  1. Set the thermistors up as shown. Extruder HT is for a high temp side. Extruder LT is for a low temp side.

    • Set the thermistors up as shown. Extruder HT is for a high temp side. Extruder LT is for a low temp side.

    • Low temp thermistor (white cable, silver casing):

    • [thermistor Extruder LT] temperature1: 25 resistance1: 100000 temperature2: 72.5 resistance2: 12868 temperature3: 95 resistance3: 6854

    • High temp thermistor (white cable, brass casing):

    • [thermistor Extruder HT] temperature1: 20 resistance1: 4721000 temperature2: 200 resistance2: 8000 temperature3: 400 resistance3: 264

    • High temp thermistor (blue cable):

    • [thermistor Extruder LT] temperature1: 25 resistance1: 4500000 temperature2: 260 resistance2: 2240 temperature3: 460 resistance3: 125.4

    Edit

  2. Setup your config so you have two extruders.

    • Setup your config so you have two extruders.

    • Shown is just an example config, do not copy this exactly. You will need to edit these values based on your printer.

    • Set the thermistors based on whether you have installed a high/low temp setup or a high/high temp setup.

    Edit

  3. Create a section named [servo extruder]

    • Create a section named [servo extruder]

    • [servo extruder] pin: PE5 maximum_servo_angle: 180 minimum_pulse_width: 0.0004 maximum_pulse_width: 0.0024

    • Set the pin value to where you have plugged the servo signal line into your control board.

    • Create a section named [output_pin servo_power]

    • [output_pin servo_power] #Set low to power off servo pin: PE6 pwm: False

    • Similarly, set the pin value to where you have plugged your relays signal line into.

    Edit

  4. Set the probe up as shown, again setting the pin value based on where you've plugged the probe to your control board.

    • Set the probe up as shown, again setting the pin value based on where you've plugged the probe to your control board.

    • [probe] pin: PE4 z_offset: 0 x_offset: 39.5 y_offset: 32 samples: 2 sample_retract_dist: 3.0 samples_result: average

    Edit

  5. Copy the following macros into your macros.cfg file.
    Edit

  6. If you don't already have a variables.cfg file, create one and add the following code to it.
    Edit

  7. Finally, add to the top of your printer.cfg the following:

    • Finally, add to the top of your printer.cfg the following:

    • [save_variables] filename: ~/klipper_config/variables.cfg
