Ah. That's about 5 tpi. 495 oz-in sounds kind of inflated for a size 23 motor. What kind of driver (who's brand) and current setting? Micro-stepping? How many micro-steps per step? I realize that you're getting rid of it but for others who wish to retrofit your knowledge and experience is priceless. Thanks John
