A particularly popular upgrade for the Ender 3 is a laser module. This allows you to engrave different materials like wood, metal, acrylic and many more. Depending on the individual performance it is also possible that wood and acrylic can even be cut.
This laser modules does not require any firmware upgrade as all you need to do is just use Creality workshop to generate the gcode and just run it normally.
