Path generator for line art?

I want to generate some 2D patterns where I have more control of the actual nozzle path, rate, extrusion, etc. I could make a 3D design that has very thin width and height and assume the slicer will path it out correctly but that seems dumb.
Any kind of software out there for this? Something that might take a dxf or svg file for the path and allow me to set dynamics like speed and extrusion thickness? I need to generate test patterns but trying to write it all manually in gcode is so much work
I want to do some repetitive but simple line-drawings tests to experiment with extrusion qualities and to fine-tune the dimensional accuracies.
thanks

this is likely to lead you in the right direction. you want to search for things that do gerber files

[reprap.org]

and the drawing reference as line art. this should get you going!

If u have a image of the pattern you can do it. from image to paths , paths to 3dobjet and then Slicer and modifier meshes. With modifier meshes you can "split" your model and modify some parameters of different parts.

I do this from a image.

Sorry for my English.

Sorry. I change it to public.

Take a look at inkscape!
[www.inkscape.org]

plugins and add ons will generate g-code that you could feed to printer

Generally does .SVG but can export to most file types

Generate path native and path extensions and plugins will do it

Google search a wonderful wealth of information???

The opensource.com link has one wash the file through TinkerCAD (closed source), while the Inkscape link is to a tool which AFAIK only exports G-code intended for milling, so one would need to add the extrusion parameters manually.

Easiest way I know of to get from a vector file to a 3D print file is:

- open in Inkscape
- export to OpenSCAD using one of the plug-ins for that ( [www.shapeoko.com] )
- open in OpenSCAD, tweak thickness
- export to .stl
- slice

I'd love to know of a simpler technique --- one which actually supported arcs / curves would be great, but I suspect the mathematics for that are problematic in terms of the processing time involved.
