Sovol-SV06-firmware

This repository contains firmware for the SV06 3D printer from Sovol. You should not use this firmware on any other printer.

Use at your own risk. I am creating these files for my personal use and cannot be held responsible for what it might do to your printer.

Installation Steps

Requirement: klipper must be installed on the RPI. Easiest is to use a Fluiddpi or MailsailOS image.

Step 1

Build Firmware Image

SSH into the Raspberry Pi and run:

sudo apt install make
cd ~/klipper
make menuconfig

In the menu structure there are a number of items to be selected.

• Ensure that the processor model is set to ‘STM32F103’
• Ensure that the Bootloader offset is set to ‘28KiB’
• Ensure 'Disable SWD at startup' is set
• Set communication to serial (on USART1 PA10/PA9)

Once the configuration is selected, select “Exit” and “Yes” if asked to save the configuration.

Run the following:

make clean
make

Step 2

Flash Firmware

The make command, when completed, creates a firmware file klipper.bin which is stored in the folder /home/pi/klipper/out.

Method 1 (Perhaps more straightforward)

1. Copy klipper.bin to a MicroSD card and rename to anyNewFilename.bin.
2. Make sure printer is off.
3. Insert MicroSD into printer.
4. Turn on printer and wait a couple of minutes (usually takes under a minute).
5. Turn off printer and remove MicroSD.

Caveat: flashing will only work if current firmware filename (anyNewFilename.bin in this example) is different from previous flashing procedure. The .bin is also important.

Method 2 (Maybe a bit advanced)

Find port that the printer board is connected to your RPI via ls /dev/serial/by-id/*. It should report something similar to the following /dev/serial/by-id/usb-1a86_USB2.0-Serial-if00-port0. Run the following commands:

sudo service klipper stop
make flash FLASH_DEVICE=/dev/serial/by-id/usb-1a86_USB2.0-Serial-if00-port0
sudo service klipper start
