I’m looking to build an enclosure for my machine, but I’ve heard mixed results in regards to where to put the filament spoolObviously inside the enclosure seems more practical, but some folks say repeatedly heating the filament inside the enclosure is bad.Does this only apply to PLA and other materials with low GT temps? Is it safe to do this with ABS filament, for example? I’d prefer not to mount the spools outside. http://ift.tt/28SJjnJ
