Your extruder already present on your machine must be the same as the one on the ultimaker Bobinet. For this firmware, we have chosen the white extruder Ultimaker 2+ for its greater reliability than the black extruder present on the first generation.

We need to declare the second extruder in this firmware on the file Configuration.h:

// This defines the number of extruders
#ifndef EXTRUDERS
#define EXTRUDERS 2 // modif 6Maker 27 02 2017
#endif

This firmware allows the control of two white Ultimaker 2+ extruders " AXIS_STEPS_PER_UNIT {80.0,80.0,200,369}  ".

We need to declare the Axis step per unit in the file Configuration.h:

#define DEFAULT_AXIS_STEPS_PER_UNIT {80.0,80.0,200,369} // default steps per unit for ultimaker2 origine 282

Now, we must also define the meaning of these extruders:

#define INVERT_E0_DIR true // for direct drive extruder v9 set to true, for geared extruder set to false, Ajout 6Maker 2019 05 28
#define INVERT_E1_DIR true // for direct drive extruder v9 set to true, for geared extruder set to false, Ajout 6Maker 2019 05 28

You must have added the following items to complement those already present on your 3D printer:

  • A second temperature sensor identical to the one already present on your machine.

  • A second heating resistor identical to that already present on your machine.

    • A second olsson block to fix the probe N ° 2 and the resistance N ° 2
    • Now we need to declare the distance between this second Olsson Block for exemple 20 mm in x direction in this firmware.

// #define EXTRUDER_OFFSET_X {0.0, 20.00} // (in mm) for each extruder, offset of the hotend on the X axis
// #define EXTRUDER_OFFSET_Y {0.0, 0.00} // (in mm) for each extruder, offset of the hotend on the Y axis

  • And a second nozzle.

Here is an example of mounting with two nozzles on an ultimaker head 2:
