Extrusion/Material drive problems

Recommended Posts

Hi Ultimaker users,

I got the new Ultimaker V2 and it worked great. During my second print the filament stopped coming out. I took out the filament and put new filament back in. When i start a print it doesn't extrude. I think the problem is in the part on the back of the printer that pushes the material. How do i fix this so it extrudes. Thank you.

There's lots of possibilities but clogged head is more likely. try a cold pull then try extruding *without* using the feeder to see if you are correct. You should be able to push/lift the filament firmly in or out the feeder such that you are doing the extruding instead of the motor. "maintenance" "advanced" "nozzle temperature" - set to 200C and then pull hard. It takes an impressive amount of force to get a little filament through.

Cold pull aka atomic method found here - (do simpler version):
