Unofficial Python library for working with the AxiDraw v3 pen plotter.
- control AxiDraw v3 directly from Python with a simple API
- convenient command-line utility
- constant acceleration (trapezoidal velocity) motion planning
- path drawing order optimization
- drawing transformations
- translate, scale, rotate
- scale and/or rotate to fit page
- move to origin or center of page
- preview drawing (render to png)
- turtle graphics
Command Line Utility
pip install'd, you can run the axi command-line utility. Here are the supported commands:
axi on # enable the motors axi off # disable the motors axi up # move the pen up axi down # move the pen down axi zero # set current position as (0, 0) axi home # return to the (0, 0) position axi move DX DY # move (DX, DY) inches, relative axi goto X Y # move to the (X, Y) absolute position
- circles, arcs, beziers
- svg support
axi is not yet available on PyPI, so installation works like this:
git clone https://github.com/fogleman/axi.git cd axi pip install -e .
Of course, installing in a
virtualenv is always a good idea.
Then you can try the examples...
Use the turtle to draw a dragon curve, filling a standard US letter page.
import axi def main(iteration): turtle = axi.Turtle() for i in range(1, 2 ** iteration): turtle.forward(1) if (((i & -i) << 1) & i) != 0: turtle.circle(-1, 90, 36) else: turtle.circle(1, 90, 36) drawing = turtle.drawing.rotate_and_scale_to_fit(11, 8.5, step=90) axi.draw(drawing) if __name__ == '__main__': main(12)
