I have this issue that I have a complex vector with holes inside the figure and when the laser comes to those holes, it doesn’t turn off to not cut the inside, so its tiring and frustrating to make every single detail individually does anyone has a suggestion?
someone on the Lightburn forum has this problem and their GRBL based controller didn’t have $32=1
If you are using Lightburn and the GRBL-1.1e and older option fixes the problem then you either have an old firmware version or your settings are not set to use the firmware as a laser(that’s what $32=1 does).
I guess this is more a problem of the file you use. Can you upload the file here so I can check it?
To check if your hardware is acting correctly, you might just try this gcode:
This should create a rectangle with the bottom line cut with 100% (if max S is 1000), right line with 50%, top line fast move not cut and left line 100%. M4 only works with GRBL >= 1.1f and $32=1. Otherwise you have to use M3.
