grblShield

grblShield is a shield that plugs onto the Arduino development platform transforming it into a CNC controller using the grbl CNC firmware

Skills: CNC, Embedded C, Hardware

The Arduino grblShield is a complete hardware solution for Dank’s CNC motion control system called grbl.
Compatible with the Uno and other 328p versions of the Arduino development platform. (Note: grbl 0.6 is not compatible with 168-based Arduinos (nor will it ever be), and currently grbl does not support the Arduino Megas).

grbl Features:

  • Interprets a subset of rs274/ngc standard gcode
  • Three motion control axes – X, Y and Z
  • Full support for arc motion
  • Acceleration / deceleration management

grblShield Features:

  • Compatible with grbl 0.6 and later versions
  • Three stepper motors supporting X, Y and Z axes
  • 8x microstepping
  • 2.5 amps per winding (bipolar steppers)
  • 12v-30v motor voltage supported
  • Independent current control per axis
  • Motor connectors plug compatible with RepRap and Makerbot electronics
  • Uses TI DRV8818 stepper drivers

Purchasing grblShield:

Currently the grblShield is available from the Synthetos Webstore.
