For questions regarding the "homing" (positioning to a known location) of 3D printing devices.
The process of determining the location of a 3D printer nozzle in three dimension using a reference point (home location) is referred to as "homing". Homing should occur before every print and involves bringing the X, Y and Z-Axis motors to predefined limit locations (usually these are end stops). Pre-recorded homing data offset values determine the position of the build plate origin with respect to the end stop locations.
