Our Quilt Plotter’s rather frustrating software automatically resamples
DST files, for no explicable reason. While we struggle to communicate with its manufacturers to overcome this “feature,” I attempted to explain the problem in pictures.
1. A line, or vector file, is not a DST file yet. A DST file is comprised of many points, like so:
2. This has a high sample rate, because there are many points spaced close together.
3. Above is a lower sample rate, with “stitches” in black. There are fewer points and they are spaced further apart. Here’s a resample at the same sample rate (frequency/spacing of points):
4. Every time the path is resampled, it moves further from the original line. This happens even if it’s resampled at the same sample rate, as shown here.
5. Same sample rate, worse fidelity because of resampling.
6. If we resample enough times, eventually our path won’t resemble the original line.
7. Not what we want.
THIS is what we want the machine to read. We can control all the points in the DST file in Mathematica. We just want the machine to not resample them, to keep the points in the original file we give it. Here the points are evenly spaced except at corners and curves to preserve fidelity.
