What is causing this and how to deal with it.
Take a look at this pics and tell me what you make of this "bump" in my prints.
The issue is using my Core One, Prusament PLA, bone stock .20 mm SPEED profile, 15% infill, with HF0.4 nozzle.
All the pictures I'm going to show you, were accompanied by what I can only describe as a bang/thud. Never, ever heard anything like this sound from my printer before. The one shot with with the sharp corner and steep z-axis change, the noise was very loud. Like OMG my printer is broken loud. The others were pretty subtle, but noticeable.
Hopefully you can see them with this iCloud link.
Is the the slicer allowing the head to come in contact with the print? Is that what I'm hearing?
If the pics are in order, the first 2 you can see the hump between the two holes, the next 4 are the same export just flipped 180° in PrusaSlicer. Those have the hump all the way to the top. So just flipping the job give different repeatable outcomes. The last is the pic with the god awful sound.
How do I stop it?
RE: What is causing this and how to deal with it.
Just ran another test, with Avoid crossing perimeters: Checked and Supports Everywhere.
No change. Orange does make it a lot more noticeable.
I'll keep trying.
RE:
Is the heatblock and nozzle inserted correctly and the thumbscrews are tight? That is, the heat block is not extending below the fan shroud and it's not loose? I had this happen when the screws worked loose and the heat block and nozzle were "floating/colliding" into the print.
I can't see the photos. They appear as broken links.

Okay let me see how I can get you guys some pics. To answer your question, I would assume so? Everything else is flawless only these two 3mf files that exhibit this issue.
I've got a test running using these parameters.
0.20 Structural
Supports: None
Infill: 10%
Fill pattern: Gyroid
It's only 37% done, dog slow but I don't see this hump any more.

No images showing up ... post them to the website, it is simple and easy to do and the image will never go away like most external links end up doing.
