Status update.
Had no problems compiling the sprinter.pde file under Arduino 0022 package after I made some changes to the pins etc. Most of teh changes are identified in each of the header files. An extra thanks to Kliment, Caru and Tonokip for the documentation within the files in Github!!!
Had a positive connection with control through Repsnapper of one motor (I only hooked up one for initial test).
Had reading on the thermistors and voltage on the outputs. Motor moved without any problems.
