Chip,
I get the same results as you. I have back plotted a number of the files, rechecked them in CAD and found things to be darn close when you wanted a very small clearance. Don't have time tonight but maybe tomorrow i can try fooling with it.   

The measuring capability using the crosshair is much improved over the pointer.

Hi, Rich

Just using the values for testing, Don't wast time on it I'm sure Art can see them now with the bigger drawing layout and latest pic's. 

Thanks, Chip 

Hi Guys:

  First pic was correct, just looks funny due to large pullout.. Second pic is wrong, its missing the other side.. Ill look into why.

Hi, Art

Not wanting to argue, But the 0.5 rough looks different to me and the G-code say's it is missing a Left rough pass also. 

Even this Cave-Man can See It, Chip

Hi Chip:

  Sorry, I was talking about the lines generated only, the posting is still just rough code I threw together to test code output, it isnt necessarily right, the photo of the calculated lines is correct by the look of it to me though. While one phot was missing the left side, the other looks fine. The posted Gcode may be rigth or wrong, its just test code and isnt very well done at this point. Im still just focusing on the actual job generated as the displayed lines, the code is a separate issue..

Hi Guys:

 The reason the left side was missing was that the intersection calculator saw a scan line hit exactly on the line of the profile.
This means the lines dont so much intersect as overlap. This version fixes that problem in that instance. It also takes care of the
memory leak I belive. Gone here anyway.

Hi Art
What i fund in the LT code and i hope i can explain this well enough the billet is 15.91 MM and LT is set for this Dia next the profile is 10 MM at the smallest dia and LT shows this with the arrows when the cursor is over them and with a .5 MM per pass cut the code is generated with a + 4.5 MM to the actual billet size and therefore when the profile is cut it leaves this excess on the turned part so when the machine first starts it cuts air before ever hitting the billet i understand that it is a roughing code but if i tell LT to leave 0 on the part why is it leaving 4.5 MM i would think it would leave .5 MM or even 1MM but 4.5 MM that doesn't seam correct.

Hi Art

Memory leak gone here , still get a tooltip failure with a tool 0.1

Is this Vista realted (new box and never tried LazyTurn on this one)

sgCore.dll not found

Cheers

Hi bengt

First download Lazycam, put it in the Mach3 folder then download Lazycam update, put it the Mach3 folder then download Lazyturn, put it in the Mach3 folder then it should work.
