Cannot get a good print on my UM3

[latreides 4]

I have a new UM3, and for the life of me, I cannot get a good print out of it.

This is a new UM3, with a fresh/new install of Ultimaker Cura 3.x, using a default UM3 profile (except I changed the 'Wall Line Count' to 6), using Ultimaker PLA filament with an AA 0.4 mm core.

I tried printing a part to this spool holder (multiple times) and I always get the same results.

The ugly marks on that are where Cura has oozed filament out onto the build plate and then the next layer squishes them into the part.

Here are some more:

And on the other side:

Some of that last image might be z-scaring, but most of the lines clearly show a piece of filament embedded into the part.

To be clear, the oozing is the only issue its having (but its a big one). Every other aspect of the print seems to be working as desired.

I cannot be the only one running into this issue. I had a UM2+ hooked up to a different computer, running a different version of Cura, slicing different models, and I was getting the same oozing results (I made a topic on this forum about it) and the only way I "solved" that was to just use S3D, which didn't suffer from this issue. S3D is not an option with the UM3, so I need to actually solve this so the UM3 doesn't end up being a paperweight.

Does anyone have any suggestions/recommendations/etc...?

Try cutting back on your temperature. I have found that going back about 5°C has done wonders for my prints.
