I thought it might be useful for reprap to plot dxf CAD files (as used by the open source QCad). I've been working on a python program today that loads dxf files and plots them on my repstrap. It's using the pyRepRap module so it should work with any reprap whichever electronics type is being used.
The program plotting to screen:
The same file being plotted on my repstrap:
The resulting printout (hard to see because its a photo of light pencil marks:
Made a bit more visible:
The pyRepRap module does not support synchronised movement yet, so at the moment only straight lines along either the x or y axis can be plotted. As soon as I have the sync going then angled lines, circles, curves etc should be possible.
I will post the code one I've tidied it up a little and made it more usable.
