Macropede studies
Because I am working with a crude RepRap Printer outfitted with a 0.5 mm nozzle I will not be able to print Sho's fine design. Because I like the movement of the 16 legs per side, but can't print so fine, my Micropede will become a Macropede. Maybe after this studies I will be able to shrink everything in size - but at first this is not my goal...

Tonight I went further with the gear design which I explained already in an other thread. It has Module 1.5 gears.

The crank pins of diameter 4 mm will be direct printed on top of the gears.

The gear axis will be build by M3 screws. Yes this is a lot of iron but with 32 gear axis per side I don't want to be frustrated by one not well printed or broken axis.

This is my actual test setup with M3 screws as axis:

Because this should become a fine and nice running model I also like to have a quite and powerful motor. So I will try to use Sho's fine gear motors. I will power them with a circuit borrowed from a 3$ HobbyKing servo.

From left to right:
12 teeth Module 1 - will not use this fine Module
10 teeth Module 1.5
16 teeth Module 1.5
