I think by axis is probably the wrong way to think about it, and you should consider rapid vs feed instead, as linuxcnc already does? http://www.linuxcnc.org/docs/html/man/man9/motion.9.html motion.spindle-at-speed IN BIT: Motion will pause until this pin is TRUE, under the following conditions: before the first feed move after each spindle start or speed change; before the start of every chain of spindle-synchronized moves; and if in CSS mode, at every rapid->feed transition. ------------------------------------------------------------------------------ Get 100% visibility into Java/.NET code with AppDynamics Lite!
