Hey everyone,
My CFS started complaining suddenly. Two of the slots (3 & 4) started failing when loading new filament (or using the extrude button to test). It feeds all the way into the machine, but never hits the extruder, and a slight buzzing (grinding?) sound occurs, and machine throws a code (FR2836). I scanned the QR and went through troubleshooting steps, but nothing changed.I couldn’t retract filament so powered machine off then on and got it to extract. Now, when I try loading new filament in either slot (3, 4), I feed it into tube inside CFS, but it never ‘grabs’ it to load. I took tube off and fed a bit of filament in to make sure there was no blockage (there wasn’t). So basically there’s two problems:
- can’t load filament - feels like there is resistance, but it never ‘grabs’ and loads
- FR2836 feed issue
Slots 1 & 2 work fine. Anyone have suggestions or troubleshooting steps for loading the filament? And bonus points for the FR2836 issue?
Thanks!
Bryan
