"Drawing out of range" with negative coordinates #16
Description
My plotter has (0, 0) at the center, so I want to be able to use negative X and Y values. So I set Left and Buttom to negative values. Unfortunately this gives my a "Drawing out of range" showing coordinates that are NOT.
I had a look at the code, but I couldn't find a obvious reason.

I found the problem:
scale.offset = (plotter.xyMin[0],plotter.xyMin[1])
breaks
scale.scalePoint(point)
for negative values.

Does your svg file have negative coordinates?
TheNitek commentedon Sep 4, 2019
Yes, because my plottable area is -40 to 40 in both directions

Have you tried using positive coordinates and letting gcodeplot offset it to the negative area?
TheNitek commentedon Sep 4, 2019
No I didn't yet, because that doesn't seem to be available within the UI. Also I find it to be more intuitive to have the same coordinates in Inkscape as on my plotter.

That's I think the source of the problem: the plugin automatically adjust the drawing location so that the drawing's 0,0 corresponds to the minX,minY on the plotter.

I think this is a bug. This program should be looking at the min and max coordinates of the SVG, not assuming they are 0,0.
