      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

        Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is
