If you are running two filament, you will find that during tool change, the un-used nozzle is still oozing out. When is time for the un-used nozzle to come back on line, it takes a while for the nozzle to be primed before filament will come out again. The end result is both a mess on the finished part from oozing, and blanked printed area. This mod will program the Bukobot to retract the un-used filament by a large number to prevent oozing out. When is time to come back on line, it will extrude a large amount over in the wipe area, then the wiper will wipe the filament from the nozzle, and ready the nozzle for print again.Files:
