UM2 screen burn

[sammo 0]

I have 3 UM2's and they are all showing some signs of screen burn - one of the screens has become unreadable now so have ordered a replacement. ( after 2 years printing, pretty much 24/7 )

Does anyone know of a Custom GCODE string I can include at the end of a print to switch the screen off?

It looks like M117 will display a message, I was wondering if I display a blank message if that would have the same effect?

The TinkerGnome firmware has a setting to turn off the display after an idle period (ie: no interaction with the printer)

Thanks for that, I'm a bit nervous about installing custom firmware - I've sent a message over to support at ultimaker - if it's not something that's supported at the moment, maybe it's something they could include in future firmware.

If you buy new screens now, how are the chances the printer will survive another set? 2 years?

Anyway, this is one of the main reasons i use tinkerware. + some other extras ;-)

In any case, it's an OLED screen so basically degradation is to be expected. Unfortunately it's a blue display and as such features the quickest degradation of all the OLED emitters.

At least on the Tinker firmware (not sure about stock, it's been a long time) you have the option to set the screen contrast, which gives you the possibility of reducing the brightness of the OLED and increasing the expected lifespan a great deal.
