Who has the best 8M GT2 Profile cad file for making pulley.?
I saw some cad files on some sites(for example: SDP/SI), but when you open the file see 3d model profile is very different with GT profile patent.!
profile in patent have many arcs in one pitch but cad file has been drawn with max. four arcs.in one pitch,!?.then not complete conformity between poly chain GT belts with profile surface of pulley and occur backlash and noise and lower performance of drives system.
