My experience with steppers is limited, but the small NEMA 23s are quite nice, however the bigger NEMA23s became noticeably more "sluggish" which rather counted against the increased torque as far as performance was concerned. I can imagine that the big stepper motors continue this trend, and get stronger but more ponderous. Having built a stepper machine initially I decided on a servo machine for the second build, and have so far not regretted it. Just the repeatability of index-homing is a big plus to me. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Get your SQL database under version control now!
