I cant seem to find any torque-voltage-amp charts and not sure what voltage to run it at or what amperage is needed. Does it just not exist and you need to just shoot in the dark?
So I powered up and it doesnt seem to be working. Communication to the computer is fine. But with power to the motors, the motors just seem to be magnetized on a step and not actually being controlled. Im not sure what he did before, but i read that powering USB without batteries can fry you controller.
I cant seem to get the motors to respong to anything. Power 0 or power 150, "motors on and motors off" dont do anything. But the minute I plug the motor into the controller, it holds its steps. Im powering 19V witha regulator btw.
motor should still work with only 5V from the usb! So I would test each motor lead to see if the resistance is the same on each winding ! if it is not the same your motor is bad!
