pulley help!
I'm developing a machine that uses pulleys. Using "XL" series belting, 3/8" thick, i have stepper motors with 1/4" shafts; and 30-tooth pulleys.
I made my own linear bearings, and they ride in aluminum-etrdude. (this design is actually a work in progress).
So, as the "kart" slides along the rail back and fourth, an idle pulley on one-side and the motor-drive pulley on the other. The rails are 36" long.
Sounds easy? yes?
Anyway. I'm finding that the motor locks up when I high higher speeds, or if I tighten the belt too much. I never worked with belts/pulleys before, the machine I made in the past is a cnc-router, that uses leadscrews.
I was wondering if anyone had any links, or tutorial links on designing a machine to use pulleys driving with long belts, thanks.
