Getting alignment on rotation is fairly easy. Take this beautiful box for example! 
Start AND end the first turn table sequence with the SAME face of the object facing the camera with a couple of shots past 0 to ensure overlap. Then, with the table at the original starting point, flip the object 90 degrees and shoot another complete 360 series.
I usually shoot 3 sequences. One original object orientation, one rotated 90, and one rotated 180. Always start the next sequence with the turn table at 0 with the original rotated object face toward the camera. I think this makes for easier alignment between rotations. Generally 50-70 photos per series (150-200 total) gives decent results I’ve done quiet a few objects like this and seldom have any alignment issues using a white featureless background and white featureless turn table cover.
Also, be careful with zoom. The more detail the better but too much zoom can cause depth of field blurring and negatively effect texture and possibly alignment. Sorry for the crappy artwork!
