Which post processor are you using? Can you post a sample of your gcode showing a pierce?

Does your gcode have a pause coded in?

Yeah, I was just looking at your formula. Looks like it should work. I think that is a better idea than the cut distance at determining when to probe.

Cool.

Doesn't look the the formula is terribly complicated. Care to give it a try?

Proximity probing is an interesting concept. I guess it wouldn't be hard to implement. Simply note the x & y of a probe position and then calculate if the new pierce is outside of a circle centered on the previous probe position.
Probably makes more sense that cut distance.

Nope. It just helps to connect the posts together so people can follow all of the responses.

The 3 dots after the tool is just a shortcut to the tool settings. Same window you access from the toolbox on the main screen. The lead settings in the tool was a feature requested by me and some others, since these settings usually change depending on material thickness it made sense to tie them to...

Overcut should be in the operations settings. Not positive about the pause.
The lead in settings are also in the operations. I usually use a perpendicular lead and use the material thickness as a starting point for length.

You could add a short overcut, or add a short pause at end of cut to allow the flame to catch up with the torch before it shuts off.

If you have a THC, your torch could be climbing to get over the pierce dross on the end. Try adding a longer lead in to get your pierce away from the cut path.

I don't cut a lot, so I usually just manually set up the cut sequence and the part order.

Yeah, the round connector on the back is the cpc. It's for start, arc ok & the divided volts. The serial port is a long connector. It allows remote setting of the amps & air pressure and also error code readout. Your program would need that functionality to utilize it.

Does your cutter have a serial port? I'm guessing you have to set amps on the unit itself if it doesn't.
I have a Hypertherm and my controller has the ability to set amps through the serial port on the cutter.

It amazes me every day how a one man show is able to create such a robust piece of software like SheetCam. Kudos, Les.
