Um2 display knob rotation slowness


Recommended Posts

Posted · Um2 display knob rotation slowness

After reading many forums i have yet to find one for this...

The knob used by the display rotates and depresses but the display of change is very slow. For example, as I watch the temp selection and rotation of the knob it can take 4-5 rotations to go up 10 degrees.

Worse is when I attempt to level the bed and use the knob to raise the bed. Each rotation moves it up only about 2mm. Then it drops at the end of each rotation by about 1mm. This mean that it can take almost 30+ rotations before it reaches the top.

I have not yet reseated the knob and can not tell if it is mechanical or not.

Thanks for any assistance possible.

    Which printer are we talking about here? Regardless the answer to that, it sounds like you have a defective encoder on your controller. Start by unplugging and replugging all the cables to the controller, just in case you're lucky. If you're not I'm going with encoder failure.

    So you removed it and when you turn the metal thingy in which you push the knob it does the same?

    You can push the button out from inside of the printer, there's a hole where you can push a screwdriver to pop it out (assuming you are using an Ultimaker 2/2+/3)

    Heh, now I've just noted it says UM2 in the topic header. That means the encoder would be this one. If you're missing steps when turning it (should be easy enough to notice when navigating the menus) and your interconnect cables are okay, then overwhelming odds point towards a glitchy rotary encoder.
