I'm super happy with my purchase. These boards are exactly what my 3D printer needed to be able to express itself.
Before ordering the boards, I had read through all the documentation so I knew what I was getting into and even received several (patient) responses from the seller to questions about the boards/wiring/etc. The documentation is everything you'd want to see in instructions. It's got lots of pictures, diagrams, helpful hints, links to related resources and code, and a fair bit of humor and whimsy. The boards are based on the Arduino platform, so it's possible to reprogram and extend them to do even more.
Thanks for putting together and supporting such a great product!!
My Marshmallow board arrived quickly and was extremely well packaged in an anti-static bag and then embedded in a bit of foam in an envelope.
Installing a coin cell was simple and secure and my little Noodleling booted up immediately to keep me company through the process of 3d printing its body and assembling it. Now it keeps me company during the day with its encouraging beeps and blinks.
