Dual extruder with RAMPS 1.4 and Marlin Help
September 10, 2015 10:45AM
I'm using RAMPS 1.4 with the last version of Marlin. If i set

#define EXTRUDERS 2

in the Firmware in the file Configuration.h i get the Error

temperature.cpp:1292: error: ‘DIO’ was not declared in this scope

when trying to compile.

Anyone knows how to solve this as i couldn't find anything via Google?

Ok i found a solution here.

I changed

#define MOTHERBOARD BOARD_RAMPS_13_EFB

to #define MOTHERBOARD BOARD_RAMPS_13_EEB.

Is there a significant difference between both?

EFB is Extruder, Fan, Bed on D8/D9/D10 . . . EEB is Extruder, Extruder, Bed . . . completing the definitions for the second extruder, and thus allowing a clean compile . . .
