Filament change speed
It's great that the filament change should be as time efficient as possible, but sometimes the slowness might be faster.
If there is a small resistance somewhere, when feeding the filament from the mmu2s to the printing head, the mmu2s digs into the filament and leaves a section where the half of the filament diameter is missing.
When transporting the filament slow (in these 2cm steps), I couldn't find this kind of filament damage.
Can the high speed move be disabled somewhere ?
Together with continuous cutting the filament on each change, most of my problems should be solved.
