Grumpy_Mike:
What sort of errors?
I have used Inkscape with a Gcode plug in to convert text into Gcode for engraving. However it does produce some gcodes that are not implemented by a lot of rep rap controllers?
If you look at the Processing section of my site I have some Gcode generators and viewers for PCB engraving.
I think you are right.... I think ink scape just produces some code that is not processed by the reprap code
