Another plasma component...

Yes John is right, You need to base your distance calculation from the last probe event as that is the last time we know the height was accurate.

You may wish to consider using the last IHS point for your distance origin rather than the end of the previous cut. Your method assumes an accurate height at the end of the previous cut.

Thanks guys, yes I was assuming that the last cut height would be accurate.
I see in the Hypertherm ArcGlide manual (p159) that they do it this way but disable it if THC was not active or Sample Voltage mode was inactive. Which I forgot to do...
So which way to go, or make it user selectable or am I trying to do too much here...

Edit:
THC Enabled and Sample Voltage problem has been fixed.

I think you have to work with the probe event or when motion.spindle-on goes true.

I think when I did this, I started with a needs_probe pin that was true when it needs to probe on power up. Once probed, I turned it off and only enabled it when it was > the skip probe distance. That made the pin independent of any plasma cutting.

By connecting the output to a motion digital pin, M66 Pnn L0 (wait on input immediate) would return the state in #5399 so you could branch to the probe routine or not in gcode but you can do that in the component.

Guys

My method isn't as nice. I just do it with the PP and whether the probing subroutine is called or not in the Gcode.

So many ways to skin the plasma cat

Is there install instructions? I want to try and implement this on this machine I am building.
