OK, I got my TAZ 5 today and everything was great; I put it all together and loaded Pronterface, leveled the bed and wanted to run some calibrations.
But I tried to extrude 5mm @ 100mm/s to clear the white material that Lulzbot used to run the test piece, but I keep getting a little squirt and then the hobbed bolt does the half moon thing!
Extruder temp is 185 material is PLA.
So I pull the PLA, trim and repeat. I’ve tried several (5?) times, same result.
