Cfs does not inialize when I try by removing and installing cables it lights up but says jam between cfs and hub which is clear
Flip the CFS over and look at the bottom. I have had filament break off and get stuck there. If not there then check the print head itself, there is also a sensor in there that detects filament. I think its supposed to glow blue when there is filament detected and off when there is none,
Someone correct me if i have that backwards. in not near my machine.
