Biesse Rover 336 retrofit 5i23-7i44-7i66 and 7i33TA

Hello,
thank you. But I need an exact value. I tried different ENCODER_SCALE values experimentally, but I get 1-2 mm error at 100mm feed. No matter how many values I try, even float values, I still get pretty big errors.

You would expect 2.4 mm error in 100mm if you had 1000 instead of 1024 (or vice-versa)

If _no_ number gives the right positions then there is something else wrong.
Slipping coupler?
