I am not able to get the E stop working. I have all axis steppers up and running through smooth stepper and the KL- DB25-5 BOB. I have rewired the e stop to use a pin for the limit switch, but that didn't work either? I checked the continuity of the wires, e stop etc. I measured .8vdc to ground on all the inputs off of the BOB. What should I be seeing? 5vdc? I've tried to get help from Automation Technologies for the last couple of days, but they don't seem to want to help? I think it might be a bad BOB, but I'm not sure? I bought all the electronics through them including Mach 3 but I'm not happy with their support. I thought buying all the components from them would be best for support, it did't matter. Any help would be greatly appreciated.
