Make sure to do the following when printing for PLA:
- Make sure your model is sliced for the Ultimaker 2+ NOT the Prusa.
- Do not use glue stick, hair spray is okay
- When applying hairspray, protect the lead screw and rods with a piece of paper
- Hair spray does not need to be applied every time. Usually you can use what is already there. Ask the studio monitor or post on #3d if you have questions
