Hey guys,
So i purchased a FlashForge Creator Pro about 2 weeks back and everything was going good till yesterday. All the sudden nearly all my prints stop extruding at some point during the print. The layers start getting very thin and eventually stop all together while the motors move around as if its printing but its just printing nothing in air. i tried a few different models, and a few different profiles for my printer on Simplify3d (Fast, Standard, High) and cant seem to figure it out. I had a clogged nozzle which i opened and pushed clean and had a few good prints after. While i was clearing out the clogged nozzle i also cleaned the extruder gear… any ideas?

Probably printing too fast, too hot and maybe retraction is too aggressive.
