I just wanted to put in my little story on this (and a few other) threads about stuck wheels. This morning, someone reported that the push button on one of our Ultimakers wouldn't turn or click. So I start tearing the thing apart, and finally get to the point where I'm going to try and knock the white knob off from the hole in the back. It won't budge, so I give a few taps with a hammer on the allen wrench I'm using to push it - and half the rotary encoder rips off the circuit board! Why was it not spinning or clicking? Because someone who'd put on some ABS juice let it dribble down over the rotating part, and it wicked in between the clear and white plastics - and glued it together. So if it won't click AND it won't spin, make sure you haven't had something like this happen!
