I've had an Ender 5 Plus for a few weeks now. It's printing great and I've got my tuning pretty good at the moment. I've noticed some horizontal inconsistencies matching feature/geometry changes. It seems to be associated with maybe layer time(?) I only have a picture from two models, but the problem will appear in other places on different models, always matching some change in the layers.
The problem is consistent all around the model and changes position with different prints, so I know it's not a mechanical problem. Say I printed a 2x2 cm tower 20 cm tall, it will not have any of these imperfections because every layer is identical.
I highly suspect the layer time/temperature change, but I don't know how to fix this, I'm a bit stumped. They both were printed at 200 °C and I'm trying a new one at 210 °C (best temperature with the spool I have) and it has the same problem. All three models are from the same spool of PLA.
Also, I use Cura with mostly default settings for the Ender 5+.
Here are the pictures :
On the benchy it's harder to see, but the hull line match with the solid floor of the model, and the top ones match with the top window sill starting.
