Hi All:

  First, thx for the testing. The feedback led me to the solution. I think youll find it should be
fine now. While I see no difference in runtime action, it turns out I was asking for vertices and index buffers
I had sent to the graphics card as buffers. Turns out this is a no-no. It wont fault a program, but some
video cards seem relaxed enough leave the old buffer alone, others zero it. I suspect system memory total
is the deciding factor if the buffer got overridden.

  I now keep a local copy and export that to output. Seems good and I have high confidence ( famous last words)
that the problem has been fixed. Thx for the models and clues, it woudl have been very difficult to find any
other way in the circumstances.

New version is online now.

Thx
Art

Happy to report I can not break it.  ;D


Thanks,

Well...I broke it.  What I was doing before...just a simple bolt and nut worked fine. Then I started fiddling with some other options. I tried a spherical head on the blot, but standard hex nut. Worked fine. Then  changed the nut to spherical....the display % counter stopped at 33.33% and my system slowed to a crawl, to the extent I had to reboot. Restarted and tried again, with the task manager running.  Both CPU and memory were pegged and memory for Ticker kept increasing at a fast rate. Was able to exit the program this time, though. Then tried again this time with "none" for the nut. That caused the program to crash.

Both are probably easy fixes.

thanks...nice program. I haven't printed anything yet, but the bolts I have created now import fine into my slicer.

Thanks Randy:

Still some little bugs in there for sure. I think the sphere may be trying to be too hi res and slowing you to a crawl.
Ill work on that. It tries to keep resolution very high as  sla printers can work with very small sizes. It Automatic
but not quite that smart yet.

  Also, just an FYI, blender will not open the objs, not sure why yet, but Cura, and meshlab have no trouble.


Thx again

I was trying out the complex shafts to create a joined left/right thread with a nut. The shaft generates but the nut seems to have a problem.

I have attached the files. Am I missing a setting?

Thanks,

Andy

Hi Andy:

  If you select your first section, youll see the setting for "flats" is smaller than the shaft diam.
The "flats" is the size of the wrench for that nut, slide the flats larger till the nut is large enough.
That will fix it.

Thx

Hi All:

  Just a note to those that may have tried ACME screws, there was a bug I just found that made their tooth profile
wrong. It will be  corrected in the next release. A Mod4 helical spur gear should work on a 4mm pitch acme screw
as a worm gear pair and I noticed the profile was very wrong for that.

Thx
