Haven't really tried it yet, I'm missing a piece of the extruder. Although I did modify the extruder to work temporarily, there is always filament bleeding through the nozzle...eventhough none is being fed. I haven't had much time. I'm still trying to figure out why the filament is leaking, there must be pressure in the tube. I'm letting it heat now to see how much filament will bleed before it stops.

Thx
