Well!, that might be easier than I thought... there looks to be a PWM at 10kHz between the front panel control and the spindle motor driver on the main power board. I'll get probing when I can be arsed and it looks like an interface could be easy to interface with a standard 0-10V supply (microcontroller, ADC and PWM driver). Details to follow.
