  Sorry, what size tool is that, I cannot repeat it.. and depth/pass and clearance?

Thx

Rich:

  Sorry, that wasnt the bug I was talking about. When I loaded it, my depth per pass was larger, and then the issue I was talking about happens, the left side goes away entirely.
Im still looking into your issue..

Hi:

  This one is the result of an unwritten rule ( till now. LOL )

Rule: Any rough profile must be possibel with the first pass being a full length cut. Stock must be set large enough in
dimater to allow this. To see what I mean, use the Diags checkbox in the rough generator to see the diagnostic lines,
note how the first pass is broken. Increase the diamter enough that the first pass is a solid line.

 This has to do with soem complexities in the reentrant iterative algorithm I wrote for the path calulations. I may revisit at
some point, but at the moment, to ensure the "tree" is correct, the first node ( line) must be a complete line.

 ( For the mathmatically inclined that probably explains a bit about how Im doing this.. )

Simso:

  You have to be carefull to not go below zero is all. Send me the one that fails if you feel it IS zero at the tip. Ill see whats up.

  As Chip says, the ragged green line is only indicative of too fast a feedrate on a small object, Mach3 then cant keep up the display smoothly.
Thats not an issue with LTurn really..

Rich:

  Loaded tap file, ,doesnt look bad to me.. what do you find wrong with it?


>>Tried LT on three more computers:
>>FPC#1- 3 GHZ / 1G RAM - CUSTOM- XP PRO SP2 -----------NO PROBLEMS

  Good..

>>FPC#2- 900 MHZ / 256 RAM - LAPTOP- XP PRO SP2 -------WON'T RUN ANY VERSION AFTER DEC 17

 Dunno why.. When does it error out, last version seemed to fix up the openGL failures on other machines..

>>FPC#3- 3.6 GHZ / 1.5G RAM - EMACHINE -XP PRO SP2 ----X POINTER COLORS ARE LOST

 Thats a weird one.. video hardware accel maybe? Seems an openGL implementation issue, cant repeat it here at all, and cant think of
how to check it any. I basically tell it a colour, and it shoudl be correct.. all kinda Windows magic from there..

Hi:

>>Hi All,
I just D/L'd the zip,and now cannot get anything to load. I should say I got one to load,and then get a file is - in and cannot load,moved it around,and still cannot get it to load. Tried different dxf's and all that I have done,still cannot load

  The profile you show is bad, a profile doesnt have top and bottom, only the top.. see the examples posted in the threads..

 You mean the posted GCode is offset?

Hi Dennis:

>>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.

   Can you show me the dxf, and a screenshot of the toolpath as well as the Gcode produced. I'll get you an answer as to why its happening. Its likely some bug in my Gocde output more than the profile generation, perhaps my radisu/diamter not working or soemthing..

Thanks

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.
