So basically the toolhead has worked perfectly. After a long period of non use I am having issues with the toolhead gripping the filament.
If I push the filament in manually after the homing and heating process it works. If I dont it will not be able to grab and extrude.
I have tried
a) Making the knob all the way tight
b) making knob a little looser
c) cold pulling
d) heating, removing and extruding any extra filament.
Anyone have any tips for how to solve this?
