SPIDER is a small but powerful 3D printer control board. In a limited space, it integrates 8 stepper motor drives, 5A 12V power supply, 8A 5V power supply, which provides powerful energy for fans of various voltages, various RGB light strips and Raspberry Pi. You can build a 3D printer with rich functions through SPIDER. Especially for VORON V2.4, we cooperated with the VORON team in the early stage of design, and many features have been recognized by the VORON team. If you are building VORON, this will be your best choice.

• Compact size: 155.3mm x 76.5mm
• Based on STM32F446 180Mhz，all IOs can withstand 5V voltage
• 8 TMC stepper drivers support, with Uart&SPI support
• Improved TMC jumper settings again，simpler and easier
• 28V input max，12V@5A DC-DC，5V@8A DC-DC (Especially for Raspberry Pi)，[email protected] LDO
• Two car fuses for hot bed input and main power input
• Limit switch socket 24V/5V/3.3V optional, ready for more other equipment, such as -inductive sensor, BL-Touch
• XH2.54 connectors

• 3pin temperature header, you can use thermistor or thermocouple (requires AD597 module)
• Up to 8 ways PWM fans (only use 1 extrueder and no 12V/24V RGB used )，2 ways RGB led(12V & 24V optional) ，1 way 5V-RGB led (NEO-PIXEL/WS2812)
• RepRapDiscount SmartController compatible pin header on board
• UART1-Raspberry Pi pin header (including 5V@8A power supply)
• 2X4 PinHeader Out for SD Card moudle
• Onboard micro-SD card
• Type-C and Type-B USB connector optional
• EXP1 & EXP2 have more multiplexing functions, such as USART, I2C, CAN
• SD card & USB upload support
• A 4.7kOhm 0.1% temperature sensor pull up resistor is used, PT1000 can be connected directly. For PT100, an amplifier board must be used.

为了兼容某些主板，如RAMPS1.4，FYSETC mini12864 设置了 RST(R3) 和 KILL(R4) 的可选择电阻。目前，有些主板（S6/Spider）将 KILL 换成 5V，此时，请确认FYSETC mini12864 上 R4处于空贴状态，否则按下屏幕上的按钮会致使 5V 与 GND 短路，长时间操作会导致主板损坏。
In order to be compatible with some motherboards, such as RAMPS1.4, mini12864 is equipped with RST (R3) and KILL (R4) optional resistors. At present, some motherboards (S6/Spider) change the KILL to 5V. At this time, please make sure that R4 is not on the mini12864 (please remove it if it is on the board), otherwise pressing the button on the screen will cause a short circuit between 5V and GND, and long-term operation will cause the motherboard to be damaged.

目前发现有些主板在接上 mini12864，并采用 USB 进行烧录时会导致无法烧录的情况，请去除 R1 10K 电阻。
At the moment , some Spider can't upload the firmware using USB if mini12864 is connected to the board, if you run into this issue, please remove R1 resistor.

To compile the firmware , you need to install Visual Studio Code and the platformio pulg-in.

The Marlin firmware is in the firmware/Marlin folder in this repository , you can also get the firmware from latest Marlin bugfix-2.0.x branch. You need to enable following define in configuration.h file

#define MOTHERBOARD BOARD_FYSETC_SPIDER

then change the default_envs variant in platformio.ini file

default_envs = FYSETC_S6

Note: If you download the latest firmware Marlin bugfix-2.0.x branch, you may need to change the boot address yourself ,check the PR here.

Open Vscode and open platformio main page and click the "Open Project" button , and direct to the folder where you put your firmware.

If everything goes fine , at the bottom you can see several buttons

The check mark is for compiling , click it to compile.

If you generate the hex file fail you may need to open vscode using Administrator Account .

We provide several ways to upload the firmware .Uploading firmware using SD card is our default way to update the firmware as Spider already has the bootloader in it when it leave the factory. But if you once upload the firmware to Spider flash address 0x08000000, then the bootloader in Spider will be gone, you need to upload the bootloader to Spider yourself. The bootloader is in the folder named bootloader, please follow the README in bootloader folder.

Then,copy your compiled firmware file firmware.bin(If you use klipper firmware, you need to rename klipper.bin to firmware.bin) file to the SD card , and insert it to the SD card slot which is at the right side of the board, and then power up the board. You may need to wait for about 30s to finish uploading, there is LED beside the sdcard slot blinking when it is uploading.

The other way to upload the firmware is using DFU.

You can download it from ST website.

https://www.st.com/zh/development-tools/stm32cubeprog.html

Open the STM32CubeProgrammer software.

1. First power off the board
2. Then close BT0 to 3.3V pin (You can find them in the middle area of the board) with a jumper
3. Connect USB cable to the board and your computer
4. Power up the board

Now the board is in DFU mode.

REMEMBER to remove the jumper if you finish uploading firmware or it will enter DFU mode again.

Now you can connect and flash the Spider board with stm32cubeprogrammer with the following operation.

Do as the red number shows in the screen shot.

1. Click the button to find the DFU port.
2. Connect the DFU
3. Choose the "firmware.bin" file.
4. fill in the 'Start address' with 0x8008000
5. Start Programming

You need to follow the Klipper installation guide to install Klipper.

When calling "menuconfig", enable "extra low-level configuration setup" and select the "12MHz crystal" as clock reference.

If you choose boot address setting no in Klipper, then you can follow Upload the firmware(DFU) to upload the firmware to Spider board. But you need to set the 'Start address' to 0x08000000. So the sequence be

1. Click the button to find the DFU port.
2. Connect the DFU
3. Choose the "klipper.bin" file.
4. fill in the 'Start address' with 0x8000000
5. Start Programming

We have two pre-build firmwares for you klipper.bin and klipper-UART0.bin (The differences between two firmware , you can check README here). But it will be outdated as time pass. We will try to catch up with Klipper, but i recommend to build the firmware yourself.

You can also choose 32k boot address in Klipper. Then you need to flash the spider board bootloader first. The bootloader is in the folder named bootloader in this repo, please follow the README in bootloader folder. Then you can follow Upload the firmware(SDCARD) to flash your built Klipper firmware to Spider.

As RRF firmware requires more than 512KB of Flash space, the Spider equipped with 446 cannot meet its requirements. So it needs to disable some features to make it work, please check the README in firmware/RRF path.
