Introduction

This guide assumes that you are some what familiar with editing your firmware. The guide focuses on the latest Marlin firmware.

  1. Open the Configuration.h file.
    • Open the Configuration.h file.

    • Set extruder count to 2.

  2. Uncomment SWITCHING_NOZZLE
    • Uncomment SWITCHING_NOZZLE

    • Set SWITCHING_NOZZLE_SERVO_ANGLES to 175 and 10. You may need to adjust this later on when fine-tuning your setup.

  3. Set the nozzle offset for the switching hotends.
    • Set the nozzle offset for the switching hotends.

    • HOTEND_OFFSET_X { 0.0, 28.00 }

  4. Set the thermistors (OLD):
    • Set the thermistors (OLD):

    • Low temp (white cable) - set as 1

    • High temp (blue or white cable) - set as 66

    • Ignore 560 in the image.

    • NEW 2024 Thermistor:

    • As of 2024, both sides are high temp 300C sides with the same type of thermistor. If you received your kit in 2024 then set the thermistor value to 5

  5. Set z-probe for homing. Define nozzle/probe offset. {39.5, 32, 0}
    • Set z-probe for homing.

    • Define nozzle/probe offset.

    • {39.5, 32, 0}

    • Probe Pins:

    • As mentioned before, in the wiring diagram, the probe's black cable needs to be connected to a digital signal pin on your control board. You can set this pin number by entering the following into either your configurtion.h file or directly into your boards pins.h file.

    • In lib/src/pins/...your control board

    • Here, the Z_MIN_PROBE_PIN is pointing to pin 4.

  6. Similarly, in the wiring diagram, the servos orange cable needs to be connected to a digital signal pin on your control board. You can set this pin number by entering the following into either your configurtion.h file or directly into your boards pins.h file.
    • Similarly, in the wiring diagram, the servos orange cable needs to be connected to a digital signal pin on your control board. You can set this pin number by entering the following into either your configurtion.h file or directly into your boards pins.h file.

    • In lib/src/pins/...your control board

    • Here, the SERVO0_PIN is pointing to pin 5.

  7. Set NUM_SERVOS 1
    • Set NUM_SERVOS 1

    • Set servo delay to 300.

    • Make sure that DEACTIVATE_SERVOS_AFTER_MOVE is activated (has the two dashes in front of it removed).

    • Also activate EDITABLE_SERVO_ANGLES

Aiming for a solution of multicolour and support material. This could be achieved by building 2 'dual switch hot-ends' in the X-wagon. To avoid issues, I rather not position both 'active' hot-ends in a printing position, where the not printing hot-end is unpleasantly close to the printed layer.. Is it feasible to program the hot-end switch in such a way, that it will 'park' the inactive set in a half-way position? With my limited knowledge, the hardware should enable this. The logic is doable, but the translation to code is way beyond me. Does anyone have suggestions?
