About a year ago, I made a linear stage for nanofabrication research use, with an integrated heated stage. It allows speed-controlled motion of a linear stage from about 1 to 100 microns/s, and heated bed adjustable in 1ºC increments.
It's presently being used by the Ullal research group at Rensselaer Polytechnic Institute. Details, photos, code, etc., on my site: rzach.me/slowpoke.html.
