Comparable in price to ball screw? My a**!... If your still reading this thread and are interested in RPS, expect to shell out about $3500/per axis (36" axis, 700-900ipm, 2500/lb expected max dynamic load)... and that price is before before you get into all the little things (mounting brackets etc.) Building a decent scale 3-axis machine with this system, expect to spend $12,000 (roughly my whole budget for this project) in power transmission...
What a joke... On the bright side they say its good for 30million hits lol...
Well, I just figured if anybody else bumped into this thread I might save you some time...
