ADDING a 3-Wire Laser to a CR-10S 3D Printer

I wanted BOTH a 3D Printer AND a Laser - in one device.

With minimal switcharoos necessary to go from one to the other.

So, I modified my wonderful Creality CR10S 3D printer (an Instructables prize!) by adding an inexpensive “5.5W” 3-wire laser. Today, I’ll show you how.


Mount a 3-wire laser on my CR-10S 3D printer
Control it via the incredible LightBurn software
Keep the CR10 still completely operable as a 3D printer without having to remove the laser.
Cut 1/8″ Baltic Birch plywood (even if it takes multiple passes)
