This CNC laser machine is built with open-source hardware and software. It uses a diode laser for cutting or engraving, controlled via G-code from an ESP32-based controller.
Laser Cutting Operation
- ✅ Budget-friendly and beginner-friendly
- ✅ Uses GRBL firmware and ESP32 controller board
- ✅ Designed for wood, acrylic, and light materials
- ✅ Expandable and modifiable frame
- ✅ Compatible with LaserGRBL, UGS, etc.
- Connect MKS-DLC32 with MKS-TS35.
- Plug MKS TMC2209 drivers with heat sinks.
- Wire motors to the X, Y and Z axis outputs.
- Connect the diode laser (PWM spindle).
- Connect external 12V power supply for motors and laser.
- Flash GRBL to ESP32.
- Use LaserGRBL or Universal Gcode Sender to send commands.
- Configure GRBL parameters for motion and laser PWM.
