I just upgraded to the mmu2s on my mk3s and have a few issues
1# cannot figure out how to print a single colour print with anything other than the first filament tube
I use the Original Prusa i3 MK3S MMU2S profile and set the print two tube 5 on and printer still prints with tube 1
2# it seems like the printers flow rate keeps dropping down to 95 instead of 100% it used to work great before the upgrade but now every time I start a print I have to go in to "tune" and set the flow rate up to 100% is there any way to save that seting
3# when doing a multicolor print a large portion of the time when it's trying to do a filament change it seems to push the filament all the way down not get it to grab and then it retracts it and it does that three times and then I have to unload the filament manually and cut the little bubble off the end of the filament is there any way to tune the printer to not have the extra bulge on the end of the filament because it can be very hard to pull the filament out of the Bowden tube because of that
