I asked myself wether it's possible to use ironing for big surfaces. So i decided to test some settings and this test arised. I added a great to see its behaviour at some corners. This test is made for 15 and 20mm/s. 25mm/s is on its way. I hope it will help u.
Please notice: This values are not useful for small surfaces like letters. Therefore use my standard ironing test:
