X1C Specific G-Code
Bambu Labs has partially implemented Marlin G-Code commands and have added their own custom G-Code commands to perform functions that are not implemented in Marlin. It is also important to note that the X1C runs their own G-Code engine and does not use the open-source Marlin Firmware on their MC Board.
