Outer layer restring. Do i have an error in my layout?

I would now like to have a circuit board created for my project. For this purpose, I have uploaded my Gerber data as a zip file at eurocircuits.com.

The website automatically checks the data and has issued the following warning: “The measured value for outer layer restring (OAR) (0.000 mm) does not match any of the available options.”
The problem seems to have something to do with the boreholes.
What settings do I have to adjust in KiCad to get this message no longer displayed?

Translated with DeepL Translate: The world's most accurate translator (free version)

OAR is annular ring. Do you have a PTH hole without the copper ring?

First the obvious: Are there DRC violations in KiCad?

How does it look in Ucamco’s reference viewer?

I am a beginner. sarcasm on >> Some say I’m the dumbest user they can think of. Others ask me not to ask so many questions. << sarcasm off. My 1st thought when I read your answer - for which I thank you by the way - was something like “What on earth is a PTH Hole”?..

thank you for your reply as well and yes, kicad has been grumbling that some footprints don’t match those in the library. The reason for these messages might be that I took for example (for “playful” experiments on the 3D representation) a potentiometer from Piher, for which there is no 3D symbol in the library, one from the web. That leads then, according to my understanding to the fact that KiCad recognizes this naturally and makes me attentive to it. Second, I had modified the 3D model a bit for an LM317T. I had changed the “insertion depth” of the connecting legs a bit - who noticed? KiCad.
But even removing these problems (DRC test runs through without error/warning messages) did not cause the warning message from the board manufacturer mentioned at the beginning to disappear.
To the link provided: If I understand it correctly, I upload my zip-file and can then use the icons on the right screen wheel to have the individual layers tested for errors. At the moment the Ucamo page reports me an error 502 Bad Gateway. Anyway, I have done the individual checks. No errors were found.

Usually Google gives good answers to “what does this or that word or term mean”.

PTH is a Plated Through hole. Manufacturers want “annular rings” around such holes (another case for Google…).

Yes, when you understand the language. If you have to translate it with a machine, it can be hard to even know what to search for and hard to find the correct answer.

What on earth is a PTH Hole

A hole with Copper on the inner wall of the hole, used for THT-Pins and Vias.
Did you create any mounting holes? If so how did you create them? You have to set them to NPTH - Mechanisch and not Durchgehende Bohrung. Durchgehende Bohrung places copper inside and should only be used when there is a conntact.

Deutsche Version

What on earth is a PTH Hole

Ein Loch mit Kupfer auf der Lochwand, verwendet für Durchsteckpins und Durchkontaktierungen.
Hast du Bohrlöcher platziert, wenn ja wie? Du musst diese auf NPTH - Mechanisch setzen und darfst nicht Durchgehende Bohrung verwenden, denn dieses wäre ein PTH und erwartet eine elektrische Verbindung.

Hallo Johannes. Schon als ich deinen Namen laß hatte ich die Vermutung dass ich hier auf einen deutschsprachigen Forennutzer gestoßen bin. Danke für deinen Beistand. Ich bin schon froh, dass es inzwischen so gute Übersetzungssoftware. Aber manches ist sowas von mühselig.
So, genug gejammert.
Jetzt habe ich verstanden. Die Bezeichnung “via” sagt mir was.
Solche Löcher habe ich nicht. Ich habe auch keine Bohrlöcher (zu Befestigungszwecken) angebracht.
Ich habe Versuchsweise mal die Größe der Lötpads an den Klemmverbindern vergrößert. Die brauchen relativ große Bohrungen. Hat aber auch nichts gebracht.
And here the German Version :wink:
Hello Johannes. Already when I read your name I had the assumption that I have come across a German-speaking forum user here. Thank you for your assistance. I am glad that there is such good translation software. But some things are so tedious.
So, enough whining.
Now I understand. The term “via” means something to me.
I do not have such holes. I have also not drilled any holes (for fastening purposes).
I tried to increase the size of the solder pads on the terminal connectors. They need relatively large holes. But that didn’t help either.

Can you post the project files?

Deutsche Version

Kannst du das Projekt hochladen? Oder wenigstens die Leiterplattendatei (*.kicad_pcb-datei)?

Ist ja nichts besonderes. Deshalb hänge ich auch mal den Schaltplan an.
In my english words: Nothing special. Im Uploading pcb and sch

Garagentor Steuerung.kicad_pcb (288.4 KB)
Garagentor Steuerung.kicad_sch (91.3 KB)

Please rather zip or archive the project. It’s annoying to try to open separate files. I don’t think you have custom DRC rules, but if a project has them they are in a dedicated file, and lack of it prevents testing DRC problems.

Mir ist nichts negatives aufgefallen, jedoch bekomme ich die selbe Fehlermeldung. Vielleicht müsstest du mal bei Eurocircuits direkt anfragen.

Didn’t see anything bad, but get the same result when i try to upload there. You may ask them

Meine Anfrage ist soeben rausgegangen. Mal sehen was die sagen…

My request has just gone out. Let’s see what they say…

Ich habe bei eurocirquits ein Konto eröffnen müssen. Dann konnte ich mir die Boards in deren Betrachter genauer ansehen.
Wie auch immer, ging eine Bohrung durch eine Leiterbahn und ich glaube es waren zwei weitere Bohrungen die dort im Board waren obwohl dort keine hingehörten. Es ist mir ein Rätsel. Im Leiterplatteneditor von KiCad habe ich nichts gesehen.
Ich habe nun ein neues, “sauberes” Projekt gestartet und nun hat alles funktioniert. Auch wenn ich die tatsächliche Ursache nicht nachvollziehen kann (die Ursache saß vermutlich vor dem Bildschirm) bin ich zufrieden. Das Ergebnis zählt.
Ich bedanke mich für eure Hilfe. Ein besonderer Dankesgruß geht an Johannes :wink:

I have had to open an account with eurocirquits. Then I could take a closer look at the boards in their viewer.
However, one hole went through a trace and I think there were two more holes that were there in the board although none belonged there. It is a mystery to me. I didn’t see anything in KiCad’s PCB editor.
I have now started a new, “clean” project and now everything worked. Even though I can’t trace the actual cause (the cause was probably sitting in front of the screen) I am satisfied. It’s the result that counts.
I thank you for your help. A special thanks goes to Johannes :wink:

Das ist schon ein wenig merkwürdig, ich habe die Gerberdaten angesehen (in Gerbview von KiCad und Gerbv, eine komplett andere Software) und habe bei beiden nichts gefunden das ein Problem ist, kein Bohrloch im nirgendwo. Naja, wenn es funktioniert ist ja gut.

It is a bit strange, i controlled the gerber files and didn’t found anything that could have caused the problem, no drill hole where i didn’t expect one. But anyway.
