Just two pic's about the flats. Remember that, depending on your lathe system, your results may vary in the end.
The pics provide for actual cutting / finished piece realtive to what your seeing in the program when you zoom into the pathing.
And watch out for those feed rates you input...........now your cutting !

ART,
Just some ideas on posting options, as usual, don't know if easy or difficult but here's some thoughts along with reasoning.

1. Be able to pick a pathing stop point along the Z axis ( mentioned before ). This allows you to break up a profile for machining at a low
level. It would be nice if it also had a starting point, but, keeping it simple for now.

2. Scale option. Use of program diameter ruler is rather restrictive. Once the code or pathing is done, have an option for scaling one or both
axes. This would be the equivilant of using the scale function currently available in Mach.  

Let me ramble on some.........
Let's assume that a user dosn't have any CAD ( you mention about later on creating a drawing utility ). So as an interim,I am thinking that a supplied cad drawing done to a scale of  1 unit, with a few basic shapes on it, would allow code generation equivilant to the what the current wizards would provide. Then the user could actualy build a rather simplistic machining operation up prior to and outside of LT via cut and pasting of code. This provides a lot of functionality ( non- automatic i may add ) but provides for some of the more complex operations which higher level CAM programs have built in.

Thinking for easy / lazy ways to do some things but not burden down your efforts in developing the program. So in interim it provides for manipulation by the user and responsibilty falls on them.

Just a few thoughts....

Dennis,
Where did you put it?

ART,
Here is my  first actualy cutting test using LazyTurn. Not bad at all. Didn't realize that no ARC coding was posted until it was done machining.
May be wrong, but need arc coding to get a real nice finish or an increased tolerance as that would minimise the straights around the ball.
You can see them in the pics.  Attached pic is  of rough, 1st finish, 2nd  finish, and completed piece.

I decided to do a quick new Appendix "A" and rough draft is attached.

ART,
Enjoy the sun. Will check the release out and hopefully finish some sections of the manual while your away.
But most of all just want to do one turning from it, sort of like taking the new car out for it's first ride.

Russ,
I get a 219 error with your combination shown in reply 1293 and LT shuts down then.
I don't think your missing anything as the rough and finish passes are reasonable.

Tried a number of different fines at or under .001 tolerance, no numbered errors.

FOR FILE IN REPLY 1287 / JOUST.DXF. Not getting any errors but fines are not right.

hudmut,
I use a hall sensor on my lathe and works great. It was much easier to mount / implement that an opto with a single slotted disc when i did my lathe conversion.  So have used both with success. For a pickup i used a rare earth magnet from Radio Shack ( about 1/8" in diameter ) and just cleaned a spot and crazy glued it to the back of a gear. You will need look up the max current allowed by the sensor and limit it to the the sensor via a resistor. Just needed +5v / signal wire back as an input in MAch / and a grd.
