I purchased a FlashForge Creator pro a week ago and it initially worked well (for about 6 prints). It now only prints the first 3 layers or so and then becomes clogged, or the filament will wined itself around the stepper motor. I have been printing with PLA and a range of tempters (195 - 215 C) and have the same problem all the time. Is there something wrong with my settings that causes my prints to fail?
