More guidance

• You are advised to install fans facing left, and pay attention to gears and air exhaust vents when installing fans facing right. 8 M3 screw holes of the extruder can be used to fix it.
• The m3*8 screws provided are suitable for mounting plates 3-Smm thick.

Maximum operating temperature

• Note: the maximum temperature is for individual parts, not the whole system.*
• Notice: The temperature of the extruder body will be slightly higher when H 2 500℃ extruder runs at high temperature in box printer. So to avoid scalding, please wear insulated gloves or contact the extruder after it cools down

Configuration

Hardware configuration

Driver and wiring
Driver: MAX31865 V2.0
MAX37 865 V2.0 can be used when the motherboard driver supports SPI mode Select 2-wire PT100 mode, choose ON for dipswitch 1, 2, 3 and OFF for 4.

Wiring
Please make sure the direction is correct when the driver is plugged into the motherboard(red-red, black-black) As shown when there is no color mark, plug the pin of the red part against “EN” pin on motherboard.

Firmware modification tutorial (Marlin bugfix-2.0.x July 07, 2021 version) The following is an example of nozzle 0 and the same is true for nozzle 1.

1. Configuration. h file

   • define TEMP SENSOR_O -5

   • define MAX31865_SENSOR_OHMS_O 100 // (0) Typically 100 or 1000 (PTlOO or PTlOOO)

   • define MAX31865_CALIBRATION_OHMS_0430 // (O) Typically 430 for Adafru it PTlOO; 4300 for Adafruit PT1000.

2. The configuration_adv. h file Configure the following options

   • define THERMOCOUPLE_MAX_ERRORS 20

   • define MAX_CONSECUTIVELOW TEMPERATURE_ERROR_ALLOWED 10

   • define SHOW TEMP ADC VALUES

   • define MllS_GEOMETRY_REPORT

3. PlN file configuration
4. Select the driver interface, and comment out the original driver definition to avoid interference. The above picture takes the BIQU BX motherboard as an example, select the El driver interface to connect to the max31865V2.0 module.
5. Define the SPI pin of the module

  * //Thermocouple sensor  

//if the TEMP SENSOR va lue of-5 is enabled in the configuration file, it will work

  * #define TEMP _O_MISO_PIN: PG3 //SDO
  * #define TEMP O SCK_PIN: PC7 //CLK
  * #define TEMP _O_MOSI_PIN: PC6 //SDI
  * #define TEMP _O_CS_PIN: PCS
3. Please note that the SPI pin needs to be consistent with the SPI pin used by the TMC driver.
4. Modify the maximum temperature

define HEATER_O_MAXTEMP 520 The maximum temperature exceeds 500°C
