@stevec – In order to help me get in the right place to start (I agree the file structure makes digging around a pain), where did you make the change to display “Mostly Printed CNC OK”? I am using a knockoff of the sainsmart 2004 display things will be a little different.

@karltinsly – I will try that today to eliminate the error. I have an old thermocouple from a burnt up hot end from my printrbot that I am going to hook up in place of the resister to see if I can get a temp. If I can I will use this to monitor the temp in my ramps enclosure. Also did you have to shorten the name of the printer when you tried to upload? I received length errors and they went away when I change the name from Mostly Printed CNC to MPCNC.
