Ok, so when I first built this, I had an issue with the Z axis going up instead of down. Fixed that.
Got excited when it started printing something. It got about 3/4 of the way through the first layer, and now I can't get anything to extrude. I'm looking, and apparently the person I'm building it for bought TPE filament instead of PLA or ABS. Could that be what's causing my issue?
On top of not extruding, I can't pull the filament out of the extruder anymore. I've used considerable force too. I disassembled the extruder, removed the clog, and rebuilt it. It printed about 2 inches of plastic, and jammed again.
I'm seriously suspecting the TPE right now.
Any thoughts?
