Z Axis Motor not functioning - board problem

I recently assembled my Maslow CNC 4.1 and one of the z axis motors does not power on at all when I attempted to lower the z axis for testing.

I took everything apart and swapped the motors and the same thing happened on the same side, so there is an issue with the board.

@bar I see in some other forum posts that there was a bad batch of boards at some point. Are you able to see from my order if I was possibly affected by that batch? Thanks for any help, it is most appreciated!

This does sound like exactly the symptoms. I will DM you a code right now!
