connecting vacuum cleaner to mach 3
« on: March 30, 2009, 04:15:18 PM »
Hi guys,

I want to connect my vacuum cleaner to mach 3 so it turns on and off during running the program.  The only way is to do it via the mist/flood option? (not going to use this for wood :-)  Or is there a better way?

If yes, the code M7/8 and M9 I have to put in manually in lazycam or can that be done automatically?

When I check the option "coollant" in lazycam just before posting the g-code it just puts in the M9 in the beginning but never switch on the M7 or M8.

Thanks again for the help,
Cor

I believe when I used to use LCam, I had to modify the actual post processor found in the Mach 3 folder. Possibly someone else will be able to give you an easier fix but that's how I did it.

You could also modify the M3/M4/M5 macros to turn any output on and off to contrl the vacuum at the same time the spindle is turned on and off.  Then you wouldn't have to mess with the LazyCAM post.
