Anyone using @octoprint with a prusa mk4 and mmu?

Ive not tried it yet as the builtin WiFi is pretty good, octoprint is just so much more powerful and feature capable in general

@sldrant

I've got a setup with Octoprint, an MK3 and a MMU2 at Work.

Octoprint is the most reliable part of the whole Setup by far.

@sldrant @octoprint not exactly, but I am using octoprint with a mk2.5s and an mmu2s. Works like a charm.

@jeroen @octoprint @dekkia

Can you override the mmu reel used when starting a print? I often have single colour prints I start and currently have to select which slot to use on the printer. Would love to be able to do that on a remote print start

@sldrant @jeroen @octoprint

When I do single-color prints I select the color I want in the Slicer.

I'm not aware of an option in Octoprint that allows you to select the filament post-slicing.

@dekkia @jeroen @octoprint OK, thanks that's what I thought I'd have to do. Either reslice or swap the mmu slots.

The mk4 let's me on the screen swap the filaments (or set two spools to be used when one runs out)

@sldrant @dekkia @octoprint if you use octoprint to start a print sliced with a single color profile you still get the option to select which spool to use on the printer’s display. Selecting this in octoprint might be possible, but it would require detecting the specific gcode that triggers the selection dialog and replacing it with other gcode that indicates a specific spool. There might be a plug-in for that, I don’t know.

@sldrant @dekkia @octoprint Just did a quick search, and there is, indeed, a plugin for that: https://plugins.octoprint.org/plugins/prusammu/

@jeroen @dekkia @octoprint oh thanks! Must have missed that when I got the mk4

@sldrant you can fix this issue by loading filaments into the mmu, then choosing the Load fikaments advanced option on the printer UI (not looking at it right now so name from memory), then it doesn't prompt you any more

@castaway I usually want the prompt, to select colour. Or if I've a single material print, I want to choose while mmu slot the correct material or colour is loaded on, rather than having to reload the filament.

(multicolour prints are sometimes easier to reload the whole mmu, but instill do just map it on the printer for some prints)

@sldrant @octoprint I use it with my mi4 and the MMU. It’s so much better than the prosa software.

@thomas is the mmu annoying with octoprint?

Basically trying to work out if I can fire any old single colour print at the server and then choose the filament to use when starting it? Currently am doing this by uploading to printer and then starting it via the screen on the printer to select the right filament override

The MMU works well with #Octoprint. I use Octoprint mainly because it offers me more options than the Native Prusa solution. You select the material in the slicer - which should of course be loaded in the MMU - and then send the print file to Octoprint. Octoprint will ask you if you want to print with the submitted filaments or something else, or if everything is ok, and then start the print.

Of course, this requires flawless interaction between the MK4(S) and MMU3 at the hardware level. I had some initial problems with this, but they had nothing to do with Octroprint.

In the meantime, I have made some extensions [(un)original heatbox, different buffer system, housing and a few other small things] so that I could start production.

@thomas oh nice. Will have to set it ip and try it. Sounds pretty good.

Not had many mmu issues, other than pla breaking in one of the bowdens
