PrusaSlicer for MK4s + MMU3 - wrong Filament if Filament change after Paint-on-Supports
My Setup is MK4S with MMU3 and PrusaSlicer 2.9.4.
I noticed on multiple stl's when I change the Filament to one different of default after placing a paint-on-support (and switch Supports to support enforcers only) PrusaSlicer tries to print the support with default filament (usally filament 1) and the body with the selected filament, in my case filament 2. This results in 39 tool changes at one of my stl's. No wipe tower is added.
Changing the filament before placing a paint-on-support the selected filament is used for everything to print.
