GT2 timing belts and compatible pulleys(GT2 pulley) are popular choices for RepRaps and RepStraps.Designed specifically for linear motion.For best performance you want at least 6 teeth in contact with the pulley at any given time. That minimizes the chance of the belt slipping, and helps reduce backlash even further. In practice that means you want a minimum of a 12 teeth pulley, and I usually try to get at least 32 teeth.Size: Approx. 5 * 3 * 0.8cm/ 2 * 1.2 * 0.31 inch (L*W*H);Material: AlluminumPackage - GT2 Aluminum timing belt pulley x 5;Set Screw x 10;Allen Key x 1
I will likely end up doing the feet as well, but I also just did the dampers and had the heat shrunk on pulleys. It took only about an hour to do both the x and y axis motors.
Just tape up the motor real well. Several layers of protection that is. Keep every bit of metal dust and debris away from the bearings. There are magnetic fields in the motor and it will attract them. Use a Dremel with a cutoff wheel and cut the pulleys off. You might knick the shaft a bit, that's (somewhat) okay because you'll want to grind a small flat on the shaft for the grub screws on the new pulleys.

These pulleys worked great. I did a cube test print before and after and noticed not enough of a change to say it wasnt a print issue (maybe 0.005") difference. MAYBE...
All in all I'm very happy with the result. I will likely check the new gears to make sure they're staying tight and don't round off, this week sometime.
