Help with G-code

[esawyja]

Hi all,
I cut polystyrene cornices, but how can I modify the G code so that when it is done, it starts at the beginning of the code again and just repeat. At the moment, I would cut one cornice, then REF ALL HOME and start again, so what I want is as follow

REF ALL HOME
My G-code for the cornice
Goto REF ALL HOME

I know the G code for rewind, but my main problem is the G code for REF ALL HOME. In this way I can start a cut and just keep on doing it till I have enough, or maybe put some kind of counter in the code, so if I want to make 10 cornices, I can set the counter to stop at 10? See the machine at http://www.poly-cor.com see the CNC page

I use AutoCad to design the cornice, export to DXF, load in DeskCNC to generate the G code and then control the machine with MACH3 (Quantum)

Please help

Problem with the code is that I do not want to move from the position where the cutter stopped after the 1st cornice, I just want to REF ALL HOME and then start cutting the new cornice, so that will take care of the spacing etc
Thanks
