It can be used to replace the pot on those Chinese speed controls so you can control speed directly from your gcode.
Please let me know if you have any questions.

This sounds to be similar to an idea ger21 has talked about some time ago now. I liked his idea and have planned to have a go myself but as yet not got around to it.
Basically it was to just use another small stepper motor and drive to turn the speed adjuster on the spindle. Would be quite easy to implement and cheap also for parts.
He’s a smart bloke that ger21
