No image generated / info displayed, but start with high %

[ilpantera]

First of all: Thank you very much for the great work. Saw the screenshots and it looks great! I have installed it but am facing an issue: Neither the image, nor the info is displayed on my Neptune 3 Pro, however the print starts with 40-50% on the progress bar. As soon as I delete

;includeThumbnail
;includeTimeEstimate
;includeFilamentGramsEstimate
;includeLayerHeight

From the Start G-code, everything is back to normal. Any idea? Thanks a lot!

Hi,

interesting issue indeed. First of all thanks for all the details. I found out, that they look exactly like mine and I also use the Neptune 3 Pro. Therefore the Problem must be somewhere else. What do you meen by info not displayed? Do you mean the one in the thumbnail the Info below the thumbnail?

Can you tell me which Cura version and plugins (click on the Marketplace button and then the settings wheel to view installed plugins) you have installed? I am thinking, that other plugins might mess with mine.

Also, you could send me the created G-code file if you want to. I think that could give some hints on what the issue is.

Edit: Which firmware version does your printer have installed, is it up to date?

Best regards

[ilpantera]

Hey, yes super strange issue. Thanks for checking the G-code.

Cura Version: 5.3.1 - no other plugins installed Neptune 3 Pro Firmware: 1.1.5.1a UI Version V1.4.1

Here is how the screen looks like right after clicking "print": https://1drv.ms/i/s!AnDUX6Ggc6C3go8eUGqPsvYVEcrM3A?e=3JJguh

Should all be the latest?

[Molodos]

Actually there is a newer Firmware available: Mainboard: 1.1.5.1b UI: V1.4.2 But as yours is pretty new, too, I think that shouldn't be a problem. If it was, then more people would have problems.

Would you be so kind to send me the gcode, that was generated (the one on the sd card you were printing)? I think this might be the only chance to find the problem as everything else seems pretty much like my working setup. If you do so, I could try starting the print on my printer and check if I can reproduce the error.

Edit: If you want to, you can additionally send me a version of the gcode generated when you remove the plugin commands. This might make analyzing easier for me :D

[ilpantera]

Thank you! Here is the very simple file as an example showing the above error (with plugin) and working fine (without plugin).

Thanks for the files. I just had a quick look and found out, that the Thumbnail is indeed formatted wrongly. Thats good news I guess. I am currently away and will only be able to try hunt down the bug the day after tomorrow. Until then, I have one more thing that might help me: Could you generate G-code for your Neptune 2 printer that is working with the same object and thumbnail enabled and also send it to me? Sorry for the many things I need, but I think we are on a good way to hunt down the issue :D

[ilpantera]

No worries, I'm in no hurry - thanks for taking the time to look into it.

Btw. I am running Cura on Win11.

I think there is a misunderstanding. I don't have a Neptune 2.

[Molodos]

I am sorry confused you with another one who hat a neptune 2. I will look into everything tomorrow. (Btw: I am also on Win 11)

I think your issue is different. Are you sure, that your printer is also starting at 50% progress? If I look into your G-code, it does seem like another problem as there are no clues pointing towards this issue. I am happy too help, but if I am right and your issue is a different one, please open a new Issue for that, thank you :D

[Molodos]

@ilpantera I think I have found the issue. You seem to have used an Ender 3 printer as a base for your printer profile. As my plugin needs to find out, which printer model is used (different Neptune printers use different thumbnail formats), this will lead to errors. I have planned to release a fix, that no thumbnail is generated instead of leading to display errors, but you can fix it for you by using the official Elegoo Neptune 3 Pro printer definition, that comes with Cura, as a base. Please let me know if that fixes it for you :D

[ilpantera]

Ahh, thank you makes sense! Where can I find the Elegoo Cura config? This is one that was shared on YouTube for the Neptune 3 Pro as working well (and it did so far).

[Molodos]

Just open tha Add printer dialog in Cura and select "Non UltiMaker printer" >"Add a non-networked printer" >"ELEGOO" > "ELEGOO NEPTUNE 3 PRO". I know some time ago you needed to use the Ender 3 as base because there were not Elegoo definitions in Cura. But now they were added so you can just use them :)

[ilpantera]

Ah cool, thank you very much! This worked for me, Thumbnail is displaying correctly. However now the % progress does not move away from 0%. Any clue what could cause that?

[Molodos]

Happy to hear that. To be honest, I have no idea on what could cause the % error. But if it works without the options for the plugin added to the start G-code, one could compare the two G-code files and might find something. I guess there should be some differences that would give some hints on the error. If you want to, you can also send me those and I will have a look if I find some time :D

[Molodos]

As there ius no more activity, i will close this issue as fixed :D
