Started a print but it's not working? Look here!
There are lots of different plastics that you can print. For the most part, unless you’re doing something special (you know who you are!), you can use PLA. It prints quickly and relatively easily. The rest of this guide will assume you’re using PLA.

Print not sticking to bed
Often this is caused by contamination on the bed. Wash it well with soap and water, dry it with a clean cloth, and avoid touching it with your hands. Isopropyl alcohol with a clean paper towel can also help, but soap and water are better. There should be a mi...
Filament stuck on spool

Bed leveling or homing fails
Check the removable bed surface to make sure it's properly positioned. It should be flat on all the edges, and flush with the sides of the plate. If the build plate is all the way at the bottom of the printer, manually move it up to around the center. Fr...
Filament broke inside feed tube
Sometimes filament can break while it's being fed from the spool into the extruder. This is particularly common with older filament, which can absorb water and become brittle. To fix the issue, you'll need to remove the feeder tube from the extruder and push ...
