Ext-estop triggered ( please help )

[Valkyria]

Hello,
I have run into an issue that a lot of people are having, though none of the solutions have resolved my issue.
That being the ext- e stop triggered.

I have completely gone though my control box and check everything.
I have plugged All of my electronics into a power conditioner/surge protector/noise filter
I have grounded my machine and dust extraction directly.

When I pitched my machine it came with preset UCCNC settings that work with my machine
The Debounce was and is set to 50. Im not sure if that’s good or bad.

I’ve tried setting my estop pin and plug to 0.

And to no avail, I still get this after about 2 -3 hours of carving.
What else could it be ?
Please help

Try to disable all limit switches and the e-stop inputs in the configuration and see if it still happens if not then reenable them one by one to see which one is causing it.
