When I use Lightburn software on my laser, I can load a job and click on a button called “Frame”. The laser head will move without firing and simulate a tight rectangle around the job. This is a very useful visual check for lining up the material to be cut. I can click the button and move the material around repeatedly until I get it exactly where I want it before starting. Is there a function like this in UCCNC for plasma cutting? I’d sure like to know how to do it. I know I can set up in SheetCam to use a corner or center. However, being able to quickly trace an outline with the torch head really would really help when I’m trying to fit a cut job between other previous cuts to maximize usage of an expensive sheet of metal.

Years back I did a macro that would travel the extents of the part in X/Y for a plasma cutter. It would always start at the minimum position of X/Y. I used it for exactly what you are needing. So it is possible.

Try this, it's likely one Terry started, and has been modified a few times over the years.

The last addition I made was to have it optionally go to 'center locations' along the sides instead of just the 4 corners, helpful such as if you have a round item. I haven't used it in a while.

You will want to check the FR for your feedrate, and the DT value for if you have UCCNC delay setup for mSec or Sec.

thats a handy one. will be adding it to my screen

Awesome. I’ll give it a try. Thanks Eric.

I created a button and added the macro to my run screen today. It works great. It’s exactly what I was looking for. Bada-Bing!
