I have a 1984 Hurco SM1 with the stock proximity style limit switches that were functioning prior to replacing the Hurco control with Mach3. I am using a CNC4PC C23 breakout board, Smooth stepper, Viper200 servo drives. The problem I am having is I have 5v going to the limit switches, as checked with a meter, but when I trigger one of the limit switches, doesn't matter which one, I don't get any voltage back from the limit. I have attached a scan of the Hurco wiring diagram for reference. Any help would be appreciated. Tom   |
