Searched now for hours and can't find any amount of info on the use of timing belts to provide primary motion in the place of ballscrews or R&P. Unless I'm missing something belt drive should be the simple way to get precision motion.
R&P has gear mesh issues, dirt buildup, ballscrews need quality supports or live with backlash, with using a rolled screw you have lead error and then to get fast ipm's you have to consider critical speed. So it appears that a 1"
min width belt, Kevlar , with a few simple pulleys in alignment solves a lot of build and accuracy issues. Open for any comments. Specific application:50" square moving table router. Any links to existing threads, please insert.
Thanks
