Phrozen Firmware: How to Replace

Users of Phrozen resin 3D printers are often faced with the question of how to reflash their printer (i.e. to replace its firmware) when it starts to malfunction.

Read the detailed instructions for flashing Phrozen 3D printers.

 

The printer is not responding when turned on

If, after turning on the 3D printer, the loading screen “freezes” for more than 5 minutes, then its firmware must have malfunctioned and therefore needs replacement. Replacing the hardware in the printer is called (re)flashing.

  

The definition of firmware

Firmware is the “brain” of the 3D printer, or rather, the program that helps the device read G-code. Depending on the modification, the firmware contains some additional information, for example, on operating the printer via interfaces. In Phrozen printers, the firmware is located on a micro SD card that can be easily removed from the back of the printer.

The name of the selected file will appear in the search bar. Click the Write button and wait while the file is written to the SD card.

After the process is complete, click OK and remove the memory card from the card reader.

  

3. Downloading to the printer

Return the card to the appropriate slot of the printer and turn on the device. The loading may take 2–3 minutes.

If the problem persists, you have to replace the micro SD card with that of the same size (in this case, 16 GB) and type (in this case, HC) and repeat the operations described above.
