2000 causes errors - only part of the file was cut and there were some strange movements added! tried 200 but this didnt help.
i went down the route of trying to use arcs to solve the problem and get faster smoother motion, but as we know got another problem with the A axis spinning in the material. i am amazed that tangential cutting is not designed to work with arcs since knife cutting needs to be high speed, and the only way to get high speed is with arcs unless you are only cutting straight lines. do you think it is worth me experiomenting or are you certina thta arcs and tangential mode do not work? i can cut without the problem of the knife spinnign on axis for most of the job but it seems to occur at least once apparently at random.
