Dear all,
I have built the tachus42 driver board and it worked perfectly with small steppers.
I plan to use it on bigger steppers with different specifications. Two of the motors are identical and rated 3.4v and 2.84A. The third one is rated 4.2A but the voltage is not specified on the motor.
My question is can i use a 12v power supply independantly of the motors voltages? Or the power supply voltage must be less than the minimum motors voltage?
Thx in advance
