind of
19. 0:29person
20. 0:30uh you know you can use that too but i
21. 0:32find that it's pretty heavy weight
22. 0:34and way more than what you would want
23. 0:36just to run clipper
24. 0:37another benefit to using mainsail or
25. 0:39fluid is that you can run it off
26. 0:40something like a pi
27. 0:42zero because it's so lightweight but i'm
28. 0:44actually using a
29. 0:45raspberry pi 3 for mine okay the first
30. 0:47step is to be
31. 0:48to download mainsail os so i'm going to
32. 0:51go ahead and grab
33. 0:52the latest zip here in order to flash
34. 0:54the image that you just downloaded
35. 0:56you're going to want to
36. 0:57use this baleno etcher and just download
37. 0:59that it's available on either
38. 1:01mac os or for windows and now i'm going
39. 1:03to flash from file
40. 1:05the image that i just downloaded and
41. 1:07unzipped
42. 1:10and then i go ahead and hit flash after
43. 1:12you get done with the etching
44. 1:14uh you have to go in here and update
45. 1:16your
46. 1:17your wpa supplicant file and what you're
47. 1:20going to put in here is your network
48. 1:22ssid that's case sensitive so make sure
49. 1:24you put it in
50. 1:26exactly how you spell it
51. 1:30okay my next step is to power up the
52. 1:32raspberry pi
53. 1:33with the flashed card in it for clipper
54. 1:36and mainsail i've got my power cable
55. 1:39here
56. 1:40now if i wanted to i could wire my pi to
57. 1:43my board but i think for now
58. 1:44i'm just going to power it this way uh
59. 1:47after i get everything flash and a
60. 1:48firmware file generated
61. 1:50then i'm going to take an sd card and
62. 1:52i'm going to have to flash
63. 1:54it here and i'll go through that step as
64. 1:56well okay so i'm going to use a program
65. 1:58called putty
66. 1:59to connect to mainsail
67. 2:02and it's going to give me the security
68. 2:04error just go ahead and hit yes
69. 2:06and for password you're going to enter
70. 2:08raspberry
71. 2:09and before we're going to do much with
72. 2:10the clipper menu config we want to go
73. 2:12ahead and
74. 2:13make sure clipper is updated so the
75. 2:15first thing we're going to do
76. 2:17is run a few commands one is to change
77. 2:19the directories to clipper if you're not
78. 2:21already there
79. 2:22then you're going to run sudo
80. 2:25system ctl
81. 2:31stop clipper
82. 2:35that's going to make sure that the
83. 2:36clipper is not running
84. 2:38and then we're going to go get pull this
85. 2:41is going to pull the latest down
86. 2:45and then we're going to go we're going
87. 2:46to go ahead and start it up
88. 2:50okay now we're ready to run to do the
89. 2:52make menu config command which i have
90. 2:54typed there
91. 2:57now you should have all the options that
92. 2:59you need so i've already kind of gone
93. 3:01through this but
94. 3:03you're going to you're going to hit
95. 3:04enter or space and then pick
96. 3:06stm32 you're going to make sure you pick
97. 3:09the stm32f446
98. 3:13bootloader you want 32 kib boot loader
99. 3:17um clock reference you want 12 megahertz
100. 3:19crystal
101. 3:21communication for interface this depends
102. 3:23on how you're going to be running it in
103. 3:25my case it'll be over usb
104. 3:27but if you're going to use one of the
105. 3:29uart pins you can do that as well
106. 3:32um and that's pretty much what all you
107. 3:35need
108. 3:35so once you're done you're going to hit
109. 3:37quit and then if you had to save it you
110. 3:39would hit yes
111. 3:41and in order to compile everything hit
112. 3:43make clean
113. 3:44and then hit type in make and hit enter
114. 3:48and everything should start compiling
115. 3:52and the very last step it should say
116. 3:53creating hex file out clipper bin
117. 3:56as you can see at the very bottom here
118. 3:58and we're just going to go ahead and
119. 3:59confirm it's there by changing directory
120. 4:01into the out
121. 4:02and then looking to see for our clipper
122. 4:04min file now the next thing we're going
123. 4:06to need to do is copy that bin file
124. 4:08to an sd card that we can then insert
125. 4:10into the octopus board
126. 4:12i'm going to use a program called winscp
127. 4:16so i'm going to go ahead and load that
128. 4:17and then i'm going to type in my
129. 4:19hostname
130. 4:20which is mainsail os
131. 4:24and then my username is pi password
132. 4:28is raspberry
133. 4:32and then i should be able to go ahead
134. 4:33and hit log in
135. 4:35i can pick any just leave it on sftp
136. 4:40um just go ahead and say add
137. 4:44and now you should be able to browse to
138. 4:46the clipper directory
139. 4:48to the out and then download clipper.bin
140. 4:53i'm just going to go ahead and click
141. 4:54download
142. 4:56and it doesn't really matter where you
143. 4:59download it
144. 5:00but i will go ahead and put it in my
145. 5:02downloads folder
146. 5:07um so overwrite the local file
147. 5:10yeah why not okay so i went ahead and
148. 5:13downloaded it
149. 5:14you're going to need to rename it to
150. 5:16firmware.bin
151. 5:19because that's what the octopus board is
152. 5:20going to read
153. 5:22so once you rename that you can then
154. 5:24copy it over to your
155. 5:25sd card
156. 5:29okay so i went ahead and copied it over
157. 5:31and i renamed it to firmware.bin once i
158. 5:34got to my sd card
159. 5:36so the next step is simply um you're
160. 5:39going to
161. 5:39unload your or eject your card from your
162. 5:42computer
163. 5:43and once you pull out your card which i
164. 5:46have here
165. 5:47you're going to take this and put it in
166. 5:48the octopus board okay so i'm over here
167. 5:50at the octopus board now
168. 5:52i'm going to go ahead and insert that sd
169. 5:53card that i just copied the firmware bin
170. 5:55file to
171. 5:56so that should be good as you can see
172. 5:58i've got the card in
173. 5:59you can either power it up with your
174. 6:00power supply
175. 6:02or you can power it up with your
176. 6:04raspberry pi which is how i'm going to
177. 6:06do it
178. 6:07so i'm just going to take my raspberry
179. 6:10pi
180. 6:10cable and plug it in
181. 6:14so i went ahead and plug that in now
182. 6:17and it should be applying that firmware
183. 6:20so this is one way that you know how
184. 6:21your firmware been was successful
185. 6:23is when you run the ls command the lsdev
186. 6:26serial by id
187. 6:27right here you should get something that
188. 6:29looks like this with a very specific
189. 6:31uh you know identifier here um and it
190. 6:35should
191. 6:35read your chip that you just configured
192. 6:38so mine looks good
193. 6:39um now now that was probably the easy
194. 6:41part now we got to do the
195. 6:42printer.config file what you can verify
196. 6:45it is by removing your
197. 6:47um your your sd card from the
198. 6:50octopus and checking for the presence of
199. 6:52this firmware.cur file now i'm going to
200. 6:54go ahead and suggest
201. 6:56uh you know starting with this voron2
202. 6:58config file even though
203. 7:00i'm not running a boron there's probably
204. 7:01a lot of similarities here with how i
205. 7:03have things set up
206. 7:05so i'm going to go ahead and use this as
207. 7:06my starting point something that you're
208. 7:08definitely going to want to look at
209. 7:10as you go through this configuration is
210. 7:12the pin out for the big treetech octopus
211. 7:14board
212. 7:15and you can find that in the github
213. 7:16location in their documentation folder
214. 7:20okay here you can see i've highlighted
215. 7:22the diagram so you can
216. 7:23get an idea of how this works so look at
217. 7:26the hot end pins
218. 7:27and then you can see it says he 0 which
219. 7:29is where you physically connect it
220. 7:31where the air is pointing and then
221. 7:32there's another arrow pointing to the
222. 7:34right
223. 7:35and you can see that it's pa2 is the
224. 7:37actual pin you're going to use okay one
225. 7:39of the first things you're going to need
226. 7:40to do
227. 7:41is change whatever line they have in
228. 7:43there
229. 7:44with whatever line you have when you did
230. 7:46your ls command
231. 7:48so if you don't have a line that looks
232. 7:49like this it probably means your
233. 7:51firmware is not applied properly here
234. 7:54you can see a close-up of my clipper
235. 7:56printer configuration file
236. 7:58and the first thing that i need to do is
237. 7:59add the printer section and under there
238. 8:01it has
239. 8:02kinematics core xy which is needed for
240. 8:04my core xy build
241. 8:06and then i just change the velocity and
242. 8:08acceleration
243. 8:10here you can see that i'm configuring
244. 8:11the xy motors
245. 8:14and i need to make sure that the pin out
246. 8:15matches
247. 8:17which in this case it's motor zero
248. 8:21something else that i'll point out is
249. 8:22that i'm also marking the end stop pin
250. 8:24and setting that to
251. 8:26pg9 as you can see there so that's uh
252. 8:29the proper pin number for the x endstop
253. 8:31and i had to do the same thing
254. 8:32for the y as well here you can see i've
255. 8:36done something very similar for the y
256. 8:39and i've confirmed that the pins are
257. 8:41correct based on the motors that i have
258. 8:43it connected to
259. 8:44so in this case it's motor one you'll
260. 8:46also see here that i've
261. 8:48changed the full steps per rotation
262. 8:51setting to 400 because i'm using
263. 8:530.9 degree stepper motors instead of the
264. 8:56standard 1.8
265. 8:57if you're using 1.8 the default would be
266. 9:00200
267. 9:00and you don't even need to change it so
268. 9:03something else that i didn't mention on
269. 9:05the previous screen was the position max
270. 9:08so my cube is a 300 by 300 by 400
271. 9:11so i went ahead and filled in 300 both
272. 9:14here and
273. 9:15in the past setting on the x as well
274. 9:20and here are the settings for my z
275. 9:21stepper as you can see i
276. 9:23once again confirmed the motor pin and i
277. 9:26i really did look at the uh
278. 9:28pin out in order to confirm this the
279. 9:30other thing you'll notice is that
280. 9:32i i went ahead and commented out where
281. 9:34it says zero stepper front left
282. 9:36so there's actually two motor ports and
283. 9:38i'm running a dual z so that works out
284. 9:40really well i just plug the plug one
285. 9:42into the one
286. 9:43and one into the other it doesn't matter
287. 9:45which side is which the other thing that
288. 9:47i put on here is a position max of about
289. 9:49385
290. 9:50and i did set the position endstop to
291. 9:530.05
292. 9:54that gives me a little bit of lift above
293. 9:56the z it's like an offset
294. 9:58and under each of the stepper sections
295. 10:00you're going to see this tmc2209
296. 10:03so what i did if you remember in the
297. 10:04previous video i copied down my settings
298. 10:06for motor current
299. 10:08so in in my case it was uh 1000 for z so
300. 10:12in clipper it's a 1. so i just went
301. 10:14ahead and filled that out as well
302. 10:16and now we're in the extruder section
303. 10:18and here i once again confirmed
304. 10:20and i'm using e0 which is on my motor 3.
305. 10:23so you can see all the pin settings
306. 10:26there
307. 10:26one other thing that you see here is the
308. 10:28rotation distance and i had to calibrate
309. 10:30my extruder and there's a formula
310. 10:33for coming up with that it's basically
311. 10:34running 120 millimeter
312. 10:36filament test through the extruder and
313. 10:39you know you go you do that a few times
314. 10:41and you eventually come to a number
315. 10:43so for me that was 7.2 and i'll put a
316. 10:45link in the description on how to do
317. 10:46that
318. 10:48the other thing that you'll notice here
319. 10:49is that i've got a heater pin setting
320. 10:50which is where my thermistor is plugged
321. 10:52into
322. 10:53once again on the pin out and that's pa2
323. 10:56and then you also see
324. 10:58the sensor pin and the sensor type and
325. 11:00those are important to get correct
326. 11:02and there are some different settings
327. 11:04that you can look up to see what
328. 11:06values you should use for sensor type
329. 11:08and there's also a
330. 11:10tmc2209 section for the extruder
331. 11:12and here i set my run current and hold
332. 11:15current
333. 11:16set them the same which is uh so in
334. 11:18marlin it was 1100
335. 11:20and here it's going to be 1.1 and that
336. 11:22seems to be
337. 11:23a good value for my particular hymera
338. 11:25setup it's a little high
339. 11:26but it does work really well okay and
340. 11:29here you can see i've got the heater bed
341. 11:31uh settings and basically the first very
342. 11:34first thing there is the pin
343. 11:35that's going to power the bed so ssr pin
344. 11:38bed out
345. 11:39and then the sensor type which is the
346. 11:42thermistor
347. 11:43and then the sensor pin which is uh the
348. 11:45pin thermistor is going to use
349. 11:47something else i'll note here is the max
350. 11:49power if you don't want your bed to
351. 11:51just go full power you can change this
352. 11:53to a value less than one
353. 11:55um in my case i've got a fairly low
354. 11:57wattage ac bed so one is fine
355. 12:00the reason that you might want to change
356. 12:01that is if you have a higher wattage bed
357. 12:04in some cases if you heat the bed too
358. 12:06fast it can talk to the bed or basically
359. 12:08change the
360. 12:09you know the the flatness of it okay and
361. 12:12now we're in the fan control section of
362. 12:14the file
363. 12:15and here you can see i've got two fans
364. 12:17to find the first one is the print
365. 12:19cooling fan
366. 12:20and that's once again confirming with
367. 12:21the pin out pe5 to where i have it
368. 12:23plugged in
369. 12:24and then i'm making sure that it's set
370. 12:26to max power and i'm just using a
371. 12:28default settings here for the kickstart
372. 12:31and then i've also got my hot end fan
373. 12:33below that
374. 12:34and i want that only to turn on when the
375. 12:37temperature of the
376. 12:39thermistor is 50 c or above okay this
377. 12:42last section here
378. 12:43is the safe z home and what you're going
379. 12:45to see here is the home x y position
380. 12:47which is important
381. 12:49and after that you're going to see a
382. 12:51speed and a z-hop
383. 12:52so when it does do a home it's going to
384. 12:54use that speed and it'll hop
385. 12:56every time you do a home for any axis
386. 13:00x or y and the very last thing you see
387. 13:03on the screen
388. 13:03is the input shaper and please don't put
389. 13:06that in your
390. 13:07file if you're watching that is
391. 13:08something that you want to calibrate in
392. 13:10tune
393. 13:11and that also happens to be the topic of
394. 13:13my next video
395. 13:14i'm going to walk through how i tuned
396. 13:16input shaper and basically eliminated my
397. 13:18ghosting
398. 13:19so please stay tuned and thanks for
399. 13:21watching
