I just got my plasma table running, Mach3 and Lazycam where pre-installed and I know that Mach3 is a licensed version through my table manufacturer.
Issue I'm having is with offsets, Under the tool button the button which should say Create Offset(I believe that's what it says?)  actually says Pro Demo. No G-code.

I was under the impression that I had a licensed copy, but I'm assuming not?  Just want to make sure so I can sort out getting a license if I need one.

click "help" and then "about mach3 cnc controller" what does it say in "licensed to" box.

Licensed to Precision Machine.  They are the guys that build my table.

They may have supplied you with a license for Mach but they did not give you a license for the Pro version of LazyCam.
That's why it says Pro Demo and you can't do offsets, lathe, plasma and few other things without the specific Lazycam license.

That's what I needed to know.  Thanks Rich.
