2014-02-25 Delta Robot 3 firmware update

Delta Robot v3 has just been updated with tool offsets and tool changing.

Tool offset GCODE commands are G54 to G59. The basic system supports 6 tools at once.

[code]G28; home the machine
M114; report position. Z should be 4.77
G54 Z-2; adjusts position down 2cm
M114; Z now appears as 2.77[/code]

If you have more than one tool then it would be nice to have a way to have the machine remember the offsets for several tools at once. This update adds memory for all 6 tools. G54 will change tool 0, G59 changes tool 6, etc. M06 Tn will tell the delta that you have switched to tool n.

You can download the latest firmware from the delta3 open source repository on github.
