General Mach Discussion / Mach3/MX4660 Zero-Plate Issues
« on: June 15, 2019, 01:58:27 AM »
Hi friends,
N00b CNCer here, and brand new to this forum. Trying to get to the bottom of an issue I'm having with implementing a zero plate install. I have my limit switches all plugged into input 1 on the mx4660 controller, with a pull-up resistor (inputs 1-4 are nominally grounded).
The common practice I've seen seems to be to install the zero plate in Input 4 (pin 13 in Mach3). This also gets the pull-up resistor (or in this case a pull-up jumper) to power, and in the ports and pins, I have Probe mapped to Port 1, Pin 13, Active low.
Now ideally, it seems like if I touch my clip to my zero plate, pin 13 would go active, and the digitize light should light up on the diagnostics page. This is not the case. Instead, the machine thinks my limit switches have been triggered and it goes into e-stop mode. Doesn't seem to matter whether I'm on Input 2 and pin 11, input 3 and pin 12, or input 4 and pin 13. All result in the same behavior where if that input goes active, its an e-stop.
This is confirmed with the Plugin Control -> Data monitoring which flashing pin 15 regardless of whether I'm toggling pin 11, 12 or 13.
Any suggestions would be greatly appreciated. I'm sure this is the wrong place for this post, so mods feel free to bump me. I didnt see any mx4660 or leadshine headings in the tech support section.
thanks all,
John
