With this simple ironing test, easy to print, you can find the best percentage value for ironing flow to set in your slicer for perfectly smooth surfaces.

You just need to download it and start the print, then evaluate which square has the best surface and enter the corresponding value in your slicer. For Bambu Studio, the parameter to adjust is "ironing flow" in the "Quality" tab.

Ideal for both PLA and PETG.
