Hey everybody, I have issues with the homing switches working at the electronics shield. I took a meter and checked the continuity of the switches them selves they definitely work. Next pluded in the provided plastic terminal with the black and red orientated correctly and touched them together to act as the switch would... no responce/didnt do anything. At one point I did have the x+ switch stop the gantry upon homing cycle but not the others. Now it wont work. What causes this?

Have you done the 'Verbose Output' test? Put UGS in verbose mode and then hit the switches. Ensure you are on the NC contact (should had a small cap on it I think) and hit the switch and look at the UGS output while it is activated. If that does not work, someone else will have to chime in - could it be a firmware or settings issue as well?

Make sure the wire connections are good. Check continuity at the end of the wires and through the switch. Sometimes the wire breaks at the clamp-on connector.

Bruce i checked all continuity, switches work fine. Electronics do not, is this a common problem. Motion controller moves on no matter how I try to initiate the N.o circuit by crossing the wires at the electronics shield plug ins x+ y+ so on prongs. No responce from them at all

Hmm, are the switch connector going the correct direction? I believe each channels pins are left/right of each other: ex X channel: +X -X Y Channel: +Y -Y not: +X +Y -X -Y
could that be the problem? This would keep the circuits from activating -
If not, re-flash the board, also inspect it for bad connections someplace or burnt components - these kinds of items come Dead on arrival all the time.

Which machine do you have?

To be frank, almost always it turns out to be an end user wiring matter. I don't think I've ever seen the electronics not register switch closure when the switches were wired right. I don't mean that to sound crass, I'm just speaking to what our experience is on it. Something isn't connected well perhaps.

Hey fellas thanks, I. Using bought the carve king. And derek you answer wasnt crass..... But I know for a absolute fact I have the connectors in the right order. I've tried different conectors as well. Keep in mind x switch was working fine buy now dosent... Hmmm any thoughts?

You want to make sure the connections are to the +Y, +X, and +Z (unless you are using a laser-spindle configuration) using the inside and outside pins along the edge of the CNC Shield.

Thanks bruce! Need to save this, was trying to look for it when i was trying (poorly) to describe it above haha!

It looks like these boards are about a year old. It is possible there has been a failure on them. If you right click the command line and turn on verbose output and short the pins that Bruce indicated with a small screwdriver, do you get PN:X or PN:Y or PN:Z at the end of the text scrolling across the screen?

Hey fellas, nice diagram Bruce. Yep definitely, definitely have the wiring correct, before starting this forum for help, I shorted out the wires at the circuit board. NOTHING....... BUT I do get the E.M STOP to work. Abort, and hold seem fine, I'm working on the homing switches first, so havent actually checked the coolant or spindle Spd. And so on. Tonight I'll get on the laptop and try out your last advise derek, I think I understan what you think I schould try. AWESOME HELP SO FAR GUYS THANKS! HOPE TO GET THIS SOLVED:)

Ignore the above post. Derek I did as you described above but I couldnt right the command line. I'm confused how to exactly get to a pin x and so on when the scrolling keeps throwing infinite idle codes. What I'm doing wrong?

Hey chris! When UGS is in verbose, it streams constantly (like you saw) however, when you hit any of the limit switches (or manually short their terminals) you will see the verbose stream report the event - usually a string quite a bit longer than the other text scrolling. This is what we are looking for here: Proof that the following is occurring: 1. The limit switches are not erroneously activating with the switches not being 'clicked' (remember we are connected to the NC terminals of the switches 2. that the board is actually seeing those switches 3. the board is notifying UGS when the switches are hit
