Mach3 Showing Emergency Triggered

It's likely to be electro-magnetic noise, have you tried setting the debounce timing to a much higher setting?

Try 1000, if that's still problematic try 2000, then 3000 and 4000.
Something else worth trying is running the PC from a separate socket as far from the machine as possible via an extension lead, don't ask why but this does work, I swapped the mains feed to the 1hp VFD on my little CNC mill to a socket 5m away and it eliminated the noise issues,

I had this, or a similar problem, where the Estop was triggered randomly with a 'Driver Watchdog' error. I found a setting in General Config which sorted it. To the best of my recollection it was 'Use Watchdogs', which when ticked cured the fault.

What error message do you get when the Estop is activated ?
