When turning the encoder it feels stiff, like it’s grinding against something sometimes (it still moves through the data ok). Can’t understand why it started happening all of a sudden. Is it possible it’s been pushed down more than normal and grinding on the panel? Although I’ve never pushed it down, but one of my cats may have pushed it.
I haven’t tried pulling it up, thought I better check here first.
There’s a little screw on the side, undo that and the knob pops off, clean and re-seat!
Awesome, thank you for the advice!
Well, I couldn’t undo the screw…it doesn’t even look like a screw, just a metal hole. My eyesight isn’t too great though. Maybe the screw is missing? I tried to pull it but it wouldn’t budge…
Sorry, it was a bad choice of words on my part, it is a screw but it has a particularl kind of head that needs a precision wrench to undo, I can’t remember what it is offhand… a small hex key maybe?
Ah, same thing as an allen key I think then? Thanks Kel, I’ll try again tomorrow, I have some very small hex/allen keys I can try.
No worries, sorry I can’t remember the particular wrench I used. Perhaps use a magnifying glass or taking a photo with your phone so you can zoom in and see what you are doing?
I fixed it now. You were right, just needed a very small allen key which I had 
When I took off the knob, I noticed the nut underneath was loose, so I tightened that up and now it’s perfectly smooth again.
Thanks again for your support
Hi I have the same problem but when I tighten the nut it stops working completely, any recommendations?
