What happened?

The Original Prusa MK4/MK3.9 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 not finished. Finish the calibration first."

Error name: Loadcell Not Calibrated

Error code: #13523 (MK4) #21523 (MK3.9)

How to fix it? 

A visual inspection

Before you start, make sure:

  • the filament is unloaded from the extruder
  • the printer is turned OFF and unplugged from electricity
  • the hotend and the heatbed are cooled down to ambient temperature

Access the LoveBoard, locate the loadcell connector and cable, and check for any loose cable, disconnected cable, or visible damage. The loadcell connector is indicated with the orange arrow in the picture below. 

Re-calibrate the loadcell

Do not manipulate or touch the printer unless the instructions on the printer screen prompt you to do so.

Navigate to LCD Menu - Calibration - Diagnostics - Test Loadcell 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.
