where is cura bug report site?

Gene Heskett
Greetings all;

I think I have a cura bug.  I have now made 4 of the test for fit
bearings, stairstepping the size of the bb over enough range I should be
seeing the effect in how they fit.  But I am not. Then I noted that my
last openscad .stl was 93686k as delivered to cura.  But despite 2
overwrites, cura still thinks its 91 megs, and I just made the bearing
ball .01mm bigger which should have make the bb's fit a _lot_ sloppier
considering theres 72 of them.

That big an stl takes cura several minutes just to render a screen image
of it, but having it reuse the old, 91 megabyte file that no longer
exists, instead of the new, I can see it in mc, 93686k file, sucks, and
I've now wasted around 4 rendering hours building old code with a
stairstepped bearing size with no effect on the plastic produced. And I
want to report the bug.

Cheers, Gene Heskett

I'm not a cura user, but could it be that cura considers a meg as 1024k?
If that is so that 91 megs are 93184k.

When you save the revised stl file, give it a different name. If you've
generated it in opnscad, just because you have made the objects
physically larger, does not mean the file will be bigger, it can consist
of the same number of triangles. Depending if you're buying or selling,
a KB can be 1024B or 1000B. My version of cura, shows the standard
windows explorer file window, but if showing more than 8 lines, it
replaces the bottom few lines with a summary of the selected file,
showing size in MB, and if you are not careful, it goes to full screen,
which becomes a real pita to change it back. Absolutely no point in them
trying to be different then the standard file explorer interface.

I am now deleting that .stl on the cura running machine BEFORE I copy the
new version across the cable to it.  And that seems to be working, the
last printer render showed some improvement in the fit.

So I've got another try warming up, that has a .02mm bigger ball groove.  
Even if its still tight, it may be good enough for the girls I go with
by the time its greased.

Thanks Ray.

If you’re stairstepping this 4 times in increments of 0.02mm as you referenced in another message, you have a total increment of 0.08 mm which is literally a hairsbreadth, and you should in fact not expect to see any difference in sizing or fit — even if your printer were capable of producing prints with that level of dimensional accuracy (which it probably isn’t).
