A large, slow first layer tripped AFC's buffer fault detection ("AFC NOT
FEEDING"). _FIRST_LAYER_FAULT_DETECTION ON=1 at the end of PRINT_START
sets first_layer_sensitivity (4: pause after 70 mm instead of 30 mm);
ON=0 restores the [AFC_buffer] config value. The slicer calls ON=0 at
the start of layer 2:
{if layer_num == 1}_FIRST_LAYER_FAULT_DETECTION ON=0{endif}
_PRINT_CLEANUP calls it too, for prints that end in the first layer.
ON=0 only restores what ON=1 changed.
