Color change at layer height
Prusa slicer 2.7.1 - mk3s+(fw: 3.13.2) - mmu2(fw:3.3.0.1).
i am attempting to do a color change at a layer height (at 4mm) when i select it on the bar, the reslice does not show the color change but i see it indicated at the bar. when i send the print to the printer there is NO color change or even a pause.
i look back at the project and when i mouse over where the change is to occur i see the message:
' Color change ("M600 G1 E0.5 F1500 ; prime after color change") for extruder 4. NOTE! There is a color change for extruder that won't be used till the end of print job. This code won't be processed during G-Code generation'
(see screenshot for context)
what is this message and how can i specify a color change at a layer height?
RE: Color change at layer height
wow, that is strange. I do manual color changes without an mmu, but I haven't seen this one yet.
Questions to you have an mmu connected?
In printer profile do you have multiple extruders set up?
RE: Color change at layer height
So to answer your question yes, the mmu is connected and works without issue.
with a little more more experimentation and work on this issue. Since I only had one color change, i set the wipe options to wipe into the print infill and no wipe tower. If I remove the wipe options from the object, and let it generate a wipe tower, it will successfully print both colors and not have the error. It looks like this might be a bug of some sort with the combination of options I chose. Kind of stinks, I really want that real estate on the bed, and my prints are big enough to hide the layer color change in the infill.

I noticed this the other day I fixed it by going mmu single color mode. You could always file a github issue
