Firmware - Klipper

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. For flashing, write the compiled klipper.bin to memory location 0x08000000 (This is because i don't find boot address setting in Klipper , but if Klipper future update support this feature, then you can set the boot address and write the klipper.bin file to 0x08010000).

If you set the address to 0x08000000 then you can't use the Spider bootloader and you can't upload klpper.bin with sdcard. Then you can only use DFU mode to update the firmware. Please follow Upload the firmware(DFU). But you need to set the 'Start address' to 0x08000000 and Choose klipper.bin file but not firmware.bin.

Also we have a pre-build firmware klipper.bin in firmware/Klipper folder in this repository. You can just use it.

And there is printer.cfg for VORON 2.4 machine , you can take it as an example.

If you can set the boot address to 0x08010000, then you can follow Upload the firmware(SDCARD).

Firmware - Marlin

Download Vscode + platformio

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

Download firmware

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_SPIDER

Compile the firmware

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

1561099422559

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

1561099546202

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 .

Upload the firmware(SDCARD)

We provide several ways to upload the firmware .Uploading with SD card is our default way to update the firmware as the board already has the sdcard bootloader in it when it leave the factory. There is sdcard slot at the right side of the board.

Then,copy your compiled firmware file firmware.bin or klipper.binfile to the SD card , and insert it to the SD card slot, 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.

Note: The bootloader is in the folder named bootloader, please follow the README in bootloader folder.

Upload the firmware(DFU)

The other way to upload the firmware is using DFU.

1.Download stm32cubeprogrammer

You can download it from ST website.

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

Open the STM32CubeProgrammer software.

1574332767079

2.Enter DFU mode

First power off the board , then jumper the BT0 to 3.3V (You can find them in the middle area of the board) , then connect the USB to the board and your computer , it will enter DFU mode . Now you can take the jumper away.

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

3.Upload the firmware

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

1574386395071

Do as the red number shows in the screen shot.

  1. Click the button to flesh the DFU port.
  2. Connect the DFU
  3. Choose the "firmware.bin" file.
  4. fill in the 'Start address' with 0x8010000
  5. Start Programming

  • Can't connect to Spider with Raspberry Pi

    Can't connect to Spider with Raspberry Pi

    I can't seem to get my Raspberry Pi 3 Model B+ to connect to the Spider v1.1 board. Here's a list of things I've tried so far:

    1. ls -l /dev/serial/by-id/ returns ls: cannot access '/dev/serial/by-id/': No such file or directory
    2. I copied ~/klipper/out/klipper.bin to firmware.bin on the Raspberry Pi's SD Card, inserted that SD card in to the spider and powered the spider on. The Flash LED blinked quickly for 10s of seconds and then became solid. I've since tried that a couple times.
    3. Before inserting the SD card the first time, I think the Flash LED blinked quickly on power up. After flashing and removing the SD card, the LED seems to stay off.
    4. When in DFU mode (jumper between 3.3V and BT0), dfu-util --list returns
      dfu-util 0.9

    It seems like the board is responding correctly to USB connections. I've tried a couple different cables that work with my phone (I can get my phone to show up in dmesg). All the appropriate power LED are on and it's able to power the Pi when it's hooked up that way. Do you guys have any other ideas of things to try? Is something wrong with my board?

    Thanks for your help! Hope I can figure this out :)

    I was going to test a spider board that just arrived but I did not get very far. There seems to be a short in the 3.3 voltage system somewhere, since the 3v3 regulator is overheating, and the voltage on the 3v3 line have droppet to 0.05v I can't locate where it is. I have added a image of the board setup and a thermal image of the 3v3 regulator.

    I can find any other places on the board that seems to overheat unexpectedly.

  • Fan0 issues with spider board V1.0

    Fan0 issues with spider board V1.0

    My Fan0 mosfet has blown up. The fan works fine, there are no shorts to it. The board still works, but there was a small fire. Interesting that "sleepingAwake" has noise in the Fan0 area. I am starting to think that this is a flaw in the board. I am however running 24v. Moving the hot end fan to the RGB pins.

    So I too am having fan issues with my spider board purchased through the AliExpress fysetc store. First the boot loader it came with somehow didn’t allow usb or uart communication. Flashing the boot loader they have here got usb and uart working. Anyway the fans. Fan0 is connected to my hot end fan and jumpered to 12v. My print config is copied from here as well with some minor changes but the pins are correct from what I can tell. At first Fan1 wasn’t working. It’s my parts fan. 24v Changing printer.cfg to below worked. I’ll tweak as needed. [fan1] Pb1

    But Fan0 nothing. I’ve tried various config changes and no voltage output.

    Also I’ve noticed when I apply some pressure around the fan0 connector I can hear a faint electric pop. It does it with the fans unplugged to. Could my board have an internal short?

    Fan0 may not be coming on due to normal behavior. Shame on me for not noticing the extruder fan behavior below 50c But my board makes an electrical popping noise if I apply a small amount of pressure around the FAN0 connector and its mosfet. Sounds like the layers are shorting to each other. Its consistent and repeatable. Nothing is loose.

    New board won’t connect

    I have a brand new board that has been in the antistatic bag until last night. I recently purchased the Voron 2.4 kit. I am unable to get it into dfu mode. I followed the instructions on the wiki. I am unable to get it into DFU mode. Since the 32K boot loader supposed to be on the board since June I tried flashing the 32K uart via SD card., which appears to have failed. And then tried doing the same for USB, and neither can connect to the pi. right now when I put the firmware on an SD and put it onto the board it stays flashing for over 40 minutes. after looking through these issue requests I tried clearing the power on the board and removing the stepper drivers and everything except for the two jumpers to enter DFU mode. It is still unable to connect and does not seem to respond via any commands. Please assist.

  • Wrong labeling of VCC and GND

    Wrong labeling of VCC and GND

    Hi!

    I am a newbie who is dealing with the Spider Board for the first time and is also building my first Voron! But when I was about to wire up the RPi, I noticed something! I wanted to connect 2x VCC and 2x GND from the Pi PWR & UART interface and it occurred to me that the pin on the top right is black, but was marked as 5V! In the other section or the picture, however, this is again listed as GND!

    Sorry i hope everybody here can understand / follow me what i mean, because my English Skills are so terrible Bed. I am a Austrian User, and could only speak German =)

    New board, unable flash firmware via SD, USB via SSH, USB via DFU both to PC & Pi

    I got a new board, tried to flash multiple different approach without avail.

    1. loading SD card with firmware.bin does not result in any blinking lights after turn on device. The SD card file remained unchanged.
    2. Plugging USB type C board with 5v jumper with U5V (I get 3.3V & 5V lights) connecting it to Pi or PC does not get pick up by either device with or without 3.3V jump with BT0. I've also tried with 24V, 5v-DC5V jumper, BT0-3.3V jumper (I get 3.3V, 5V, 24V lights) without success. And finally I have swab type C cables with all other ones (all of them can transfer data between my PC and phone so I don't believe this is the issue). I also did the firmware without any stepper, jumper (minus 5V to U5V or DC5V, and 3.3V-BT0) Do I have a DOA board? I don't believe my pi is the problem as SKR E2 mini V2 does get pickup with the same USB socket, and the PC socket picks up any other USB devices.
