I'm planing on building a cnc laser cutter for cutting black 5 mm foam board, and if possible some 2 mm plywood.
Right now im trying to figure out what parts do i need, mainly what laser diode do i need.
I know that most of you will suggest building a CO2 laser but that's wayyy out of my budget.
I was thinking of using the NDB7875 diode with G-2 lanses, do you think its enough for my needs? i dont mind making multiple passes
I have a printrbot simple metal 3D printer, so for now the plan is to attach the laser next to the hot-end (it had been done before) just for testing the laser on different materials.
