two knotworks

two knotworks

The upper one is a single-pass carving. The lower one is two pass, once rowwise then once columnwise. The Gcode for these was created using an svg file found on wikipedia. * rendered the SVG (using firefox, even) * pulled it into The Gimp and selected by color the figure. * 'feathered' the selection by 20 pixels * flood-filled the selection with black onto a new layer. * merged that layer down with a white layer * inverted the result (so it is a sort of glowing white version of the figure on a back background) * pulled that image as a jpeg into the ENC Axis image2gcode program, which made the gcode * cut it with a .16inch ballnose bit. (please ignore the flaw on the second carving...I messed up homing the X axis the first time around... oops.)

Man, the result is very nice for wooden machine : ) Could you adjust the step so it can be even smoother?

I suspect so. These are only my third and fourth 3d carvings, so i was more going for speed than finish. I could also use a smaller bit.

poppycock!

That would be sort of cool to try, though. the image-to-gcode program i am using will only read jpegs due to a bug even. I have been saving them at quality-100 to try to avoid any artifacts.
