Subject: G Code Looping
Greetings,

Still working on my auto loaded machine, but having an issue. I was planning on having my G-Code loop back to the top once it gets to the end of my program. Something like.

N10     M100 (waitbit to make sure the auto loader is out of the machine)
N20   
N30     Body of CNC program
N40
N50     IF[M101] GOTO N10 (Check if auto loader selector switch is on, if so return to the top, of off rewind)
N60     M30 (Rewind)

In my attempts to do this, I cannot seem to get KMotionCNC to accept the goto command, or the IF statement. Are these available in KMotion, or do I need to do this in a C program?

Thanks,

Scott

Hi Scott,

The KMotionCNC Interpreter doesn't support IF/GOTO Conditionals.

A workaround of having an infinite loop is to make the code a subroutine and looping the subroutine a billion times.

To terminate based on an external input some C Code would be required.

TK

N50 M47 (Rewind and restart)

Will work

M30 is rewind and stop
M47 is go back to first line and continue.
