Thanks in advance for any help.

In general everything works. If your commanded angle happens to be 0 then regardless of what your current angle is you skip the optimization. In the case of being optimized at 180 and then getting a 0 angle no rotation is required but due to the additional check it thinks a 180 degree rotation is required so it spins 180.

What problem were you trying to solve by adding the additional check?

I agree this appears to be the issue. Did you perhaps mean to specify speed!=0, so deal with the case where it just doesn't matter ?
