Adaptive feed was added to LinuxCNC specifically with the EDM application in mind. The idea is that some combination of external circuits and HAL blocks would generate a value between 0 and 1 which would control the rate at which LinuxCNC traverses the programmed path. > I don't know if the trajectory planner keeps the move history, if it > does then it might be possible to allow negative adaptive feed. Unfortunately negative feed would require major rework - there is no history of the path that has been executed. (That has also been discussed at length in the context of EDM.) -- John Kasunich jmkasun...@fastmail.fm ------------------------------------------------------------------------------ Everyone hates slow websites.
