This project is a 450 nm, 10 W diode laser cutter and engraver controlled by a BTT Rodent board running the FluidNC firmware.
I made this project as I wanted to learn how to design a small laser CNC to cut and engrave plywood. I also wanted to learn how to use the FluidNC firmware, as in the future I'd like to design a desktop CNC router, and I wanted to use the same firmware and board for it.
- Laser PWM control
- 10W diode laser
- 24V PSU
- Web interface for controlling the laser
