Pick and place machine

Hello, guys. Anybody have full working prototype of pick and place machine, just wondering about gearing, tolerance and speed, power ratings. Thanks

I have one. I would recommend a 60mm circumference pulley, and the D5065 motor if on 24V power, and the D6374 if on 48V supply.

D5065 seems like it would already way more powerful than steppers. Would there be real need for D6374 motor?
