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?
