Hi guys, I have a bp series II changing over to servos. the motors I am using are (servodisk jr16 x3) (nice snag) specs 3000 rpm 7.8 amps 168vdc 31"# torque should make a nice setup. Will start with the geckos I have then, switch to viper 200 drives. Looking for the best compromise between speed and resolution, should have enough power. need to order the right differantial encoder cpr for this setup to get the max i can. using mach3 and ncpod. stepdown ratio 2/1 or 3/1. tkanksĀ gary
