Ultimaker 2 Knob Changes rotation (Unable to use correctly)

Recommended Posts

Posted · Ultimaker 2 Knob Changes rotation (Unable to use correctly)

Hello,

I built a 3d printer with Ultimaker 2 Hardware. But i have a problem. As you can see in the video, Controller Knob is changing rotation when using it. I think rotation changes at a certain point. Cant control the printer correctly. It's very hard to control in this situation. What i need to do to fix this problem?

Thank you.

Clearly you're having encoder issues, so the question is why? It could be several things, of course. The first and easiest thing to do is check the EXT2 cable from the main board to the controller board. Make sure it is properly seated and undamaged. Regardless of whether or not it looks alright, unplug the cable at both ends and reinsert. Maybe it helps, maybe not.

If not, I'm going to go out on a limb and say odds are you have a glitchy encoder on the controller board.

The encoder is produced by ALPS, type number EC11E15244B2. It might be a bit tricky to source at the moment, it appears... backorders are annoying.

Here are some sources for you anyway if you want to give that a shot:

RS P/N: 729-5555

Mouser P/N: 688-EC11B15242AE

Farnell P/N: 2064978

Does this apply also for the rotary encoder? I ask, because it looks like your encoder works with a different amount of steps per revolution than it should do...

Good point! Ultimaker 2 hardware is... subjective :)

I used "chinese" controller board, so that could be the issue. I think i need to change "rotary encoder" part. Thank you for the replies :)

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
