As I said before this firmware is specific for “flame detector” install.
Take a look and pay attention at the all process at this topic I created at the time:
You might have to plug a wire between “GND” (0V) and “S” pin to disable the alarm.
You will probably notice that through the “control” icon the direction of the X axis is inverted but through the “engrave” icon everything works properly.
For me this is a lesser evil considering that this is the only firmware to support the “flame detector” option and therefore I have no choice.
