Controlling all four motors

I still can control only three motors, not four motors

Which motor is not moving?

I think that you should choose DEVICE and click to enable motor!

The WEB interface is only X.Y.Z, so I want to control two X motors and I don’t know how to control it.I know how the ARMPS are connected, but I don’t know how to control it.thank you

The web interface and firmware control both X motors simultaneously. It all works the same whether you have one or two X motors.
