Hello. We've just completed our first attempt at making our funky Z-clearing algorithm work through a web-page for anyone to try out for free.

Don't all rush at once and drive our server into the ground, but feel free to try anything out. We'll try to keep it running and fix it when it crashes, but we can only do this during the day (local time in Liverpool).
We've done our best with it, and now we're looking for some applicable suggestions, both on this web interface idea, and on the toolpaths themselves... if someone actually gets far enough to actually try cutting with them.
