I'm trying to use TinyG to control 4 stepper motors. But the 4th port is not working for this application. Is there something different about the fourth port? Can it be used to control a stepper motor? Any suggestions or advice would be helpful since I'm not familiar with this. Thanks a lot in advance.

It does work (at least for me), because I'm using it on my OX CNC Router.

It needs to be configured, and you need to set the current pot, but otherwise I didn't have to do anything special.

My OX has an X motor, 2 Y motors, and a Z motor.

You can find my configuration here:
