Installing Klipper on Sapphire Plus (SP-5)

Format your MicroSD to FAT32 with a 4096 allocation unit size.

cd klipper
sudo make menuconfig

• Enable extra low-level configuration options
• select Micro-controller Architecture (STMicroelectronics STM32)
• Processor Model (STM32F103)
• select Bootloader offset (28KiB bootloader)
• Communication interface (Serial (on USART3 PB11/PB10))
• (250000) Baud rate for serial port
• (!PC6, !PD13) GPIO pins to set at micro-controller startup # to turn off display at startup

Press Q to Quit and Y to save.

Note that the “make flash” command does not work with MKS Robin boards.
So run…

sudo make
sudo python3 ./scripts/update_mks_robin.py ./out/klipper.bin ./out/Robin_nano35.bin

Copy the file /home/pi/klipper/out/Robin_nano35.bin to an SD card and then restart the printer with that SD card.

Rename the firmware as Robin_nano35.bin if the TFT Display is connected, otherwise rename it Robin_nano43.bin

You can find Klipper v10/v11 Firmware ready to flash here

Klipper issues

No connection with Moonraker after updates

If you update Kliper and Moonraker with Kiauh
in the folder
printer_data/systemd
Check klipper.env

For some reason you can end up with serial connection.
This needs to be changed back to UDS.
