Post by hdv » Wed Jan 06, 2021 4:07 am

Hi, I have an unknown LCD2004 display and controllboard.
I don't know what kind of type I should select under Marlin. I allready tried some without success.
Can anybody identify this board by the pictures?
thx

OK, I found a similar problem here, so I ground off the noses of the connectors and put the cables in the bases front to back.
Then the display works as a normal LCD 2004 and also the controller works.
>>> I just recognised that it only works, if there is a I2C Interface connected to the dispaly. I wonder why - but ist works this way.
