4.2 Driver Current and Microstep Settings

Properly setting the driver current and microsteps is crucial for motor performance and accuracy. Refer to the diagram below for common driver types.

Orientacions generals:

• Interruptors DIP: The DIP switches in the driver slots are used to set microstepping. 'OFF' typically means the switch is flipped downward (towards the numbered side), and 'ON' means flipped upward.
• Ajust actual: Use a multimeter to measure the Vref voltage on the driver. The default current is usually 1A.
• A4988: Default Current: 1A, Maximum Current: 2A. Calculation Formula: I = Vref / 0.8.
• TMC2209: Default Current: 1A, Maximum Current: 2.5A.
• TB67S109: Default Current: 1.66A, Maximum Current: 3.32A. Calculation Formula: I = Vref * 2.

Adjust the Vref potentiometer on each driver to achieve the desired current for your stepper motors. Consult your motor's datasheet for optimal current settings.
