I've been having similar ideas for my mill (ZX-45). I have two gear levers. High/low and I-II-III What I idealy like to have is two servos to shift the gears into right position before starting the motor. So M3 S1000 will select the best gear for this speed. As a intermediate solution I'd like to do as you suggest. Put some switches on the gear levers, and give an alarm/warning/change gear message if the requested speed is impossible with the current gear position.

This would be sufficient for me as well. Not sure how to wire this with HAL. Suggestions?
