How to configure Marlin to use a 12864 graphic display ?

[ekh 3]

I have designed a product with 13 pcs 3D printed parts taking 60 hours to print.

Several of the parts are not economically feasible for me cast in plastic, as the molds will be much too expensive.

As I want to "mass produce" the product I need many printers in our newly started company.

So I bought 3 pcs of this as a start:

I have looked into config.h but there are so many options that I gave up after an hour where the best attempt led to a compile error.

I have installed the U8glib library in the Arduino IDE 1.6.5.

Hopefully one of you have solved this already. I will be very thankful for an advice that makes it compile and the graphic display to function.

That will enable me to produce the printers I need. I have no intention of selling printers.

Instead I will share the design here, if I get success in making a good printer optimised for my parts.
