Guys i've seen pics of some of you using servos as your spindle (cutter not control), can anybody give me some ideas of how you are controlling them? what drivers etc. I would like to go down the same route and exchange the actual spindle for a Colet chuck. I have to admit looking at brushless, brushed, AC/DC PWM is now doing my head in. It seems you can't find difinitive ideas on what rather than how people are controlling these things. Ideally i would want to plug into EMC2 for the speed control. Fern router at 30k is too much for my ears now and not enough cash for a more expensive solution. I can lay my hand on Servos easy.

What are you using please?
