/**
* SpoolJoin Consumes All Filament -- EXPERIMENTAL
*
* SpoolJoin normally triggers when FINDA sensor untriggers while printing.
* This is the default behaviour and it doesn't consume all the filament
* before triggering a filament change. This leaves some filament in the
* current slot and before switching to the next slot it is unloaded.
*
* Enabling this option will trigger the filament change when both FINDA
* and Filament Runout Sensor triggers during the print and it allows the
* filament in the current slot to be completely consumed before doing the
* filament change. But this can cause problems as a little bit of filament
* will be left between the extruder gears (thinking that the filament
* sensor is triggered through the gears) and the end of the PTFE tube and
* can cause filament load issues.
