When it comes to the motherboard selection, I found the Ultimaker Shield 1.5... was an exact match to the items in the Marlin firmware that came with it. For my printer, the display was the ...reprap discount...... or something like that. If you have any problems, I'll gladly send you my config.h. Things are not 100% yet, but the steppers all seem to be OK, and there were several changes that had to be made.
