Ender 3 V2 Neo support

[adrianocr]

I'm wondering if the new V2 refresh (Ender 3 V2 Neo) can be added to this project. It comes with auto leveling and some slightly upgraded internal bits too and a new screen but I think the mainboard is the same as the standard V2. It also runs a version of Marlin Firmware.

[mriscoc]

Test with the Ender3V2-422-BLTUBL firmware version.

EDIT: Some users have found that their Ender-3 V2 Neo needs a display firmware update for a proper boot if the printer has a TJC display.

Since some Ender 3V2 Neo's are coming with GD32 SoC, I suggest you check your printer board. Currently only STM32 SoCs are officially supported. Many people reports a successful installation in their GD32 boards, but some others got a soft bricked printer. That brick was successfully fixed by changing the SD memory card with a correct size and format, and flashing the stock Creality firmware.

If you got a completely black screen or just a screen with the Creality logo on it, try with another SD card, format it properly, rename the firmware to something unique and short, also try with the display firmware update if your printer has a TJC display.

[mriscoc]

Check if you installed by mistake a 4.2.7 version in 4.2.2 board.

[FrazzyDK]

Just installed 4.2.2.
It works great now.
Thabk you so much :D

[FrazzyDK]

And fyi i got the GD32f130 Chip, but it works :)

[MatthewYoussef]

hi, I wondered if the ender 3 neo is compatible to with your software. myself I have an ender 3 V2 neo and this software changed my printing life. now at school (mechanical engineering study) every group got his own printer, an ender 3 neo. i would like to flash your software on it, but can't find whether is compatible or not

[mriscoc]

Only if the printer meets these requirements: https://github.com/mriscoc/Ender3V2S1/wiki#requirements

[adrianocr]

@mriscoc that actually worked great! The only concern so far is that I'm not sure I got the physical settings correct. Do you have any tips on how to find the correct values? Once again it seems that the V2 neo is so recent that a google search came up blank.

The firmware seems to start off at 230x230x250 but the V2 Neo is actually 220x220x250mm so I adjusted that and subsequently tried manually moving the axes around and came up with x min -26, y min -26, x max 218, y max 205, and z max 250.

Additionally I had to manually set the prove offsets to x -21 and y (+)7 to set the prove right in the very center of the bed like the stock firmware does it. That's the correct approach, right? Or should it be off center like this firmware?

For anyone in the future that sees this: those values may be slightly incorrect.

[Vannion]

currently 10. even at 40 saving and rebooting, it still printed off the bed. That all part of the calibration steps. that don't seem to make a difference. Just verified increasing min x, saving rebooting printing. print is in exact same spot to the left.

[Mysteoa]

It should be negative number. For mine V2 Neo is -4, but it is using the Sprite hotend. I don't know what it was for the stock hotend.

[Vannion]

I was just figuring it out. after looking at the little drawing. very counter intuitive, since we are moving things to the right.

[gonzojournalism]

This worked for me, i was running into the same issue ,This is my G-Code in Cura.. Change your start G-Code in which ever Slicer your using ..Where it say G1 X6.1 and 6.4.

[mriscoc]

Thanks for your report, XY MIN/MAX Position and other physical settings can currently be found only experimenting like you did.

Ender 3 V2 Neo now has made the thumbnail preview work on DACAI screen, It is very cool if you add this to your project. This is what of us have been waiting for.

[mriscoc]

Ender 3 V2 Neo now has made the thumbnail preview work on DACAI screen, It is very cool if you add this to your project. This is what of us have been waiting for.

Are you sure that they are DACAI? I did receive reports that they are using fully compatible DWIN screens.

[adrianocr]

@mriscoc it does seem that my unit also has a DACAI screen but this firmware with the DWIN files (to the best of my understanding) works flawlessly too.

[ssrshark]

I owed Ender V2 Neo, the screen they used is DACAI, I update screen firmware with Private not DWIN.

[mriscoc]

@mriscoc it does seem that my unit also has a DACAI screen but this firmware with the DWIN files (to the best of my understanding) works flawlessly too.

Is the Professional firmware showing the preview when you try to print this demo G-codes? :
demo.zip

[mriscoc]

I owed Ender V2 Neo, the screen they used is DACAI, I update screen firmware with Private not DWIN.

Good to know. So, they updated the firmware for the DACAI screens, please test with the provided demo G-codes and Professional Firmware.

[ssrshark]

Professional firmware for 4.22 board, shown blank while preview on screen, we have to use their 4.2.2 firmware and the "Private" for screen which Creality privide to in order to make it work, I think if you check for it you would make it work.

https://www.creality.com/pages/download-ender-3-v2-neo?spm=..page_1934481.products_display_1.1&spm_prev=..page_1934087.header_1.1

[mriscoc]

Only binary files were published, we need to have the official sources or the API information for accessing the newly implemented functions on the DACAI new firmware.

The users of that printer can request to Creality to disclosure the Official source code for the Neo printer.

[adrianocr]

The users of that printer can request to Creality to disclosure the Official source code for the Neo printer.

By email or is there a special request process or something? I wouldn't mind doing it.

[mriscoc]

By email or is there a special request process or something? I wouldn't mind doing it.

Use all the channels as possible, mail to support, request in the Creality repository, etc.

[ssrshark]

I have contacted them via email couple day ago about the instruction how to generate thumbnail preview on screen, but they provided me with the useless instruction, but I have found that to generate preview thumbnail they use this slicer "
Creality_Print" "https://www.crealitycloud.com/software-firmware/software" there is an option in printer manager to generate thumbnail to Gcode.

[adrianocr]

@mriscoc so I'm having an issue where it seems I am incapable of getting the bed properly centered. Any tips?

I've set the bed size to 220x220 (even though if you actually measure it with something it is actually around 235x235) and I have manually tested all the end stops to come up with the X max and Y max, and manually centered the probe offsets by placing a dot in the direct center of the bed with a sharpie and then painstakingly centering the probe until it perfectly touches that center point (interestingly here the measurements I get with my caliper are off by 3mm on the x axis and a whole 11mm on the y axis). Auto home seems to work correctly and the device perfectly probes the direct center of the bed during homing.

However when I go print something the prints are always about 3-5cm left of center. I've tried prusa slicer and cura and manual gcodes.

Any suggestions on what could be going on and how I could sort it out?

[matty]

I upgraded to 20230312 and did a manual calibration, I was using a previous firmware (forgot which version unfortunately), I also did a PID tune on the nozzle and sensor but I am getting an error when preheating where it fails to heat.

The autotune however does heat successfully. Not sure what is different?

[mriscoc]

Ender 3V2 422/427 20230312 uses MPC not PID for the nozzle.

[Mammosz]

Ender3 v2 neo bordversion v4.2.3

Find out. File congfig🙏🏻

[laenzlinger]

I have just bought an Ender 3 V2 NEO. Mine has a 4.2.2 board with a TJC screen.

[FrazzyDK]

Me too, I succesfully installed ender 3 v2 firmware on it :)

[AbacusCosinus]

Installed the latest (now withdrawn) version Ender3V2-422-BLTUBL-MPC-20230805 on my Ender 3 V2 Neo (4.2.2 with GD32F303) few days ago. Works just great.
One thing I noticed is that if I run a Auto Build Mesh with Multiple Probing set to 2 it throws firmware errors "... failed to probe...", tried with 9x9, 8x8, 7x7 and so on. Errors always shows up at the same point eg. 49/81. As soon as Multiple Probing is set to 0 it works just fine.

[mriscoc]

Look for HS off in Issues, discussion and the Wiki.

[AbacusCosinus]

Awesome, this did the trick! Works just fine now!

[jvhemmer]

Is your screen TJC or DACAI? I'm not able to install it. What size SD card did you use?

[neilhl1979]

I installed professional firmware a few days ago then realised that the mesh numbers weren’t displaying. After checking back I see I need the special compile for tjc screens. putting the bin file on the SD card like I did for the previous bin file doesn’t do anything. Am I unable to flash to the tjc firmware from the normal firmware?

[mriscoc]

Format/Change SD card, rename firmware file.

[neilhl1979]

I tried format and renaming but I'll get a new card and try that. Worked perfectly the day before putting the non tjc firmware on :(

[Dakweed666]

You are putting the sd-card in to the motherboard on the screen not the slot on the front of the printer??

[neilhl1979]

No I updated the screen with the tjc set but the tjc bin file I’m using the printer slot as normal for firmware updates

[walpow]

I installed the latest version of the firmware; the install went off without a hitch, and it's running perfectly on my V2 Neo. But the display update is another story. When I put the unzipped private folder on my MicroSD (I've got the Dacai board) and booted up, it seemed to install the files, but after the screen went blank the printer wouldn't boot.

I was able to get it going again by putting the full display firmware, along with the original image and font files, on a MicroSD and rebooting; after seeming to install the files it rebooted normally, but the files weren't displayed. Then I got the bright idea to boot the display with the original firmware and the new files. Again it seemed to install the files and reboot correctly, but the files aren't being used.

To sum up:

1. The machine won't boot after installing image and font files unless I also put the display firmware in the root.
2. It seems to install the files but the printer isn't displaying them.

Thanks in advance for any ideas.

[mriscoc]

Maybe related to: #966

[walpow]

Thanks for the quick reply. That does look like it could help. I'll check it out and report back.

[walpow]

Sorry to say nothing there helped, and after trying the stuff in it I can't get the display the work at all. They suggested an additional file to flash, and now I think it was only for the S1. Anyway, I bought a new display on Amazon, and it arrives today.

[walpow]

New display working. I'm going to hold off on updating the display firmware.

[HipolitoLopes]

Just installed the ENDER3V2-422-BLTUBL-MPC-20230809 with sucess !
At least it looks like !
My machine is a ENDER3V2 422 equipped with a DACAI screen and a GD32F303 chip.
First tests I did without messing up with X/Y MAX/MIN were sucessful, dimensional was right, model has been printed at the center of printing table.
Just did some X/Y MAX/MIN calibration and printing a 20mm test block ! Lets see !

Edit : It is indeed a success !

But ... The leveling system is way more sophisticated than the original one. So one should consider go through some videos and instructions on how to use the leveling system ! It took me a couple hours until I could understand and apply the new workflow.

This firmware turns a toy into a useful tool!

[CruisnGrrl]

Also have the same config on my e3v2neo, thankfully haven't needed to update the screen firmware. installed with out a hitch.
used a lexar 4GB tf card formatted as prescribed that I keep around for this sort of thing.

[nsch2308]

Hello, i have a problem with saving axis, i have a warning "Current Position is Unknow" X0, Y0 " i can't save my config after a homing, when i save the homing, when rebooting, the config come without my new config, and "Current .... " always, what can i do for modify X0 and Y0, and save it correctly , thanks for attention, i have a Ender 3 V2 Neo
Nicolas

[nsch2308]

I lost all my configuration, the x and y axes send the extruder to the left and force the belt with an infernal noise, and I'm afraid to use home x or y because it's hell, when I turn on my printer, no configuration , and it's in a loop, what to do, who can advise me on how to reset my x and y axes correctly 🤪  Nicolas ***@***.***

[mriscoc]

Flash stock firmware, load defaults and calibrate your printer until your get a good working status, take note of your configuration, upgrade your firmware and configure it with the values previously noted.

You can use M503 and M115 to get your actual settings.

[nsch2308]

I thank you for your wise advice and your good attention, one day on Youtube, I had skimmed the setbacks of an enthusiast who was disappointed by his printer problems, he had finally noticed that everything seemed linked to the limit switches, I then realized that my problem perhaps came from there, I slightly moved my X and Y end stops, and Miracle, everything is back on track, thank you again for your support Nicolas De : Miguel Risco-Castillo ***@***.***> Envoyé : vendredi 8 septembre 2023 19:03 À : mriscoc/Ender3V2S1 ***@***.***> Cc : nsch2308 ***@***.***>; Comment ***@***.***> Objet : Re: [mriscoc/Ender3V2S1] Ender 3 V2 Neo support (Discussion #413) Flash stock firmware, calibrate your printer until your get a good working status, take note of your configuration, upgrade your firmware and configure it with the values previously noted. — Reply to this email directly, view it on GitHub <#413 (reply in thread)> , or unsubscribe <https://github.com/notifications/unsubscribe-auth/ARFAH7Y2BJ55SS3W4CE4WIDXZNFT3ANCNFSM6AAAAAARA45EEQ> .

There are five kinds of display units, you must compare yours with the pictures at: https://github.com/mriscoc/Ender3V2S1/wiki/How-to-update-the-display There are also the instructions for updating them if necessary.

Ender 3 V2 Neo || 4.2.2 || TJC

For whoever is trying to find a starting point for the Load/Unload Filament settings, mine seemed to work well on the following:

• Load: 385mm
• Unload: 435mm

Seems to be working fine every time, if there might be any unwanted friction in the tube, you might want the unload upped by ~20mm.
450 to 460mm should be working for everyone.

No runout sensor, just wanted to change the filament easier.

I'm using these start and end codes in CURA. Are they correct?

Isn't G29 needed for the Neo? Or is M420 with a mesh better?

[mriscoc]

Ok tnx!

For the END code? I use your firmware in combination with OctoPrint.

Isn't that double config? What's best practise? Remove M104, M106, M140 and M84 from Cura or from OctoPrint?

[mriscoc]

The Octoprint end script is the last one to be executed, there is not interference with the Slicer end-gcode script.

Thanks! I was able to format the 64 GB SD card as FAT32 using 4K cluster size with MiniTool. Though I still get stuck at the boot screen. I can revert back to the original firmware easily but not install this one. I'm out of options.

[mriscoc]

Connect the printer to Pronterface and check if you can control it, I suspect the problem is the display firmware.

I've found best results using an old 4GB microSD card that I only use for flashing. Anecdotally I've noticed on the Community Discord that people have problems with 32GB and up regardless of how they're formatted No trees were harmed in the sending of this message, although a sizable number of electrons were terribly inconvenienced.
