IF THIS PROCESS IS DONE INCORRECTLY IT WILL BRICK YOUR PRINTER! BEFORE YOU ATTEMPT THIS THE OUTCOME IS TOTALLY ON YOU!

To update anything on the Sovol Klipper screen you absolutely MUST freeze or lock the kernel to stop it being updated when you run any updates or installers. Also note this is NOT for beginners, it requires some knowledge of the system you're working on to achieve success! Please be careful!
First you have to log into your Sovol Klipper Screen using SSH. Use Terminal on a Mac or Putty on a PC.
once logged in paste in:
sudo armbian-config
It will bring up this blue background menu:
- Press enter to confirm choices & the keyboard arrow keys to navigate.
- Choose the first option
System and Security - Press enter
Now it will load a red background menu BE CAREFUL HERE YOU CAN BREAK THINGS!!! Thats why its red!
- Press enter on the top line to change it so the screen reads like the image above.
- YOUR KERNEL IS NOW FROZEN!
- DON'T PRESS ON ANYTHING ELSE
- Move down to
OKto confirm the choice & go back the blue menu. - Move over to
EXITon the blue menu. - Press Enter to exit
I find its good to do it this way as you can see its done, just don't be tempted to click other stuff!
Once you have frozen the Kernel the first time you can start from the next section below any time you need to do updates in the future. Just make sure you've done it this first time or the process WILL fail! it's very important!
Now you "should" be able to run the following commands WITHOUT Bricking your printer! Keep 'em crossed!
This will update all your system components to the latest available versions for this image.
Now that the "Buster" branch has been removed from all online mirrors these update commands below will fail due to this old & outdated system being discontiued, you will not be able to run these commands. You will get a 404 error. So skip this section & move on.
I HOPE YOU MADE A BACKUP OR CLONE!!!!
sudo apt-get update
sudo apt-get upgrade
After it completes enter
sudo reboot
Here you need your rabbits foot & to keep your fingers crossed as the new updated system attempts to start!
If it fails to start you'll need to look at unbricking & reinstalling your image. If it works like mine did GREAT well done, the tricky bit is over!
Open your web browser & head over to your printer. Then on Mainsail open the Machine tab & find your moonraker.conf file & paste in at the bottom
moonraker.conf
[update_manager]
channel: dev
refresh_interval: 168
[update_manager mainsail]
type: web
channel: stable
repo: mainsail-crew/mainsail
path: ~/mainsail
[update_manager mainsail-config]
type: git_repo
primary_branch: master
path: ~/mainsail-config
origin: https://github.com/mainsail-crew/mainsail-config.git
managed_services: klipper
Now SAVE & RESTART klipper & go back to the Machine tab, you should new have access to the UPDATE MANAGER
- Click the circle arrow button in the top of that section the get the latest update info.
- Click update on your components
- NOTE THIS CAN TAKE A LONG TIME - 10-20 minutes in some cases! Wait for it to complete
A quick note on Crowsnest before we go further, the latest version is NOT compatible with this old Buster image used on this printer. DO NOT UPDATE IT! IT WILL NOT WORK HERE!
It is very importatnt to leave Crowsnest exactly as it is!!
Your version of klipper will only be partially updated & you'll probably get a big red warning saying PROTOCOL ERROR!
& saying you need to update your MCU's!
Don't worry we're doing that now!
Now your system is updated we need to clear those MCU errors, you need to update the rest of the printer. First up get back in to SSH & enter the below commands to update the MCU RPI to the same firmware version as the new Klipper.
cd ~/klipper/
make menuconfig
In the menu, set "Microcontroller Architecture" to "Linux process," then save and exit.
sudo service klipper stop
make flash
sudo service klipper start
To be safe
sudo reboot
This will probably remove the big red error you had before but we still need to update the printer's mainboard. LAST STEP! Back into SSH again
cd ~/klipper/
make menuconfig
but this time change the options to these...
STM32F103 with a "28KiB bootloader" and serial (on USART1 PA10/PA9) communication.
Save & exit
now simply type
make
This will now build your new MCU firmware
Now use a FTP CLIENT to securely log onto the printer (using SFTP) & pull the Klipper.bin file from the klipper/out folder & download it to your computer.
RENAME THE FILE to something random, think cat walking across your keyboard random. This MUST be something different on each & every flash attempt. The board will not flash the same file name twice.
SV07 & SV07+
- Copy the file to a FULL SIZE SD CARD!!! Or at least a micro SD in a full size adapter!
- SHUTDOWN the printer & remove the mains power plug
- REMOVE THE POWER & USB cables from the screen
- Remove the draw of the printer & the full front plastic panel using the 4 large bolts on the front.
- This will expose the sd card slot on the mainboard
- Insert the full size sd card upside down into the reader until it clicks in
- Power on the printer with the screen still disconnected, making sure its safe with the front off
- Wait 20-30 seconds, longer if you wish
- Power off the printer & remove the SD card
- Reconnect both the screen's cables
- Power the printer back on
- Go to the
Machinetab & check your MCU firmware is now the same number as the other two - Shutdown the printer & reassemble to finish!
- WELL DONE!!
SV06/SV06+
- Copy the firmware onto a Micro SD card
- SHUTDOWN the printer
- Insert the sd card into the reader until it clicks in
- Power on the printer
- Wait 20-30 seconds, longer if you wish
- Power off the printer & remove the SD card
- Power the printer back on
- Go to the
Machinetab & check your MCU firmware is now the same number as the other two - You're all done. WELL DONE!!
Your Machine tab should now look like this!
I hope this helps you update your printer/s! Happy printing!
