@wnica said in Control motors with rated current higher than Duet Max Current?:
Is it possible to drive a larger stepper motor (a Nema 24 with 3.5A/Phase rated current in my case), with the onboard stepper drivers?
I don't really want to risk to blow my driver when connecting the motor... I don't want to drive the steppers with the full 3.5A, about 2A (<duet rating) would be sufficient.
So can the drives handle a motor with a rated current higher than the capabilities of the drive? I'd say yes, but asking just to be sure.
It's safe unless the inductance of the motors is very low. Do you have a specification of the motors?
