Extrusion problem
Re: Extrusion problem
I had several failures even after I cleaned up the hotend. Extrusion suddenly stopped in the middle of a print and the filament drive path was clogged. I can manually extrude just fine after I unclog the filament drive. I think the culprit is the printing speed, somehow white PETg needs more time to melt compared to black PETg. After I reduced printing speed from 3200 mm/min to 2800 mm/min, extrusion never stopped so far
