Firmware updating and flashing

Updated 4 months ago ​by Tomáš Chvalina

Updating the printer's firmware is recommended for all users as it brings new features and bug fixes. For flashing the firmware you need a computer (Windows, macOS or Linux) and a USB cable, preferably the one, which was included with your Original Prusa i3 printer.

First, check the firmware on your printer. Power it up and using the LCD go to "Support" - "Firmware [version]"

Second, go to the website, select your printer and compare the firmware version to yours.

In case you need to upgrade the firmware, please use our step-by-step guide: Upgrading the firmware
