Re: Where to put the "resolution"? Pulleys, motors, drivers.. ?
I'm running some 65 oz in 2.0A 400 step motors (KL17H248-20-4A) in my heavy old LXD650 mount. They seem to run just fine on LV2987s at .60 vref (1.2A). They actually ran fine at 1.0A, but I upped the current because I run some heavy imaging rigs, and the drivers are still cool to the touch. They didnt get warm until 1.3-1.4 amp, and then get smoking hot very quickly, so be careful. The drivers may have reduced life running at 1.2A, but they're cheap, and I have extras on hand. So far I have not had any problems pushing them hard, and the mount guides very well when conditions permit.
I also tried some S109s thinking they would handle the higher current better. I found them to be jittery and noisy no matter where the vref was set. I was not impressed at all, and very quickly returned to the LV8729s.
If you have the stuff ordered already, why not give it a try? IMO the LV8729s are cheap enough not to worry about if you cant use 'em.
