Fillament runout problem

I was printing with new MK3 without enough filament on spool, relying on the sensor. Detector found out, there was filament not going in, but when moving the small piece out, it was not guided through the Teflon tube (that was destroyed).

I needed to dismount the top part.

Is the filament tube too short? Where could be problem?

Re: Fillament runout problem

is the bondtech gear ont he extruder motor centered to the filament path? See second photo of step 14 here:

If that's off it might have the filament miss the tube

The teflon tube should be abt. 13 mm long.

Bear MK3 with Bondtech extruder
