Hi there, 

I am very much an Inkscape amateur, i recently purchased an AxiDraw V3/A3 plotter. I create geometric art where the shapes are filled with lines, which i used to do by hand with a ruler and hours and hours of my time. I create my designs in Illustrator before importing them into Inkscape where I individually hatch each shape using the axidraw hatch fill plugin and what i am finding is that with vertical and horizontal hatches or ones that are close to that angle are fine, however ones of let's say a 45 degree angle it seems to put two lines close together and then leave a big gap and then two lines close together (which is not what shows on screen in inkscape), sometimes it's only part of the shape that will come out like that, sometimes it's all of it, and if i replot the same thing they come out exactly the same. At first i thought it was a problem with the plotter itself and speaking to axidraw i have tightened up some parts that were loose but i am still getting the same issue. This morning i ran a test where i decided to make a bunch of evenly spaced lines in Illustrator and then rotated it at different angles, I then imported it to inkscape and plotted it, it came out perfectly which leads me to think it's the hatch fill in inkscape rather than the plotter itself. I don't want to manually hatch everything in Illustrator beforehand as that would take hours. I have attached some examples the file cats is one that's perfect, vertical and horizontal line only. The one titled problem is a test done in inkscape where you can see the lines banding together when on an angle. and the other two titled rabbit 1 and 2 is a piece of artwork where you can see clearly areas where two lines have grouped together leaving a bigger space between. 

Has anyone experienced this before? Am i missing something with the hatch fill tool? or is there a better way to do it? 

Any help is greatly appreciated! 

Thank you

This really has nothing to do with the Hatch Fill extension; it's a mechanical issue on this particular AxiDraw unit.
