Model-based bed roughness

Post by Dreide »

Instead of having just a single parameter for bed roughness, have the option of specifying a text file with X,Y,Z coordinates (basically the bed height measurements for a regular X,Y grid), where Z is the bed roughness to be applied according to the XY positions of individual line segments. KISS would use a bilinear or bicubic interpolation/extrapolation to calculate the bed roughness values for each line segment. Very long line segments would have to be split according to the grid resolution so that the material flow can be adjusted often enough along the path. Since this affects the first layer only, it should have no negative effects on execution time and file size.
EDIT: Oh, I just realize that I didn't really mean Bed Roughness but more something like variable extrusion height within the 1st layer. Obviously, it is not the Z position of the print head that should vary, but the flow rate.
