Are you saying the exact same configuration worked without a perceptible delay on version 2.5 and older? Same computer and operating system version? Keep in mind that halui is NOT a hard-real-time component. Anything done by halui or other non-realtime-code has NO guarantees against delays. Usually things are fast, but just like Windows will sometimes go out to lunch for a while or your browser (even on Linux) will appear to lock up while processing the latest spam-laden webpages, anything can happen once you go outside the realtime system. Halui is a user interface just like Axis, and the fact that it connects to physical buttons does not mean that it is any better than any other keyboard or mouse driven user interface as far as reliability and guaranteed speed. The only hard realtime components are the main motion controller (hal pins like motion.xxxxxx and axis.N.xxxxx) and the lower level HAL components like PID, stepgen, hardware drivers, etc. There is a HAL pin on the motion module that implements a feed-hold in real-time: motion.feed-hold. Note that it can be overridden in g-code. See http://linuxcnc.org/docs/html/man/man9/motion.9.html That said, if the halui interface used to be "fast" and now it isn't, it probably should be looked at. I'd go ahead and file the report. -- John Kasunich jmkasun...@fastmail.fm ------------------------------------------------------------------------------ Don't Limit Your Business.
