Hello all,

Which parameter in Rambo firmware configuration will change active extruder motor port from E0 to E1? without other changes?
(If it is possible).

Look in "pins.h". Search for "301" to find the Rambo section:

Code: Select all

#if MOTHERBOARD == 301
#define KNOWN_BOARD
/*****************************************************************
* RAMBo Pin Assignments
******************************************************************

scroll down to find

Code: Select all

#define E0_STEP_PIN    34
#define E0_DIR_PIN     43
#define E0_ENABLE_PIN  26
#define E0_MS1_PIN     65
#define E0_MS2_PIN     66

#define E1_STEP_PIN    33
#define E1_DIR_PIN     42
#define E1_ENABLE_PIN  25
#define E1_MS1_PIN     63
#define E1_MS2_PIN     64

Change the labels to swap E0 and E1. Add a comment to remind yourself.

Code: Select all

// E0 and E1 swapped!
#define E1_STEP_PIN    34
#define E1_DIR_PIN     43
#define E1_ENABLE_PIN  26
#define E1_MS1_PIN     65
#define E1_MS2_PIN     66

#define E0_STEP_PIN    33
#define E0_DIR_PIN     42
#define E0_ENABLE_PIN  25
#define E0_MS1_PIN     63
#define E0_MS2_PIN     64
