Hi, I use a ball screw, but if I decided to use a rack pinion system now.
Two accurate reasons
- Long spherical screws will easily cause resonance problems
- Step motors don't like fast turns. The ball screw 1 rev is only 5mm, but the GREAT TORQUE (1605 screws)
if you use an servo motor I would take a ball screw.
sorry for my english
