Sporadic layer shifting

Recommended Posts

Hi

I can see from time to time a single or sometimes a second layer shift on my objects. The rest of the print is quite fine without any problems and look pretty good. The layer shift is not only in Y axis, it is also "feelable" in the X axis, but not so present than in Y.

 

Here is picture what I mean:

There is a second shift in the upper, but it is only noticeable on the picture now, I haven't seen it before.

I checked the belts and they are fine in my opinion. I think if there is something mechanical wrong, than I would have this issue more often.

 

Can it be a problem of the slicer (Cura)? I can check it in layer view, but haven't done it yet, but I am not sure if I would see such a small shift.

 

What else could cause this shift, any ideas?

 

Thanks a lot!

Thanks, I will check it in the evening, I only checked the belts so far.

 

But I have checked the layer view in Cura now and found something interesting. Not sure if it is really a failure in slicing or only an artifact when looking on the model, but there are also these shifts:

But they are only noticeable when looking from a specific angle in Cura and also only when zoomed in high enough. So probable just a display issue in Cura and not in the GCode, but how knows.

This was a iPad stand from Thingiverse, I will do some tests this evening with a simple object from Fusion 360, then I will see whats going on.

 

From time to time, I have this misalignments on single layers, but haven't checked it deeply. Most of the misalignments are always in the layer where also some other things happens, i.e. begin of a round corner, the end of another wall, ..... So maybe this is really a slicing issue and not a hardware issue.

    • "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.
