I wish it were that simple! On a lot of materials, going too slow will cause problems as well. You want your "chip load" to be within a band; too slow, and you'll start burning the wood instead of cutting it. http://www.pdsspindles.com/engineering-speeds http://www.pdsspindles.com/engineering-speeds I, too, do not want to come across negative about this. I'm very excited about it. If it isn't sufficiently strong to handle some types of wood, even just being able to drop a V-cutter into the router and having it very accurately draw out all the cut/guide lines is a win for the target price. If my work flow is "draw accurate cut lines, do a rough automated cut (leaving some extra around the edges), and finish on the scroll saw and belt sander", that's great!

Yes, obviously if you're moving so slow you're not longer cutting then that won't work but that's so slow that I highly doubt it couldn't be improved on.

  Setting the rpm of the router is an ordinary setup/configuration step for doing 2d machining. I used to run 2d router systems at sign shops for years. You're always looking to optimise the speed of travel and router rpm to get the best cut qualities - fast travel with high quality cut - too fast can result in chips/burrs, too slow results in burning/melting and damage to bits, etc. I always had a list of settings to use for various combinations of materials, thicknesses, router bit sizes/types. It was a bit of a black art actually - sometimes the results of changes were counter-intuitive because of specific material properties (heat retention, etc), and that cheat-sheet wound up containing the accumulated knowledge of years of trial and error experimentation. "The only difference between Science and screwing around is writing it down" :)

    Such a cheat sheet sounds like the perfect thing for an Open Source project with a (hopefully) active community to curate.
