UCCNC 1.1027 Works but 1.2113/6 don't

[ryana14]

So others can benefit I'm moving my report from e-mail.

1.1027 works perfectly for me, I can run G-code with no issues.
With 1.2113/6 I can jog the machine, I can home it. I can't run g-code though, not even one line, I immediately get ext. e-stop triggered. If I reset I can still jog and home the machine but even a one line X1 gcode will not work.
I have tried this on four computers. Three DELL laptops from 1 to 10 years old with built in gpu's and a 3 year old gaming PC with a Nvidia graphics card. I have installed the most appropriate graphics drivers on all. I have disabled all power savings and have set UCCNC to use 100% of resources.

I have two videos to show the issue:
1. 1.1027 jogging, homing and then running a simple few lines of Gcode. Works well.

2. 1.2116 jogging, homing, then attempting to run the simple Gcode twice, then jogging and homing again (successfully) then trying just one line of Gcode. Any Gcode fails with ext. e-stop triggered. No Gcode works. The resource monitor does not show anything of note.

As I said I have tried this on four computers so I doubt it can be my computer set-up. Any help to resolve this would be appreciated. I would be happy to run a debug version of the code to try to help figure this out.

Try to disable the e-stop input and the limit inputs in the configuration to see if it resolves the issue.
If it does then your e-stop input or limit inputs getting noise spikes.
You can then try to add some debounce using the debounce filter setting in the UCCNC configuration, it filters/mutes the inputs for the set amount of milliseconds.

Thanks for the reply. I have tried that. I disabled the e-stop pins as one test, I also disabled all limits as well. No change. I also tried hardwiring the e-stop so it was always on, also no change. What puzzles me is that 1.1027 works fine so that rules out noise.
As far as I know there is no debounce for the UC100. Sorry forgot to mention I was using UC100.
