Good day all,

I am a student doing a design project on timing belt and pulley with design considerations.

I need to achieve a position accuracy of 1mm. Initially, i thought that a 1mm pitch will do the job, but apparenatly, the pitch and the position accuracy is two different issue. I am very confused of how to achieve it.

Do i need to find a smaller pitch size pulley? (I tried searching but to novalid.)

My current design
Given Centre Distance = 1500mm
Calculated Minimum Diameter of pulley = 3.074mm
Ideally Gear ratio: 1:1

Would apperciate if someone would give me some light about it. Thanks
