I am trying to port Marlin to my Qidi Tech 1 printer which previously ran Sailfish 7.8. Everything worked fine on the old board, including the temperature sensors.

All cables except for power, LCD, and USB (for flashing) are disconnected. I am still very early on in testing and have yet to plug anything else in.

When uploading Marlin to the board, at first startup I received the following error:

```
Err: MAXTEMP: E1

PRINTER HALTED
Please Reset

```

There may be a problem with my configuration. So I commented out all of the thermal runaway protection options since the bed and extruders aren't yet connected:

```
//#define THERMAL_PROTECTION_HOTENDS
//#define THERMAL_PROTECTION_BED
//#define THERMAL_PROTECTION_CHAMBER

```

I rebuilt, flashed, reset, and the printer is still telling me that E1 is at MAXTEMP.

Why am I still getting this thermal protection message?

I cleared the EEPROM from the LCD menu in Sailfish before flashing.

This board uses an ATmega2560 and I'm using the default fuses (E:FD, H:D8, L:FF, LOCK:CF).
