In a very informative post on microstepping last May, Mariss ended with a summary statement that you should "stay away from 'square' 34s with more than 900 in-oz holding torque and you will do OK". Since I am (or was) considering 1290 oz-in motors from Homeshopcnc for a RF-45 bench mill conversion, his warning got my attention. Can anyone explain what the tradeoffs are... or point me to other sources? I assume the NEMA-34 geometry creates some sweet spots in motor perfomance. Illumination on this would be appreciated.  |
