I have the FlashForge Creator Pro printer (Makerbot Replicator Dual knockoff). The time of slicing isn't the real problem for me right now (although, as I mentioned, a 2 MB STL only got to 20% prepared after 3 days, so I'd like to solve that eventually)--the real problem is that the .x3g it's outputting seems to be messed up in some way. I've detailed that in my posts on this thread. It's very peculiar, somehow the slicer is producing problem-free .x3g's on small files but buggy .x3g's on larger ones. I want to throw the thing through a window I'm so frustrated.
