Yes, that is normal. Encoder counters count every transition, so a 512
slot encoder is 2048ppr. But if you turn the spindle slowly you should
see them count up in ones.
How accurate is the 90 degree shift? Halscope might be able to tell
you at a slow steady speed (if the individual pins show up in
Halscope)
