Druid firmware is a dedicated 3D printer firmware that currently runs only on Flashforge CoreBoard (all Revisions).
Printer that uses this controller:

"T" Codes
T0-T1 - Select an extruder(tool) by index: "T<n> F<units/min>"
Note 1. Because of the small size for parameter storage (512 bytes), a 128K flash memory sector is used as permanent storage. The sector can be partially written 256 times (512 bytes per backup) before requiring a complete sector wipe, to restart the same process again. (That was 1 write cycle). The flash memory minimum write cycles guaranteed for the STM32F407 MCU by ST Microelectronics are 10000, yielding a total of 2.56 million times, parameters can be saved.
