I picked this printer up with a bunch of filament for $60. The build plate was really loose so I took it apart and found that the bearings are loose within the plastic part. Not really sure what to do here. I might epoxy the bearings in place. I saw that there is a y axis linear rail upgrade for $40 but that seems like a waste of money.
When fixing a 3D printer always go for the proper solution right away, because you will eventually get tired of the wonky half-assed solution you’ve spent hours or days getting to perform properly and just go for the proper solution anyway. Save yourself the frustration, time, and wasted filament in failed prints and do it right the first time.
