Homing offset for origin vs homing location

I was wondering how to create an offset for the homing process, I’m swapping a Mach3 controlled 60w laser over to grblhal (Grbl1.1f) on a teensy powered board. the factory home switch location is in the back right location but 0 origin I work off of is the front left. In Mach3 there was an offset number you could enter after it found home to call 0, I’m not finding that option, or maybe it’s called something different does anyone have any ideas?


With grbl you can determine where and how you home.

Make that set to the way you want it to work, then tell Lightburn how you configured it, and it will replicate what you have configured.

You shouldn’t need an offset.
