I don't think Glowforge does DXF natively, but it should be easy enough to
convert to SVG using e.g. Inkscape. I have a small paper-tape-pattern
Python app that generates svg for this purpose - very much like your
ptap2dxf, but less sophisticated :)
It would be easier to cut from sheet (with a border line) than to cut 1"
tape. Then alignment wouldn't be at all critical.
Another material that works well is subway tile, although I don't have a
reader for that. Unless someone has already built a cellphone app that
reads 8-level tape...
Unfortunately I don't have access to the cutter right now, it's under
lockdown, so although I'd like to try more fun and games with it, they'll
have to wait...
