Camera calibration problem-rotary enabled error message

I’m having an issue calibrating my camera. Hopefully, someone has seen this issue and has some suggestions on how to fix it. I’m using a Lightburn 120 degree 5MP fisheye camera on a Chinese 60W laser. The computer it’s connected to is using Windows 8.1 and the version of Lightburn is 0.9.16.

The camera will allow the lens calibration but when I start to do the camera alignment, Lightburn gives an error saying Rotary Mode Is Enabled. I have not set up a rotary and the tick box in the rotary setup dialog shows that it is off. Lightburn will not burn the test pattern while this error is there. If I select to have Lightburn disable the rotary I get a message saying Disabling Rotary Mode Did Not Work. Anyone have suggestions on how to fix this?

It doesn’t look like the 320A supports rotary settings in hardware. I’ve added code to manage this correctly, so it doesn’t report that the rotary is enabled either - it will be in the next release.

Thank you for replying. My issue was a sensor issue. This is a new laser and evidently one of the sensors was not making a good connection. I reconnected it and now the calibration is working now.

I am having the same issue when installing an new 140 Lightburn camera on my new China 100watt laser.

What sensor did you check?


I’s not a sensor issue, it’s a bug, and it’s been fixed.


Oz from Lightburn is right. There was a software bug that he fixed, but in my case I also had a sensor issue. When my laser arrived, two of the connectors were partially unplugged. One was the sensor on the door. (I traced the wire and unplugged and re-plugged the connector.) The second was one of the connectors from the control pad to the circuit board in the electronics cubby. I went through and made sure all the connections in the electronics cubby were good and tight even though it appeared that they were hot-glued in place. One was loose, which initially made my laser not able to fire.

I hope this helps.

Thanks for the info.
The patch fixed my issue!
