A belt on the outside idea for Nema 23 motors

Post by northbear » Tue Jul 24, 2012 9:47 pm

I really liked the belt on the outside idea listed here (http://www.shapeoko.com/forum/viewtopic.php?f=11&t=436), but I am thinking of using nema 23 motors and since they use a 5mm bolt same as the idler pulleys I thought it would be cool to combine the two. So instead of using hex standoffs like the nema 17 belt on the outside, use two standoffs for the top bolts and (shown as mcmaster part # 94669A183) and for the bottom use a stack up of the idler pulleys and a couple of 5mm washers. Pictures below to better explain!

I really like this idea. I'm going to have to try it when I'm building my bigger shapeoko.
