I have a smoothieboard.
The smoothieboard page states the drivers as capable of driving bipolar steppers up to 35V and 2A.
The power input is described as
- Main 12-35V ( Stepper drivers )
I've got 3 Nema23 3.1Nm stepper motors (cnc4you.co.uk 60BYGH301B).
In series mode the stepper motors work at 5.46V, 2.1 A.
Can I use a 5V PSU or will I have to use a PSU higher than 12V as stated in the power input section?
