-I completely changed the underlying communication library. In 1.0 the used library was the QextSerialPort library but because of some problems I had with it I was only able to get it working when the communication was polling-based. That was not really good because there was a high and unnecessary CPU usage. Now the communication works event-based and is completely implemented with the Qt integrated SerialPort library.
Load the first layer and start the print. after that you will get a dialog asking you to change the pen and press OK. Then it automatically loads the next layer and starts printing. After the last layer it will ask you whether you want to restart and print the next egg.
-A really nice feature is the persistence of the loaded file and the connected port. So if you connect your bot to the computer and start the program, it will remember that it was connected to this port the last time and automatically connects to it. It will also loads the file that was loaded the last time at start up.
So these were the most important changes I´ve made to it. I hope you ´ll have fun with it ;)
