I am getting skipping when I have my driver set to .3 volts. I get skipping unless I raise it up to .4 or higher. At that voltage, my stepper motor gets pretty hot. I have verified that there are no clogs. I am printing using 3mm filament, PLA, E3dv6 .4 nozzle.

I am wondering it the little nema14 hasn't got the muscle to push 3mm filament. I wonder if a larger idler gear and belt may help?
