The Original Prusa XL is equipped with a loadcell, to detect that the nozzle is close enough to the steel sheet for printing, and to avoid damage that would be caused by the nozzle digging into the steel sheet.
During a selftest the loadcell is calibrated. The loadcell can also be calibrated at any time through the printer menu. If the loadcell calibration is not done, or the printer does not recognize that it has been done, it will show the message "Loadcell calibration is incomplete. Restart the printer and calibrate loadcell."
Error name: Loadcell not calibrated
Error code: #17523
Open the dwarf-cover-door to access the Dwarf board. The loadcell connector is on the bottom left, check it for any loose cable, disconnected cable, or visible damage.
Navigate to LCD Menu - Control - Calibration and test - Loadcell test to restart the loadcell calibration.
During the test, you will be asked to tap the nozzle at a specific time, and a progress bar on top of the screen will be filled. If the progress bar is not filled or the printer shows any errors, please contact our customer support.
