ຄໍາແນະນໍາການດໍາເນີນງານ

The BIGTREETECH Pi V1.2 and SKR Mini E3 V3.0 are designed to run Klipper firmware, offering advanced control and high-speed printing capabilities. After successful installation, you will need to configure Klipper for your specific printer model and setup.

Klipper Firmware:

Klipper is a 3D printer firmware that runs on a Raspberry Pi (or compatible board like the BTT Pi) and communicates with the 3D printer's microcontroller (like the SKR Mini E3 V3.0). This setup offloads complex calculations to the more powerful Pi, allowing for faster and more precise movements.

• ການຕັ້ງຄ່າ: Refer to the official Klipper documentation for detailed instructions on installing and configuring Klipper firmware. This typically involves flashing the SKR Mini E3 V3.0 with Klipper firmware and setting up the configuration files on the BTT Pi.
• Web ການໂຕ້ຕອບ: Klipper is typically controlled via a web interface (e.g., Mainsail or Fluidd) accessible from any device on your network.
• ການພິມ: Once configured, you can upload G-code files ກັບ web interface and start prints. Monitor your prints and adjust settings as needed through the interface.

ບໍາລຸງຮັກສາ

Regular maintenance ensures the longevity and optimal performance of your BIGTREETECH control board kit.

• ການກຳຈັດຂີ້ຝຸ່ນ: Periodically clean the control boards and fans to prevent dust buildup, which can hinder heat dissipation and lead to overheating. Use compressed air or a soft brush.
• ການເຊື່ອມຕໍ່ສາຍ: Ensure all cable connections are secure and free from damage. Loose connections can cause intermittent issues or component failure.
• ການອັບເດດເຟີມແວ: Regularly check for and install firmware updates for both the BTT Pi and SKR Mini E3 V3.0 to benefit from bug fixes and new features.
• ການກະຈາຍຄວາມຮ້ອນ: Verify that the cooling fans are operating correctly and that there is adequate airflow around the control boards. The SKR Mini E3 V3.0's three CNC fan interfaces are crucial for maintaining optimal operating temperatures.

ການແກ້ໄຂບັນຫາ

This section addresses common issues you might encounter with your BIGTREETECH control board kit.

• ເຄື່ອງພິມບໍ່ເປີດ:
  • Check all power connections to the SKR Mini E3 V3.0 board.
  • Ensure the power supply is functioning correctly and providing the correct voltage (12V/24V).
• Motors Not Moving/Incorrect Movement:
  • Verify motor cable connections are secure and correctly oriented.
  • Check Klipper configuration for correct stepper motor settings and pin assignments.
  • Ensure TMC2209 drivers are properly configured (UART mode).
• Temperature Reading Errors:
  • Inspect thermistor connections for looseness or damage.
  • Confirm thermistor type is correctly set in Klipper configuration.
• Connectivity Issues (Ethernet/WiFi):
  • For Ethernet, ensure the cable is properly connected and your network is active.
  • For WiFi, verify the antenna is attached and WiFi settings on the BTT Pi are correct.
• Power-loss Recovery: The SKR Mini E3 V3.0 supports power-loss recovery. If a print is interrupted due to power failure, the board can resume printing from the last saved position once power is restored. Ensure this feature is enabled in your firmware configuration.
• ການ​ກວດ​ສອບ Filament Run-out​: The SKR Mini E3 V3.0 supports filament run-out sensors. If your printer stops mid-print, check if the filament sensor has been triggered due to filament running out or a jam.
• ປິດອັດຕະໂນມັດ: The SKR Mini E3 V3.0 can be configured for automatic shutdown after printing using a PS-ON interface. If the printer does not shut down automatically, check the PS-ON connection and firmware settings.
