Strange noise in XY motion

Recommended Posts

Hi all!

After a strange noise during printing the Forbidden Watchtower by Kjai I paused, resume and paused again and quit this print. Looks like it also cause a layer shift:

What's going on here? By the way I'm using UM2(+) printer, Simplify3D v4 and thinkerMarlin 17.10.1 as firmware

 

1: Bearing problem?

2: Lack of lubrication on XY the axles? It's tought to move with printer shutted down.

3: Slicer problem? In preview looks fine. Firmware problem? 

4: Belt? Everything seems in place.

5: None of the above ?

Make sure to power-cycle the printer. There was an inexplicable case where the print head made a sideways move during a print. Maybe this is related.

 

You mentioned that it is tough to move the head by hand. Maybe the belts are too tight. You should definitely not move the entire printer around if you move the print head.

      Q: For some users, abrasive materials may be a new subject matter. Can you explain what it is that makes a material abrasive when you are not sure which print core to use?
      A: Materials which are hard in a solid piece (like metals, ceramics and carbon fibers) will generally also wear down the nozzle. In general one should assume...

    • "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.
