I would think that by the time the voltage was stable enough you would be cutting air again or maybe even the next piece of metal depending on feed rate. I don't think it would work for a sampled voltage , maybe OK for using material cut voltage.
So RAR = CPA
Yes, I htink what it means is that an arcOK will be returned instantly the torch passes over material. You would have to do some plots to see what the torch voltage does to see if it is possible to spot the THC height.

It would be interesting to repeat my kerf crossing tests in mesh mode and compare the difference in arc voltage behaviour between the two modes.

I'm kinda thinking that if someone wants to cut mesh they need to ensure it stay flat.
I don't think anyone can assume material being plasma cut stays flat
It doesn't seem to move much here:

if you forget.
Me, forget... Never!![]()
Me either
Mesh Mode and Ignore Arc OK are now as we discussed (or at least my interpretation of that) on 2.8, master and your branch
Man, you're efficient... Thanks!
The user guide looked good too. I am a bit curious, about this:
will begin a cut without requiring an Arc OK signal and also ignores a lost Arc OK signal during a cut
Is that determined by the placement of the M## P1, or is it something different... For instance
M62 P1
M3
Motion G-Code
M5
M63 P1
^would ignore Ok-to-move on startup
M3
Some motion
M62 P1
Some more Motion
M5
M63 P1
^would ignore Ok-to-move after the arc is started and motion is under way, until the end of the cut
Correct?

It didnt move much at all. In later cuts, I erred on the side of leaving the torch height pretty high, and slowing the feed rate WAY down. Where the video showed me cutting upwards of 300ipm, when I cut the second piece I was around 95ipm. It severed MUCH cleaner, and the torch being up higher seemed to be enough to keep the torch from bumping into the material.It doesn't seem to move much here:
I would think everything is happening too fast to get an accurate read on the torch height... but I suppose I don't know what I don't know either. Maybe it is possible. At the moment, I'm happy we have made it this far!

Yes, and also the type of commandIs that determined by the placement of the M## P1
No, M62 is synchronised so wouldn't happen until the "Motion G-Code" began, between the M62P1 and M3 you should have your G0 rapid move to position to sync to.M62 P1
M3
Motion G-Code
M5
M63 P1
^would ignore Ok-to-move on startup
M3
Some motion
M62 P1
Some more Motion
M5
M63 P1
^would ignore Ok-to-move after the arc is started and motion is under way, until the end of the cut
Yes, but to be safe you should use M65 at the end as there is no motion to sync to or use M63 P1 and have a G0 rapid move to sync to.

Watched it 4 times, it is mesmerising !
I think it was one of those things that I was so impressed that it worked exactly how I was expecting it to the first time, paired with it sounding like a metal cutting machine gun, either way, every time I watch it, it makes me laugh

I would expect that maybe it is possible on some machines cutting some type of mesh but I think there will be too many variables to be consistent.

It is definitely entertaining...
