Cindy,
I'm not a micro-manager expert, but have had some recent experience in
interfacing a position control device (a.k.a. stage) with it using an
arduino, so may be of help to you:

uM knows about stages, and is able to control x-y coordinates natively.
If you forget about one dimension, it may be just ok to use x as a
rotation magnitude. Then you could use the acquisition manager to do
snaps at different angles. Stiching them is another issue.

Stepper control leverages CNC code. There are various codes that could
be used and in general implement a positioning/acting control language
called gCode. Micromanager has native support (RAMPS) for a Sprinter
controler. I tweeked GRBL (which fits in an arduino UNO) to be
recognized by the RAMPS driver in uM.

Look for info in the mailing list archives.
