Hi. My extruder isn’t extruding. The motor just jerks back and forth. It seems to be skipping steps.
I can move the big cog and extrude very easily by hand so there’s no mechanical issue.
I’ve tried trimming the voltages on the motor driver to everywhere between 0.2-0.8, but it makes no difference.
So i’m guessing i need either a new motor or a new driver?
How do i know which one?
