Plotter test was much better with the wheel spacers than without them. It is still not perfect yet. I am about 3.5mm off at end of plot from where it started. The best I had before was about 12mm. I will reprint the wheel endplates with higher infill to see if that helps. it has a little flex in them at 4 perimeters & 30% gyroid infill. A friend suggested using a yoga mat for the rolling the plotter on, but it was not as accurate as rolling on the vinyl cutting board. Here is the test video running at 1800mm/min.
