Possibly, but I cannot tell from the information Renishaw published in that brochure. The research starts by focusing on the effects of different patterns on accuracy. It could probably be used to make something very similar. In fact, that is my hope. As a note, I have no machines that need 100m/s speed, but if we could get it down to 1/10'th to 1/1000'th that it would work for a LOT of machines out there. The Renishaw Resolute is a very interesting piece of kit. Wish I had it when I was working on the LiDAR -- I could have used that to simplify a lot of issues. ------------------------------------------------------------------------------ _______________________________________________ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers
