Mach refusing to detect an E-stop input
E-stop was working prior to a re-build and install and now is deciding not to work as required. Mach 3 is not detecting any inputs on pin 10 or pin 13 respective to how I have said pin input allocated.
I've got 5.5v between pin 4 and pin 10, then once I break the circuit via the e-stop It drops to 0v which shows it works fine.
This is the pin allocation within mach, I've got one side of the e-stop wired into ground and the other into pin 10 and set to active low.
Can anyone tell me am I looking at an issue within mach or a hardware issue.

Re: Mach refusing to detect an E-stop input
If you go to the Diagnostics screen in Mach3 activating estop should cause a port 1 pin to alter state and the Emergency indicator to come on. If that is so you are wired up and configured correctly. I have this BoB, but unfortunately I am not able to confirm P4 is the appropriate place to take 5v as it is installed in a control box which is not easily accessible. I believe that the p10 input floats to 5v and only needs a connection to, or disconnection from, GND to activate.
While I think about it, is the 12-24v power connected ?
If you need the BoB manual, you can download it here:- https://www.dropbox.com/s/gfq4isvihn...rd-EN.pdf?dl=0
Re: Mach refusing to detect an E-stop input
It's also no showing any detection on it. It's driving me mad as sure as I am it should be working and nothing is displaying/triggering. I'm going off past questions and what others have said to check regarding volt drops when triggered. Yeah everything has worked fine for months but I've just got round to sorting this E-stop issue out.

You have not answered Rob's question re the 12-24v on the bob also do you have the correct port set in Mach3. Should the e-stop be connected between grd and pin 10
Re: Mach refusing to detect an E-stop input
I did it's in there with the its been working fine. E stop is wired between ground and 10 as described above. It's set to port 1.

Well it seems you don't wan't to answer questions. No one has a crystal ball. re. "I've got 5.5v between pin 4 and pin 10," I don't think that is the correct place to get the 5v The inputs should show about 5V between a pin and ground. The reason for asking if the 12-24V is connected is that the inputs pins won't work without it.
Re: Mach refusing to detect an E-stop input
Well you directed at myself as you declared I've not answered my own question (Rob which is me), a little confusing. As I've said before I'm going off what others have declared to measure between on previous posts and yes the 24V is connected and into the correct pins.
Re: Mach refusing to detect an E-stop input
Hi RobC,
are any of the other inputs working ? Homes and limits that is.

Ok I am not prepared to get into mind games. Good luck
Re: Mach refusing to detect an E-stop input
Hello! Well I didn't rewire any in but I've just done so as an experiment and they trip the stop function no problem. So that got me thinking, I'll try wiring 24v straight across the E-stop and bypassing ground and that works fine so I've got that wired as such now to trip the E-stop.

It is a good job those BoBs are cheap.
Re: Mach refusing to detect an E-stop input
I ordered a second one as a means of maybe outright swapping this one, other than that I'ts not been too bad! I've had endless issues with mach and it doing random things like stalling on a G21 command making me restart the program to solve it. Now you've got me working on putting in my limit switches again as I've been working on where I knew it would crash and then making my work well within such limits.
Re: Mach refusing to detect an E-stop input
I'm endlessly amused by the things Mach3 "refuses to do" :D
Re: Mach refusing to detect an E-stop input
If I wasn't so broke with flying real planes I'd of long moved on from it, really fed up with the little issues I have with it!
Re: Mach refusing to detect an E-stop input
I use Mach3, all the issues I've ever had with it were about me, not about Mach3, which is the thrust of my comment :D
My new machine has a Siemens controller, Servos and Drives ;-)

I don't think that your problem is Mach3 but your own wiring or the configuration of Mach3.
Btw I stopped flying real planes about 10 years ago... but my CNC is working fine...:adoration:
