How are you checking your pulley alignment? Are you using a straight edge, a lazer pointer or a wooden dowel? It's not as easy to do correctly as most people think, and close enough often isn't. What thickness belt are you using? Does it fill the entire v-groove of the pulley? Does it stick up beyond the groove?
Look closely at each pulley where the belt begins to contact the pulley. There are two places to check on each pulley. Does the belt touch one side of the pulley wall more than the other at these 6 locations?
More pictures of these locations would be helpful.
