Yes, if you're using Chiplotle to send the data to the plotter this is almost certainly not the case. Chiplotle manages the feed to the plotter so that the plotter's buffer never gets filled.

Not sure what you mean here.

Probably better to find the root problem. Could be your hardware... do you have another plotter? I would try plotting in another machine to see how it behaves.
Could also be the hpgl file itself, that is somehow not getting converted correctly from illustrator to HPGL. More unlikely, but possible.
Have you tried visualizing it with io.view()? Is the shape well formed?

Douglas has the same plotter and his would sometimes do weird things too, like stop suddenly and the like. I believe he opened it up, cleaned it, and got it to behave well.
