General Mach Discussion / Re: Mach3/MX4660 Zero-Plate Issues

Thanks for all the responses.
TPS, I found one of your other replies to a similar problem on a different thread and I realized my mistake was not powering the OPTO2 channel, which as you described above leads an external logic high on input 3 & 4 to throw an e-stop error. Jumper OPTO2 to +12VDC brings Inputs 3 & 4 to 12V and gets their internal circuit juices flowing correctly (can you tell I'm not an EE? haha), so then the zero plate is connected to input 4 and ground only (no jumper from +12VDC or OPTO2 to Input 4, that seems to be done internally). Works like a charm.
For future people having this problem with MX4660 & Mach 3, config is as follows:
1) Jumper OPTO2 to +12VDC n (Failure to do this will cause e-stopping when to activate input 3 or 4)
2) Zero Plate leads connected to Input 4 & Ground
3) in Mach3: Config-> Ports & Pins -> Input Signals tab: Set PROBE to "Port 1" , "Pin 13" and check "Active low"
4) Watch and download Gurubrew's code from here https://www.youtube.com/watch?v=G4DeVa8rzA0
Thanks everyone for the help.
