Nomad Pro Spindle Not Moving

Hey guys, a few months ago the board on my Nomad crapped out and Carbide sent me a new one very promptly. However, I didn’t get around to installing it until tonight. :stuck_out_tongue:

Everything thing seems to work except the spindle. One possibility is that the two boards come together, but the connector between them isn’t going in as deeply. I’m assuming the smaller board is to drive the spindle? If that is the issue, any thoughts on how to make it fit without breaking anything?
