I trying to calibrate my 250X250 lens for my ComMarker Omni X. I was able to do the 70X70 and 150X150 with little problem but the 250X250 is not working out so well. The main problem is the location of the framing outline for the 9 point correction, it is way off in the front left corner of the platform instead of the center. I set it to create the recommended 220mm square but when I actually run it, the square is around 90mm, however it did draw it in the center. I went through the measurements anyway for the corrections even though the square is small. Since the square is so small, when I manually draw a 220mm square to check the scale the right and left sides are curved way in and the upper and low sides are bowed out slightly. It seems the 90mm square isn’t correcting as it should. I tried to manually adjust the bulge for the X axis but Lightburn won’t let me go lower than 0.8750, I have 0.9000 for the Y axis. I need to go lower than 0.8750 to get rid of the curved sides of the box.
Since I am new to this I am probably doing something wrong.
Thanks
