can greyscale be used in a co2 40watt laser? If so, can anyone give me any info on how to do a photo from a camera, not a internet download photo.

Yes but not really recommended.
Having said that and after long fine tuning i was able to reach this outcome on my co2 K40
SKR 1.3 32bit 100mhz Controller. I don’t want to judge it too soon and before i will have a PC 1m away with a good USB cable. so far i am very happy.
This is an image i just downloaded from the internet and without changing any settings from my grayscale calibration image, this is what I’m getting (On a gray 2mm EskaBoard):

I am very pleased.

Thank you for your advice. I will try a download pic to see what my results might be.
Am I the only one that thinks Grayscale should be renamed to something like Depth?

Are you familiar with this technique?
Naming feature can be tricky…
[3d_laser_engraved_koi]
This koi scene and the grayscale test square below are my first attempt at 3D laser engraving. Both are 0.5" thick pieces of walnut. This circle is 3.5" in diameter. The max depth of the burn is 0.15". I burned it with LightBurn on a 100 W CO2 laser in a single ~40 min pass.
LightBurn Parameters:
Mode: Image
Speed: 150 mm/s
Max Power: 100%
Min Power: 19%
Bi-directional
scanning: On
Line Interval: 0.03 mm (847 DPI)
Image Mode: Grayscale

@Squid yes, I am. Why I think it should be renamed Depth. People see it and think it’s what they should use to engrave a grayscale photo when in reality they should be using one of the dithering strategies.

GrayScale looks amazing with Diode Lasers.
I am not saying no to depth, I am just saying it is tricky to name features. not an easy task.
True, I hadn’t considered diodes. Perhaps Variable Power then.
