Steve,

Smooooooooth as a new baby's you-know-what.  Nice!  Can't wait to see it running full-speed!

Hood, can you tell me if there is a low power (say 100 to 200 watt) version of the AB drive you are using for your turret that might have identical features to those that you are taking advantage of?

I am using my spare 400 watt Mitsu J3 for the arm and I purchased a 200 watt Mitsu J2S for the turret. The Mitsu does have programable motion, but it is incredibly convoluted process to set up. From what you describe, the AB is very straightforward.

The smallest is 500watt, 2.5 Amps cont 5 Amps peak.
The models to look for are
2098- DSD-005X
2098- DSD-005-SE
2098- DSD-005X-DN

The first is the Indexing drive, second is sercos but if you disable that it turns it into an Indexing drive, the last is the Indexing Device Net version.

There is also
2098- DSD-005
2098- DSD-005-DN
Neither of these support Indexing.

Sorry but I support Tormach's policy. It would be the same if I bought a new car then took it apart to change engine parts to make it more sporty and more HP. 

Of course you would not because you want to sell the Owners something. (;-)

AGAIN we should just agree to disagree, (;-) TP

You analogy is far off the mark, I'm afraid. There is certainly no shortage of disagreements between us, but in this case it would be imaginary. We would be disagreeing on whether the number 2 or the color red is the best flavor.  It is obvious that you missed the point entirely.

It matters zero to me what your opinion of Tormach's policies are, but it does matter that you present your speculations about me as if they were facts. You may have noted that when I am speculating, I say so plainly. I think that would be a good policy for you to support.

Thanks! I'll check them out.

500 watt is major overkill for my little carousel, but if the price is right, it would probably save enough time to be justified.

I think your own words sum it up nicely.  You were disappointed that Tormach would not work with YOU to develope 3rd party hardware to run with a standard TORMACH. (;-)

I don't care to get into a Tormach debate, but I do want to clarify one thing. In my inquiry, did not suggest Tormach change their policy (regardless of how condescending *most* people think it is). I offered to spend MY time reconfiguring MY software to eliminate any possible conflict with their setup, and that no Tormach customer needed to be involved nor inconvenienced nor given access to anything. The process would be one engineer (me) consulting with an other engineer (Tormach's) to provide QC for the benefit of Tormach owners.

Their response (again in writing) was that they are " . . . not excited about helping third parties, particularly those [who's products] compete with Tormach's".  They inked me to their 'Duality Lathe' as if that was in any way competitive with or equivalent to the InTurn™. My current controller also accommodates a servo driven spindle with universal hard tapping macros included. Tormach has no equivalent that I am aware of.

The simple solution is to ditch the entire Tormach setup and do a fresh install of MACH and put the InTurn™ stuff over it. Tormach only succeeded in aggravating their own users  . . and me. I am asked a couple of time a week what machine I reccommend for use with the InTurn™ 4th axis. Venture a guess?
