still having major issues, the feeder itself seems fine, can push filament without the hot-end in play...
after I've cleaned the nozzle, atomic-pull, etc, a print will go fine for the first couple layers, then the print will get less and less dense until it finally stops extruding anything from the nozzle.
I've replaced just about everything in my UMO hot-end. Nozzle, Aluminum block, PEEK, brass pipe, PTFE coupler...
I'm wondering if my thermocouple might be bad - is there any way to diagnose this?
it is just about the only thing I haven't replaced!
really need help here, as I'm getting ready to chuck my UMO with a trebuchet
