Factory reset

Updated 3 days ago ​by Tomáš Chvalina

Factory reset is a feature with which you can reset your printer to the default settings. Either reseting all of the settings or only a specific group.You shall consider Factory reset if you are experiencing strange firmware problems. 

There are two different approaches how to factory reset your printer. Depending on the firmware version you are running. So pay extra attention which firmware version you are running. You can check your current firmware version in LCD menu - Support.

Firmware  3.0.11 and newer

During this firmware release we have made factory reseting significantly easier. Once following the procedure down bellow you will enter LCD screen in which you can choose what kind of reset you want to do. 

  1. Press and release the reset button (marked X and positioned under the control knob on the LCD panel)
  2. Press and hold the control knob until you hear a beep 
  3. Release the control knob

When done correctly, the printer LCD will show menu with 4 options to select from.

  • Language - option resets language preference and provides menu for choosing one
  • Statistics - will erase all the recorded print time and material from the memory. 
  • Shipping prep - which resets only the printer language selection. All the calibration data including the Live adjust Z remain intact. Even though the calibration data are still present and functional, the printer will prompt the user once to run the Calibrate Z function. This “light” factory reset is mainly used for resetting of assembled printers before shipping out of the factory so that users can select their language and run Calibrate Z after unpacking. 
  • All data - which resets everything including all calibration data and the whole EEPROM is cleaned. After this reset, the user is expected to go through the calibration flow again, except setting the probe height. 
    • (Bowden length) - only for Multimaterial firmware, in case you would change your bowden and the length would be different, then you cam adjust that in here


Firmware 3.0.8 to 3.0.11.

Full reset procedure is bit more complex as doing it accidentally user needs to spend 20 minutes calibrating.
