Reprap discount LCD + RAMBO works in Repetier but not Marlin

[CaptainChemist]

I have RAMBO + reprap discount LCD and I am getting whiteboxes on my LCD display. I set and uncommented:

define MOTHERBOARD 301

define REPRAP_DISCOUNT_SMART_CONTROLLER

When I upload this version of the repetier firmware the screen works great so I know it isn't a hardware issue: https://github.com/polygonhell/Repetier-Firmware

Unfortunately, going between repetier and marlin is a little out of my pay grade. Thanks to anyone who can figure this out!

I have a similar issue, using a RAMBo 1.0 and RepRapDiscount LCD. Works fine in Repetier, but not in Marlin.

I know this issue is a bit old, but here goes my answer : You probably need to install the arduino addons for RAMBo and select RAMBo as the board type, otherwise the LCD won't work. Have a look at the user manual on pages 13 and then page 42. User manual is here : http://reprapelectro.com/?attachment_id=252

This one is created about a year ago and there have been a lot of changes, please download the latest copy of marlin and see if the problem is still there. Also you the latest arduino IDE to flash the marlin firmware. If you board files etc only work under old ide upgrade those first so they work under latest IDE.

If you create board files for hardware that are not in the https://github.com/ErikZalm/Marlin/tree/Marlin_v1/ArduinoAddons then please fork marlin and add the files and then create a pull request so that we can get the hardware supported. This will also give an idea what hardware people are using.
