We all know it's open source. Wish we could see it released before committing to back the printer. Here is an explanation from one of Peachy Printers KS admins.

We have not yet released the software because we want to get it working better and have a strong foundation before we open it up to the open source community.
When it is available you will be able to download at the download section of the Peachy Printer website.
Its blank now, but here is the link it will be available at:http://www.peachyprinter.com/#!download/cfvg-Kaleb
Do you guys think we will see the software released prior to close of the KS campaign?
