Xy Home Calibration; Z Zero Calibration - Stratasys Fortus 450mc User Manual

XY Home Calibration

The printer is designed to automatically perform an XY Home Calibration as part of its
initialization and startup process. Each time the printer is powered on, it will automatically
perform this calibration. The XY Home Calibration is responsible for finding the home
position for the X and Y axes. The home position is a set location the system references for all
movements.
Note: You can manually perform this calibration using the XY Home button (see
"Calibration Controls" on page
The XY Home Calibration requires no user interaction. When homing XY the printer will:
• Find its Z home limit switch
• Find its X and Y travel limits
• Return to the head parked position

Z Zero Calibration

The printer automatically initiates a Z Zero Calibration before each job is built; "Finding Z
Zero" will be displayed within the Information Bar while this process is occurring. This
calibration sets the reference point between the model tip and the build sheet to ensure
proper positioning for the first layer of a build.
This calibration requires no user interaction. When performing the Z Zero Calibration, the
printer will find the Z end of travel sensor at the bottom of travel and will then find the tip
sensor using the model tip. Based on this positioning the printer knows the reference
distance between the tip sensor and the build sheet.
