Some feature requests for MK3S/MMU2S
Currently running 3.7.2 and 1.0.5
1) When I select a single-color print from my SD card, I'm given the option of picking a filament, but there is no option to cancel. I have to select a filament in order to cancel the print. This often continues into issue 3 below.
2) I am unable to cancel a calibration once it's selected.
3) If I cancel a print while the MMU2S is performing its calibration / homing procedure, the print seems to have canceled according to the LCD, but the extruder motor still spins for a long time. This can cause other issues unless I reset the printer. Maybe it would clear on its own if I wait longer but I haven't been that patient yet.
RE: Some feature requests for MK3S/MMU2S
These sorts of requests need to go over at the github page https://github.com/prusa3d/Prusa-Firmware/issues for printer firmware requests. These forums aren't monitored for software issues as they are more of a user community.
