Has anyone of you added new function to your Marlin firmware?
I’m willing to add one click function to lower buildplate in PREPARE_MENU.

from my understanding I have to define txt message in ‘language_en.h’ and add Gcode function in ultralcd.cpp

I’m using Marlin 1.1.8 with Rambo mini board and full graphic smart controller

my draft for adding this function:

language_en.h

#ifndef MSG_LOWER_B_PLATE
#define MSG_LOWER_B_PLATE UxGT(“Lower buildplate”)
#endif
________
ultralcd.cpp

  • “Prepare” submenu items
    //LOWER BUILDPLATE 100mm
    MENU ITEM(gcode, MSG_LOWER_B_PLATE, PSTR(“G1 Z100”))

I’m receiving error “‘MSG_LOWER_B_PLATE’ was not declared in this scope”

Solved. I defined MSG_LOWER_B_PLATE in non main section.
Copied it in different place and and compiled just fine.

And it works as well.
