Adjusting the voltage on the stepper motor driver

[Lami René]

Hello,

Here is my procedure for adjusting the voltage on the stepper motor driver:

If the serrated wheel slides on the filament, it is because the pressure of the clamp on the filament is too low and it is necessary to adjust the clamp for more pressure on the filament. The serrated stepper motor must never slide over the filament, it is important!

So the serrated wheel of the stepper motor never slips on the filament, but if the motor jumps, it means that the motor driver's electrical adjustment is too low and that it must be increased by The tiny potentiometer directly on the controller card driver. The usual voltage value required is between 0.6 and 0.7 Volt.

Measure and adjust the electrical power of the stepper motor driver by using a DC meter (circle # 1) connected by the black multimeter cable to the metal cover of the controller card's USB port (frame # 2). And the red multimeter cable to a small conductive metal screwdriver (circle # 3) and directly into the metal slot of the pilot's mini potentiometer (circle # 4).

There are the three drivers for the belt motors and the three pilots for the extruders which can be adjusted independently. But for me, as I am beginner in the matter they are all set to 0.6 Volt (± 0.004 Volt).

Cordially,

Friend René
