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. Set SWITCHING_NOZZLE_SERVO_ANGLES to 165 and 0. You will likely need to adjust this later on when fine tuning your setup.
    • Set SWITCHING_NOZZLE_SERVO_ANGLES to 165 and 0. You will likely 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. Configure the thermistors. For the low temperature thermistor (white cable) select 561. For the high temp thermistor (blue cable) select 562.
    • Configure the thermistors. For the low temperature thermistor (white cable) select 561. For the high temp thermistor (blue cable) select 562.

    • Make sure to also download both of these temp profiles and place them into your Marlin thermistors folder. Marlin/src/module/thermistor

    • The download is available here.

  5. For the low temp. side, set this to 275.
    • For the low temp. side, set this to 275.

    • For the high temp. side, set this to 450.

  6. If you are using the included extruders set the steps to 98.
    • If you are using the included extruders set the steps to 98.

    • Set retract acceleration to 3000.

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

    • 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.

  8. 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.
