Hello … Good Morning
i have Question !
there any one already make CNC Laser With Co2
so he can help me to make One
because i made cnc laser with laser module but he is very weak …
thanks the best group 
Making a CO2 laser is expensive. What kind of budget do you have?
For laser about 200$ … or tell me how mush will cost
Don’t think it’s possible. Only the tube will cost that.
Search on eBay for K40 laser cutter
@Ariel_Yahni_UniKpty
What else i will need expect the tube … thanks for help
Tube, psu, lens, mirror, mirror holders, those would be the basics.
It’s cheaper to buy a K40 and grow up
@Ariel_Yahni_UniKpty
Ohh i will be expensive … 
so if i will use Laser module . which best module can i use to cut and engraving …
and i have laser 2.5w and its so weak can i upgrade the beam of it to over 5.5w or higher
Cut is solely a actual job for CO2 as it’s much more powerful. Diode I don’t fell are made for cut
@Ariel_Yahni_UniKpty
i understand
if so i can upgrade my laser just change beam … so i dont need to buy another module … ?!
Again. You.can use any diode module you.want but this are.not.meant for cutting at least in speed
@Ariel_Yahni_UniKpty
i know man … i men with upgrade to get better engraving … and if the life time of beam end i will change beam without buying another module right ?!
A beam will last. Upgrade will make stronger beam but no enough to cut or engrave very fast
@Ariel_Yahni_UniKpty
A beam stay work until 10.000 Hours Right ?!!
Or like u said it will last ?!
Yes , what’s your questions? What you want to engrave or cut and with what purpose?
i was need to cut wood about 3m or something to combin together to make home … tower something like that
Hobby or business? How many? How big?
business … i think Mush … and not big its small … if business will be fine then will be big i hope
Buy a K40 laser cutter. It should be about 300 USD. If it’s a business you could be loosing business buy trying to get what you have to work. Mind that cut a piece of 3mm ply with this laser can take seconds
But Size of work its too small i think right ?!
300x200 you said project is small
