Not sure yet if my first response will be posted, but besides the possible issue with the Belt changing places on the Pulley, another cause could be the possibility of your SAMA not remaining stationary?
I'm finding that out myself with a recent SAMA installation, that the stock rubber SAMA feet seem to be inadequate. My SAMA I note is beginning to pull towards the Platter, that I'm noting inconsistency of Belt Tension due to this "pull", I'm seeing the Rubber feet bend-lean under this pressure, and am in the process of retro-fitting my SAMA with a set of Herbies Tenderfeet.
They are a few mm taller, but a wider foot, at 1.1" x 1.1".
Other devices out there could be used. I think the important thing, will be providing a rock solid anchoring of the SAMA to whatever Shelf-Rack you use. Mark
