Hello dear friend. Im new to this forum, cnc machines and need help building my first one.

It should be made from steel and aluminium extrusion profiles, belt driven with working dimension of 2000 x1000mm.
Perfect solution would be x,y,z 3 axis + 4. axis for rotary engraving.

I have decided for LaserTree "80w" laser, they said it uses a prism to combine 2x Nichia NUBM0E laser diode. https://youtu.be/3gSazeplnm8
Optical power seems to be about 10w and it cuts 8.5mm plywood in one pass 100mm/min, later I would probably go for high power tube laser but think this one is best for now bacause of simplicity. of design and less trouble and parts,

It would be used for cutting thick wood, but also engraving photos so intensity should be also controlable.

For laser I decided, so there are all other parts left to choose best option for controller board, steppers..
It should be simple and good quality setup, thanks for your help in choosing the necessary parts.

* My question is what are the best parts to use according to the above requirements?
