I believe I've finally measured what's actually happening, which is then causing the inaccuracy in the Z position of the hotend. Now, to determine why it's happening.To establish some common terminology, assume the hotend is attached to the HotendPl…

At 80 steps per millimeter, a distance of 0.5 millimeters requires 40 steps, not 4 as you wrote above. I assume that was just a typo. I do see the code:axisStepsPerMM[X_AXIS] = axisStepsPerMM[Y_AXIS] = axisStepsPerMM[Z_AXIS];in Printer.cpp. Why is t…

My mistake. All four of the stepper controllers have 12 VDC on the VMOUT pin. The three steppers which control the X, Y, and Z position have 5 VDC on their ENABLE pin and are working correctly. Only the extruder stepper controller has 0 VDC on its E…
