Hi Guys:

  Some DXF's drawn primarily with arcs do generate goofiness, its not the DXF< its LTurn having trouble figuring out whats inside and whats outside.
Im working on solutions, but till then playing with numbers as youve been doing is the correct way to go, its all incredibly complex to do some of this stuff,
cant belive how bad it truly is at times. LOL..

Hi:

  It did used to simulate, but what it simulated was the removal of stock material, thats a function of the intermediate roughing step which I discontinued for now till I get finiish
profiles. That new button wasnt a joke really, its just not yet finished. ( Some of my buttons during development get downrigth nasty LOL, so finish test profiles may come along soon if my theories hold to be true. :)

>>However how long are we looking before you guys release a commercial version with a finishing toolpath included.

  It coudl be awhile. ( A LONG while.).

  I do intend to do a finish profile next, so at that point, if you take great care, you could cut jobs. It may not be too long before it at least outstrips lazycams ability, it already does in some respects. But as a hobby project I set no timelines, I suspect it will be buildiong over time for a long time, but I do wish to get it cutting profiles at least in the near term. The intermediate step between rough and finish is actually the key to completion, its a very hard step to do, but will add quite a bit of capability in terms of keeping it easy and lazy, which is a primary concern for me.

Hi Guys:

 Unfortunatley, its a "feature" of the library I use to offset the contour, it doesnt have rounding of sharp tangentl breaks, so in a very sharp tangent, as you can see if you use the diagnostics output, the point gets very far away from the original profile. Such is math. I will look for a solution internally when I get a bit further, till then increasing stock is the only way. In the end I just need to modify the algorithm some to compensate for it..

Hi:

>>About the other problem...curve to a sharp point (pic).
Did you get yours to break like here ?
It actuall posted code OK but there was NOclearance for the flank at all.


  No, for some reason mine is fine using those values, I get the expected tool collision avoidance..
 
  I have been making changes in mine though,so just to be sure, here is the development version Im using ...

RC:

 Depends on the insert and the feeds. In the end that rear flank will be taken into account, its just at the moment the development hasnt got there yet. It requires a dual gouge sensing to sense
not only a gouge to the profile ( currently working) but a gouge to the leftover material. ( Not yet implemented.). So when I say "On purpose, its better put " As yet."  :)

 Ohh, I see what you mean.. thats on purpose though, its assumed the tool can cut on either edge of a tool.

RC:

  in 12.47.gif, thats what Id expect to see. The profile follows the tool inward, so there shoudlnt be any trailing edge hit in that case. The photo looks good to me?
