ServoBelt goes Semicon (again)

This is a set of ServoBelt stages stacked to be an XY for a semiconductor application.  This video is just a burn-in move. The critical move of 12mm can be done in 180msec, settled to 5um.  Payload is 34 lb.  Motors are Teknic NEMA34 4-stack on the bottom and NEMA23 4-stack on the top, with Teknic Eclipse 350R amplifiers, and Renishaw RGH41 linear encoders.
