My mmu does not download after finishing printing
Hello, I have a problem with the MMU3. Yesterday, I was told to update the firmware, which I did, but I'm still having the same issue. After finishing a print, it doesn't unload the filament, and when I start another print, even if I select a different spool color for the change, it doesn't switch and keeps printing with the previous color. I have mk4s, has anyone else had something similar happen to them?
RE: My mmu does not download after finishing printing
My first suspicion is that you are not really using the "{printer} w/ MMU3" profile. I would suggest starting from default profiles for print, filament, and printer, and modifying manually as needed. The unload is probably in the post-print gcode section but best to get Prusa's full settings.
