G4 & G54-G59 updated in all robots

Tormach ATC

The Stewart platform, Delta Robot, Makelangelo, and Arm3 have all been updated to correctly interpret the G4 dwell command.

All the robots mentioned now also have support for G54…G59 (tool offset) and M06 (tool change)*.  This means you can set up multiple tools of different size in advance, and swap them without having to rewrite all the gcode.

For example, say you have two different pens in the Delta Robot v3.  One sticks out 1cm and another sticks out 2cm.  without tool changes you would have to rewrite all the gcode when you change tools.  Instead now you can write

G54 Z-1;  // tool one sticks out 1cm
G55 Z-2;  // tool two sticks out 2cm
M06 T0;  // change to tool zero
G0 Z0;  // moves the pen tip to the "floor" without going through
G0 z3;  // back off
M06 T1;  // change to tool one
G0 Z0;  // moves the pen tip to the "floor" without going through
G0 z3;  // back off - this backs off a different amount because G55

All systems support 6 tools at once.  I would like to see someone figure out how to lift/lower many pens at once on the Makelangelo so this feature could allow multicolor drawings in a single pass.

* Makelangelo support is still being tested.

DIY 3D Printing a Slew Bearing

Printed this bearing to try and reduce number of parts and shave weight without breaking the bank.  Pretty good for a first try.  Right now I’m mostly getting ready for the Bay Area Maker Faire, then I’m going to put some bevelled gears in the wrist and move up to 5DOF.  There’s a lot of people asking for a 3D printer nozzle on this thing, so I’m going to get in the gear and see about making that happen over the summer.

Oh yeah, follow the link above to get the STL file and the Instructables link if you want to make your own.  Please tell your friends, skull, and comment.
