Do I need to ground the PMDX 424 board to earth ground. I have my PMDX 424 attached to a plastic control box with Teflon standoff spacers and screws. Should i run a ground wire off one of the mounting post on the PMDX and the other to earth ground. Just Checking

SmartBOB controllers and dedicated accessories / Setting up proximity sensor

« on: April 10, 2016, 06:58:54 AM »

How do I connect the proximity sensors the the PMDX 424 and setup Mach4. I connected the blue wire to com the brown wire to 12v pos+ and the black wire to screw #1 on the input side of the 424 spot j16 went to mach4 configure then to limit singles and that where I get stuck. I tried input 1, motor 0 -- with no luck. Only get a light in the machine diagnostics and a limit switch fault in the history line. Any suggestions
