I had some time to install a Olimex A20 with the 7 inch touch screen on my TAZ. The printer is now wireless connected to the internet and my Mac. No need to let the Mac running while printing for hours.
I first installed linux, but the board kills linux on the SD card every time it is not shut down properly. Now I’m running Android and GcodePrintr. I can now send my gecode over wifi to the printer. And i can now order Pizza with my TAZ.
