fault: external e-stop required

[rikduk]

Does anybody know what it means? Or fixes?
It happened a couple of times last week during cuts. Everything stops.
I just need to press reset and start a new piece, but its annoying

Thanks

forgot to say, i have my floating heat switch wired as a safety stop with shielded wire in place of the blue jumper wire in the bladerunner box, in case ohmic sensing fails.

sounds like E-Stop could be getting triggered - if you have an e-stop button it should be normally closed or wired closed if no button - or disabled as an input - if it is an open active input, depending on the breakout board, it might act like an antenna and trigger false signals - adding a debounce delay can help

the floating head should not be on e-stop, it should be a soft stop, so you can resume afterward

just guessing but it could be a combination of the above

All our Z axis home switches are normally closed with a machined hole for the wiring and are tucked behind a plate in a machined location for high frequency applications. Rikduk's applicaiton is high frequency so technically it could be EMF noise however it could also be a short in the Z home switch you setup for estop (if you set and estop) If not then it truely would be EMF noise. He is using a CandCNC Ohmic sensor which is technically not shielded against high frequency and is not reported to compatible.

Thanks for your answers,
looks like noise from the switch to me, im gonna check it out,
how do I put a "delay" to e-stop ?
And yes, I run candcnc ohmic sensing with high frequency, but I finally got it to work (a magnet was all it took)

I think debounce delay is in config/general-config at top right, mine is set at 4
