I use a laser on my CNC router. I disassemble the spindle and mount the laser. In this case, a certain offset appears on the laser, which I measured and added to the device setting. Everything is fine when I go to the offset engraving works flawlessly. When I try framing, I have the exact offset that I added in the device setting instead of matching the spindle.

      No. That offset is not meant for this use case. The offset in device settings is used with a pointer laser that is on a different position than the laser. So the pointer is used for framing and then the laser is used for the job.
If your laser is at a different position than the mill, it doesn’t matter, and you can just ignore it. Use current position to start the laser job where the head is. Do not use the absolute coordinates as you might use with your CNC.

          : My CNC is 320x254 mm . Center of the machine is on 160x127mm. When i use offset in LightBurn (X -3.00; Y 1.30) with laser i can engrave perfect circle in the middle of my table using center as current position and that is exactly what i want. What is puzzeling me when i press FRAMING to check the center, laser is displaced for that offset.

          : That’s weird because this offset should not change the position of the output. Are we talking about this function? This is only used to make LB aware that there is a laser pointer at a different position than the laser itself.

          : I tried to explain that this is the idea of this offset-function. In case you set an offset here, LB things you want to use the laser pointer for framing. Therefore, you should turn off “laser on when framing”. Because you don’t use the laser to frame, but the pointer. LB uses the pointer (at its offset position) to show where it will laser in reality, and then go back and use the laser to do the job. So finally, this option is ONLY to create an offset while framing, not while running the job. The only difference is that the workspace is reduced, since the offset-distance is missing from the usable workspace.
