GcodeCNCDemo update May, 2015

I squeezed in some time tonight at the Vancouver Hack Space to fix GcodeCNCDemo.

All the demos in the github repository have been updated to support G02 and G03 arcs in the XY plane.

All the demos now also support checksums. You can send line numbers and a checksum bit between the ; and the \n to make sure your arduino correctly receives your message.

All of the demos will only work if your arduino is sending the newline (\n). You can turn on “send newline” from a dropdown in your arduino serial window. GcodeSender, a sister project, should already send the newline.

I’m sorry it’s taken so long, I’m working really hard to be ready for the Bay Area Maker Fair. In my vision, a person at the fair can see the Makelangelo, place an order at our booth, and get a tracking number in their email before they leave the building. We ordered parts that aren’t good enough and I’m working hard to replace them in time. Everything else is ready! We could ship the kits a week later, too, but that’s… that’s not the way I dream it should be.
