Setup guide for Tronxy x5sa with klipper
You will need: Your 8GB Tronxy x5sa supplied SD card, a computer with SD card port/USB adaptor, another SD card for a raspberry pi or whatever pi variant you want to use and the pi variant itself; ideally an rpi but an orange pi or rock pi will do just fine.
Flash Mainsail to your pi using raspberry pi imager
Note: If you do not have a RPI then use kiauh as follows...
First install git on your pi variant:
sudo apt install git
Then...
git clone https://github.com/th33xitus/kiauh.git
run
./kiauh/kiauh.sh
and install klipper if it hasn't already been installed by the mainsail image, as well as mainsail.
Flash klipper to your printer (assumes F446 chip)
Turn off printer.
Insert 8GB SD card into your PC/linux box/mac and copy either the update-marlin or update-klipper directory as appropriate for the firmware you want. Then rename the directory to update instead of update-klipper or update-marlin - you ONLY WANT ONE of these directories present.
I have provided marlin and klipper flashable firmwares for this chipset. Here on in I will be only concerned with klipper.
Eject the SD card from your computer once the update directory is present and insert into your printer.
Turn on the printer.
Once flashed, it should beep twice to confirm; it's possible you haven't got the beeps turned on in which case just wait for 3-5 mins - your printer may look like it's crashed - IT HAS NOT do NOT worry.
The screen will not display anything of interest.
Next ssh/winscp or putty into your pi and rename either the printer_cura.cfg or the printer_superslicer.cfg file I have attached to this repository to printer.cfg first, then copy it to to the /home/pi/printer_data/config directory. Note prusaslicer does not support klipper natively; I think a good slicer choice is superslicer. Note that you can export a config bundle from prusaslicer and import it into superslicer if that was your previous slicer.
Insert IP address of your pi into your browser and you're almost good to go.
Slicer configuration
Prusa/Superslicer
In Printer Settings ~ Custom Gcode ~ Start gcode: enter...
PRINT_START EXTRUDER={first_layer_temperature[initial_extruder] + extruder_temperature_offset[initial_extruder]} BED=[first_layer_bed_temperature] CHAMBER=[chamber_temperature]
In end gcode enter...
PRINT_END
Make sure you set (using the cog icon in printer settings) your printer name, the ip address of your pi (without http://) and the printer firmware to klipper.
