Linear shaft fell

Recommended Posts

1 mounth using new ultimaker 3, all is ok. Today, when it works, linear shaft jumped out of the groove (1 photo). I noticed that right part or linear shaf is fixed with black сylinder which blocks him (2 photo), but on the left part there is no cilinder (3 photo). Unfortunately my seller is in another country, i have no possibility to visit him. How can I better act in this situation. Can this item be ordered somewhere ... Thanks!

On that pulley there is no black spacer. Are the pulleys on that rod fixed? If the dubble pulley isn't fixed, you can push the pulley to the frame and screw up the screws...

Now the rod must be fixed and he isn't be able move anymore.

Have you looked inside the printer for the spacer? Since the rod got loose there's a good chance the spacer fell off and is hiding in the printer somewhere. It is _very_ unlikely it got out of the factory without the spacer, almost impossible I would say.

Turn the printer upside down and shake it a bit :)

This can happen if one or more of the set screws aren't tight enough on the rod to hold the pulley in place. Make sure you go through all the pulleys and tighten the set screw on each.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
