Stepper Motor Current on LongMill

The current going to the motors is controlled by potentiometers, which are on the drivers of the control board. If the motors are taking in too much or too little current, it can cause issues in operating the machine, such as overheating and stalling.
If you are seeing these issues and you have tried everything else to troubleshoot them, you can refer to this article to ensure the potentiometer is set correctly at 2.2A.
