Main encoder broke (the pot, not the knob) need new one

Posted · Main encoder broke (the pot, not the knob) need new one

My U2 encoder indicates it was made by Alps, but there is no model or part number on it. Does anyone know the part number for the main knob's encoder on the circuit board? I submitted a support ticket. Just posting here in case anyone knows.

While making a hinged door for my U2, I decided to take off the whole front panel to have an easier time attaching a magnet to keep the door closed. In doing so, taking off the front panel of the U2 box, I didn't notice that the shaft for the main knob's encoder was attached to the round semi-clear plastic housing that was bigger than the hole in the front panel. As a result, the shaft pulled right out of the encoder and the inner parts of the encoder went flying all over my table. My encoder is now a 1/2 of an encoder.

In the meantime, I figured out how the encoder works (pretty cool, actually) and temporarily connected momentary push switches on a breadboard. So I can move the display cursor around and increment/decrement values, albeit very slowly :)

Thank you for any help!

    Sure! If it's the same part/model number. I just got home and planned on posting pics of the current button hack I have in place in case anyone else needed a quick-n-dirty way to regain temporary control.

    Thank you, again, Illuminarti, for the used encoder! I look forward to receiving it.

    Here is a pic of my encoder button hack I have working at the moment:

    Ultimaker encoder button hack

    The first two buttons from the left control the cursor:

    Cursor up = push-right, push-left, release-right, release-left

    Cursor down = push-left, push-right, release-left, release-right

    The last button on the right is the select button

    Weird thing about the sequence is that for most menu items, those four actions = 1 cursor movement. For certain menus though, each button press/release of the sequence = 1 cursor movement. ie.changing temperature is faster because every 'click' moves the cursor.

    Short (blurry) video of the process. The slow button presses/releases don't work as well as the faster ones towards the end. The blue painter's tape over the two LEDs is to cut down on the sheer brightness when trying to sleep. Don't need it when the whole unit is put back together.

    I received a new circuit board from fbrc8.com (thank you!) and can put away my button hack! :) Was (sort of) fun while it lasted, but am SO much happier with the encoder!!!

    Hahaha, cool hack.

    Just for future reference. The part is a EC11B15242AE. And the schematics for the controller are at:

    Thanks, Daid! I ordered a few of those encoders to play around with for something else :)

    Hello can you post the diagram for the yellow wire's on the print board.

    The picture is not clear. I want to make a stop button for remote control the device.
