NinjaFlex 3mm 250-260C 0.2mm layer height with an .050 nozzle 20mm/sec max speed This has to print very slowly, the NinjaFlex doesn't melt very fast, and trying to cram too much of it into the extruder just jams up.

Re: Extruder keeps slipping

I regularly swap between the ceramic heater and the v2b hotends. 185C on the ceramic is about 210C on the v3b due to the temperature gradient (acking previous post!) If anyone else runs into this issue (extruder skipping): 1. Remove variables like the PEET tube, spool, use known good filament, etc. ...
