Bungard GRBL

Projekt: Bygge GRBL styring til Bungard CNC

Hardware

    • 220nF + 1kOhm mellem endstop pins og GND (filter)
    • 100 ohm modstand mellem M2 og 5V på stepper driver (quarter micro step)
    • VMOT jumper er pillet af (motors får 24V fra PSU, arduino 5V fra USB)
  • 4.2A, 24V Power Supply (motors)
  • DC-DC Step-Down converter (til FAN)
  • 1-channel relay module (spindel)
  • PC (LUbuntu/bCNC)
  • D-SUB 15 interface til Bungard motors og endstops
