RepRapDiscount Smart Controller
Release status: working
Run your RAMPS without a computer just with a SD card!
Based on bkubicek idea, we realized this smart controller.
This Smart Controller contains a SD-Card reader, a rotary encoder and a 20 Character x 4 Line LCD display. You can easy connect it to your Ramps board using the "smart adapter" included.
After connecting this panel to your Ramps you don't need your pc any more, the Smart Controller supplies power for your SD card. Further more all actions like calibration, axes movements can be done by just using the rotary encoder on the Smart Controller. Print your 3D designs without PC, just with a g-code design stored on the SD card.

As firmware we used Marlins' sources, to update the firmware in the future you just need an Arduino board, so you are good to go ;)

There are two identical connectors on the display board, which take ribbon cables to connect to RAMPS. If you switch them you'll just get beeping to let you know it's wrong.
The connector nearest the wider end of the L-shaped "smart adaptor" is #2; the other is #1. Looking at the bottom face of the display card, with the ribbon cables going away from you (so the encoder, buzzer, and reset switch are to your right), the left socket is #1, and the right socket is #2.
- Change line 1532 to
#define REPRAP_DISCOUNT_SMART_CONTROLLER(just remove the // at the beginning)
- Change line 1429 to
#define SDSUPPORT(just remove the // at the beginning)
Upload the firmware, power off the Arduino, connect the panel, reapply power, and everything should work.
On the back of the panel in the top right corner is a tiny trimpot labelled "Contr". This is a fragile part, so be very gentle when turning it. The ideal tool is a plastic "TV alignment tool".
Settings for RAMPS1.4 in "Configuration.h" search for "REPRAP_DISCOUNT_SMART_CONTROLLER" and activate the define (remove the leading "//")
Marlin V1 RC2 (old)
Settings for RAMPS1.4 in "Configuration.h" search for "ULTIPANEL" and activate the define (remove the leading "//")
#define NEWPANEL //enable this if you have a click-encoder panel
Also change the value on
define MOTHERBOARD to 33
in "pins.h" go to section for RAMPS configuration (search for
MOTHERBOARD == 33)
