Factory reset (SL1/SL1S) | Prusa Knowledge Base

Stored separately from the firmware itself, you have calibration data related to the operation of the printer and various statistics. If these values become corrupted or are not compatible with a new version of the firmware, you can have some issues. If so, we recommend doing a factory reset.

Doing a factory reset will clear statistics data, like total printing time and material use.

There have been some changes to the menu structure of the SL1 between firmware versions. Therefore we will outline how to do the procedure starting with the latest version.

Procedure FW 1.5.0 and above

The Factory reset can be performed from the LCD menu -> Settings -> Firmware -> Factory reset.

Procedure FW 1.4.2 and below

The Factory reset can be performed from the LCD menu -> Settings -> Advanced Settings -> Factory reset.

Upgrading the firmware

If you are seeing any inconsistent behavior we recommend also updating the firmware. A factory reset followed by flashing the firmware and recalibrating will resolve most firmware issues you may encounter. Please see Firmware updating (SL1/SL1S) for more information.
