(OP)
I wanted to know if anyone has ever cut precoated steel on a laser. I am planning on trying this I wanted to know if anyone has tried this and what were the results how does the edge end up was there any damage to the machine.
Also I have herad mixed views about etching aluminum has anyone on here tried it and what kind of results did you get and was there any damage to the machine
thanks in advance

The cut edge was always clean and burr-free. Welding performance of duplex cut edges suggests that there is a heat affected zone, but it's not detectable to the naked eye.
We had part numbers laser-etched on the parts. It had to be done on a separate low powered machine, because the photon cannon used for cutting perforated the parts at character corners.
I understand that at least some optical parts are treated as consumables, because of destruction by laser energy. I'd guess the same parts would be affected by metal fumes or paint fumes from the stuff being cut. Not my machine, not my problem.

Not much different from bare metal. Buy it with pvc coating to protect the sheet. Etching Aluminum is not very good on a CO2 laser, I think YAG has a better wavelength for Aluminum. It will crack the focus lense. The beam forms a puddle which is very reflective in aluminum and copper, bouncing back up to the lense face and overheating it. At $700-$1500 a pop, it's not much fun.
