Re: Compiler Errors please help

When Adding a dual extuder you will need to add the Steps as shown in this sample of my Dual Extruder Configuration

// X, Y, Z, E0, E1 [E2[, E3[, E4]]]]
#define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 400, 94.4962144, 94.4962144 }

// X, Y, Z, E0, E1 [E2[, E3[, E4]]]]
#define DEFAULT_MAX_FEEDRATE { 200, 200, 5, 25, 25 }

// X, Y, Z, E0, E1 [E2[, E3[, E4]]]]
#define DEFAULT_MAX_ACCELERATION { 3000, 3000, 100, 3000, 3000 }

I found a version of Marlin 1.1.5 already setup for Dual Extruder and simply added my settings to the configuration files.

One for BOARD_MKS_13

Could not find a Way to do it using my mother board It is Extruder, Fan, Bed should be Extruder, Extruder, Fan, Bed

BOARD_RAMPS_13_EFB

I believe it was Originally setup for a Dual Extruder CR 10

Like in this Older version of Marlin documentation here, Will post when I remember Where I found the Dual Extruder Firmware.
