    I was looking for a lcd screen to control my printer, and I was checking this Chinese site that had cheap knock off versions of all the popular LCD's, and I saw a touch screen that said it works with the mega2560 (http://www.amazon.com/gp/product/B0...rd_t=36701&pf_rd_p=2079475242&pf_rd_i=desktop). I checked thingiverse and saw people with mendel i3 and other printers using this screen. Is anyone here using this touch screen controller, and if yes can you please give feedback about how well it works, and how easy/hard it is to setup.

    That is meant to mount directly on the Arduino (like the RAMPS board) so I doubt it will work for you.

    I guess if you run the wires directly off of the Arduino and mount it outside and there are no conflicts with the I/O used by the RAMPS it would work.

    Do I need to do anything as far as the firmware is concerned?

    What is your experience with Banggood? Their prices are great, but how is their customer service and shipping times?

    Took me two weeks and a couple of days to get mine. I live in Tennessee. Customer service is pretty good though

    Good to hear, Amazon is getting pricier and pricier. I would love to give this website a try.

    @Johnny Yuen - I did a lot of purchases from DX.com back a long time ago. When then I found Banggood. I was starting to do a bunch of stuff with Multi-rotor aircraft. For many things their pricing is just as good as Hobbyking, or even better. Even their cheap (free) shipping gets me my order in about 2 weeks to the eastern U.S. If they have the same item in the US or UK warehouse, it's like only about $2.00 more for the item, but you will get it within a week. Sometimes that works out cheaper than their expedited shipping from China.

    They don't have a lot of stuff for 3D printing yet, but their inventory is growing. I find their pricing better than Amazon and eBay. And don't be fooled, a lot of the stuff posted on Amazon comes from the same suppliers in China.

    In addition, their points system allows repeat buyers to generate their own discount coupons, plus they are currently running their 10 anniversary sale.

    I must say for $24 versus $13 after shipping costs, it is really worth it. Ended up getting the Ramps 1.4 LCD.

    I just got my
    RAMPS1.4 12864 LCD Display Controller Kit For 3D Printer from Banggood

    For Robo R1 Plus
    I downloaded the source code from
    http://download.robo3d.com/firmware/R1/ROBO3D_LEADSCREW_V1.zipwhich unzips to Robo3DR1PlusV1

    I comment out line 505
    // #define REPRAP_DISCOUNT_SMART_CONTROLLER //robo
    And uncomment line 515, 490, 496,497
    #define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER
    #define SDSUPPORT // Enable SD Card Support in Hardware Console

    I load the latest U8Glib 1.18.1 (I tried all the version from 1.4 up)
    https://bintray.com/olikraus/u8glib/Arduino/view

    It compiles and uploads, the printer works with matter control but the display is not working. It is stuck in a state of all pixels on white or bluish.

    I added a resistor to pins 2,3 and the display brightness can be dimmed to black now but no writing on the screen at any level.
    I also does not beep when powered up.

    Has anyone gotten this display to work?

    Thanks,

    Peter

    Do you have it connected right? I know that some of the knockoffs have shipped with things as bad as the hard mounted connectors installed 180 degrees off. Try swapping the exp1 and exp2 wires. if that doesn't work, you may actually want to try turning them 180 and forcing it in against the key.

    Thanks for the input...

    I have tried swapping 1 & 2 which results in beeping and flashing but no text.

    I found I had not added
    #include <U8glib.h>
    At the top of the Configuration.h. file.. but after adding this, still no luck.

    It is a little scary to turn it upside-down... fear of putting +5 on Ground, etc...

    Well you get what you pay for... I paid $12 and 6hr of time...
    Chinese manufacturing at its prime... As you suggested I filed off the tabs and up pops my display, no resister needed, etc.

    I had seen comment to this effect but the board image and the connectors matched.. I then found a photo of another brand and the key's up facing up to the edge of the board where mine are down...

    If you have a Banggood board then you need to flip you connectors....ohyvey

    Thanks again!
