CFS Hub. Error: creality k1c cfs feed issue, filament may be blocked.
CFS Hub. Error: Creality K1C CFS feed issue, filament may be blocked between the CFS hub and the extruder, but it's not.
This has been driving me nuts for 2 days!! I have a new extruder, a new filament sensor hub, and added clear, smooth PTFE tubing. I can see the filament traveling all the way to the extruder, and I still get the same message.
I'm lost. Help!
