I have a laser engraver with only X and Y axis. When I click the “home” button the laser status changes to “Busy” and nothing happens, it just stays on busy.
I’ve wired my limit switches as normally closed. The machine works fine if I disable homing and limit switches but since I’ve installed them I would like to use them. Using the grbl status report i have verified that the limit switches change state when activated manually. In Lightburn’s Device Settings I have disabled the z-axis and I have tried all different combinations of GRBL settings but still no dice.
I know that grbl homes the Z-axis before the X and Y and I wonder if it is somehow waiting for the Z-axis limit signal before proceeding to the X and Y.
Any thoughts on how to resolve this is greatly appreciated.
