Set up YRR 3.0 using lightburn

LightBurn will call for homing in the Device Settings when the engraver first connects, if Auto-home on startup is selected.

After you shut off Auto-home on startup, click OK at the bottom of the window to write the change.

This was my guess because the machine position was all zeroes.

If that’s not the cause, Please zoom out to capture the whole work area (where the art is) and capture the screen and the Laser window. I’d just like to have a look at those settings because they can throw off framing.

Another thing to check would be the offset settings.
With the Ortur connected, In the Console window in LightBurn please type the following:
$#
then press enter.
