Lasercutter 2.0

Several upgrades for a K40 laser cutter:

• Designed, laser-cut & printed a new front panel
• Added an Arduino-powered LCD interface for precise power regulation
  • Rotating encoder knob to set power level in 1% increments
  • Default power level can be written to EEPROM
  • Integrated a water flow sensor: automatically shuts off laser in case of a cooling loop failure
  • Source code available on GitHub
• New internal controller: Makerbase MKS SBASE V1.3 32bit
  • Running Smoothieware, allowing us to use the awesome LightBurn software
  • Can additionally modulate power via PWM, enabling higher-resolution picture engravings
• Line lasers and a top-mounted camera allow easy positioning of work pieces
• Air assist: purges debris from the cutting site, allowing for cleaner and deeper cuts
