TinyG Introduction

TinyG v6 Board

TinyG is a port of grbl to the Atmel xmega that runs on the TinyG hardware. Some differences are:

  • 6 axis motion (XYXABC axes)
  • jerk controlled motion for acceleration planning (3rd order motion planning)
  • status displays ('?' character)
  • XON/XOFF protocol over serial
  • config is necessarily different to take into account the larger number of settings

See these websites for more details.
