So I’ve never seen this one before. I have 5 lenses, a 70, 112, 174, 200 and 300. The 112, 174, 200 and 300 all calibrate fine. I have the red light and laser aligned perfectly using a 20mm and 30mm square. After calibrating the 70mm lens and working on alignment, the laser burns a rectangle instead of the square (24.45mmx21.58mm). The only way I’ve been able to work around this is by adjusting the field offset, which i shouldn’t need to do. If I delete the lens from lightburn, reinstall it and burn a square it’s almost right on but once I run calibration again it goes back to a rectangle. Anyone have any idea why or how this is happening? Since it only happens with my 70mm lens I assume it is something in the settings but I can’t figure it out. Probably something simple that I’m overlooking.
Thanks
