MakerBot Mini not finding center

[charleskeezer]

this is strange. my printer was doing just fine. I have had it under a year and have printed many items without issue. in my last print the belt clip broke. this caused the extruder to go a little haywire and was printing all of the place. I had a local shop print me some new ones installed them today and now the extruder never starts in the proper starting position. It starts off the plate which causes the plate to move into the case of the extruder and whatever the larger part is behind that. makes quite a lot of grinding noise. I have tried manually moving the unit around and that is all but impossible, and i am sure not healthy.

Any tips would be amazing.

Hi Charles,

Try manually turning the threaded rod at the back of the printer while the printer is off. Turn it in the direction to lower your plate all the way to the bottom. Then restart the printer and you should not have any more crashes.

Best regards,
Peter

There may not be enough tension on the belt. The left motor bracket is adjustable. Loosen the set screws, then loosen the bracket by adjusting the screw in the back. Reattach your belt. make sure the belt ends are as close together in the clip as possible. Then reattach the clip to the carriage. Once it’s all back together, retension the belt. Don’t make it super tight, like a guitar string. It should have some give when you press on it. Good luck.
