Octoprint Help needed. ORIGINAL PRUSA I3 MK3S  

RE: Octoprint Help needed. ORIGINAL PRUSA I3 MK3S

Do you mean a profile for slicing via the Cura plugin in Octoprint? If so, can't help.

If you're just trying to use Octoprint as a general print server, not sure what you mean. I use an generic Octoprint setup I originally built for my Lulzbot, and it works fine. There's nothing specific to the printer in an Octoprint "profile" other than the print volume dimensions, which you can find in the manual that came with the printer, googling, on Prusa's site, etc.

RE: Octoprint Help needed. ORIGINAL PRUSA I3 MK3S

I found this information in the comments on this recommended video ()

Print bed & build volume Width (X): 250 Depth (Y): 210 Height (Z): 210 Check Custom bounding box X Coordinates Min: 0 Max: 250 Y Coordinates Min: -10 Max: 220 Z Coordinates Min: -1 Max: 210 Temperatures ABS Extruder: 255 Bed: 100 PLA Extruder: 210 [modified to 215] Bed: 60 We downloaded and printed the Raspberry PI case for B+/2 & 3 Vers. 2.1 from www.thingiverse.com/thing:2398913.

RE: Octoprint Help needed. ORIGINAL PRUSA I3 MK3S

Do your downloads from octoprint.org.

Prusaprint is really to support the Pi Zero W using GPIO. I don't recommend any part of that.

Pi 3B using USB is the trouble-free way.

Also: PrusaPrint is an image file. It gets written to your Pi micro SD. Use an image writer.

RE: Octoprint Help needed. ORIGINAL PRUSA I3 MK3S

Definitely recommend downloading OctoPi from the Octoprint site and don't use the Prusa version.

@mortalwombat

Noob question. Are you sure about the axes speeds, the only number I see in the spec is 200+ mm/s. I assume the /min was a typo.

[...] Can someone post up the official profile settings for the Mk3s to use with octoprint, also whats going on with the prusaprint image?

There's a nice summary from Gina, the Octoprint developer, here which includes a link to the relevant Prusa configuration file from PrusaPrint which can be found here.

RE: Octoprint Help needed. ORIGINAL PRUSA I3 MK3S

Thanks

RE: Octoprint Help needed. ORIGINAL PRUSA I3 MK3S

Another question regarding Octopi and Prusa MK3S

What's about the printbed profiles?

I have on my Prusa 2 different?

A smooth and the texture one printbed..

Must or how can i switch between the 2 printbeds because normal i would change it on Prusa display menu and of course they have different Z axis adjustments!

@mortalwombat

hey, thanks for this, i am curious and extreemly noobtastic

10.200 is that 10200 or literally 10.200?

RE: Octoprint Help needed. ORIGINAL PRUSA I3 MK3S

@roblob

It’s 10200. It’s mm per minute. 

RE: Octoprint Help needed. ORIGINAL PRUSA I3 MK3S

Could anybody who has been using i3 MK3S with Octoprint please verify if the following values are correct?

Axes

X: 10200 mm/min

Y: 10200 mm/min

Z: 720 mm/min (10 times slower than E?)

E: 7200 mm/min

All Invert Control unchecked.

@mortalwombat

thanks much! I appreciate the quick response. Octoprint is a blessing and a curse lol. 

Peace and Health!

RE: Octoprint Help needed. ORIGINAL PRUSA I3 MK3S

@mortalwombat

Question, 

 Octoprint constantly tells me the print is out of bounds, I have read that it is the first purge line. So i add the check box and do a -4 or so, is there a good standard to get rid of that warning other than disabling it?

Thank you.

RE: Octoprint Help needed. ORIGINAL PRUSA I3 MK3S

@roblob

Check if you have "Enable Model Size detection..." checked under "Features".  If so, uncheck it.

There's also a feature under the profile definition to define a custom bounding box. I haven't used it, but you may try play with that to include the initial wipe region.

RE: Octoprint Help needed. ORIGINAL PRUSA I3 MK3S

I know this is a bit of an older note and wanted to share how to fix it by configuring the i3 MK3S correctly:

Following the instructions from https://help.prusa3d.com/en/article/octoprint-configuration-and-install_2182/

the key is to enable custom bounding box and change it to X: 0/250, Y: -4/210, Z: 0/210

Hope this helps
