Who are you asking?

I was in a thread a few weeks ago and it was pointed out to me how much Yaskawa had come down in price. You can get 750W set for around £450-500 on Ebay just search Yaskawa Sigma. I'd use these over most other makes and DMM or Delta etc don't compare to Yaskawa, esp when it comes to tuning and software. They basically tune them selfs on the fly. Go to youtube and check out the Vides and the tuning software.

A good shout. The 'premium' brands are worth it if you can afford their kit.

You did a very positive youtube video on the BST servos/drives, how did they perform on the machine? The 750w Yaskawa drives at £500 is that second hand.

If you are talking about the 1.8Kw then yes they worked fine, they actually ended up on a Lathe. Well 2 did the third I still have waiting for a project.
I've also got some 600W 60mm here that I may do a video on as well.

The Yaskawa where new here a link for one I just did a quick search on Ebay, if you look around you may find them cheaper. They are fluctuating in price I've noticed, obviously because of the state of the markets.!

Colin if you use servos what controller are you going to use and how do you plan to run them.? Analog or Step/Dir.

I have a Denford Easiturn 3 which had old electronics which did not work and i have removed them. I then thought i would reuse the steppers and drivers or steppers and the likes of the Leadshine 882 or if new servos are a direct replacement (mechanically) then the BST servos at about £250 each looks a decent bet.
On the controller front the Chinese controllers look a better bet than the mach3 bits and pieces which look like a project in themselves. A decision must be made before the controller is purchased as i believe i must specify incremental or absolute type (whatever that means?).
I was looking at the GSK clones such as Newker http://newker-cnc.com/index.php?m=co...=166&l=3&id=91

I don't know i will need to find out. Do the cheap Chinese controllers do both methods?
