Hi Art,
before you get too deep into the structure of Lazyturn can I drop in a few ideas :-
1. Can we have the option of front or rear turret, better still a mixture of both. I have external tools on the front and internal tools on the rear.
2. Can we have centre line drilling and tapping with graphics, user to enter drill/tap dia and length etc.
3. Could we have a scaled plan view, backdrop of our lathe layout, that way collisions could be spotted (users could draw the plan view as a dxf)
4. Would user defined tools be possible, tool and turret could then be drawn for above.
5. Could you make it so that grooving/parting tools can have 2 offsets, one on the front edge and one on the back edge of the tip. This is great for sizing grooves and maintaining position.
6. Is it possible to do X axis threading, e.g. lathe chuck scrolls.
Some wish list I know, but if you don't ask, you never get.
Graham.
