General Mach Discussion / Re: Help wiring limit switch to servo tec board

When I tried to wire two switches I can’t get them both to work on the same input, only one.  I tried every combo in all the posts I found.  How should pnp’s be wired so each can trip independently?

Again, thanks.  I got it to work, in part by doing just as you said.  The biggest problem was that the board seems to be reversed, it is labeled 24v and 24 neg but the switch would not work until I reversed those.  I tested with a 9v battery and the switch worked exactly like the diagram it came with, when I put it on the board it would not work like the diagram until I reversed it.  Weird.  I concluded that the board it labeled wrong.

I wired in a pnp nc switch, light is on, light goes out near metal.   Appears to be working.  How to configure ports and pins in mach3?  On the diagnostic page a yellow light is on beside the switch but when i jog in either direction and activate the switch nothing happens.  All the examples I found reference a BOB.  My switches are on the main ST10 servo tec (industrial board).  The only other thing in my cabinet is the ESS board.  Any suggestions??

Thank you soooooooo much.  I will get one of each, NPN and PNP, and try them wired as you suggested. Thank you for simplifying it for me, much appreciated!!!!

Thanks for the response.  How do I know which of your examples applies to my board.  I did a little internet searching and am more confused.  Anyone out there have a Procut CNC version of the PM25 with limit switches that could share a pic with me??

Noob here.  I know very little about wiring, luckily the machine I bought is mostly done.  I want to add limit switches.  Can someone tell me how to wire the switch to this board (trying to post pic also).  It is a PM25 originally done by Procutcnc.  I am the second owner, Procutcnc will not respond to me, the previous owner warned me that their customer support was ZERO.  Hoping someone can give me a quick answer as to where the two switch wires should be plugged in to the board.  The board has 4 spots for each axis (+24v, in-, in+, 24vgnd).
