May be a scaling problem. My long ago defunct plotter
had a 1/10 mm step size. Unfortunately most software
outputs in mils. So I ended up drawing IC's with 10 mm
pin spacing rather than the expected 100 mils (2.54
mm).

Solved it with a perl script that read in the file and
converted before spitting it out at the plotter.
