0.6 HF SPEED vs STRUCTURAL profiles.
Not sure if this is the right place for this, but here goes...
Trying to print a square for the end of my track saw track with my 0.6 mm HF nozzle on Core One with Printed Solid Jesse PETG. I initially printed with HF 0.32 SPEED profile and got some terrible perimeters. It looks like the machine was just going way faster than the heater/nozzle could keep up with.
Tried again with 0.32 STRUCTURAL profile and got much better results.
Should the default HF profiles have worked out of the box? Or should I expect to have to do some fine-tuning to avoid under-heated perimeters like I saw?
If I have the time, I'll set up a test with a smaller model and punch through all the 0.6 HF profiles and see if any others don't produce an expected finish.

Frankly, I don't even know why the speed profiles exist… Isn't everyone interested in getting the best possible output? And we're not talking days or even hours of difference for most prints.

So bump up the nozzle temperature. And it will catch up. Non HF filaments may need more temperature to melt properly at high flows.

This is actually the same kind of problem I'm having here
Do the missing/bad extrusions cause the printer to make a noise when it misses?
What I found is that the speed profile caused the issue to begin with, but then I started having the same issue with structural too (on stock nozzle even). Would be interested to see what your results are if you try this test model I use to repro it on my printer: https://www.printables.com/model/1285853-fast-continuous-extrusion-test

If you have a non-highflow nozzle, you might try it. With non-HF settings, of course.

Is there a downside to using the non hiflo settings with the hiflo nozzle?
RE: 0.6 HF SPEED vs STRUCTURAL profiles.
Yes. It may clog the nozzle because of low temperature. HF printer profiles comes with different filament profiles, which typically has higher printing temperature.
