special note

Precautions for adjusting the driving current of stepping motor

1: When you adjust the potentiometer to change the output current, you must remove the stepping motor first, otherwise the TMC2209 will be damaged

 2: When you measure the voltage of the potentiometer, you must connect the 24V power supply. USB power supply is not enough.

 3: Take care that the radiator does not touch the pin.
