Some days ago I bought the LightBurn to work with K40 laser. I’m on my way to increase work size on my laser.
Here is my problem: how to start cutting from the top left corner? I set homing position to that point and whatever I do, the laser goes to 0,0 (bottom right) and moves further outside the machine, straight to collision with the frame.
I was looking on the forums to search how to work on negative coordinates with LightBurn. I was looking into docs for help (Documentation/CommonGrblSetups.md at master · LightBurnSoftware/Documentation · GitHub) but it does not exactly explain my setup.
Is it even possible to work with CNC Shield and LightBurn like on a standard K40 M2 Nano board?
