GT2 3mm Pulleys

Art,

Thanks for the thoughts.  I can understand wanting to do it right.  I will give the 5-3mm conversion a shot.  If you do get the info you need to generate the tooth profile, I will also look forward to that.

  They are in todays release, BUT be cautious, they look a bit off to me, might not matter, that happens in interpolated data,
but let me know how they stack up.. Thx for the pointer to the data...

Art,

Thanks!  I will generate some gears and let you know how they work.

UPDATE:  Tried to generate a 10 tooth gear - yes pretty small.  It looks like a series of vectors that don't quite tie togehter.  I will try to attach a PDF of what the DXF looks like.

When I try to generate a 25 tooth gear I get a Error Found Gearotic:11, Attempt Recovery? - I tried several times to recover and it just loops around to the same error.

Paul;

Have you tried switching over from inches to mm in your setup?

  I did discover inch mode wasnt working, a fix was generated so redownload and you should find its fine..

Art,

After too much business travel got back to the gears.  The profiles look a bit flat on the tips compared to the other GT profiles.  When I cut a 55T gear, the mesh was off with the 180* of engagement.  I went to the GT2-5 profile and re-sized it to the proper diameter and it seems to be working fine.

Thanks again for the effort on this.  It is pretty nice to be able to knock out a gear for a project as needed.

Now that the rotary is complete, time to get back to the clock!

  Yes, tyhe shaping can be difficult to get right  if the spec isnt just so.. Its why I always hesitate to try to
duplicate a shape unless I have something more definitive. The GT2 I did was based on a belt apparently, so
I expect its a bit off. Ill wait and see what feedback occurs over the years.. :) , eventually Ill find the
right data. Glad to hear the 5mm works when scaled.. Maybe Ill just change the code to scale the 5mm ..dunno why I didnt
just add it that way..
