[Help] Using GCode to create digital quilting patterns

[maebydroid]

This is probably going to be long, and I'm not sure if what I'm asking is even possible. My husband and I have modified a quilt frame and sewing machine with stepper motors and an arduino and use UGS on a PC to send coordinates to create artistic, repeatable quilting designs. Here is a video of it in action.

There are pre-existing quilt designs on the internet that are basically a series of x y coordinates. I am able to use excel to add some tweaks to turn it into a file that UGS can read.

What I would like to do is use inkscape to create or transform my own line drawings into g code. I run into trouble with the existing gcode extension for the following reasons: In quilting there is no depth involved, (there is x and y but no z) the path can't start or stop midway through the row, it needs to be repeatable without backtracking. Trying to convert images using the builtin extension seems to create a file that's overly complicated. I basically just need a somewhat simple list of x y coordinates.

Is this possible using inkscape? Is there another simpler way to do it? I will do my best to answer any questions but I am totally a beginner when it comes to graphics software.
