Hi everyone,

I started to build my own laser engraving machine and I'm having trouble with a few things. I have power supply, laser tube, main board. How to connect them all?
I have this power supply. 40W Co2 Laser Tube Power Supply - Mini Laser Machine Power Source Special Model from China
Do I use this power supply only for laser tube or for both (laser tube and main board)? If I use it for both, when I connect laser tube for power supply and power suply to main board, do I need to connect laser tube for main board (and how)? Example, if I don't connect laser tube for main board, how will laser tube turn on (on my cnc machine I move z axis with step mottor->driver->main board, but on laser machine I will not have z axis, actually, I will use z axis for turn on/off laser tube.....but I don't know how to do that if laser tube is not connected to main board)?

Thanks in advance.
