I have a atezr L2 laser. I am facing a issue with lightburn.. specifixally, when i notice that i forgot something and hit the stop button, the laser loses its homing. Or vetter, the current position becomes the new 0/0. I have to re run homing to get the zero correct again. Problem with that is that it homes the z axis again and i have to set the focus again, and by doing that i often accidentally move the workpiece…
Is there a solution to this? Why is it loosing the 0/0 position when i press stop? (Not emergency button.. simple stop in software…)
Because the data is streamed to the laser. LightBurn can’t know which is the last command that has been in the transfer buffer and was executed by the laser.
First thing: you should optimize your workflow that you don’t need to stop. Why is that? I never needed to do so except in case of an accident (and then homing doesn’t matter usually ).
Using absolute coordinates is not required in most cases. Just use “current position”, position the laser where you need it and press start. The homing is not required at all.
STOP in the software is an emergency stop sent to the controller. Pause is what you use to retain position information, but it pauses the streaming and does not allow adjustments in the GCode program created.
This happens to all of us. Some people use the Checklist to help.
