I bought this laser from Bangood.com. and added few important improvements:
1) Vacuum plate with stainless steel working area (laser can’t damage it),
2) Under pressure regulator (achieved with fan speed control),
3) Fume blower (very important to achieve continuous clean cut),
4) Laser pointer positioning system (2 points alignment system).
