So, for a starter project, I'm going to make a pair of boards that work together. I'll be making my own version of the NFC board emulator, but with a twist, it will work in tandem with another board which will replace the little Flash/EEPROM that's on the main board. Once installed and programmed with a valid tag serial number that the user already has, the printer should operate forever without needing any further intervention! The NFC emulator when updated by the printer will instead write the same value or subtract only 1 meter(and wrap around when it hits zero). It will then commandeer the SPI ROM and synchronize it with the same data. There will be a pushbutton switch and an LED that will be accessible on the board for cycling through seven "virtual" colors. That will allow up to seven total temperature settings in case XYZ expands on the three settings they have now. The only hardware mods that aren't drop in will be replacing the SPI rom 8-pin chip with a surface mount header connector that matches the footprint, running a 2-4 wire cable from the main board area to the bottom of the NFC emulator(where the antenna connector used to be), and drilling a small hole or holes in the NFC board cover to access the pushbutton and view the LED color. There will also be a USB console port that can talk to a serial terminal, but after entering a valid serial, password, and pack, one should not need to "jack-in" again. That initial process could be done before the board is installed in the machine if I design it right.

I realize this is a sort of "me too" project or the combination of a couple of them, but this would currently be the lowest maintenance solution once installed.
