I noticed in the Cbot thread you mentioned you had an Azteeg x5 but you had some questionable experiences with it. DId you have the v1.1?
On the C-Bot build, you said you are using a Smoothieboard. I was wondering if you are also using the GLCD shield? I bought one with mine with the intention of porting over the display I am building for the RAMPS board. However, it did not come with any instructions or information and I can't seem to find anything online about it. Really starting to think I wasted my money on this. :(
I actually have an Azteeg X5 but do not use an LCD. There is a thread for smoothie board's GLCD connections over on Google groups delta printers section.
