Flickering in LCD

[droopas 0]

Has anyone experienced the content on the LCD jumping 1 pixel to the right every once in a while?

I have noticed while I use it that it occationally happens, perhaps once every minute or two ut only when servicing the printer.

I have the same behaviour it's kind of random for me, not sure if i have it on all my printers but my Ultimaker 2 has it for sure

Yes, I forgot to write it happens on UM2.

I've seen it do that on my UM2+ as well..

So it seems I am not alone about this.

Does anyone know what this is caused by?

- Electromagnetic interference? Bad connections? Bugs in firmware?

I seen it on mines running tinkergnome FW.

Had lcd glitching on my kossel printer.

Turn out to be a stepper motor wire to close to the lcd cables.

Its probably the same problem here

That must be why they started shipping new Ultimakers with ferrite cores. Hmm... Time to find some ferrite.
