>RepRap community members have reported StepStick boards with short-circuits in them! Obviously this might destroy both your StepStick board and your electronics board. Before installing a StepStick board always verify with your multi-meter there are not short-circuits on the pins.When stepper motors are in operation and stand still they still use current. For this reason each stepper motor controller has a potentiometer to control how much current is sent to the stepper. If you send too much current you might use more current than is required (and hence increase your electricity bill.)When stepper motors are in operation and stand still they still use current. For this reason each stepper motor controller has a potentiometer to control how much current is sent to the stepper. If you send too much current you might use more current than is required (and hence increase your electricity bill,) or even overheat the controller IC or the stepper motor.For this reason is it advised to close the potentiometer on each stepper motor controller by turning counter-clockwise all the way and then open the potentiometer about ΒΌ th of the way. When you discover one of your steppers does not provide enough torque you can open the potentiometer of that stepper motor controller at little bit further.
