I've got the CNC and now would like to attach a laser to it. Has anyone reading this retrofitted a laser to their cnc and would you mind sharing what you learned?
I have the KK01 breakout board from cnc4you.

Laser module - what is a good quality unit to get? I will be using it to etch/burn wood. No deep cuts or anything simply surface layer stuff.

Control module/driver/PSU? What else would I need to get burning?

Many thanks.
