Just thought I'd post this up. All five axes are working well but there are still some issues, mostly sending too much IO. The pins used match up with the DB 25 pins on the MK5 but there is no support for the limit switches available on that board yet (easy). This was done with a Mega but there are enough pins on an Uno.
