Cannot get it to work with an octopus v1.1

Hi,

I'm a newbie on marlin, I have followed the instructions on the English manual but the screen doesn't show anything, only the LED are On when I turn the motherboard on.

I have uncommented #define BTT_mini_12864 line in the config.h and that's it.

Is the guide un complete or something? I'll be happy to give you more information if you need.

Thanks in advance

If the display just lights up and shows nothing, try this: In the file: Marlin\src\lcd\dogm\marlinui_DOGM.cpp change parameter: void MarlinUI::_set_contrast() { u8g.setContrast(contrast); } change to: void MarlinUI::_set_contrast() { u8g.setContrast(255); }
