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.

Set skew correction

M1005 X##.#Y##.# ; input values from printed calibration stl
M500 ; save the values

Add the above Gcode to the last line of the “Machine start Gcode” and only run it once as the compensation will compound each time it is run. 

 

Set skew correction in radians
