Hi It sounds like your well on your way, I like the quality of pacific scientific steppers that you have (powermax) if your planning a mid sized machine 100oz.in range will almost be the mininum you would want to use, just remember that stepper motors have less torque as they speed up, you will get results with your motors, and becuase they are a nema23 frame, swapping them later for a higher torque model will be easy.
