Running Mach3 for laser cutting questions

[CNCadmin]

Ok here is what is working for me, I'm using the z to turn on and off the laser BUT I have one problem. When the file is done cutting and I hit the go to zero the laser turns on, of course I know why because it's Zing down to zero which turns the laser on.

How can I get the head to go to the home position after it's done cutting instead of just sitting there?

Add G0 X0 Y0 at the end of your g-code. You could also make a button on the screen with the code to do it. Don't ask me how, though.

That's the sames as the "goto zeros" in mach right? that's the problem in doing that the z move to zero which in moving in the down postion and that will turn the laser on which is what I don't want, I need it to just move to home with-out moving the z.

Don't put a Z in the line. Just G0 X0 Y0

What are you using to make g-code? You should be able to automatically add it to every file.

Paul I am pretty sure you can take care of this problem in screen designer by opening the 1024.set file and editing the go to z's button. Double click on that button and it should show you what is being called by the program. there may be more than one way to do this, knowing how Art makes this program as universal as possible.

Hi All,

I have mach 3 running a laser fine I use the spindle PWM output to vary the laser power this seems to work great. I also set the Mach to 2D mode. I think this may be your problem.



Please post comments on our forum if you need help as I'm only poping in here and may not reply. Thanks

Hi All,

Mach3--> Laser--->Vector is good
Laser---> Raster is bad

Good day, Mike Gaylor,

How do you configure the spindle PWM for laser output? What are the settings involved in tuning the PWM spindle? How does it tune the laser; by g-code or by manually pressing the buttons located in the spindle section? Thanks in advance =)
