Hi:

 no, thats my actual hand..

 I suspect its my math more then reflections.

Hi Guys..

  Just so you can see how collision detection changes a toolpath, here is a sample output of latest development version...

should work if you just enter .01 as the ball size.. and leave the data alone..
hard to say though.. I did design it in mm's.. Ill list a check for it in my schedule...

Hi:

  There has to be enough samples, and not too many.. The ball meshing takes one number , the diamter of the ball, what it does is rotate a ball of that diameter across the points, and when it rests on 3 points, it makes an edge of a triangle. Usually, 1 - 4 mm is the right setting for it, but you may have th edecimate the cloud some to get it to remove enough points to allow it to work.. no secret to it.. just a lot of playing around..

Hi:

  Yeah, gotta watch that infra red stuff..

 You cant turn it into Gcode using Mach3, but MachCloud will create a 3d stl file for you, CAM programs liek Vectric will then create GCode..

Hi:

  Yes, basically you just plugin a webcam, but the laser source is also needed.. other than that Mach3 handles the rest. Pretty experimental though.. results vary by how dedicated an experimenter you are. Fun to play with though..

Hi Dennis:

  A play version of LT is in the FTP site. The downloads page of the website has a link called "More information". Click there..

Graham:

 Thx, I have them now. The queen woudlnt load due to a arc in there smaller than the connection tolerance. Ive done a bug fix and that is now sensed so all of them look nice now. They seem to rough well as well, so I suspect collision detection will fix up their paths to be perfect.

 Chip: I have the test file you uploaded, I see it fails the load, Ill find whats wrong. You know the load failed if you dont get a spun profile immediatley, if you do get one, then the load worked fine.

Thanks

Hi Guys:
 Thought Id post a short video showing how LazyTurn is coming. This shows the roughprofiling before collision
detection is implemented. Turning is definitely hard on the head to code for, but the toolpath seems pretty good from the roughing algorithm, next I need to add a tool geometry collision adjuster to make the path right to the tool, at the moment the path is correct only to the tool's reported tool tip radius, and while the simulation is wrong since it doesnt take into account that radius in the 3d generations, the path is correct and seems quite efficient for any radius tool held by a toolholder that wont collide with the object. Hopefully, collision wont take me as long as the pathing.. but it sounds hard, so I wouldnt count on it.... :-)

Hi Rich:

 Wish I shared the hope. :-)

Seriously, it is a slow project as its much more complex than youd think. However, I hope to learn many new methods that will help
make mach3 better itself. Its all about educating myself. Progress continues..

Thanks
