Hello everyone, I just bought my first laser engraver, an AtomStack s20 pro rev.2, I built a box around it that is 300 high (interior height), the camera will be fixed under the cover.
I would like to know which camera to put in it, 2,4,6,8 megapixel?
What angle?
Autofocus or not?
If you have any advice to give me on the choice, I am a taker, I plan to go through the Chinese sites or Amazon.
Thank you very much and happy engraving.

Does it have a standard workspace of around 400x400mm? Then 300mm height is very low. For optimal results, you should have about 400mm camera height above the workpiece level at this workspace size.
Anyhow: choose a camera with an angle that just covers the workspace, not more. Everything seen beside the workspace is wasting resolution. Use as many megapixels as you can get, this increases resolution (though keep an eye on the computing power of your host PC). No autofocus. So, you need to measure and get the specs yourself, then select a camera.

thanks, an angle of 120° seems good according to the lightburn table, on this forum it says autofocus works better
Like this one.

There is no need for autofocus and it is only one more option to complicate the use of camera under LB. The focus needs to be adjusted once for the material you want to work with and it is done together/parallel with calibration of the system. Be aware that when changing material height, also the focus distance of the setup changes, you need a new customized profile again.
PS. Make sure a very stable static assembly of your camera, it must always be 100% in the same position otherwise you will get a bad result.

Check the physical sensor size: the larger the better.
A smaller sensor will result in higher pixel density which leads to increased pixel noise.
I’ve often seen 8Mp “HD” camera which gives 8 000 000 blurry pixels…

So wich one? 5mp manual focus?
8Mp is okay if the sensor is bigger than the 5 Mp
read the specifications of the models and look for a sensor value in inches or a diagonal in mm

Merci beaucoup
I bought a second hand Mintion Lasercamera! It’s very good: I can also use the wifi and drive from my room the laser in the garage next to it.
…and then the old discussion comes up again 
LightBurn, the fire department, insurance companies and many of us scaredy-cats, who may have even tried to set fire to their machines, are not in favor of this way of working with a laser machine.
But, we (most of us), live in a free world.

Nope. My computer is only a door apart from my laser: hence I protect my vision and my lungths. Feel free to sue Mintion.
the Lightburn camera specifications are:
-
1/4" sensor for 5Mp LightBurn Camera – LightBurn Software
-
? sensor (no information) for 8 Mp 8MP LightBurn Camera (4K-W) – LightBurn Software (sold out)
Thanks but too expensive and I don’t plan on moving away from the burner which risks catching fire
Pas de caméra disponibles,depuis un moment
Hello, you are right, it is too dangerous and too expensive too. I found an 8MP autofocus module that can be disabled and at worst I can change the lens.
AFAICT from a similar laptop camera in my heap, it does not have an M12 lens mount, so that lens assortment will not work.

If you can get it for a fair price it is ok, I think, and if you have calculated correctly on the angle/height then it is not needed to change the lens.
But, there is no guarantee that LB will “recognize” the whole 8MP of your camera, it will be fine if there is someone with this camera will come up with his experience.
I have tried a few years ago with a similar camera from one of the many Chinese sides and was not satisfied. It ends up getting me one from Lightburn.

There are m12 and m8 supports for this type of camera, they cost 1 euro max.
