Hobby CNC machines are usually based on Arduino/Woodpecker CNC controllers with cheap motor drivers and 775 spindle motors. Motors are specified to run on 36V but CNC machines usually run it on 24V. That means motors run on slower speed than what they can do. Some controllers are able to run 36V but 24V power supplied are delivered with them. Newer Woodpecker CNC controllers are specified to run on 24V only.
Some specifications claim that 775 motor used for spindle runs at 3000-6000 rpm when powered at 24V and gets up to 9000 when powered at 36V. I wanted to run spindle at maximum possible speed for better milling results. […]
