Marathon System Image - 02.06.2024

This image is based on V2.3.4 CB1 OS from BigTreeTech

https://github.com/bigtreetech/CB1/releases/tag/V2.3.4

The access to the SD card is not ideal. The STEP file of 'clip' that you can print, is attached. That can help with removing the card and inserting a new one.

To install it on your Marathon you have to:

1. take a fresh micro SD-Card. Use quality A1 rated SD-Cards only.
   

2. flash this image on it using 'Raspberry Pi Imager' or 'BalenaEtcher' or anything similar

!!!!!! KEEP THE ORIGINAL SD-CARD SAFE ! DO NOT OVERWRITE IT WITH THE NEW IMAGE !!!!!

3. take the electronics cover from below the printer out

4. remove the original Micro-SD card and insert the new one.
   

5. put the cover back

6. in 'MCU_serial.cfg' type the serial id corresponding to your machine
   

7. UPDATE Everything !
   

8. ENJOY and Happy Printing!
