    Hello,

    This a very useful article, I am also looking to ad a fourth extruder to my rumba board, but I already have the EXP3 pin 6 used for the BLtouch, is there any way to connect the expansion board to another pin? or does it has to be a PWM capable pin?

    Thanks

    Thanks for this! You have two .h files in this. Replacing the content in the original .h files with your attachment is throwing a "macro "lcd_implementation_drawmenu_back" passed 4 arguments, but takes just 3" error :/ . And this is for all the MENU_BACK functions. How can I fix this?
