  1. TMC Driver

To ensure the TMC driver operates at optimal performance, please use a multimeter to measure the voltage at the green sections indicated in the diagram.

You need to adjust the voltage to 0.81V for the best user experience.

The area marked in red is the potentiometer. Rotate it to adjust the voltage to 0.81V.

Please note that too high a voltage may cause the TMC driver to overheat, and in severe cases, it could even damage the circuit channel!

If the voltage is too low, the stepper motor will not function properly!
