We just bought a set of plans for the cad cut machine. They come with a parts list, but being on a budget we are shopping around for stepper motors. Any advice on which brands to look for or stay away from. Also how do you determine compatibility with the software as well as the hole spacing on the plans. I realize that you can change the holes in the aluminum, but I want to know if there is a standard by which they are measured. I work with 3 phase industrial motors and they use frame sizing. For example any motor with a 184t frame is interchangeable as far as the physical properties (shaft size, height, etc..). Is there a way to determine this on stepper motors. The cad cut plans call for 470 in/oz motors from Micro Kinetics, I would like to know if I could substitute these motors

in there place. If the physical dimensions are not the same I could modify the mounting plate, but would they be compatible with the software the other steppers use? Are these good motors for a great price or cheap motors, and how do you tell? BTW the software in the plans is Indexer LPT from Ability Systems.
