Filament up and down and up and down: Why does this happen?
My MMU likes to move the filament up to the top of the non-bowmen tube, then back down, then back up, then back down. It will often do this two or three times. While it often becomes happy, sometimes it ends in an MMU failure.
Why is it doing this? What does it think the problem is? Is it some sensor or adjustment?
And most importantly: What are the typical steps of correcting this from frequently happening?
Anybody? Any thoughts? Does this happen to others using the MMU2S?
