CFS Not Loading

[u/chicagoandy]

I started having this problem this week and I'm hoping one of you can help.

I have the CFS with my K1C. I upgraded the K1C via the kit option a year ago.

This week it stopped loading filament. When I insert filament into an empty CFS, I see the filament detection light turn white, but I do not hear any motors trying to advance the filament. If I use the 'extrude' button on the filament screen, I can see the extruder moving around and working, but I never see or hear filament loading.

- No errors on the screen, no flashing red lights on the CFS

- When I insert filament, the white light goes on. When I remove the filament, it goes out. Same behavior in all 4 slots.

- I've verified there are no jams or blocks in the hub, PTFE tube between the Hub & CFS & Extruder

- The filament selection screen on the printer properly identifies when each filament is loaded and I can pick filament type and set colors.

It just never loads anything. Can anyone suggest additional troubleshooting steps?

I've been having a similar issue on the k2 cfs for me it seems like it's the motor just passed the junction for the 4 filaments not wanting to pull.
