Hello,

So I have gotten over all of my extrusion issues and was able to do 3 successful 3D prints in a row! (with the right extruder). Now, since I 3D printed the Filament Tube holder http://www.thingiverse.com/thing:409297 I want to remove the filament that is already in both extruders, so that I can install it and use it. Problem I having is that I cannot remove the filament from the left extruder. I tried loading for a few minutes then unloading and it seems stuck and I cannot pull it out. The filament in it is ABS and it still extrudes perfectly, but I cannot remove it when unloading or while loading.

Is this a common issue? Is it because its jammed inside? It does extrude perfectly still when loading. What can I do to fix the problem?
