I have spent like an hour searching and maybe I am just not using the proper terminology.  I would love to hit a button and have my CNC trace out either the square box of the entire job OR the outside perimeter of the job.  Sometimes I am using a piece of scrap and would much rather just check it quickly then using the jog controls to move all over the place.

Does this exist?  Is this something a macro script would do?  I use this function on my laser cutter ALL the time and it has saved me from making mistakes as it's quick to check.

Thanks!

This is one of those things that may or may not work with YOUR version of Mach3. If it does NOT let me know and I will work on it with you.

This code will work as a button script you will have to setup your Work 0,0 and safe Z height the Feedrate is set in the script.

SetVar(120,30)  'SetFeedrate
SetVar(100,Getoemdro(4))
Sleep(100)
SetVar(101,Getoemdro(10))
Sleep(100)
Setvar(110,Getoemdro(5))
Sleep(100)
Setvar(111,Getoemdro(11))
Sleep(100)

Thanks for the code examples!  I will try this out soon, and see how it works.  I have Mach3 and Mach4 and I have used Lua before so if I get Mach4 working for me, I'll probably try and figure out if I can convert it.
