I new to this whole Arduino thing, but I'm trying to build a 3D printer with the rumba board. I bought a 3.5 TFT LCD touch screen with uno r3 (ILI9488) and I have no clue how to hook it up to my rumba, no pins are labeled and I can't seem to find any information that I can understand. ANY help would be appreciated.
PS. I have installed Arduino 1.8.5 and sent Merlin 1.0.1 to my board, the furthest I've gotten is plugging in the USB and jumpering the two USB pins, I also have the latest drivers.
Are you sure you don't mean Marlin rather than "Merlin"?

If that's all the information you can provide then probably you'd be better off posting to a 3D printer forum. We know lots about Arduino, programming, and electronics here but I haven't seen much in the way of 3D printer experts. So we don't do a good job of answering 3D printer specific questions (rather than general Arduino questions that just happen to be related to 3D printers). I usually try to help but I've never even used one.

I wonder if that should be RAMPS and MARLIN?
The RepRap website and Forum is a great place for 3D printing information.
...R
The RUMBA board is basically RAMPS + Mega together on one board.
Having said that, I can't find much info on using it with a TFT screen. Most setups seem to use a 16x2 or 20x4 alphanumeric LCD.
Sorry, yes I did mean Marlin, i was up late lol, and i can handle the 3D printing portion, just need to figure out how i would go about hooking this TFT LCD touch and how to change the pins for it inside of Marlin.

It says that my LCD is capable with Arduino Uno, so in theory it should work with Rumba correct? it runs a Atmega 2560
That does not mean that it will work in conjunction with Marlin.
A touchscreen is a complex device that consumes a lot of CPU cycles. Marlin (and 3 D printing in general) requires a lot of CPU cycles and very precise timing. An Atmega 2560 may not be able to cope with both.
Marlin is a very complex program and you need to get advice from people who are familiar with Marlin and how it can be configured. People on the RepRap Forum are much more likely to know about that.
This Arduino Forum is mainly for helping people write their own Arduino programs.
