Right now there’s no documentation from Bambu around what standard and non-standard G-code commands can be used on the X1 series of printers.
This will be a constantly evolving thread to document these. Some things are certain, some things may be guesses/assumptions, so use the commands below at your own risk.
If you know any codes, or have any assumptions, please discuss these below and I’ll add them to this first message.
