Gcode to tell a RepRap 3D printer he is in the middle of the heat bed?

Is there a way to tell a RepRap 3D printer that he is in the middle of a heatbed using a specific gcode?

Solution

  • You can set the coordinates to start at center (once you are already there) via G91:

    G91: Set to Relative Positioning

    Example: G91

    All coordinates from now on are relative to the last position
