##### Can Mach3 do continuous loops?
« on: June 22, 2012, 04:58:50 PM »
Hi all,

I'm starting to get to know the machine at a basic level.

Does anyone know if there's a gCode that can program the Mach3 to do continuous loops over and over again once i've put in a design layout?

Thanks,
V

Write a subrutine, and call it as many times as you wish.

THE sub DOES have a 99 loop max.

True continuous, M47 at the end of the code, Rewind and Restart. But it will run forever, you have to stop it.
I used it to verify a set-up, let it run for 48 hours with a small program.

TP, what about a sub in a sub ?  99 x 99 ? ? ?

or use a variable counter.

N10 #100 =1
N20 M98 O1 (RUN  SUB)
N30 IF [#100LT300] GOTO 20    (LOOPS SET TO 300 OR WHETEVER YOU NEED)
N40 M30

IN THE SUB INCREMENT COUNTER #100=[#100+1]
You can "chop it off" but can't "chop it on"

SORRY but mach3 does NOT have conditional Gcode.

What would happen with M47?

What would happen with M47?

"M47- Repeat program from first line"
It would loop continuously ..... until you defaulted on your electric bill.

Thanks guys!
Only one thing though, when I put the subroutine in microsoft notepad and save it as .tap/AllFiles... it doesn't show up as a subroutine on my Program Run scroll box and doesn't perform the function because essentially there isn't one.
Help?
