Here is some experiments from last night. Second two last images shows what happens when the supports are to weak and loose grip with the board.. I am using the gray filament for all these tests cause I found out that both black and gray gives much more stringing and much less grip for paint later on. When I got it right I print another in white filament which gives a much better surface and just fantastic grip for paint afterwards. I googled around a lot, but no one seems to (what I found so far..) complain about the difference in filament colour. Clearly there is "some" difference ....
For coming prints I will add a little "foot" to each support so it doesn´t loose it. It is a great learning experience!
