Prusa Slic3r batch (Command line interface) with MMU2S - How to?

Hello,

 

i want to use the Slic3r CLI (slic3r-cli) interface to generate gcode for a multimaterial print. For the normal Prusa i3 MK3s (without MMU2s) it was easy to setup. But how to generate gcode for a multimaterial-print? I checked the cli-help (you can call it by prusa-slicer-console.exe --help-fff) without finding a solution ...

My questions: How to specify that model1.stl should be printed with filament 1, model2.stl should be printed with filament 2 and so on ...

 

Thanks in advance

Jens

Hey Jens,
Do you have any updates on your process to get  the mmu-stls working using the command line?
Glad I found someone that also wants to do this.

I'm trying to do the exact same thing.  Anyone have any luck with this?

I finally solved the problem with some python scripts and the prusa cli.

To combine single stls to an 3mf file i wrote a small python script which combines the stl and assigns the extruder for each stl.
This 3mf-file can be used with the prusa-cli to generate gcode.

If you are still interested in that i can share you the code via github 🙂

Definitely interested. I regularly print batches of multi-colour prints and it gets to be a real pain going through a dozen sets of three STLs assigning the filaments. Creating the STLs is scripted but it appears that a lot of the command line interface of the slicer is either documented incorrectly or just doesn't work as described.
