Hi All,
My absolute coordinates on the Lightburn screen do not match the actual bed placement of my workpiece.
I’m using an Atomstack S10 pro with an extended Y axis (Working Size X 410mm x Y 850mm ) I’m using a 170 degree fixed focus camera and have calibrated both the camera lens and the camera alignment (more than once)…
My procedure for using absolute coordinates is:
-
Place a work piece on the bed and focus the laser height
-
Home the machine (X=1 and Y=1. Never goes to ‘0’)
-
Update the bed background from the camera
-
Activate the positioning tool in the toolbar
-
Click on a corner of the workpiece
The laser head then moves to what Lightburn thinks are the coordinates of the corner of the work piece X=151 Y=436 (as displayed both on the lightburn grid and the get position display) but the laser is actually going to X= 196 Y=479 which is off by about 45mm for X and 51mm for Y
Any thoughts appreciated.
Thanks,
Jerry Kornbluth
FYI
I’ve checked and the machine is using absolute coordinates and the G54 value is ‘0’
