I use a program called lightburn for my CO2/diode lasers. One feature that I use alot is the frame button. This basically runs the nozzle around what you are cutting in a square to make sure you have room on the material to cut that particular item. I noticed linuxcnc has a extents display on screen giving the location of the start as well as the length/width. I know I missed this feature as I was cutting some items and missed the plate on the one

Interesting. Normally I just look at the preview window and jog the torch around the extents of the program's movements (white/grey lines) and then jog the torch down at each critical point and make sure it will have enough material to eat.

Seems to work well. Though it's not automated like you're saying.

Take this for example, the yellow is my jog path prior to running the program:

Pretty sure this was discussed here before, but my google-foo if failing me !

Also pretty sure there was some kind of solution, most probably python checking the extents in the gcode file and generating the test pattern.

I have seen that request before but forgot about it...

So there is no Z motion, just a rapid to X/Y start point then X/Y motion in a rectangle around extents at current material speed?

I dont want to speak for OP, but it might be useful to just do it at cut height?

Maybe just treat it like a dry run, but instead of dry running the gcode, it just dry runs a rectangle around the program extents?

I would not, it will bump the torch to the material, very bad material here.
For what is worth, i have 5 Euro (very expensive, i know) "cross" laser pointers on all new machines, makes life much easier.

How do you do a dry run then?

I think I might get one of those lasers soon. Phill has a pretty nifty touchoff tool now that's native to QtPlasmaC. Seems pretty useful.

I wonder if the 'gcode properties' info is useful for that - you could use the info to build a macro to rapid around the perimeter...

I just watch the laser while jogging manually, leaving the torch up.
