Hello!
Help me, please.
Bought a laser machine LaserCut FO 3015-1.0PRFM, and there is not a single metal cutting mode. I want to cut steel 0,8; 1; 1,5; 2; 3; 4; 5 mm. Stainless steel 1; 1.5; 2; 3 mm; Brass 1; 2 mm; Aluminum 1; 1.5; 2; 3 mm;
Tell me the parameters that affect the quality of the cut and which ones can be changed, and which ones should not be better?
I know that stainless steel, aluminum and brass are adjusted to the bottom layer, tell me how to do it?

If I understand the number right, that's a serious Amada machine with a 1 kW laser, right? You should be able to cut mild steel to 12mm like butter, stainless to about 6mm. Steel needs oxygen as an assist gas to work.

Brass? Aluminium? Not really the sort of thing a CO2 laser will do, but you don't say what technology it is.

Talk to the company that sold it to you and get more details, you're obviously floundering in the dark here.
