So, while calibrating my machine I noticed that my z-axis seemed to be moving more than it should. I checked my stepper driver ms1,2 and 3 voltages and 1 and 3 are reading 5 volts while 2 is reading zero. I've tried other steppers and they have the same issue so it must be something with my RAMPS 1.4 board. I've also tried resoldering the ms2 jumper connections and the ms2 pin for the stepper driver hoping that would fix things, unfortunately it didn't. Where else should I be looking? Are there any other ways to diagnose the issue or to work around the issue? Worst case seems like I could just move the z-axis motors onto E1 instead but it would be nice to have it running on the z stepper if possible.
Thanks,
Kevin.
