Trying to plot an SVG I've generated; it displays fine in Inkscape. I have to set the document size to US Letter and re-scale the lines, but when I try to plot it the pen always just goes to one corner and moves up and down repeatedly until I plug it.
I can plot text that's been converted to paths just fine, however.

For the future, I would recommend that you update your SVG generating script to use that template (or even your new SVG created by the method above), and fill in the center part with the actual data that you want to use.
Also, the behavior that you are seeing is essentially what one might expect from a large scaling error-- it's trying to travel far outside the mechanical limits of the machine, and the "software limit switches" are limiting its range of movement, and hence leaving it in a corner. With your permission, I'll keep your file around as a test case, and hopefully we can handle scaling errors more gracefully in the future.
