Hi Terry,

Open Ultra Master Help file and look for "Setting Ultra Master Advanced Mode". This will tell you how to access the advanced features of Ultra Master. Custom motor creating is one of them.

Regarding the sensors, the Chiron has them on the cylinders, there is a cylinder for each tool, each having a prox sensor top and bottom and then two more cylinders either side that lower and raise the basket.  It looks at first a very complex set up but  when you study it is actually quite simple and seems reliable as the only thing my friend has had to do in the 15 or so years he has had it is replace pipes as the originals started splitting.

Heres a vid of the style on the Chiron.

That's one cool tool changer. Definitely the fastest I have seen.

If the basket can't rotate then setup is not an easy task, trying to reach the tools on the rear.

Thanks, Hood. That sounds really good! Got two Cincinnati machines (a mill and a lathe) awaiting retrofit and I am quite convinced now that the CS Lab controller is the way to go. Although the delayed pullout in threading would a be a problem on the lathe. Hope it gets sorted by the time I get to it.

Feels better than with the SS?

Yes. Just remove that part.

That's bad news. That macro won't work then. You have to move in absolute then. Consider the macro that Hood suggested you at the beginning.

Hood,

And will you just make a new A type spindle nose and permanently attach it to the current spindle? Or will you make new the whole spindle with the nose?

I too don't like the threaded spindle on my 9x20 and had the same problem with the chuck tightening up while I was tuning the servo. Took some serious effort and fair extension to the keys to unthread it. Have also been thinking of making a new spindle for it, but haven't yet decided how I want it. If you have ideas would be interesting.

It shouldn't. The moves are incremental.

If you want to reset the A axis after a tool change, just add this line to the end of the macro:

SetOEMDRO 803,0

Only reason I can think of is mechanical. Could be that the motor locks the turret so tight that when you command the next tool it loses steps trying to accelerate. Try decreasing the speed and acceleration of the A axis in motor tuning to some real low values ( I would say at least 1/10 of the current values) and see what happens.
