MPG handheld does not work

I had a similar problem with a different style of MPG but then realised that the Controller needed both power supplies to work. The MPG LED would light with the system power supply but it would not detect the switches and e-stop. When I went to the test page on the DDCSE, I could see the rotary working.

Adding the second power supply bought the rest to life. Buried in the instructions states that you need the IO power supply. The rotary was backwards, but changing parameter #175 fixed that.

There was also the problem where the 5th axis did not work on the MPG. I worked out that the X1 wire was wired where the 5th axis was supposed to be (no X1 on the DDCSE connector). Swapped the wires over (cut the gray wire in the connector and soldered the pink to it) and everything now works great.
