Hi Thank you very much for your willingness to help. I know a few people who are interested in this option. And others will be eager, I guess. For maximum speed of the LPT port, maximum rotations of 1000 cpr encoder is only about 500 r / min, and it is certainly not enough. Pluto-P is the least expensive of the faster solutions.
