Newbie setup of the 12864 LCD on prusa i3

Can anyone guide me as to how to hook up the 12864 LCD to my folger tech prusa i3?

Im using this setup now but with a pc Ramps 1.4 + A4988 + Mega2560 R3

Thanks

There are a few 12864 LCD's out there, some are dedicated to RAMPS and come with the "L" shaped ribbon cable connector, others aren't. Some of them won't even run on 5V RAMPS, because they need 3.3V.

Yeah this one is the L shapped ribbon cable

My folger tech printer came with marlin and i despite following instructions i wasnt able to get the screen to work.

When i downloaded the latest marlin and followed instructions on modifying the code for sd support and the #define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER the screen worked but i nearly busted the printer . It would try to home in the x and y axies and ram into the end stops and not stop.

When i tried running the printer with a computer and repetier and no lcd panel i lost my heated bed function.

I ended up loading the old marlin firmware and recovered the heat bed function on repetier using a pc.

Is there a guide on properly configuring this lcd so the printer works properly?

You've already found the way to run the LCD, but you missed the opportunity to configure all the other bits&pieces too
