For getting the correct flow for each filament, I make this test and my wall flow test: https://www.thingiverse.com/thing:5393518 with every filament on every printer that I have.

With these two tests you can easily and quickly find out, how you must adjust the flow and wall flow for the perfect print.

I advise you to start with 95% to see if you need to got higher or lower or print all of them at once like I did. (at 60mm/s it took my printer 43 Minutes, a single test was 4 minutes) That's easy to do, just click on the settings in the screenshot and choose "Flow" from the list that you will be shown and change that to the according number.

If you need the numbers below 90, leave a comment, I will add them eventually.
