I recently updated LightBurn to version 2.1 on my setup with a Thunder Laser Nova 51. Prior to the update, the camera functioned normally, but the update reset my camera settings. While attempting to recalibrate and realign my newly purchased LightBurn 120W camera, I encountered two distinct issues. …

The next button only appears when the calibration quality is over 0% That fish image does not look calibrated to me. The bottom of edge of the image still has some lens distortion. All straight lines should be perfectly straight. The alignment will be off if you just use the precalibrated camera ca…

after you calibrated, do you see in the cut/layer window support and material thickness fields? I do not on my xtool S1. [image] Lightburn 2.1 missing Support(mm) and Material (mm) fields in Cut/Layer Panel Cameras https://forum.lightburnsoftware.com/t/light…

Only for devices where either the Support or Material height fields are available in the Cuts / Layers panel, will the alignment wizard give you the option to define those on the Burn Alignement Pattern page. This is a fairly new feature. We are aiming to add support for more devices in future. […

@gabriel1 Hello Gabriel - so at this time, it is not supported for the xtool S1? Jeremy said to reachout if I do not have it in my cut/layer panel.

Thank you - I appreciate the response..

Thank you for the quick response and the suggestions on improving the calibration quality. I will definitely re-run the lens calibration process following your advice to hold the target closer, cover more of the image area, and introduce different angles to ensure the model can calculate the straigh…

I re-ran the lens calibration process multiple times following your recommendations. I held the calibration card much closer to the lens, ensured it filled a significant portion of the frame at various points, and captured images at multiple different tilt angles relative to the camera plane. Unfor…

I didn’t use the pre-calibrated camera setting for by LB purchased camera and I am still significantly off. x wanted → 78.02 / x actual =-> 87.2 y wanted → 121.907 / y actual => 107.65 The black was the intended target area, the red is where I landed. I’ve gone through this process twice. The fi…

I recommend using the Extended Calibration Model. The fish eye and standard calibration models will probably be depricated or upgraded soon. Gathering calibration data does require some time and effort atm. In the images above the calibration target does still look very small. It should occupy at l…
