This method requires ensuring that the printer is connected to WiFi before proceeding.
Open the Anycubic APP and select "Workbench" -- "Photon M3 Premium Printer" -- "More" (top right corner) -- "Firmware update." The printer will automatically download and install the firmware. During installation, the printer will restart, and the APP will display the printer as temporarily offline. Once the firmware upgrade is complete, the printer will return to an "Available" status.
Note: How to verify a successful firmware update?
If, when selecting "Firmware Update" again, the APP indicates "It is already the latest version," it means the firmware update was successful.
