I was recently reminded it would be nice see a write up of my experience of building a Polargraph that is controlled via a Ardunio Uno.

The kit from polargraph.co.uk is wonderful, but for a few reasons I decided to skip the kit and do the DIY thing:
    1) I can print my own parts
    2) I already had an Uno laying around
    3) I'm generally a cheapskate and I decided I could source less expensive parts

Parts list:
    Arduino Uno
    motor shield
    2x NEMA 17 Stepper motors
    one (1) 9g servo
    fishing line (had this on hand - I figure anything over 10lb test would work)
    wood board for printing surface (MDF recommended something at least 2'x2' should work fine for 8.5x11 paper prints)
    sharpie pen

3D printed parts:

Thanks for adding this Case! I need to find time to try one of these.

Yes, thanks Case!

I ordered my parts today. I think I've got just enough MDF left from the Lyman parts for the backboard.

The parts are here. I'm working through getting the software installed (Uno and PC) and working.

I won't be able to print my parts until I get the lab 3D printer finished but let me know when you get a chance to upload your motor mounts to thingiverse. They look real workable and I'd like to use them.

I edited the original post: added the Thingiverse link to the motor mounts!
