FW8S-STXL motor stops

There isn't really much that can happen inside the camera to affect the operation of the wheel. The power comes into the camera, goes through a filter and a protection diode (0.3V drop), and then goes directly to the filter wheel connector. That leaves more than ample power for the filter wheel. If the input filter or protection diode were to somehow fail, the camera wouldn't work either.

Although it is uncommon, there could be some minor mechanical issue. Too much or too little belt tension can cause issues - though I don't recommend adjusting this yourself. The carousel bearing could possibly have an issue (especially if disassembled and reassembled incorrectly - there's a very specific assembly order to the various parts).

If you want to purchase another wheel, we do have three units left. We aren't making this model anymore so we have reduced the price.
