Creality Print Issues with Hueforge Seashell Test

When I import the seashell, i have had to make my CFS’ black filament the #1 filament or else it imports the model to whatever it automapped there. I have white in the 1A slot of #1 CFS so it would bring in the model as white. But no matter how i would try to paint fill the model with black, i would have white still show up after slicing. So to fix that, I had to map my black to the #1 filament spot in creality print.

I am sure I am just missing a better method to paint an entire model a certain color?

So even after mapping my black filament and then setting the color filament that i am trying to determine the TD for, I am getting 13 filament changes after slicing? Why would i get 13 filament changes when my entire model was black and then i set the test filament to paint everything else above the 0.56mm level. Shouldn’t that just be 1 or 2 filament changes depending if you count the first filament as a change?

It should do black filament to 0.56mm, then change to the other color filament for the rest of the model. How could that possibly be 13 changes?

I am asking these questions, because after determining the TD for filaments with the TD1s my resulting prints are far from blending properly and i am starting to wonder if the creality print software is changing colors at the correct heights.

Ok, well digging more into this - the likely reason why there are 13 filament changes is due to the triangulation of the model itself. Since the mesh triangles are not necessarily uniform, their faces could be higher or lower than the selected paint height. This appears to cause the inclusion of different colors at higher or lower model heights than what was picked. It shows the jagged triangle painted faces when you select the height.

So because of that and the 100+ printing start/stops shown above as white dots, the seashell is near an hour to print. To avoid that wasted effort each time I print a new color, i modeled in a 15mm x 30mm step test with three rows of 5mmx5mm squares increasing in 0.08mm height from each square.

To make sure the triangles were painted at the height I wanted, I modeled the part with two sub parts. The base that is black, and the steps that sit ontop that can be changed to the filament of your choice. Since the triangles are not crossing the part boundaries, the paint line is at a defined height.

This model takes only 4 minutes of print time and I only have one filament change now.
