After adding the Opt Laser to my Shapeoko XL I was struggling with finding a suitable source of a PWM signal on the control board to operate the laser. I think I have solved that problem. Now I need to turn my attention to getting it to work with LightBurn. Since I have only used LB a little, and I am not a native GRBL speaker, I thought I would turn here.
My Shapeoko XL has a 32"x16" work area. But the Laser has come thinking it is hooked up to a Shapeoko XXL with a 32"x33" work area. So, I have been trying to figure out how to set the machine parameters to recognize the area that it actually has to work in. In reality, since the laser is about 4" in front of the spindle, my work area really needs to be set to something like 32" by 12".
I tried editing my device (Device button -> Click on Shapeoko -> Edit -> Next -> Next -> Then setting the X Axis length to 815mm and the Y axis to 400mm. I also set $130=400 and $131=815.
Still, when I go to the back right position and click on “Get Position” in LightBurn, it returns 845 and 850.
When I click on some of the Move controls it attempts to move past the parameters, doesn’t seem to recognize the limit switches, and makes a racket. When I click on home it attempts to move to the left and crashes into the front of the machine looking for the extra 17" it thinks is there
What am I missing?
