Re: PWM vs Constant current and G-rex

2D and 3D can be visualized, anything above cannot or the
explaination is unsatisfying. With that in mind, let me try anyway:

4D: This may be silly but say you want to carve your name into a game-
winning baseball with a knife. The XYZ axis maps your signature on a
sphere (the ball). You want the knife edge to always point in the
direction of the XYZ travel using a theta (rotational) 4th axis.

5D: You are using a Dremel-like tool to carve a 3D bust (head and
shoulders) sculpture of yourself. For things to work right with the
tool you need to always keep it vertical to the carving surface
plane. The XYZ axis puts the tool in the required 3D space. The 4th
and 5th axis operate the azimuth and elevation of the tool. You get a
nicely carved sculpture.

6D: For some reason you have built the Hexapod you have always
wanted. Takes 6 coordinated axis to run it though.:-)

Whether it's 2D or 6D, all this means is 2 or more axis start and
stop at the same time while maintaining the same ratios of speed
between each other, each moving different distances.

P.S. The 5D carving thing sounds cool; I hadn't thought of that one
before.
