I worked in cradek's irc remarks from yesterday I also made an attempt at the yz/xz planes 'by analogy' from cycle_feed() - I am unsure wether this a) makes sense b) is correct http://git.mah.priv.at/gitweb/emc2-dev.git/shortlog/refs/heads/g84-dev I would appreciate a test/feedback by the inte

This is how I understand it. Emc only looks 1 segment ahead for blending. (I think cutter comp may look a little further for checking on gouging but that is just a feeling) g61 - exact stop mode. (self explanatory) g64 - constant velocity. It will go as fast as it can while still touching e

One of the hackerspaces I worked with in the past just modified a Taig for CNC. One of the members tested a SmoothStepper from Warp9 and really liked the increase in performance. The group was discussing modifying the setup to a SmoothStepper, and one of the posters

This gives a hardware overview.. http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Emc2HardwareDesign the smoothstepper is a buffered style device as the transmitting device is not realtime. It isn't a good fit with emc and there is a lot better more robust/flexible hardware for emc (imho). (some f
