Hi,

EMC has the ability to read in GIF files and convert to g-code, I can't find a comprehensive reference about using but I have a simple question.

I tried importing a very simple share (a square), the GIF image has only two colors, white and black. The border is black, EMC converted to a g-code of engraving the square, now what are the options to just score the borders of the square? I don't want any milling inside the shape ?

I'm trying to get some simple shapes from image files and score them off some sheets

thanks
Sherif

Image to G Code was not designed to just cut the borders of shapes. AFAIK it will cut the entire image only.

It would be a simple task to just write the g-code to cut a square.

And there is not much more info than is in the docs that I know of for image to g code. I assume you read the docs? You might look on the wiki site there might be something there too.

square was just a test case I created, but it seems that a better alternative is if I can get the shapes in DXF then convert to gcode

You could try G-code tools for Inkscape too (in comjunction with Inkscapes image-tracing).

But don't ignore the possibility of simply writing G-code by hand. As EMC2 G-code can include loops and conditional statements it is pretty powerful.
