Hello to everyone,
over the course of the last months, I have built my own 3d printer. While running a test print I realized the filament wasn't coming out at all. I have tried moving the pot on the extruder driver because the extruder makes a humming noise when it's trying to push filament through but can't. I have unclogged the hotend about ten times by now and haven't solved anything: when the extruder tries to push the filament it doesn't come out and gets stuck inside the hotend. I'm a bit lost and don't know what to do, does anyone have any suggestions? Is it possible I have to buy a new extruder and/or hotend?
Don't hesitate to ask for more info.
Thanks in advance!
P.S. I have a Bowden setup
