Flow Test Squares

EDIT - July 12, 2024:
I've now added files for values lower than 100%, starting at 25%.

These test tiles can be used to determine the best initial layer flow setting for your printer. Ideally, you want a solid first layer that is perfectly uniform. You don't want to see gaps between the lines (under-extrusion, like my 100%), but you also don't want ridges or waves in the top surface, or inconsistencies in thickness (over-extrusion, like my 180%). Because of their thin nature, the squares can be held up to a light to help see any abnormalities/artifacts after printing. Usually, if any setting other than 100% is best, that means you should adjust your z-offset, but if you've already tried that (or are just lazy like me), changing your initial layer flow multiplier can be a good workaround.

Each square is labelled in increasing 5% values, starting at 100 and going up to 200 (I may add values lower than 100 in the future). Just change your initial layer flow setting to match the num
