Hey everyone, I’m desperate for help. I just can not get my camera alignment right. I have a Sculpfun Cam500, watched the video explaining the alignment, followed the instructions exactly, and at first, the alignment seemed alright. I was able to engrave a couple of things. Then I didn’t use the laser for a week, and the next time I turned it on, it was off! So I did the recalibration, it seemed alright, then a couple days passed, and it’s off again! During each calibration, for some reason, some of the corners were not accurately traceable. (I did the arrow check, placed some stuff in each corner/side/center, and there were always like 2 corners that were off). Please, help me with this, I would really need the camera to work, but somehow it just doesnt. On the second calibration I was so damn accurate too, I made sure that everything is placed exactly where the software wanted it, and it still didn’t work.
Currently, if I place something on the overlay, on the engraving it is off to the right a little.
Did you move the setup meanwhile? If you did the alignment procedure, the camera might not move a single millimeter in relation to the laser frame. Here is some more information:
Thanks for the answer and the link! No, the camera did not move a single millimeter, and yet the calibration is off. In fact, as I said, I can’t get it to be perfect in all edges in the first place. But then, a couple days later, everything is off to the side! Like, everything I engrave using the camera is off in a djrection by like half a centimeter.
In my case, it sometimes helped to switch the camera to another one and back to the original one (within LightBurn). Maybe LightBurn then reloads the calibration and it works better. But overall, I don’t use the camera function very much, I also found it quite unstable in continuous operation. But in the future, there will be a major update to that functionality, which might get over those issues…
