Good luck on the retrofit. Let the group know how it goes.

Unless they have made changes in recent years I'd avoid then.
I had a knee mill with a Centroid controller and it was a pain. It was a wh
ile back,10 yrs maybe and the controller was running DOS 5.? I have no prob
lems with dos,it fact I miss some of the simplicity,anyway when it ran it w
as fine,but it crashed alot,and Centroid had most of the functions locked,c
utter comp was an extra $450, multiple offsets was extra, G54 was free,the
rest $750,but 4th axis was included.
And tech support,forget it.
Addendum,I had an Anilam controlled knee mill a bit earlier, it was everything Centroid tried to be but failed. Reliable,easy to program nothing locked. I don't know if Anilam are still around but if they are look at them
Joel, You may want to have a look at the Shadow control. It's made by
one of the guys who developed the Bandit control.
If you currently have Bandit programs they will be compatible with the

I really like the control. I run Win7 right at the machine console with our
solid modeling software, CAM and Centroid all together. It's a great workf
low. Everyone at our shop likes the control.
As to who you buy the control from, we started with Ajax, and they are a bi
t of a horse and pony show. We got bad advice (whenever we could actually g
et advice) and fairly pathetic support, which we requested only sparingly.
We then connected with www.cncsnw.com and Marc there was terrific. Very bri
ght and he helped drive the project home for success. While I was able to f
igure out the bulk of the conversion, programming the Centroid PLC for the
tool changer was pretty advanced, along with a few other details.
Stability is pretty excellent. I've never felt like the control went down f
or any fault of its own.
Would I do it again? Yes. Totally. It doesn't mean I think Centroid is a st
ellar company based on my interactions with them, but it's a solid product
and I wouldn't mind having a shop full of classic CNC machines converted to
their control, but ultimately I wish that there would be more competition
on the CNC retrofit market. It's unbelievable how many great machines get n
eglected in the corner or scrapped out because people think nothing can be
done with them. As to this lathe, it truly performs on par with new lathes,
and at a fraction of their cost.
