@gunnyb Customer used Lightburn ver 1.708 and there is no panning issue. When upgrading to any 2.0x version the camera automaictcally starts panning abck and fourth.
Laser is Xtool S1
Current setup:
Mac mini, Chip: apple M4
Memory 16GB
macOS: Sequoia 15.5
Camera mounted on top lid of laser
Here is a link to a video showing the propblem
Any ideas? This only occurs when gogn from 1.708 to 2.0x. Mac OSX photobooth works perfectly.
Brian
That’s interesting - I’ve never seen that with a S1, is that the stock camera?
Standard ELP 16mp 4k camera, I have used on 60+ other installations. I’m having him try changing the FPS settings, have no other idea, especially as the camer works fine with native apps.
Brian
Do you have a link to the camera specs? Things can get wonky if the lens is super fisheye.

Again I have had this used in other installations mac and windows - no issues, until 2.0.
Im hoping it is reolved, but wont know for a while. He chanegd to 10fps and the camera is not panning any more, but this may stil be a bug.
Brian
There it is.
Going to 180 degrees and beyond will cause issues like this. The math in openCV kinda breaks when this happens.
You may have had success before with different lenses that don’t cross that 180deg threshold, either by manufacturing tolerances being on the less-than side, or simply a lens that isn’t as rated on the box.
I have 67 installatiuons, and never had this issues, until verison 2.0
So far changing the fps to 10, is keeoping the camera steady.
Brian
While that may be, @JediJeremy can probably shed some more light on this, but as a rule of thumb, 180 degree-ish cameras will have poorer performance and may not calibrate at all. The camera system is going through major updates between 2.0 and 2.1 and I’d recommend moving to a lower fisheye lens for future installations - you’ll get better results anyhow.
due to the the bed size, anythign less than 180 did not work.
Then your next best option would be raising the camera mounting position, or opting for the head mounted camera.
LightBurn 2.1 also has support for IP cameras, and I suspect (like with the P2 and P2S) we’ll be able to pull in the camera streams from the xTool S1’s native cameras.
ok, the camera is mounted to the lid at the heighest point to get the whole bed . I hope they continue to work, as they worked flawless until this one instance for more than a year and a half, when i first started down this path.
Thank you
Briamn
xtool s1 does not have native cameras.
Found this on the site link you sent
fisheye lenses have different distortion modelling. For calibrating a fisheye camera, use opencv fisheye module. See opnecv docs.
I would love to beta test 2.1 when available
Thank you
Brian
I’ll send you a PM
Great - Thank you…
We’ve just replicated this in LightBurn 2.0.03 with the same camera module, and are investigating further.
Edit: It appears that this doesn’t occur when selecting a frame rate other than 1fps, so for the moment, the suggested workaround is to go to Edit > Settings > Camera tab > Set camera framerate to something other than 1fps
OKAY! Someone else with this problem!
yes, I can confirm that my workaround of choosing 10fps seems to have worked and fixed the jumping around. I have been using 2.0.03 w/o any issues with the camera jumping.
