Output Manager crashes when generating 2D dxf

[Carlos Azevedo]

I've created a gear train composed of 4 spur gears with a module of 0.6185, with the following gears:

Gear 1: on shaft 1, 10 teeth
Gear 2a: bottom gear on shaft 2, 46 teeth, driven by gear 1
Gear 2b: top gear on shaft 2, 10 teeth
Gear 3a: bottom gear on shaft 3, 50 teeth, driven by gear 2b
Gear 3b: top gear on shaft 3, 12 teeth
Gear 4: on shaft 4, 56 teeth, driven by gear 3b

Saved the project then tried to output all the gears to 2D dxf; the program crashes (real crash, no error message) on gears 1, 2a and 2b.
I then recreated them one by one on an empty project and successfully output them to dxf.
The only parameter I've changed was the 'gear point dist', that I've changed to 0.005. The units are metric.

Carlos:

  Thx for  the note. Can you send me the project so I can see if it crashes here.
Ill be using new code in future for DXF's I think, but Id like to see if I can fix that one up
in GM as well.

I had the same problem with 2D-DXF running elliptical gears, then ran a 3D-DXF and it worked correctly - unfortunately my CAM wants 2D. I also tried G Code and that worked. Went back to 2D-DXF and it worked for one gear (the more complicated one) but not the other, and now instead of crashing it hangs showing about 1/3 progress on the bar.

Tried a test with the basic default spur gears and the output worked correctly.

Tell me how to attach a file or give me an email address and I'll send you the gprj file (I assume this is the one you want).

Hi:

To attach a file, just hit reply to this post, and on the bottom is a checkbox called "Additional Options" ..
click it, hit the browse button to find the gprj file and it will attach to that post.

Thx

The file should be posted.

Running a few more tries to help you nail down the problem. I downloaded the new development version 4.890, same problem.

I redrew the project (it's only two simple elliptical gears - and its just a test case) and it worked. Not sure what is in the gprj file but perhaps it corrupted somehow.

[Jabs1542]

Ok - it worked, sort of.  When I recreated the first (simple) gear I could get Output Manager to create the DXF file. This is basically all I was after since I already had a DXF of the larger gear. But when I recreated the larger gear I can no longer generate a 2D DXF for the smaller gear - but I can for the larger gear.

I have attached this file as well.

Hi:

  First file I can save dxf's on both gears. Second file seems corrupt and will not load at all.
Ill keep looking into what can corrupt them in that way, since its switching gears itr must be
some setting in the setup Im thinking.. just cant think of what.

Art,

I tried again today, started from scratch, and everything worked correctly! Exported both gears as 2D-DXF files.

I posted the file in case you wanted to see if there were any differences with the other files.

Off to cut gears  ;D

I am having the same problem with Gearotic crashing while trying to generate an escapement.

I will attach the project file to this post.

My windows XP boxes don't give much feedback, but my windows 7 gives this additional information:

Thanks,

I just found an interesting corner case to this problem: if I generate a 3d-dxf file first, I am
able to generate the 2d-dxf file. Otherwise, the 2d-dxf generation makes a hard crash...

Thanks,
