1. Filament not extruding properly?
A: Check the type of filament you're working with and set the proper extruder temperature based on the filament type and heated build platform if applicable; trial and error. Rule of thumb is to set the extruder temperature to the highest temperature for the specific filament, then decrease the temperature by 5掳C until properly extruded. Please note this will vary with each 3D printer.
2. How do I store my filament?
A: Most filaments tend to absorb moisture from the air; because of this your filament can become brittle and slowly degrade the quality. It's recommended to keep unused filament and store it in a storage container or zip lock bag with a desiccant.
