3D Printer Maintenance

On the Makerbot what do you press from the home screen to change the filament?

• Filament

• Support

• Material

• Upload

Why does the extruder always heat as a first step in unloading filament?

• So the filament doesn't get stuck when removing

• To melt the rest of the filament out

• To complete the last print job

• To get ready to print

When loading the filament spool how should the filament go in from the spool?

• from the top of the spool into the machine

• Under the spool and then straight up

• twisted in a knot

Which is a sign the filament is loading correctly? Check all that apply

• The filament is moving from the spool.

• The filament is returning to the spool

• The extruder heated

• You can see the filament moving in the boden tube.

Which steps do you always need to take on the Makerbot when changing the filament? Check all that apply

• Replace the cover over the spool

• Clean the plate

• Replace the small panel over the feeder

• Turn off the machine

Why do we need to store filament in a bag or the dehumidifier box

• To keep moisture out

• To keep dust out

• To keep in moisture

• To prevent tangling

Why would we level the print bed? Select all that apply.

• To ensure print bed adhesion

• To keep the extruder from pressing too hard into the plate

• To stop the bed from being crooked

• To clean the print bed of old material
