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.
Ultimately I used a gel style superglue to fill in the gap and it worked. Even if it doesn’t bond to the metal it’s just there as a filler. I can’t find a replacement part or an stl. There’s zero play now and I’m getting good prints. I see a lot of other issues happening long before the bearings go bad.
