Wher4e did this part come from (K2 Plus)
Long story short, I was getting repeating "FR0122: Spool holder filament in use. To print with CFS, unload spool holder filament and reload CFS/CFS Lite filament before printing." errors.
I disassembled the extruder (multiple times), and got to a point where I was trying to reproduce the error with the filment break sensor unplugged. I simply put the front on, and told it to print knowing I would need to take the whole thing apart (AGAIN!) to plug it back in.
Well, the print head moved back to the poop shoot area and the front of the extruder came off, spring flew out of the pressure lever, gear flew out, and this thing.
I have been looking at the entire hot end and I don't think it goes there. There's not an axis that is empty around the poop shoot, the motion is moving OK by hand so I don't think it from the motion system.
So anyone know where this arm and bearing came from?
