Is it possible to disable ARC_OK and still have THC UP/DOWN working? was created by fernandosf
Or any ideas how to disable ARC_OK only for the first second after cut started.
I don't want the torch to remain on the same spot (burning surrounding materials of a thin plate) at all, but I do want THC to do it's magic (thin plate warps like hell).
Mode 2 here - my external THC only sends arc_ok after 0.3 secs (lower than this, LinuxCNC emits arc lost error).
Edit> Maybe, it would be possible to set external THC arc_ok_delay to zero and increase dbounce arc_ok to something like 50, not sure if it's a good idea.

Wait, wrong, why would you use arc on delay, it should be set to 0 on both sides. On the external one also.

Because of this
Edit> Actually, I should have said that I need to set 0.3s on my external THC, otherwise, LinuxCNC emits arc lost error.Mode 2 here - my external THC only sends arc_ok after 0.3 secs (lower than this, LinuxCNC emits arc lost error).

Set the external thc to 0, that is not negotiable if you want to avoid big holes. Then add just a bit debounce to arcok in LinuxCNC, just so it can pass the signal cleanly.
Adding delay to arcok will make that hole only bigger.
