customer is not real pleased with the control. I believe he had tool
compensation problems that were unresolved, and I don't know what
kind of support Ah Ha has anymore.

As far as I am aware and hopefully someone will correct me if I'm
wrong at the moment only Ahha and Microkinetics can do spindle
encoding and therefore threading.
There are a lot of folk out there using Ahha on lathes in a fully
commercial enviroment. It may be well worth asking for some advise on
the tool compensation.
I don't use or run CNC lathes so can't comment but try aking this
question on http://groups.yahoo.com/group/ahha_cnc
