Troubleshooting:
•
T: My stepper motors are shaking/juddering/jump around/ move in
the wrong direction occasionally.
A: This is usually caused by a loose wire or connector, or from the connector
being placed incorrectly (only on 3pins and not all 4 pins on the RAMPs board)
Another cause is the motor current being set too low or too high. Try turning
the adjustment potentiometer on the stepper motor driver 1/8
th
of a turn
clockwise to increase the current to the motor slightly (or anti-clockwise to
reduce the current), some experimentation is needed here.
