Ultimake2 LCD stops responding or starting up

Recommended Posts


I got issue with Ultimaker 2 LCD not starting up on powerup, I need to turn it of and on couple of times for it to start up.

And, sometimes on long prints LCD just freezes up, scroll wheel is not giving any sound when clicked. The printer continues to print but sometimes fails to properly end. That is, the buildplate does not lower and head does not move to 0 position.

Any ideas ?

And another useful hint - The Ultimaker 2 assembly manual:



@illuminarti: I think this manual, the UMO assembly guide and Robert's visual guide should be pinned somewhere prominent on the forum frontpage. What do you think?

Does the button still work - if you rotate it and click it, does it beep, as if clicking on (invisible) things on the screen?

The next thing I would check is that the tiny ribbon cable from the screen to the ulticontroller board behind it is connected properly.

The assembly guide that nicolinux linked to above will help with that. Take the electronics board off carefully, and slide the screen out. Then check that the ribbon cable is inserted evenly into the the retaining clip; the bar on the front of the socket slides out parallel to the board, towards the edge of the board: grip the ends of the bar with you finger nail to slide it out.

It sounds like there is a problem with your screen and/or ulticontroller board. The earlier problems make me think it might be more than just the screen, but perhaps when the screen was failing it was shorting something out and upsetting the rest of the functionality.

I'd recommend you put in a ticket at support.ultimaker.com, and paste a link to this thread.

    • "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.
