If you have any CNC machine, you do not need much for a home CNC laser. A laser diode, a collimator, a laser driver, PSU (power supply unit) and cooling. There are some types of power sources. TTL, PWM (digital) and analog. The TTL CCS can only switch on and off, the analog can regulate the diode, i.e. turn it down or up. Laser engraver head based on a blue laser diode provides a rectangular beam and need an optic correcting it. At the small distance, you have when engraving, that's probably less interesting. Cheap lasers do not have this correction and are less precise. Also, they have a shorter life... It is definitely worth testing different materials to see which are better to cut by using several passes when you do not want to burn them instead of one transition. Especially when engraving wood it is a very wide subject. You can do it with a lot of power and quickly and with low power and slowly, with a smaller or bigger laser point you can get a lot of different effects and you..
