Hi all, I've just installed the K1 Max CFS Upgrade Kit, and the CFS will not run the filament to the hot end. The video clip shows me telling the K1 to extrude. The CFS runs the filament through the buffer without issue, then through the filament sensor and about an inch after that, it stops. The K1 one then continues on with the extrusion, but no filament is reaching the hotend. There are no error codes, no jammed filament (CFS extracts without issue, and I've examined the buffer and stripped the CFS), and I can't find this issue online anywhere. Any advice would be greatly appreciated.
