Hello,
I'm in the process of building a core xy machine with dual Z bed. I'm using duet 2 wifi board. One of the motors turning half the steps as the other. If one is turning 2 the other is one. I have one of the motors connected to E1 the other to Z output.
I have swapped the connectors (Z to E1, E1 to Z) and that particular motor is still turning half. They have detachable cable, I have swapped their cable to make sure it is not a wining issue, still same motor turning half the steps.
Is the stepper toast?
