LCD Full smart graphic controller - not working after some time

N37 · October 2016

Hello, i have got ramps 1.4 , 1 extruder heated bed and grapohic controller from reprap discount, the one with sd card reader.

I have flashed arduino with firmware configurated online,no sd support support for full graphic controller enabled.

And i have noticed strange thing. Sometimes everything works fine, and controler lcd shows things fine, sometimes when i do put sdcard works fine, but when i start print from sd, after reboot the lcd is showing total mess.

Printer works but lcd is not showing content correctly,

SOmetimes flashiung marlin and flashing back repetier helps, and after a few reboots problem occures again.

DOes anyone know about issu with full graphic smart controller ?

how to fix it ?

Sounds like signals to lcd get corrupted. Complete unpowering and restarting should fix it, once it happens. No uploading of different firmwares needed. Typical factors for getting corrupt data is crosstalk if cables touch high current wires like bed/motor or long cables. Bad contacts would be a last reason. As it normally works you already know the firmware is sending data correctly. Firmware continues running as it only sends and does not query data from display.

N37 · October 2016

True, but wiring is fine as the board is sitting on desk aside of the prinet as for testing purposes.

I've noticed that changing arduino board to second one , and connecting the "old" one makes the LCD working again.

Today i've had all day working without problems till the momment when i have disconnected the extruder stepper and connected it for testing to the X axis stepper, and "bum" LCD corrupted.

I do always switch off all power when changing things on ramps.

And ones again reflashing marlin and flashing back repetier fixes the issue,

Disconnectin any of the steppers and connecting it back makes the LCD corrupted again.

=======

I'll try to trace the source, i'll put EMP shielding on all wires using aluminium tape and capton tape on aluminium to prevent shorts or something and i'll post the results, if the source of the problem is interference i'll post it. Tommorow i'll get the arduino board with ARM, to check if this is connected with processing power.

I have got one question relating to my config.

I cannot run the stepper on extruder 0 or extruder 1 on my ramps 1.4,

Also my cooler is not working when connected to D9 on RAMPS 1.4

N37 · October 2016

Ok, so i have shielded the connection cables from RAMPS to LCD with aluminium foil and than with capton tape.

And problem was solved solved.

LCD starded showing fine image.

But than i wanted to test scenario with disconnecting connector of the stepper. So i have disconnected the stepper and the problem is back . Regardles of everything LCD is corruped again.

I'm out of my mind.

N37 · October 2016

I've tested same scenario with marlin firmware, and there is no glitch with LCD, using RC7 and swapping pins and so on, eben on clean not shilded cables without carring about interference and other things you mensioned, on the same hardware without modifications and there is no problem with LCD on ramps plus arduino duo r3 clone.

Problem is showing only on repetoer o.92 and it stil occures after that on marlin. The solution is to disconnect everything and live it for some time and than LCD works until disconnecting or swapping stepper motor.

And than even on marlin the problem is the same.

But when using only marlin there is no problem.

Maby it is a problem with software, or library that is used for smart controller ?

No idea here.

But second thing i want to share, if i use 4 line alphanumeric LCD and separate keypad on the same version of repetier (I do own Renkforce RF 2000) there is no problem with LCD and connecting disconnecting pins and so on.

So my suggestion is that we should look in to code/bug or computing memory amounts on arduino duo r3 ?

Tommorow (monday) i'm getting arduino clone based on

ATSAM3X8E Cortex-M3 MCU

And new ramps shield and cables for smart controller, with better quality than the ones i have.

I'll see if the problem is there too. and i'll post the testing results.

Thanx for your feedback.

Any other ideas to solve the problem ?

With D9 you have to watch out. By default second extruder and fan use same pin, so you may only use one of them.

What makes no sense is connecting/disconnecting steppers having an influence. As I understand you mean simply physical removing it. I mean you use different pins for display.

Marlin and Repetier use same u8glib for communication. The only thing I modified is setting pins which I made faster by using the WRITE macro, but it still gets same commands.

N37 · October 2016

I've noticed that, that's why i'm so confused.

I've been speaking about that problem with my programist, a guy is more .net / mobile than embaded, but he pointed me to not enough memory /processing power as the source of the problem.

I can eliminate the hardware/connection shielding problems in 100% , because with marlin it works, i've tested the hardware over the night with extensive printing etc. problem only shows up in repetier, right now 0.92 configured as in my firs post.

For testing I have doisconnected all external wires, clean board with stepper drivers DRV8825 and phisicaly reconnecting stepper motor connector from the ramps board, let's say from E0 to X gets those LCD problems to show.

I have got 5 ramps shields from 2 vendors.

4 arduino MEGA 2560 R3 from 3 different vendors.

2 RepRapDiscount Full Graphic Smart Controller (red PCB) so genuine.

Mixing the hardware in many ways has got same results, so it it near to impossible that problems are hardware related.

and today i have recieved RobotDyn DUE with Arm M3 ATSAM3X8EA AU.

The ARM board is clone of Arduino DUE but in very fine condition, well made .

I cannot test it yet because i cannot program it, some problems with arduino IDE and windows 10 clone assosiated,

When I make it working we will see if the problem with LCD is related to small hardware resources on MEGA 2560.

Because on ARM board LCD should work fine if that's the source of problem, i'll post results

someone have told me that Arduino team is working on "eliminating" clones from supported devices, and in some way cince 1.6.6 they implemented some kind of mechanism that makes hard to get not "genuine" board to work, i do not know if that's true, but i cannot program the board, I'll try to burn the bootloader ones again by my self as fast as i'll find propper programer on my desk

N37 · October 2016

One last suggestion,

As you may see on photo of LCD https://drive.google.com/open?id=0B4X4QYpSs7s4WlhFZ0FDQkVvS28

Those artefacts on GUI are parts of bootlogo and texts with website url and name that should be shown on startup before actual GUI is shown.

It looks like some parts of memory for graphics is nod cleaned before showing the GUI.

It might be a problem with that, the lcd is showing parialy home screen and menu, because between those artefacts i do see elemts of home screen and elements of menu when i access it with rotary encoder. I can even navigate and triger proper functions. Just those "artefacts" are not properly refreshed parts of LCD. I thought that might be a damadged LCD controller or so, but "map" / places where those artefacts are is not always the same, and it is really random.

So maby there is a problem with pointing to a proper range of memory to be erased refreshed when showing gui ?

I'm not sure but a friend programmer was pointing to that conclusion also.

Maby it will help with debugging.

Still fighting with that ARM based board to check the firmware there where we have more resources for prosessing power.

I'll post if i'll make any progress with that DUE clone.

N37 · October 2016

Ok, i know how to "controll" the issue.

LCD works everything is fine.

menu works, i can change language... (here i have found bug, bat that's not important now. when you change language the menu is changing to choosen language, but status info on bottom is still in the language you had before, the message is changin to actualy set language only afret reboot, but it is minor problem)

And now magic, we are rebooting the board by disconnecting the usb cable from host computer, no other connections to the board except of thermistors from extruder and bed.

and there is the glich on bootscreen and then on home screen (in my opinion time to boot up the board seems to be quite long.

And now repitable controlable solution to get it back to work.

Disconecting powersources, leaving for a few hours disconnected from everything does not work, the problem is stil after powering up the board.

So the only solution, and 100% working time after time is just to disconnect the LCD header from RAMPS while the device is up and running (i know that we should not connect/disconnect peripherials when device is powered, but i was a bit in need of solution so i have tested this scenario.

Disconnecting the Header is not the only way.you can just disconnect the cables from the lcd side or the header side, and it works . In short words LCD memory is not properly cleaned at the start.

Looks like closing cleaning procedure before it do what it supposed to at boot time. and the memory is messed up with garbage...

Sorry i'm more mobile dev than embaded so i'm just gessing.

Probably some kind of delay after refresh . so maby bug is in u8glib ?

Or maby some Call funtion is not working ?.

Now Im connectin the header back (the board is still connected to power over usb, no reseting needed, no reflashing firmware whatsoever.

and...

The LCD is showing again everything as it should, you can access the menu, navigate everything works fine...

Till nex reboot.

After reboot you get mess on LCD and you can again disconnect header and connect it again and problem is solved.

Tested on 4 Arduino Mega 2560 R3, two display modules and i can repeat that with 100%.

So what disconnecting LCD header while the board is still powered on and connecting back changes that the LCD is back in good shape ?

Maby some refreshing commands are not implemented correctly in the firmware ?

And here after reflashing repetier with older version of u8glib for testing.

The left side of home is on right, and right on left, with artefacts as always, and as before disconnecting lcd and connecting back withowt powering off arduino board helps.

I'm using

Arduino IDE 1.6.12

windows pro 10.

Arduino MEGA 2560 R3

RAMPS 1.4

RepRap Discount Full Graphic Smart Controller

DRV8825 stepper drivers

and firmware from online configurator, package with firmware here on my server for download if needed.

I hope that it helped and we will get a solution for this, for now i'm stopping wit post because we have very long posts without solution. I'm waiting for suggestions.

There is no clear display memory. The output is rendered on the arduino and then the complete bitmap is send to display. Since we do not have enough memory this is done in 8 chunks. So every loop we compute 8 pixel lines and send them with software SPI to display. The display memorizes the pixel send until they get overwritten.

As you see parts of start up logo, it is quite clear that following updates do not update all pixels. Assuming firmware does always create correct image (replugging corrects it so it is still working), the problem must be that spi communication breaks. So have here chip select, mosi pin and clock pin. If one of them gets wrong or bad timing the image gets not transferred correctly. But then parts you can see are at right positions. That might be because there need to be 3 byte transfer per 8 bit, so I guess every byte contains position for the 3rd byte.

But why does connecting a unpowered motor change how spi is working? And why for you and not my printers. No other user complains. Have you tried a minimal firmware setup - mainly default plus display and nothing else?

At startup you should have at least 1kb free ram. Log shows free ram. Only with deltas ram is a real issue.

Forget abot plugging and uplugging motors, as you see on photos, there are no connections to them on pictures and problem still presists. even on "naked" ramps , i have just connected thermistrors to see if LCD shows dynamic data in real time (temperature changes)

Assuming that plugging and unplugging motors do affect LCD was wrong assumption in order that i have to switch on and off power supply to unplug motors (if I can I always change wiring on unpowered device, that is a good habbit when working with electricity

)

So i Assumed that unpluging/switchin motors is a cause of the LCD mess, and when i decided to eliminate all unnecesary connections to trace the source.

( I know exactly how annoing is a BUG notification from a user who is saing "hey i've got a bug in my phone, than I ask what kind, and she is saing, no idea it is not working, when I turn it on and off it is working so what is a problem and how do you fix it Mate ? " )

So step by step i have figured out that problem presists on reboots. but not normal reboots, but on repowering Arduino.

Because when i reboot the firmware using "STOP" button on That controller it still works fine.

I do see logo and the GUI is loading properly without any problems.

That messed up image on LCD only appears when rebooting device by turning off the power, doesnt matter if it is switching off the power supply on printer, or by unplugging USB cable from laptop.

As I said when I press STOP button on smart controler firmware is reloading and LCD is fine.

And it must be Repetier related, because on the same hardware i was using marlin from RC branch and from bugfix branch and it works no mather what I do wit powercycles, reseting rebooting.

But if the problem with LCD is on repetier it can "stay" even if i will flash marlin to the board.

But if i disconnect LCD and connect it back it is fine, and it stays fine while rebooting and disconnecting power from board.

So Repetier is a source of that Glitch for sure.

I know a bit about that stuff as i'm 36 year old man who works in that kind of envinromant (software houses, hardware design, and bug tracing day by day) it's pitty that i'm starting my journey in embadded world , because i would like to help with the solution by my self, but i do not have much expierience yet and day by day i'm learning.

Sorry for my english do better speak than write.

So what solution do you suggest ?

I do see a post here:

https://forum.repetier.com/discussion/657/problems-with-smart-lcd-repetier-firmware

and there is a mension about refreshing the lcd content, where can i experiment wit that and how to enable it in firmware (i do not trust much "online cinfigurators" sorry it is a old habbit if i do see the code i can understand it if i only witch menu options than it is harder to imagine the whole dependencies. So point to the file to mess with would be good point to start.

N37 · November 2016

The problem is important for me, because I do plan to start production of printers before end of this year. Right nowe we have already prototypes ready from lasercutting i'm putting them tougether from pieces and adjusting things before final production.

We are thinking about working with you guys and offering addons with OEM repetier server licences, and so on...

The minimal setup is assuming using the "big LCD"

with repetier firmware, as I'm happy with that firmware on my RF2000 (not in 100% because pause print is not working for example) but i do know that it is already fixed)

Normaly i would choose firmware that "just works" and this is marlin as testing shows, especialy with that freaking Full graphic smart controler, i have even thought about using some OLED wit 1306 controller as it could be easyly supported.

I just like the repetier functions and I would like to stick to one line of host/server/firmware just to make things simple for future.

We are working on the printer based on ARM controler also, so we could help with testing in future.

For now we just need to have working repetier version without LCD problems.

I can Use 20x4 LCD , but i do not want. I want this big blue LCD that I have already

Repetier · November 2016

Ok, so to summerize if you unpower it fails. If you then unplug lcd and reconnect it works, right?

So why would it work if we skip any initialization and does not work with?

I had a closer look at u8g lib and compared it with Marlin. Marlin has rewritten the driver to get faster communication while I have improved the send byte function. Marlin did even distinguish different boards, also I do not understand why the same display needs different timings for different boards. It also looks like initialization differs a bit with Marlin essentially giving it a bit more time.

Could you test the marlin timings? Go in u8glib_ex.h line 2488 which looks like this:

static const uint8_t u8g_dev_st7920_128x64_init_seq[] PROGMEM = {

U8G_ESC_CS(0), /* disable chip */

U8G_ESC_ADR(0), /* instruction mode */

U8G_ESC_RST(15), /* do reset low pulse with (15*16)+2 milliseconds (=maximum delay)*/

U8G_ESC_DLY(100), /* 8 Dez 2012: additional delay 100 ms because of reset*/

U8G_ESC_CS(1), /* enable chip */

U8G_ESC_DLY(50), /* delay 50 ms */

0x038, /* 8 Bit interface (DL=1), basic instruction set (RE=0) */

0x00c, /* display on, cursor & blink off; 0x08: all off */

0x006, /* Entry mode: Cursor move to right ,DDRAM address counter (AC) plus 1, no shift */

0x002, /* disable scroll, enable CGRAM adress */

0x001, /* clear RAM, needs 1.6 ms */

U8G_ESC_DLY(100), /* delay 100 ms */

U8G_ESC_CS(0), /* disable chip */

U8G_ESC_END /* end of sequence */

};

and set the first

U8G_ESC_DLY(100),

to

U8G_ESC_DLY(120),

That would be the timing marlin is using.

Are you using long wires so that it takes a bit longer?

N37 · November 2016

I've tested range from 100 to 150 and only difference is that when I flashed the firmware at first time with 120 after reboot (reboot after flashing, not unpluging the powersource) LCD was fine, but it might be similar to usung STOP button.

But nothing changed, the problem presists in the same shape.

I have got connection wires (RAMPS <==>LCD) in two variants, i've tested on 15 cm and 30 cm, in both cases the same results, bug is still there.

N37 · November 2016

One more thing.

When I do not unplug LCD connector from RAMPS and flash the Marlin firmware on the repetier when the problem is active the LCD has got same problem with marlin on board.

Problem ends with power reboot, and is not comming back (still marlin onboard)

So:

Flashing Repetier unblugging powerand rebooting = Problems with image on LCD

Flashing then Marlin without disconecting power or disconecting LCD header before to fix LCD = Problems with LCD even with marlin flashed.

Then rebooting board by disconnecting power (in my case USB) (marlin onboard) = No problem with LCD and MArlin works evry boot/ reboot/ power off/power on.

SO now flashing back repetier, and when the firmware is flashed and rebooted the LCD works fine, no problems with repetier GUI .

Now powering the board off by disconecting USB, and powering back by connecting USB and LCD has got old issue.

And that can be done endless times. So it is repetable in 100%.

It looks like the problem is only when starting the board after disconecting it from powersource.

Simple reloading firmware eg. when you use STOP button on controller or when you are flashing firmware from marlin to repetier gives fine working LCD without issue.

Also, when repetier is actual firmware, and after reboot when the wroblem is active, when i disconnect LCD cable as described before and when it starts working fine, and then when I flash the repetier ones again and just firmware reloads/reboots after flashing the LCD is fine too.

JUst disconecting/connectoing powersource makes the problem to show again.

So only problem presists when unpowering board and powering back.

What alse can I check for You ?

N37 · November 2016

I was trying to test as much scenarios as I can to hep You find the differences.

N37 · November 2016

Ok, so problem is solved a bit I think.

I have downloaded firmware from configurator where i have just enabled the smart graphic controller.

No other changes.

And LCD works, and works fine over reboots.

Works fine over power off and power on.

So it must be a problem in configuration i wanted to have.

I will start enabling things one per firmware and test it.

I have hope, that i will find this way the source of LCD problems.

I will post my results.

DId you try to flash the firmware according to my setting in the same setup arduino ramps and lcd ?

https://drive.google.com/file/d/0B4X4QYpSs7s4RnFKRFlJRVZfZ0U/view?usp=sharing

mabe You will find the problems in configuration.h faster than I.

But as clean firmware works fine we are in hope that the problem is not a major bug, and might be not a bug at all...

N37 · November 2016

Ok, so I have made full configuration with same settings than before.

I have configured everything I need right now, but i have made no changes in:

Start screen delayUI_START_SCREEN_DELAY

[milliseconds]

Time between page switchesUI_PAGES_DURATION

[milliseconds]

And firmware works fine and LCD works fine, even over the reboots.

Is it possible that changing those things from default was causing the problems ?

I just feel stupid. it's impossible that both of us could not see that at start.

I'll be testing the firmware over the night

Strange thing, configuration for Yaxis (this is Prusai3) is working different now.

Homing works fine on x and Y but Z is very slow, like 1 step or 2 steps per second, but configuration file is set to differen amount.

Srange, LCD stared working now steppers have got wrong timings, im starting to be a bit prustrated.

What should be the valu for y axus when used m5 treated rods with 0,8 standard spacing, when steppers 1.8" 200 steps per rotation are using microstepping 1/32 ?

200x32/0.8= 6400/0.8= 8000 ?

Because i use that value and it was fine til 30 minutes ago.

Repetier · November 2016

Absolute speed limit is 40000hz so with 8000 steps per mm your max. speed is 5mm/s. But you should stay away a bit from this especially with glcd display.

Look also into eeprom settings with all these switches if the steps per mm is set there correctly.

N37 · November 2016

I'm sorry for my frustration.

I'm glad that LCD is working.

I have traced the Z axis moving problems to the EEPROM.

I was using EEPROM set1 and 2 , and those values are now messed up.

Firmware has got by default values set in EEPROM, and is ignoring the configuration in configuration.h when flashing back "preconfigured firmware.

Question:

How can I clear EPROM1 and EPROM2 ?

Is there a menu entry to clear EEPROM ?

Because i see read from EPROM and Save to eprom but i can not see "clear EEPROM"

That should definitely help.

N37 · November 2016

Hello,

Printer works,

X, Y, Z, works fine.

Heated bed heats up to proper temp

Extruder also.

But i cannot get the extruder 0 fan to work.

I have got 1 extruder heater and it is connected to D10 (works fine)

one heatewd bed, connected to D8 (works fine)

And fan on D9 (configured as extruder 1 in configuration toll) <== is it right ?

Or if not, please advise what pin in online configuration tool should i Use , and where is the connector on RAMPS 1.4 relative to that pin you advise.

That will close the problems with beta configuration.

waiting for your adivise.

Repetier · November 2016

We have only one EEPROM set. EEPROM_MODE determines if we overwrite eeprom or not. Changing mode between uploads puts new values to eeprom, same keeps them.

M502

M500

would also copy configuration.h values to eeprom.

> And fan on D9 (configured as extruder 1 in configuration toll) <== is it right ?

What does that mean?

D9 may be used by extruder 1 (0 is first extruder) heater, normal fan (M106/M107 controlled) or cooler fan. As soon as you assign more then one function to that pin, you will not get what you expect as several functions modify pin as needed. So watch out with that. Not sure what exactly you did from this.

N37 · November 2016

i have definied only one extruder (extruder 0) and i use D10 connector on RAMPS 1.4 as extruder heater, so it is default configuration for that setup.

Heated bed uses D8 in my configuration so it is also default setup.

So D9 connector is not used at all by any hardware right now.

I need a etruder fan (fan that is cooling the extruder radiator. And i have set in configuration tool that this fan exactly extruder cooler pin that as i understand defines the fan for cooling extruder 0 that it should use Heater 2 normaly used for extruder 1, so I understand that this is D9 on RAMPS 1.4.

and it is not working.

That pin is not defined for any other accesroy than the fan.

That's why i was asking about is it right to do what I have done, and if not or if different aproach is better then to what pin should I rediret the output to run the extruder fan.

The board is fine, electronics are working fine. so no idea why that configuration is not working.

Repetier · November 2016

Make sure you have fan support disabled in features. That also uses D9 to control the fan. Also note that you can not explicitly control cooler can defined in extruder setup. That one is enabled by extruder temperature.

N37 · November 2016

" Also note that you can not explicitly control cooler can defined in extruder setup"

That was my case.

I assumed that setting the fan speed in % in menu wil override the automatization of fan.

I thought that if I will set 25% manually in menu it will start spinning the fan 25% of ful speed regardless of the extruder heater temperature and power timing.

That info should be added somewhere to claryfy the usage of that menu setting as it is not clear (i'm not so clever after all to gess the assumption properly :] )

Fan works fine when extruder heats up. Just on cold run it was not working even when i set the let's say 25% manually for testing purposes, I've had wrong understanding of manual percentage setting in menu. I thought that it will be kind of force usage of fan regardless of the actual need (temperature)

So now i understand the philosophy and it works fine according to the implementation of that function logic you described. So no prolem here. My fault.

Repetier · November 2016

Extruder cooler are a different thing then filament cooler. The first is for extruders needing a short cooling zone, the latter for fast cooling of filament extruder (PLA) which is also the one controlled in speed. Speed should be adjusted to fialment type and temperature.

N37 · November 2016

Ok, that makes the things crystal clear.

So last one fast question, what is the FAN1 and FAN2 PIN in default configuration of repetier assigned ?

Exactly where on board i can find that FAN1 pin ? *assuming default configuration using webconfig)

And I have had same LCD "glitch" when i have enabled the EEPROM in firmware and beeper at the same time.

The beeper was beeping in loop and lcd was flickering.

Disabling beeper helped, now everything works fine besides the beeper (not necessary for me so i'm not bothering with that problem now, but just pointing to potential bug.

I'll post firmware and config after testing at the end of the week because next 3 days i'm away from the office on meetings.

Repetier · November 2016

For RAMPS fan pin is D9, second fan is not preset at all. But you can always use the digitalpin number directly if unsure.

Marco67 · February 2017

Same issue here today with "TriGorilla" board (RAMPS compatible) and LCD2004A.
After some minute during printing the LCD start to show random characters, and after other minutes appear two square files and nothing else, but the printer work fine with USB.
After this event the display stops working forever, even turning off and on the power supply.
If I try to be welded with the soldering iron again the EXP1 pin on the board the display back to work but I notice that the EEPROM parameters have been cleared, now I don't know if due to possible electrostatic discharges caused by hot solder.
I rewrite my parameters, and after some minutes of printing same issue.
Now it would be nice to understand why this happens, if it is caused by continuous eeprom writings or other.

Repetier · February 2017

You mean AVR eeprom? Why should that change if display does not display correctly, so maybe in deed during soldering. Our rules for resetting eeprom is clear - eeprom mode different or checksum doe snot match any more so any changed bit would cause a reset. The display errors are just from wrong signals and then when flow is out of sync new data gets wrong meaning as it is at wrong position. I have one where it gets out of sync when bed cable comes too close. That is already enough. Also cable length and many factors can have influence.

pomonabill220 · August 2017

I am running an arduino mega 2560 R3 with the discount full graphics controller, and noticed a very similar problem.
After a few minutes of running, my display would go nuts, and I noticed the back light would flicker.
I measured the Arduino's 5v regulator's temp, and it was 240 deg F!!!!!!!! WAY too hot! and the regulator was shutting down because of over temp power shutdown. Max temp is 250 deg F.
I wired in an external regulator on a heat sink and problem solved!

LCD Full smart graphic controller - not working after some time
