bravo you are connected to Klipper!
-
if you have a pi and you have kept the base user: it is in /home/MKS/printer_data/gcodes
otherwise it is in /home//printer_data/gcodes -
for backup you can also copy the printer_data directory with winscp to a USB Key

here is the final procedure (be careful not to manipulate other files at the risk of compromising the proper functioning of Klipper!
I am not responsible if you make a handling mistake; i suggest you take a backup of your EMMC…
