I have to say,it is nice to be able to tell your machine how to run instead of having to learn to or get used to running a machine someone else has configured. I am sold on EMC.
In the original post on this thread, I proposed 2 buttons, one a Run/Step and the other a Pause/Resume. The controller I converted from had those 2 buttons close to an e-stop and until a program was proved out, 2 fingers stayed on them.
Thanks to John and Andy, I got my Pause/Resume button. I did a little work on my own and was able to get the Run/Step button (admittedly the far easier). So, for what it's worth, here is the program for both buttons:
# External Program Pause/Resume and Run/Step Buttons
# Pause/Resume Section
net pause-resume-btn and2.0.in0 and2.1.in0 <= hm2_5i20.0.gpio.027.in_not (this is your input)
net pause-on toggle2nist.0.is-on and2.0.in1 and2.3.in1 <= halui.program.is-paused
net run-on and2.1.in1 <= halui.program.is-running
net pause-sig or2.0.in0 <= and2.0.out
net resume-sig or2.0.in1 <= and2.1.out
net toggle-ok toggle.0.in <= or2.0.out
net togglesig toggle2nist.0.in <= toggle.0.out
net toggleon halui.program.pause <= toggle2nist.0.on
net toggleoff halui.program.resume <= toggle2nist.0.off
# Run/Step Section
net run-step-btn and2.2.in0 and2.3.in0 <= hm2_5i20.0.gpio.026.in_not (this is your input)
net idle-on and2.2.in1 <= halui.program.is-idle
# net pause.on and 2.3.in1 <= halui.program.is-paused
# and2.3.in1 was added in the net pause-on statement in Pause/Resume Section
net run-sig halui.mode.auto halui.program.run <= and2.2.out
net step-sig halui.program.step <= and2.3.out
This is how they function:
Pressing Run/Step will begin executing a program.
Pressing Hold/Resume while a program is running will pause the program.
Pressing Run/Step while a program is paused will single step the program.
Pressing Hold/Resume while a program is paused will return it to normal run mode.
I used this scheme ,but not always work correctly .
If use pause ,resume work ok .
When the program went to change tool
then something happens and no continues .
pause ,resume not work !?
I just added the above code. Works nice. Thanks for posting. I noticed in rigid tapping mode the pause didnt seem to work or only after a long delay?
No big deal as I don't plan on pausing during that op. I was just cutting air and trying it out.
I'd like to add a physical stop button besides the two above, is there a complete code example out there I can copy and paste into my config that includes the program stop button? Thanks!

How do I add the stop button? I found the example somewhere but can't find it again. Actually it would be nice to have the external stop button stop all motion in program run and mdi mode. I want to stop the spindle and the servos with a momentary push button.

I think I found the problem of run/step not working consistently. I have run the file and only one time it ran as expected and unfortunately I have not had it do again. I find that the pin "halui.program-is-paused" goes true when initially pausing, however after a step is made it toggles false which prevents the next step command from getting through the "and" gate. I don't know why it does this, but it looks like that is the problem.
I hope that sometime the file runs as it should and then I can check on what that pin is doing.

I'm pretty sure that if you have problems, it will be in your implementation. When I installed this example, it worked perfectly from the very beginning. Could one of the logic and2's be in use by another part of your hal file or something like that?
