A little help with error

Сообщение rray » 28 янв 2011, 00:47

Post-processor: Scale factors for X and Y axis are not the same. G02 and G03 codes will be corrupted.
I get this while running gcodetools on the attached file

What post-processor have you added?
All preferences of extension are not stored in the svg, they are stored in Inkscape's config.
Can you post a screenshot with preferences tab opened?

Ok, now I got it. Postprocessor "flip" uses another post-processor "scale" which gives "G02 and G03 codes will be corrupted." But it should sound like "could be corrupted.".

Have you tested the Gcode?

By the way why are yuo using post processor? Is it really needed?

And where did you get those path? It's kind of strange one. It consists of more than 1000 small paths. There could be a problem to machine it...

About a circle it should be exact circle this is what I get:

no, it looks unusable without a lot of editing

By the way why are yuo using post processor? Is it really needed?

If not orientation and tools are upside down and mirrored

And where did you get those path? It's kind of strange one. It consists of more than 1000 small paths. There could be a problem to machine it...

I see...

Set up minimum arc radius at the Options tab to something like 0.001.

There's a problem to set a default floating point value with the Inkscape extension. Because in some locales it should be "0.1" and in others "0,1". This bug was fixed for newest versions of Inkscape, but as Gcodetools being used with different versions it could appear some times.

By the way you could use separate "Path to Gcode" extension instead "All in one". It has smaller window and all functions that are needed to Export path's to Gcode.
