Looks like the fan does not do its work.

Try to print two of them simultaneously, at distance to each other. So there is time for cooling.

No, both fan's works (Test in Menu) ..

Now I am very disappointed and angry.

The next print is completely out of the question. Flat surfaces prints the M300 without problems. But as soon as curves are printed upwards, we destroy the “back” part and ONLY the back part of the print.

The nozzle was cleaned after the last fiasco, leveled bed.

It prints ONLY in the REAR of the print object and in curves in the amount of dirty, out of round, uneven and color “burned”.

Fans seem OK, filament runs clean from the roll.

Printer seems defective !!!

Finally, here is a test file for a printer test that looks just as gruesome in places and the material has changed again in color.

But again only in the back !!!

That for a >3000 € printer.

WHAT is going on with this printer ???

In your first two examples, I think the problem, as goldenage said, is that there is not enough cooling time between layers. You have a small vertical feature, so the nozzle is spending a lot of time in a small area and the filament is too hot and cannot cool between layers. As goldenage suggested, you can print two copies of your object so that there will be more cooling time as the nozzle moves from one to the other. Or you can try "auto" fan or 100% fan speed.

For the last test, that is a crazy "torture test" object, and very hard to see what is happening from your photos
