Extruder crashing on wipe tower after firmware update
Extruder crashing into wipe tower after update
I've just updated to the "new" firmware, and on my first print I had the layers shift. This happened three times. The culprit is the wipe tower. For some reason, large blobs of filament are deposited into the wipe tower on filament change. Eventually, the buildup will cause the extruder to drag and the motors will skip steps.
This is happening on my CoreOne+. I've got the Coreboxx on top with active smart rewinders by @mire.
I've tried adjusting settings on the wipe tower, and it makes no difference. Eventually the extruder crashes and ruins the print. I've tried this print three times now.
RE: Extruder crashing on wipe tower after firmware update
I had something similar on my MK4S. I found that one of paths from spool to MMU was binding. After checking the others for tension I changed to a different buffer system and problem solved. Check if there is too much tension to pull the filament. Hope you can find a solution.
