This image highlights the main control chips used in the SKR V1.4 (100MHz) and SKR V1.4 Turbo (120MHz) boards, both featuring NXP LPC1768/LPC1769 microcontrollers, emphasizing the 32-bit architecture.

The image shows the BIGTREETECH SKR V1.4 board with an external DCDC MODE V1.0 power module connected, illustrating how it provides 5V power to peripherals like TFT screens, BLtouch, and Neopixels. Note that the DCDC module is sold separately.

This image points out the dedicated I2C, SPI, and WIFI interfaces on the SKR V1.4 board, which are reserved for users to integrate custom modules and facilitate advanced DIY projects, including firmware flashing and serial port debugging with a BTT Writer.

The image details the RGB light bar support for Neopixel schemes and the thermistor interface on the SKR V1.4 board. The thermistor interface is protected by a capacitor and a varistor to enhance its resistance.

This image illustrates the expanded fan interfaces on the SKR V1.4, including a 1-way CNC fan and 3-way frequent fans. It also highlights the dual Z-axis interface, which simplifies wiring by eliminating the need for an external drive expansion module.

This visual comparison shows the differences in driver-STEP/DIY mode, TMC Driver-UART mode, and SPI mode driven by TMC between the SKR V1.3 and SKR V1.4 boards, indicating simplified jumper cap configurations on the V1.4.
Installazzjoni u Setup
Installazzjoni tal-Ħardwer
Carefully install the SKR V1.4 control board into your 3D printer's electronics enclosure. Ensure all connections are secure and correctly oriented. Refer to the wiring diagram for proper component placement.

- Fannijiet: Utilize the multiple fan interfaces for part cooling, hotend cooling, and enclosure fans.
- Endstops: Connect your endstops to the X-CLS, Y-CLS, Z-CLS, E0-CLS, E1-CLS ports.
- Heaters & Thermistors: Connect hotend and heated bed heaters to HE0, HE1, HB, and their corresponding thermistors to TH0, TH1, TB.
- USB: Connect the board to your computer using the provided USB cable for communication and firmware flashing.

This image provides a comprehensive wiring diagram for the BIGTREETECH SKR V1.4 board, labeling all major connection points including fan headers, stepper motor drivers, endstop pins, heater outputs, thermistor inputs, LCD/TFT display ports, SD card slot, USB port, and reset key.
Gwida tal-Operazzjoni
Firmware Configuration and Flashing
The SKR V1.4 board comes with highly modular open-source Marlin 2.0 firmware. To configure the board for your specific printer setup, you will need to compile the firmware. This involves modifying configuration files (e.g., Configuration.h, Configuration_adv.h) to match your printer's dimensions, components, and desired features.
Once configured, the firmware can be easily flashed to the board using an SD card. Simply place the compiled firmware file (e.g., firmware.bin) onto the root directory of a formatted SD card, insert it into the board's SD card slot, and power on the board. The board will automatically update its firmware.
Funzjonijiet Bażiċi
- Power On/Off: Ensure proper power supply connection before powering on. Use the reset button if needed.
- Material Detection: If supported by your setup, the board can detect filament run-out.
- Shutdown After Power Off: Utilize this feature for safe shutdown procedures.
Manutenzjoni
- Żomm Nadif: Regularly clean the board and its connectors to prevent dust and debris accumulation, which can lead to short circuits or poor connections. Use compressed air or a soft brush.
- Iċċekkja l-Konnessjonijiet: Periodically inspect all wiring connections to ensure they are secure and free from damage. Loose connections can cause erratic behavior or component failure.
- Aġġornamenti tal-Firmware: Stay updated with the latest firmware releases from BIGTREETECH or the Marlin community to benefit from bug fixes, performance improvements, and new features.
