I would like to know if there is a way to perhaps import a STL of a curved surface, and have lightburn adjust the Z axis according to the model as it starts burning with the laser to keep the focal point at optimum height.
LightBurn does not work with 3D shapes. 2D vectors only.
Not yet, you mean.
is there a way to do it without a STL then?
Your best bet would probably be looking into the Z-Step Per Pass option in the layer settings. It would probably depend on how curved your surface is though. You’d have to do the top most layer, then move it down x mm and do the next layer, etc. But you’d want to make sure your laser nozzle doesn’t hit the work piece.
i have found a opensource software that will let me do it thanks a lot for the reply.
software is grblgru, looks to be able to handle what i need for now,
hopefully lightburn will be able to do STL’s pretty soon.
