First, you need to get Arduino up and running with a PrintrBoard. They want you to use a very very old version of Arduino. The reason is the PrintrBoard additions do not work with every version of Arduino.
This version is very old, but it does work. Hopefully, it still works with the newer versions of Marlin.

If it doesn't we can (with work) get you going on a newer version of Arduino. (I have a PrintrBoard on one of my printers and have it working with Arduino v 1.06 )
The firmware appears to be fully published at this link: [blog.solidoodle.com] It is a fairly old version of the firmware. You will want to update to the newer versions of Marlin. Mostly, you will abandon all of the source except your configuration information. That is Configuration.h and Configuration_adv.h. Because you are using a PrintRBoard, you may want to double check the Pins.h file to make sure there are not any changes that need to be crossed over. What you want to do is take all of your settings from those files and make the new files have the same values. You can't really just replace the new files with the old ones because a lot of extra features have shown up and you need to go through line by line and cross the changes over in a rational way.
