So I started fiddling around again with the CNC control board again, and dropped down the acceleration speed of the motors, which stopped the motors from studdering. I haven’t tested out any microstepping yet (I don’t have any jumpers on hand for the control board), but at single step control, we got the x axis to move pretty well.
I noticed however, that there are some issues in stalling in the motor, so we’ll be trying out some different power supply voltages, adjusting current, and just seeing what works best overall.
