magic spring (Slinky)

THERE IS NO STL(except when i'm waiting for updates to take effect, and have not deleted the stl again(thingiverse refuses updates without a recognized file format))
I wrote a java program that outputs directly to gcode.
to customize:
update 2022:
spring22.jar, recommended settings to start:
inner radius, 30 is a good starting point.
outer radius, larger than inner radius, preferably by 4-6mm.
layer height, I recommend starting with 1, or 0.8
zigzag per nozel, start with 2, larger number(3-5) if trying for extremely small/thin slinky.
temp, basically as cold as your plastic will flow, 160-190 for pla, 210 for abs(edit gcode to raise bed temp for abs)
extrusion multiplier, i usually sticl with 0.9, but 1 actually works.
NOTES:
code homes before(and after) heating. don't be concerned with immediate movement.
If you are outside the US, and your language formats decimal numbers with comas instead of periods, I'm working on a force to English format code, and will update when i
