As far as accuracy goes, that's based on the microstepping accuracy of your drivers and the pitch of the screws. The Keling drivers have a lot of microstepping options. If you chose to use 10:1 microstepping, that gives you 200 base steps/in * 10 microsteps * 2 TPI = 4000 steps/inch, or .00025" potential resolution. There has been some discussion on the true accuracy of microstepping, but let's assume that it works as advertised. This is far more precision than necessary for woodworking applications.
