How to home only ONE axis in Marlin
In the Marlin 3D printer firmware, you can home one axis without homing the other axes using G28[Axis].
In order to home the X axis:
gcode_home_x.gcode
G28XIn order to home the Y axis:
gcode_home_y.gcode
G28YIn order to home the Z axis:
gcode_home_z.gcode
G28ZHoming X & Y without homing Z
You can also home multiple axes using G28[Axis 1][Axis 2]. So in order to home the X and the Y axis (but not home the Z axis), run
gcode_home_xy.gcode
G28XY
