Before 2 years when I bought this printer after assembly and first calibration I measured with multimeter what is the actual voltage on those stepper motor controllers and find out what the voltage was fine. I have not checked after that what can be the voltage. I can actually measure now and let you know.

I did measure the Vref fort the A4988 made by Geeetech. The Vref must be within 0.8V-1.2V. In my case the Vref was 0.9V on all 4 stepper controllers. I did raise the voltage to 1V and try to print something someday this week.
