I posted this topic over at lightburn, but figured I’d post it here as well, as I am trying to figure out the best practice for this little frustration I have.
I think maybe I’m getting way ahead of myself on my hopes for this but here is my plan.
I have a shapeoko 3 XXL with a Jtech attached. I ran a test using lightburn and all went fine after changing all the settings. However, because of the GRBL settings needing to be changed…well…that’s frustrating. I use CNCjs at the moment to send all the Gcode, and it has a laser module in it that works quite well. Since I can spit the GCode out of Lightburn and just run it from CNCjs without having to change all my settings then I want to do that.
To complicate things, as a long time CNC operator I would prefer to use G54 as my spindle offset, and G55 as my laser offset.
I’m told by lightburn I can not use a G55 command. I did manually change the code and it works fine when run through CNCjs. I’m wondering now, is there a way to tell either Lightburn, or CNCJS what the physical offset is on the laser for the SAME G54 work location. I generally use the same zero point in the front left of the bed located with a corner block for most of my work.
