Hello Raffaello,

I've sent you lots of Information and how to find more details here in the forum but never got any feedback from you. My questions on what you are planning and how to help you  have been ignored, too. So please re-read my messages, the threads in the forum and let us know the specific Problems.

The EQ changes i made have been described in the forum as well and I don't have any official documents on that topic. 

Regards
Andreas

---

There is no chance to measure the pulleys, when the motor
is in the Report.
I don´t want to remove the motor. Because there is only one
position, in which the motor is working.
Please take your IC-pulleys measures and convert them to
the size 38cm/s ...

Ok, thanks.
