MMU2S Acting as MK3S
Hello everybody,
I have whitnessed some strange things going on with my MK3S+ and my MMU2S.
I unfortunately uploaded the wrong file to my printer, one for a single, non mmu mk3s.
I did cancel the print as soon as i saw no filament being loaded.
Then i uploaded the single mmu version of my print and started printing. It was directly weird, because i did not get asked which filament to choose. So i cancled again.
I remembered that the firmware of both mk3s and muu2s were out of date, so i flashed both firmwares on the boards.
Next try. Freshly sliced, in mmu mode this time, with filament 5 selected in prusaslicer.
Uploaded to the sd card. Now it got even weirder.
Start print
Heat to temperature
calibration
Filament loaded
Pressure line is not being printed
Filament is being unloaded and mk3s promps "remove old filament and press knob to resume..."
I thought ok, and did so.
Filament loads again
Print finally starts (without pressure line on front) the extruder randomly spins like a motorbike for 2 sekonds and tries to extrude. Then the print resumes, but nothing is being printed, because the mmu stepper is engaged and does not let filament go into mk3s
I am very very confused, i thought it was a software problem, but i flashed all firmwared multiple times.
Anybody has any ideas?
