RepRapDiscount Full Graphic Smart Controller not working

I plugged in a Graphic Smart Controller, and the screen lights up, but stays blank. The click encoder and speaker work (it beeps when I click the encoder), and the kill button stops the printer as expected. Also, the SD slot lists files correctly in Repetier host. I've tried:

• Installing UG8LIB
• Uncommenting #define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER
• #define MOTHERBOARD BOARD_RAMPS_13_EFB and #define MOTHERBOARD 33

Here is my Configuration.h (Marlin rc2. Note that the LCD doesn't work in Marlin release V1 either):

 * The issue: If a thermistor falls out or a temperature sensor fails,
 * Marlin can no longer sense the actual temperature. Since a disconnected
 * thermistor reads as a low temperature, the firmware will keep the heater on.
 *
 * The solution: Once the temperature reaches the target, start observing.
 * If the temperature stays too far below the target (hysteresis) for too long,
 * the firmware will halt as a safety precaution.

I just bought one of these and it had a couple broken traces. I've also heard of bad solder joints and ribbon cables with these. The contrast knob on mine is kind of touchy as well. I would get a RAMPS pinout and schematic for the LCD and check continuity on everything. Once I got it going, it's great. I messed with the firmware for 2 days before I noticed the traces.

Edited 1 time(s). Last edit at 12/06/2015 04:16AM by kerkove.

Also the two ribbon cables should go in the right place, check google images to find out.


-Olaf

If your encoder is working, the ribbon cables are connected correctly. (There were some made with the connectors labeled incorrectly on the silkscreen.)

Forgot to mention, I also switched the wires, but it didn't work. I'll try the pins with a continuity tester as @kerkove suggests, and post the results here.

Any luck testing the continuity?

Haven't gotten a chance yet- got some deadlines this week so the printer was put on the backburner. I'll try Friday or over the weekend.

Yeah, I think there's an electrical problem. There were a few places where the continuity didn't match the diagram, and I can't access many the traces because my lcd is soldered on.

Check the following:

RAMPS D16 to LCDRS on LCD (pin 4)
RAMPS D17 to RW on LCD (pin 5)
RAMPS D23 to E on LCD (pin 6)

Check for 5V between pins 1 & 2 on LCD
Check from A+ on LCD (pin 19) to GND while adjusting contrast potentiometer. Verify range from ~0 - 5V.

EDIT: Oops.

Edited 3 time(s). Last edit at 12/19/2015 06:45PM by kerkove.

D16 goes to pin 4
D23 goes to pin 6
D17 goes to pin 5

I tried reversing the two in firmware but it still didn't display anything. Should I try with an older version of arduino (I'm currently on 1.6.7)?

1-2 has 5V
19 goes from 0V to about 3.3V

Edit: Neither 1.6.0 nor 1.0.6 helps either. I updated to RC3 but that still didn't help.

I tested all the other pins, and they are how they're supposed to be.
The arduino is fine, so now I'm testing the ramps board.

Ok, I'm beat.
I tested continuity on all pins that connect to GLCD1 (on the RAMPS and on the smart controller) (they are as they are supposed to be. I double checked and 17 is supposed to go to pin 5.)
All the outputs on the arduino work.
Nothing shorts to ground or 5v.
I tested practically every possible change in firmware.

Edited 4 time(s). Last edit at 12/19/2015 06:53PM by dmelcer9.

Yeah that's weird. All I had to do with Marlin RC3 is uncomment the controller in configuration.h.

I think I may have simply gotten a lemon LCD *shrug*

How are you powering the 5V for your RAMPS? Also, when you were checking the lcd you checked it on the front, under the panel itself?

Edited 1 time(s). Last edit at 12/19/2015 09:10PM by kerkove.

The ramps is plugged into the computer by USB, and using the 5A/11A ports on the ramps board. It doesn't work no matter the configuration of the power.

SPAAAAAAAAAAAAAM!

EDIT: Impressive, but still SPAAAAAAAAAAAM!

I have exactly, and I mean *EXACTLY* the same issues. I have gone through and checked all continuity, voltage is good, current good. But.... alas, there is nothing on the display other than the pretty blue light. Doesn't matter what I have tried in the firmware, all ever does is is light up, allow SD and the piezo to chirp when you press the rotary switch.

I have noticed that the pots on the front (its a red PCB, RRD FGSC, chinese clone) does sweet f/a. Nothing. Zip. Nada. I have even tried the 470R resister on the back like suggested in others situations. But still, to no avail. So maybe it is working, but the contrast cannot be changed, so I cannot see it? I don't know. Maybe. Not being able to change the contrast isn't helping. There is no other pot on the device, not under the screen itself, I've had a look. All traces seem fine. No solder overflow onto the traces or other contact points. Just the blank stare from the unit itself. I know the rest of the machine is good. I've had successful prints out of the unit via laptop, but cannot get the good for nothing FGSC to play ball!

I too am at a complete loss as to what exactly is going on.

Looks almost the same as mine, except your pins are labeled and the Website URL is a bit different. Probably from the same Chinese knockoff manufacturer with ...questionable QC.

One minor step in the right direction. I followed the instructions at the bottom of this page, [www.smw3d.com] - specifically the part about the pot (already had the through pin it speaks about in there). So I removed the 470R I had put up on those holes, removed the original POT, and replaced it. Now I can at least change the contrast... On my blank display... Which, is still, you guessed it. Blank. Although now I can change the contrast of that blankness.

*sigh*

I should mention I have tried this in V1.1 RC3, and V1.0.x

V1.0.x does make the piezo louder... but, that is all.

Got it working. Bloody thing. Turns out the FGSC is GTG after all! However the supplied cables are poop. Somehow I could get good continuity (tested with a recently calibrated Fluke 189) through them but I suspect that they had a break or a loose pin on the connector or something like that. I replaced them with some I made myself and bingo. Lights up and has data displayed.

I got continuity on both cables. I'll see how using a different cable works though. My contrast potentiometer goes from 0 to 2.5Kohm. Is that normal for the LCD?

I had exactly same blank screen when I started, but it was the lib's weren't added to the code at the beginning and defined at the end, UG8LIB & the dogLCD the ultra too not sure if they where all needed but it works now, maybe your trying to fix problems that aren't there? maybe breaking things in the process?
not that I have a clue about the electronics your altering.

dmelcer9

I had a quick look at your config h file and the only differences between yours and mine is

These parts

// The following define selects which electronics board you have.
// Please choose the name from boards.h that matches your setup
#ifndef MOTHERBOARD
#define MOTHERBOARD BOARD_RAMPS_13_EFB
#endif

Are you sure you have a 1.3 ramps board and not a 1.4

and

// #define DISPLAY_CHARSET_HD44780_JAPAN // this is the most common hardware
#define DISPLAY_CHARSET_HD44780_WESTERN
//#define DISPLAY_CHARSET_HD44780_CYRILLIC

I have the JAPAN charset defined where you have the Western

Might be worth changing these parts and giving it a go since you have obviously tried almost everything else

If need be i can post my h file

Many thanks

Dave

dmelcer9,

Any progress? I know its bloody agitating when one solution for one, doesn't work for you, despite the similar symptoms - did you get a replacement?

Any luck with different cables? I used a break out cable/jumper cable solution to pinpoint the issue for me.

But maybe it is a bad unit after all...?

On some of these there is a pot on the back of the screen itself look Inbetween the screen and board. It's almost impossible to get to tweezers or small needle nose pliers, some have added a resistor. There is another thread on here with more details

My two PCB's were touching and shorting out sometimes. Gently pried them apart and inserted some kapton tape in between. Any non conductive sheet (OH film) should work.
This eliminated my issues with the RDFGSC.

Good luck!
