Add servo motherboard and update Marlin / Double extrusion


Recommended Posts

Posted · Add servo motherboard and update Marlin / Double extrusion

Hello everybody,

i would like to add a servo to my UM2 for double extruder but i don't know where can i plug it on my motherboard in order to manage it.

I tried to change the marlin sofware to use one extruder for two head and one servo to tilt from the first head to the second head (http://www.thingiverse.com/thing:673816/#files)

I changed this file like that :


#define MOTHERBOARD 72

// This defines the number of extruders


#define EXTRUDERS 2




#define TEMP_SENSOR_1 1 // 0

#define INVERT_E1_DIR true // false

#define NUM_SERVOS 1


else if(code_seen('T'))


tmp_extruder = code_value();

//Added for DEISS dual extruder

if(tmp_extruder == 0) {




delay (servopos_delay);



if(tmp_extruder == 1) {








if(tmp_extruder >= EXTRUDERS) {



#define E0_STEP_PIN 42

#define E0_DIR_PIN 43

#define E0_ENABLE_PIN 37

// the extruder 1 pins as the extruder 0.

#define E1_STEP_PIN 42

#define E1_DIR_PIN 43

#define E1_ENABLE_PIN 37

//i must define the "SERVO0" pin


#define SERVO0_PIN 11 // i used 11 but i don't know which pin i can use and where i can plug on my board



// end

PLease, could you help me?

Thank in advance!!!

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
