XY Gantry Calibration
The printer is designed to automatically perform an XY Gantry Calibration as part of its
initialization and startup process. This calibration moves the gantry to ensure it can travel
properly throughout the build envelope and determines the gantry's reference in relation to the
platen. Each time the printer is powered ON, it will automatically perform this calibration. The
XY Gantry Calibration is responsible for finding the home position for the X and Y axes. The
home position is a set location the printer references for all movements.
When performing the XY Gantry Calibration the printer will move the head at a low velocity to
the full extents of travel in the X and Y axis. The homing process uses mechanical hard stops
in conjunction with commanded motion control while actively monitoring servo motor following
error. After XY gantry homing has completed, the extent of travel in X and Y is compared
against an upper and lower limit, and an error is generated if travel is outside of those limits.
The commanded motion used to determine all four gantry hard stop locations is identical. The
controller sets upper time and distance limits for each hard stop location. These limits are used
to ensure hard stop engagement occurs within expected parameters.
