LCD Smart Controller works but no menu

[russellchan123]

I have a full discount smart controller that displays the home screen with the nozzle temperature and the axis coordinates. It even displays the Marlin logo upon startup. However when I try to scroll and click nothing happens. There is no menu. It just stays on the same screen. I have added U8glib.h to my libraries and went through the configuration.h files very thoroughly. If anyone knows a solution I would greatly appreciate it. Thanks.

[Blue-Marlin]

Please append your Configuration.h and the pins_MYBOARD.h file you used (if you edited it).

• What version of Marlin are you using?

[russellchan123]

I am using Marlin 1.1.0-RC6. My LCD code is below:

#define LANGUAGE_INCLUDE GENERATE_LANGUAGE_INCLUDE(en)
// LCD CHARACTER SET
// Choose ONE of the following charset options. This selection depends on
// your physical hardware, so it must match your character-based LCD.
//
// Note: This option is NOT applicable to graphical displays.
//
// To find out what type of display you have:
//  - Compile and upload with the language (above) set to 'test'
//  - Click the controller to view the LCD menu
//
// The LCD will display two lines from the upper half of the character set.
//
// See also https://github.com/MarlinFirmware/Marlin/wiki/LCD-Language

I also tried to enable the buzzer but it doesn't make any noise. If nothing is wrong with my code, perhaps I should try an older version of Marlin or it is a hardware problem?

[thinkyhead]

Try disabling U8GLIB_SSD1306 and see if that makes a difference.

You don't need to enable DOGLCD explicitly but it shouldn't hurt anything.

Also, use the latest RCBugFix code. We might already have fixed something affecting you.

[russellchan123]

I downloaded and uploaded the RCBugFix code and get the same thing. Neither the buzzer or the scroller works but I still get the marlin logo and the home screen. Perhaps I will try an older version of marlin

[thinkyhead]

@russellchan123 Did you also disable the U8GLIB_SSD1306 option when testing?

Could you post a photograph of your LCD controller board? (The bare controller without a case.)

I also have a REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER but haven't had any problems.

[russellchan123]

I also disabled U8GLIB_SSD1306.
Just to make sure, all I should need to do is add the marlin and u8glib to the Aurduino libraries folder. I then open up Marlin, go under Configuration.h and comment in the code I pasted above. I also just need to type in #include <U8glib.h> to reference the library right? That seems to be all the steps that I have found online and I suppose it is partially working otherwise I wouldn't get a home screen on my LCD.

[Blue-Marlin]

"ERR: MINTEMP" kills the machine immediately. No input is possible then. Ether connect a thermistor or use a fake thermistor (998 999).

[thinkyhead]

I also just need to type in #include to reference the library right?

That will be done for you automatically when you select a graphical display.

I suppose it is partially working

It's definitely getting close if you have a status screen. I wonder if there could be timing issues involved. Recently some board-specific delay code was added to ultralcd_st7920_u8glib_rrd.h. So you might try adding these settings to your Configuration.h and try different delays:

// If you want you can define your own set of delays in Configuration.h
//#define ST7920_DELAY_1 DELAY_0_NOP
//#define ST7920_DELAY_2 DELAY_0_NOP
//#define ST7920_DELAY_3 DELAY_0_NOP

You can replace DELAY_0_NOP with DELAY_1_NOP, DELAY_2_NOP, etc. See ultralcd_st7920_u8glib_rrd.h for the combinations currently used for different boards. @Blue-Marlin might know more about whether these delays will help.

[Blue-Marlin]

MINTEMP ERROR -> NO CHANCE TO GET INTO THE MENUE. Look at the picture.
Don't mess with the delays. If you see a unscrambled picture, they are ok.

[thinkyhead]

Translation: Your display is working!
If it doesn't work in situ then there could be some kind of static interference.
Check the wiring to make sure everything is tight.

[russellchan123]

Thank you so much everything works fine. I just had to plug in the thermistor. I just assumed everything would work without it. Again, thank you.

[Blue-Marlin]

Do we need an kill-screen? A error message in the baseline seems not to alerting enough.

-------------------
|ERR: MINTEMP     |
|                 |
|machine killed   |
|Please reset     |
-------------------

Looking at the terminal output seems to be completely out off fashion. :-(

[Roxy-3D]

Do we need an kill-screen? A error message in the baseline seems not to alerting enough.

I presume you mean something that takes over the entire display? That might be a good idea. Something else I would like to see is a small area of the screen that developers can take over and put up short messages.

[Blue-Marlin]

How about "the status line". Simply do it.

[msamblanet]

I just encountered this also - something as simple as changing the text to "Err: MINTEMP - Halted" might be sufficient (if it fits) - I saw the mintemp error but did not realize it halted the board. This would seem to be a common mistake for those of us taking our boards away from the printer to update firmwares and such.

[thinkyhead]

Is it worth including the last (failing) temperature value on the screen?

[Blue-Marlin]

In almost all cases for a MINTEMP error this will fail during boot - no previous value.
The kill-scren can display other kill messages, not all are temperature related.
If you really want - squeeze the temperature into the status line.

[russellchan123]

So using my LCD screen I can move the axis. However, the axis only goes one way. For example, when I go from 0 to +10mm it moves but if I try to move it back from +10 to 0mm nothing happens . Do any of you know what could be causing this issue? Perhaps it is in the code somewhere?

[lavato]

This is the same issue I raised months ago #3257.

I think people mostly experience this when they are building a new printer or testing new HW.

What would have helped me at the time is if there was a Warning message next to e.g. Board section in the Configuration.h informing users about:

• the need to connect thermistors or
• suggest to set a thermistor type to 999 so that they can test their HW without having to connect anything.

error message in the baseline seems not to alerting enough.

I also agree with above Blue-Marlin's comment that the current message to new users is not alerting enough, it wasn't to me at the time.

[Blue-Marlin]

If you'd write "I see a MINTEMP error" we'd immediately know what to do. If you tell us "Can't get into the menu" there are some dozen possible sources for the problem.

[Roxy-3D]

I also agree with above Blue-Marlin's comment that the current message to new users is not alerting enough, it wasn't to me at the time.

[thinkyhead]

if there was a Warning message next to e.g. Board section in the Configuration.h

And/or in the LCD Controllers section. This is a good (although non-obvious) use case for those dummy thermistors. Perhaps it even makes sense to set 999 as the default thermistor (only in the base configuration) instead of 1…?

If you'd write "I see a MINTEMP error" we'd immediately know what to do.

True. Well-written bug reports save us a lot of time chasing wild gooses.

[Blue-Marlin]

Perhaps it even makes sense to set 999 as the default thermistor (only in the base configuration) instead of 1…?

Sorry. No. That's not safe. If you set an target temperature the heater will heat infinite if the thermo protections are off.

[Blue-Marlin]

Let's see if the 'kill-screens' will help.

[thinkyhead]

if I try to move it back from +10 to 0mm nothing happens

This might occur if you have not homed with G28 yet, but you have Max endstops enabled, so you are only allowed to move in one direction. This would occur in an older version of Marlin by failing to enable DISABLE_MAX_ENDSTOPS. With the newest Marlin it can occur due to misconfiguration of endstops.

Can we close this issue ?

[russellchan123]

Yes this issue is all solved.
