I just setup my brand new K2 combo. It did its calibration and then updated the firmware to newest version 1.3.6. Got all excited and inserted filament into the 1a filament slot and the tube for that slot. Blue light comes on. I have to hold the filament in place to keep light on. The machine tries to load the filament, motors churn and nothing happens. Eventually I get a message the filamenthas run out or an error saying there is a blockage that needs to be cleared. I haven’t run any filament through thus CFS so I’m not sure what is happening. I have cycled power and no different behavior.
Any help is appreciated.
Make sure your filament is actually going into the cfs motor. I find if the tip of the filament has too much of a curve to it, it will feel like it’s going in, but is actually hitting the lip of the extruder and not going into the path correctly. I bend the curve out a bit and it will feed thru.

Hi!
Did you get any error code on the printer screen? You can check the possible solution of your problem on Creality Wiki - CFS Error Code Summary | Creality Wiki. As I see this is probably this error:
FR2836
Error description: When feeding, the filament passed the hub detection, but could not trigger the extruder detector. It may not be able to reach the extruder material break detection smoothly, or the extruder material break detection may not be triggered normally; usually the resistance of the Teflon tube above the printer drag chain is too large, or the bending angle of the Teflon tube above the extruder material break detection is too large; or the extruder material break detection is damaged and cannot be triggered.
I would check if all tubes are empty and connected properly. Check the cutter also if there is no filament pieces left.
