need to change direction of y axes. how
reading config of GRBL and applying it in machine configuration of LB
your target is $3
Use Lightburn ‘Edit → Machine Settings’. Change the required item. ‘Write’ it back to the controller.
Suggest you ‘save’ a copy of the original and ‘the fix’ configuration files.
Found problem it was build mistake and not a GRBL problem.
Thanks for response.
