Where is the SD card

Depending on your printer model there is a SD card inside or on the back of your Phrozen 3D Printer. This SD card is the system disk for your printer containing the operating system.

For models with an internal SD card you would need to remove the case. You can find the SD in the Raspberry PI mounted inside the machine. Its best to use a pair of needle pliers to remove the SD card.
