| I bought this one on ebay (nobody bid on it, works perfect): http://cgi.ebay.com/API-Getty-servo-...QQcmdZViewItem But you can use a wide range of brushless servos. This one runs quite smooth on a trapezoidal amp. You can get those on ebay also...I have gotten them as cheap as $25 each. You can then set the amp up in velocity or torque mode and use a simple trimpot to adjust speed. Personally, I am going to reprogram one of my Pixie boards to generate precision speeds as directed from Mach3, but that is overkill for most people. I also might try and use the spindle in some sort of rigid tapping arrangement since it will have such nice control.  |
