Motor disconnect warning, stepper moves random direction

Hello, I'm setting up a CNC machine, it's a Sherline 5800, nice machine. I get warning on motor 1 (which is my Y axis) about a possible disconnect on phase A.
Checked the cables and connectors with a multimeter, and they seem sound. Tried another motor port, same problem.
The odd thing is that the motor moves in a random direction with each command. Pressing +10 might make it move one way or the other.
I'm thinking possibly the error may be at the crip connection to the board. I might crimp them again, and report back.

@oribotic if the error follows the motor that would definitely indicate a wiring issue
