extrution problem - solved but be usefull for others

[duvdev]

Hi all,

So I started a 12 hours print and about 2 hours later I saw that the printer is working but with no extrusion at all.

I check the temp and I saw the the extruder motor is working - reheat the hot end but no extrusion at all.
I touched the filament the I saw it aint movine and it it moves it wont be smooth as it should be. I disassembled the exdruder and I saw that the teeth on hobbed Drive Roller - the one that sit on the motor shaft and push the filament are full with filament leftovers.
I cleand is all until in shine and it works like new.

This one is going to the my maintenance routine .

Hope it will help you one day.

If you are using ABS just check the extrusion temp. Seems u are at low temp
