Note: When checking Vref, do not connect motor, but connect power and USB power. When tuning Vref, first turn to smallest in case of burn output
Double check board direction before power up, wrong direction will burn all
Double check board direction before power up, wrong direction will burn all
Check Vref, output current is Vout = Vref/0.5, default Vref is about 0.4A
Setup Vref, clockwise -> current increase, counter clockwise -> current decrease
Micro-step setup:
- Measured voltage: Vref --- Drive current: I --- Drive resistance: Rs = 0.1
