No air, no estop reset......

spindle.N.inhibit - (bit, in) When this bit is TRUE, the spindle speed is set to 0.
motion.homing-inhibit
motion.feed-inhibit - (bit, in) When this bit is TRUE, the feed rate is set to 0. This will be delayed during spindle synch moves till the end of the move.

Though if using master motion.feed-inhibit was (wrongly) changed to not include jogging.
