It is not obvious from your post, but have you tried changing the
blade? I am using the same saw and had a similar problem before
finding an ever so slight kink in the bandsaw blade that caused it to
jump on the wheel from time to time. I had virtually overhauled my
machine before figuring it out, but it probably needed a good cleaning
and alignment. After putting a new blade on, I was back in business.
