Will do. Our power supply is a custom 24/12/5 common ground system. Works well with GE controllers but I will follow your advice just to be sure.
I was also mistaken about the plugin reading the encoder... It appears there are 3 radio buttons: Load Enc, Motor Enc and Commanded. I had the Load Enc selected. With Motor Enc I see no updates but get movement. Oddly if I move slow it will not error out (which it should since there encoder is not being read it appears)
I checked the driver with an oscilloscope and determined the driver is indeed putting out information so I am not sure where the issue is. We have a custom cable (verified pinout) using cat 6 shielded ethernet cable from the encoder board to the driver. A, B and Z are all connected.
We followed standard ethernet pinout on the encoder board so assuming the order is ow, o, gw, b, bw, g, bw, b then it is connected properly. We also checked that J8 is the expansion being used (as also verified by the estop earlier).
We also updated Mach to the latest, updated the firmware on the Integra and the Mach 4 plugins.
Do you have any ideas?
