[vacpress]

CamIam - that is good advice, except sometimes the Z axis remains problematic. i had trouble with it, so i made a 2-setscrew per-shaft motor coupler.. something I would recomend: get a drillpress! that was my first "machine tool" it helped me so much.. a drill press with a vise can do so much if its all you have! plus, it makes a milling bit into a spiral cutter, and a sanding disc into a small part "planer", and.. and.. other good thigns are a small disc\belt sander machine. i got the cheapo ryobi of both these and am very happy with them for my purposes - acrylic, aluminum, delrin, etc.
