The encoder does not play nicely… Sometimes it works nearly fine, sometimes it just does not do anything, or jumps randomly around.
So it seems the encoder is a 24 steps rotary encoder, should any brand work, if I’ll change it?
One local shop has 20 step pulse-encoders, does this sound close enough? I guess it would just work a little slower?
Sorry I’m one of those evil second hand users, who bough an unit somebody else made, and my electronics skills are quite weak.
Seems kinda strange. So are you saying some sessions it’s 100% fine and others not? Or does it work fine, then during a session go all wacko?
You might want to check the soldering before getting a new one.
IIRC, there’s also an acceleration curve that has caused some users to think their encoder was busted.
Sometimes it works better, most of the time barely at all. And, please, I know my inertia when I see it, this is just plain random behaviour. Good idea about the soldering, maybe the uni took a hit in the mail.
I had the same problem and in my case it was the firmware that was too old I did the update V2_043 and it works great, I hope it will help you solve your problem.

OK, I was using 2_040 before, and finally now have some time, I quit my job and moved to the countryside to a small cabin 
So today I finally plugged everything in again and took a look at this.
I just uploaded 043 and it seems that the encoder works fine, no inertia though, it always scans at a predefined speed. But better than jumping around 
Great, I’m off to write some tracks!
