TinyG is a 6 axis motion control system designed for high-performance on small to mid-sized machines. Some features:

  • 6 axis motion (XYZABC axes)
  • jerk controlled motion for acceleration planning (3rd order motion planning)
  • status displays ('?' character)
  • XON/XOFF and RTS/CTS protocol over USB serial
  • RESTful interface using JSON

See these links for more details.

See the new TinyG G2 Arduino Due ARM Port and the G2 wiki

CURRENT MASTER VERSION The current master version is 0.97, BUILD 440.18 Please refer to the TinyG wiki for documentation and user manuals

IMPORTANT: If you are running a TinyG version 6 or earlier be sure to set the $hv value to 6 after you load version 0.95. Run $hv=6 and verify that it took. This addresses HW changes between the versions.

Tinyg versions 7 and 8 are electrically the same, and can be set to HW version 8.

The previous master version is 0.96, BUILD 380.08

======== BRANCHES

  • MASTER is the current production code. This is not updated very frequently.
  • EDGE branch is thought to be relatively stable, but has not received enough testing to be promoted to master.
  • DEV is work in process and generally not a good idea to use. Use code from dev only if specifically directed there. Build Status

The edge branch is the work-in-process for the next stable release. Depending on the velocity of changes it's somewhere between alpha and beta. An attempt is made to keep everything working and usable, but there are no guarantees. Generally speaking, the edge branch should not be used for production uses - use the master branch instead.
