General Mach Discussion / Re: Can you wire a proximity sensor directly to a motion control board like a pokeys

Craig, totally appreciate your help. I understand in theory, but the terminology is beyond me. I'm quite capable with electronics, but all the stuff you're talking about dealing with pull up, resistors, etc... confused me and always has. I should learn.

Here's the sensor I'm using https://www.amazon.com/gp/product/B073VFRCCX/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 will this work alone on my board or do I have to use some sort of resistor or combination of things?

I'll look up what an open collector is and the other terms and see if I can wrap my head around it.

Uh, thanks. I'm not really following all the technical jargon, but I get the gist. I messaged Pokeys tech support and linked the sensor I have and they said I can use it directly with the Pokeys57CNC board. Just hook both COM on the board to the VDC negative on the power supply and so forth. The sensor is using 12VDC, but the board has an on board pull up resistor. So I messaged them back to clarify whether i can use it without doing anything else. Haven't heard back but will when I do.

I'm going to use some proximity sensors for limit switches, they're NPN. Can I wire those directly to my Pokeys57CNC pins? I'm guessing I can't because it'll only provide a sinking signal to the pin and not act like a relay and have the board COM pass onto that pin?

So I'm guessing I have to wire the proximity sensor to a relay and then use that to bridge the COM to the pin?

LOL oops, didn't see that. I'll look through that. Thanks. I have that manual too and saw that section, then I guess it just slipped my mind. I'm losing it!!!

In what manual? In the mach 3 page 30-31, according to PDF numbering, doesn't say anything. A-1 Has description, but seem cryptic to me.

I guess I need to ask, the ARC on the Proma THC, is it an output going to mach or an input from mach.

Correct, but in the pokeys/mach 3 settings I don't know how to classify the item labeled ARC coming out of the Proma THC. I'm not sure of the function so I don't know what to tell mach it does.

THC is a function of the THC Proma Controller, but that controller has an ARC output that supposed to go to the Pokeys motion control board, I just need to know what I label that input so it can work correctly.

I'm using a Proma THC 150 and instructions had me wire ARC to an input pin on the Pokeys57CNC, but what Mach 3 function is it supposed to trigger?

Also what function do I use to turn on the torch? I have it wired I just don't know the function, there is a THC ON is that it?

Ok, but will that move both Y motors at the same time then make the trailing one continue until it hits it's own limit switch?
