currently i am testing what a manufacturer claims to be a NEMA 23 400step/rev 120 oz-in stepper. it is worse than my NEMA 17 42 oz-in sanyo. i have tried voltages ranging from 10- 26v and all current ranges up to 1.2A (the stepper is rated @ 0.4A 12V) ... im wondering if i missed anything. or its just my luck my first try at other motors and its a lousy motor factory?
my thinking about 400step/rev motors is that to achieve their rated torque, they have to go 1/2 the speed their normal 200step brothers. there is a torque curve speed thingy correlation. they MAY be better in terms of step/rev ... but i have yet to see accuracy (which i will try on this spooky unit soon).
TBH, i think you should go for torque and a motor that matches your driver/current/voltage
*edit* ... i think reserve 400steps/rev for a good extruder
ok tested, surprise surprise ... 400step/rev in this case (this model, and setup) works really well for very fine works, BUT VERY LOW SPEED usage. [youtu.be]
