Hi there,
I have a strange topic I need to try to understand:
In the attached picture you see a part of a simple print with different cuboids. I used Blender to model the whole thing. For some particular reasons the width of the cuboids are not exactly identical. I gave some examples in the picture "Cuboids.png" attached (please refer to widths of A, B, C, D and E).
What really puzzles me are the differences how the whole thing is printed - the toolpath preview (MANY thanks for that feature by the way) however looks really fine - please refer to "Toolpath.png".
I need to understand some strange things:
a) Why are there so big differences in printing, even when the model difference (width of cuboids) are likely to be neglected.
b) Why are there some gaps, even when the model should be filled, see profiles of B, C and D? Why is A filled completely but not B, even if the difference is just 1 µm in the model? (A vs B )
c) Why is C not filled, even if its width is smaller than A? If it would be a stepper motor problem, then I would assume that the left part of C should be printed with the same width, but it isn't.
d) What can I do to get the profiles closed, without any gaps in between (e.g. at B, right part of C and D)?
I have to say that issues like these often appear in my models and I would be happy to solve these :-)
Background info:
model height: 1.5mm
Slic3r version 1.2 (similar behaviour also seen in earlier versions)
Printer: RepRap TriColor Mendel.
Host: OctoPrint on a RaspberryPi.
Many thanks for you help,
Leo
