Sometimes it is necessary to reinstall an older version of the firmware. The normal flashing method only allows newer firmware versions to be flashed. To flash the same firmware, or an older one, follow the steps below.

  1. To find the older versions, go to the Downloads page, select your printer, and click on Older versions.

  1. Load the .bbf file directly into the root folder of the USB drive.
  2. Insert the drive into the printer.
  3. Push the reset button, and once the printer logo appears on the screen, press and hold the knob.
  4. On the new screen, confirm the update by selecting the "FLASH" button and pressing the knob. 

If it repeatedly only boots the printer and gives you the home screen try to format your USB flash-drive or try a different one. Even if the flash drive works with G-Codes and printing, it may not work for flashing the firmware.
