I played around a bit with this tonight. I never noticed any funny business before because i don't have speed feedback from my spindle, i manually set the speed using a mechanical transmission and LinuxCNC just turns it on and off at that speed, totally ignoring the S-word and motion.spindle-speed-cmd-rps. In 2.6 (v2.6.7-14-gde51d6b), sim/axis/axis.ini, with the spindle off, i can use MDI to program S1000, and it shows up in the Active G-Codes. If i then program M3 i get the commanded 1000 rpm speed, as expected (as indicated by motion.spindle-speed-cmd-rps). If i use F9 to turn the spindle on, it turns the spindle on at 200 RPM (or at whatever [DISPLAY]DEFAULT_SPINDLE_SPEED says, presumably), independent of what the programmed S-word says. If i'm running a program, clicking the Stop button (or hitting the Escape key) stops motion and the spindle, which is good and right. F9 starts the spindle a [DISPLAY]DEFAULT_SPINDLE_SPEED, and M3 starts the spindle at the programmed S-word speed. 2.7 (v2.7.0-pre5-28-gb1c6283) behaves the same way, so that's good. So i think the only wonky thing here is that F9 doesn't use the programmed S-word. I think F9 should start the spindle at the programmed S-word if there is one, and default back to [DISPLAY]DEFAULT_SPINDLE_SPEED only if there is *no* programmed S-word.
