DDSCV1.1 3 and 4 axis offline motion controller

That is the problem, lathe is a very small market compared to routers and mills.

However it's a problem that I can't understand in some ways as we could thread with the Conect / Boxford / Denford machines on DOS and now we have far more powerful external motion controllers and computers but no one seems to be able to get it right out of the box ??

As John says, lathe is only a small part of the market. I can't remember if it was Art or Brian, but I'm sure their upper estimate was 10% of Mach users used turn, but more likely near 5%. And Mach is probably the most popular option for Turn applications.
.
I'm not sure why threading is so hard. I suspect the problem is how more modern controllers have been programmed to handle general motion, that when they get around to adding threading, it involves major changes, so it gets glued on as an after thought.
I'd guess the old DOS systems were a pretty basic system. Move x steps each time there's a pulse from the multislot sensor, adjust timing slightly if too fast/slow, and you have a thread. The benefit that style of controller had, was the hardware and software was the responsibility of one entity, and you didn't have to program in lots of different options, along with all the other usually pointless functionality that users think they must have.

Well it's got to be better than paying $200 for a license based on advertised functionality only to find they might make it work this year, next year, sometime, never.

If a few more of the developers of linuxcnc were experienced engineers and could see past their own assumed level of knowledge it would be the only option at this point in time ;-)
