What is the setting for telling the extruder to retract before it starts a long (non-printing) travel? My 1.2.9 is printing well and does do retractions, but they seem to be only on short, tight segments. On longer non-printing travels (like 6 inches) you can see the filament oozing 5mm out of the nozzle before it starts printing again, because there was no retraction before these long moves.
