Hi,
Code looks great but I got problems to run it. Here the warnings I got

I hope you could help me to resolve it, thanks

I am running python 3.7.4 on windows 10 and I get a load entry point error, which I have no idea what it means.

I got it installed on windows 10/anaconda 3.7.5. Just trying simple commands like axi goto 30 30 send the arm carrening to its full limts out until the motors reached their limit and started skipping. Also noticed that the pen up/down range is fairly limited.

Wondering if there is some kind of setup or configuration that needs done? I'm using a new SE/A3 that has worked well with the default EMS-software.

ERROR

Exception: cannot find axidraw device

CORRECTION
On my side VID_PID should be '04d8:fd92'
Maybe you should compare in lowercase in the find_port() function.

I love this library, and I want to make a plot server to run on Raspbery PI.

Running the latest debian....

When I did

pip install -e .

I got a bunch of errors about libgeos. After searching for solutions
I found that doing this seemed to fix that problem.

sudo apt-get install libgeos-dev

Then when I ran

pip install -e .

I get this error, which is strange since axi is python 3 right?

RuntimeError: cairocffi does not support Python 2.x anymore. Please
use Python 3 or install an older version of cairocffi.

I came to this axi package to find out how you do your stroke font generation. I've installed axi and have tested some of the example scripts. One script that isn't working for me is pen_test.py. It seems to generate an out.png that shows pen test of a rapidograph 0.1mm. But nothing ever goes to the plotter and the script silently finishes.

(nambu) C:\Users\kanugu\code\axi\examples>python pen_test.py
(0.0, 0.0, 11.69, 2.9487756055115772)
(0.0, 0.0, 2.9487756055115777, 11.69)

the code that should plot it looks comparable to other examples I think

    d.dump('out.axi')
    d.render(bounds=axi.A3_BOUNDS).write_to_png('out.png')

Is this a package that exists somewhere? I can't seem to find it in the normal places.

Had a few challenges getting everything to install and have passed most hurdles, first Shapely wouldn't install after running your suggested 'pip install -e .' . After manually downloading 'whl' package was able to get past that message. On freshly upgraded pip and setup tools Im having issues getting past a fail to install of pyHull. Manual pip install fails as well for pyhull so I imagine its a issue with them but has anyone had kuck getting past this on windows 10? Thanks in advance
