Warning FR0122

I keep getting this warning can someone help please. Spool holder is NOT connected it has been removed when i connected CFS

Spool holder filament in use. if CFS filaments are required retract the spool holder and restart.

Thank You

I feel your pain.

I am having the same issue. I have disassembled the printer head, checked it all, checked the buffer, ran filament through the tubes, switched to the spool, printed great, switched back to CFS, error FR0122 Spool holder filament in use. I am going to roll back a Firmware or two to see if this resolves. I had no issue at all, and the only variable that changed was the firmware update before this round of printing.

What I did eventually is replace the nozzle which was partially blocked and it sorted it out and is printing perfectly…

Funny enough, I was trying to restore to factory default, and I can’t, because filament was detected in the extruder…..hilarious
