A10M Vref for Stepper driver

Post by Niyoki » Sat Apr 20, 2019 3:42 pm

For stock Geeetech A10M which Vref Voltage is the best? I checked all all five drivers is 0.8 Volt.
Under A10 Faq i found this.

1.4 Check the voltage of the motor driver and the motor connector.
Measure the voltage of the driver board, normally the value should be 0.8V-1.2V, you can put the red probe of multimeter on the potentiometer,

If they are ok at 0.8 leave them there.
I'm assuming you've got the stock A598 drivers which are the noise ones. For those anywhere between 0.8 and 1.2 is good.
If you're experiencing issues at 0.8 try increasing to 1.2

If you have TMC2208 drivers (The quiet ones) then 0.8 is the correct value.

Thank you @vert ,
I changed all A4988 Vref voltages to 1.2 Volt. Everything works smooth and not more heat than with 0.8 Volt.
