Shifting walls only where travel moves are...

Its hard to show everything with just two pictures, but the travel moves line up almost perfectly with the part of the print that buldges out a little. Any ideas? I use adjustable belt tensioners and have checked those.

Hi David,

We can only guess what's causing this with the limited info provided (we don't know anything about your printer). Perhaps something is binding. If you look inside the object, is it shifted towards the outside also?

Here's some general info that will help to diagnose this issue

There are a lot of things that could cause this. I've noted a few of them here: Shifted Layers / Offset Layers / Missed Steps

With more info we may be able to help.

If it's shifting only on travel moves, try turning down the travel speed. Otherwise, turn down acceleration.

I read over the links that were posted and I think it may be under powered motor. The last major hardware thing I did was turn it down due to overheating. It was about a week ago though, but maybe It hasent been noticeable until this particular print. Adjusting and testing now...will post results.

I was reading the settings you used.
Just a note about the layer height - the rule of thumb is for layer height < 80% of nozzle diameter. This is for proper layer adhesion.
Extrusion width is recommended to be between 1.04 and 1.7x nozzle diameter.
