gShield v5 Synthetos
We are now selling the new v5 version of the gShield, formerly grblShield. Other than the price, there is very little difference between the v4 and the v5. Both can be used on the Arduino Uno to run grbl, or on the Arduino Due to run the TinyG Due port. The v5 power jumper simply allows the gShield to be run as a native 3.3v device from the Due, instead of a 5v device. There are no other functional differences.
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).
Interprets a subset of rs274/ngc standard gcode
Three motion control axes – X, Y and Z
Full support for arc motion
Acceleration / deceleration management
Compatible with grbl 0.6 and later versions
Three stepper motors supporting X, Y and Z axes
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
