Not sure who used the Panasonic servos but in my case, I used DMM Tech servos for X and Y, as mentioned on the controller thread http://www.mycncuk.com/threads/13520...the-controller I was living in Vancouver at the time, so I drove over to the DMM Tech building and picked them up in person.

DMM Tech seem to me to be somewhere between hobby and industrial. No disrespect to them intended but they really aren't in the same league as Panasonic, Yaskawa etc but there again, they don't claim to be. And the pricing is an order of magnitude less. As I've spent many years myself developing similar products, I took one of mine apart and it wouldn't get through a proper design validation test - but it works fine in my workshop environment for my purposes so I'm happy.

There seems to be a Korean supplier on ebay who recycles servos, motors etc that have presumably been swapped out (preventative maintenance) after reaching their service lifetime on mainstream industrial machine tools. That seems like a good option for getting hold of good quality ("proper") gear at sensible prices. Can't recall the name, mind. Perhaps somebody here knows.
