Hmmm yeah that's about 300-800 reasons per ballscrew why to use belts instead! I'll be triple checking everything before each use anyway so it shouldn't be too bad. I should have the gantry design/whole design finished tonight minus ballscrews so I can start figuring out all the math and what it needs to run as well as possible.
How many hours are people roughly getting out of belts? Also, is it best to run an idler/tension bearing with them rather than moving the motor?
Cheers for the info!
