Supplier defect?

Did you install encoders? I noticed when our students assembled them that the encoder screws pushed some plastic into the bearing cavity. It resulted in the bearing not sitting flat. That caused a little binding.

Check to make sure your bearings are pressed all the way in and there is no debris underneath them.
