Introductions:
GT2 belts and pulleys compliant (GT2 pulley) are popular choices for RepRap tests and traps.
The series GT2 belts are specially designed for the linear movement. Use a profile with rounded teeth, which ensures that the belt tooth
perfectly and accurately into the pulley groove, so that if one reverses the direction of the pulley, there is no place for the band to move
in the groove.
For the best performance, which is at least six teeth in contact with the pulley at a given time. This minimizes the possibility of sliding ring and
helps to play in reducing even more. In practice, this means that you have made at least a pulley 12 teeth, and I usually try to get at least 16
teeth.
