Drag knife compensation combined with tool offset about heekscnc

[GoogleCodeExporter]

Drag knife compensation seems to work ( I've only tried simple cases ),
by adding this code in the profile() function in kurve_funcs.py

    offset_curve.OffsetForward(0.5, True)

Adding it after the curve has been offset, so that the tool radius and 
offset_extra values are also used. So the code looks like this.

    if extend_at_end > 0.0:
        span = offset_curve.GetLastSpan()
        new_end = span.v.p + span.GetVector(1.0) * extend_at_end
        offset_curve.append(new_end)

    offset_curve.OffsetForward(0.5, True)

    # remove tags further than radius from the offset kurve
    new_tags = []
    for tag in tags:
        if tag.dist(offset_curve) <= radius + 0.001:
            new_tags.append(tag)
    tags = new_tags


I hope this helps.
Dan.

Dear Dan,

thank you very much for, this is good news!

Unfortunately, I cannot get any result by doing the changes in the 
kurve_funcs.py file.
I tested very basic shapes, but the resulting g-code contained only the normal 
tool offset.

Is it necessary to recompile HeeksCNC?

Thanks,
Felix
