Hi everyone
I'm building a plotter for printing resist onto pcbs. I want to be able to
draw the artwork in Protel and then output it to a HPGL file. (I think its
HPGL for plotter outputs) I then want to import that into a windows program
that I'll write which will drive my plotter.

Does anyone know how HPGL works, or know of any links? How can I read the
HPGL file and then drive my steppers? Is it in text format?

Does anyone know of any links to similar projects?

Thanks in advance

Justin G
