emc's motion controller uses the following HAL pins during the G33 spindle synchronized move and G76 threading canned cycle: motion.spindle-revs motion.spindle-index-enable These must behave like the "canonical encoder interface" pins 'position' and 'index-enable', described here: http://linuxcnc.org/docs/devel/html/hal_general_ref.html#sec:CanonEncoder
It is possible to imagine a component which reads an "index" input in the fast thread and produces a "guessed" spindle-revs value every servo period based on the expectation that the spindle velocity is constant during the threading moves. However, no such component has been contributed to emc. If you develop this component, please consider contributing it: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?ContributedComponents Jeff ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
