I'm making all kinds of headway here. I just figured out how to display .3mf file extensions on my computer. 😀

Unfortunately, I don't have the project saved for the one I did in PETG.

OK, I got it. Now that I look at it I see that the first one was the wrong one. For some reason Windows File Explorer does not show the file type as 3mf, only PrusaSlicer.

Cube base 01

No, that's the bgcode file. That's even less use than a standard gcode file as its more difficult to work with as its all binary.

We need the PROEJCT file. Thats File>Save project As from prusa slicer. Get to the point of where you slice as normal and then Save it. That will save a PS 3mf format file.

The 3mf saved from PS will contain the model but more importantly ALL the settings you are slicing with. That means we can slice it identically as you and then check out the various preview options once sliced.

I think I have it figured out how to attach a file.

Looks more like a cooling issue, or rather lack of cooling in those areas to me. If you reorient / rotate the part in Z does the problem area move ? That would indicate airflow from the cooling fan not getting to an area fully.
It could also be excessive solid infill from the sloping walls being added which is a issue that has been around years and still not fixed. We would need to see your Prusa slicer project file to diagnose for sure. the extra plastic from the solid infill results in more heat in the area and hence the inadequate cooling.

Sorry for the late response, I can't seem to figure out how to post the file. I'm new to the forum so I may need to make more posts or I maybe I'm just missing something.

Thanks for the response.

The speed thing is something I just don't have a handle on yet. There seems to be a lot of choices.

I made another print this afternoon, this time with PLA and I painted some organic supports, for the most part it looks good, but.... At the very bottom even with supports it looks odd. Here are a couple photos.

I would say it looks like an extruding problem. I would try a higher hot end temp or slow the print down and see what happens. Given where it is located it might be a support issue. A couple of painted on organic supports might help?

I printed this with an MK4 and MMU3, Prusa PETG., no supports, .2mm layer height. What would cause this distortion?
