"Incomplete Connection" on Both Projects

Hi, I am working on the claw machine PCB, again. I was wondering why this error showed up on both of my projects: "Incomplete Connection, please check." I have wired everything (except the ground of everything, which I will use a GND pour with), but the 12V net and the 5V net is showing incomplete for some reason. But, the rest is fine. So, I don't know.

Yes, I have turned off ratlines, too.

If you turn off the ratlines then you will not see the ratline showing you the incomplete connection. To help find the incomplete connection you should turn off the visibility  of everything **except** the ratlines (and maybe the silkscreen layer). :)

You seem to have two ground nets named ArGND and GND. And two 5V nets called Ar5V and 5V. Also, the two ground pins on the A4988s are connected on the schematic but not the PCB - is the schematic different for V13.1? Wait, the two grounds on the A4988s are 12VGNG and 5VGND. I'm confused. Mike.

@pommie Okay, so I have updated the schematic, so hopefully it makes more sense now. The V13 Schematic IS separate from the Version 13 and Version 13.1, so, basically, I have two projects that root off from that schematic, BUT are made in a separate project by me. If that doesn't make sense, let me explain it this way: I am using the schematic that I made to make those projects, but they are not made from that project, quite literally. I didn't choose to make a PCB from that same project. Where it says, "Design -> Convert Schematic to PCB." [Updated Schematic](https://easyeda.com/uptownkitten453/v13schematic)

@andyfierman Why are the ratlines not connected to 5V and 12V? ![PCBProblem.JPG](//image.easyeda.com/pullimage/Ei8QXCSJBCxFE3auJYydBwib4X1TM0CiJJtL5EUG.jpeg)![PCBProblem2.JPG](//image.easyeda.com/pullimage/5fJjic41QqtajBloCEChFoBuTxV5fAbuVX6AwFpm.jpeg)

I have gone back to fix several issues, so, hopefully, it make more sense: [New Updated Schematic](https://easyeda.com/uptownkitten453/v13schematic)

Here is the more updated (fixed) schematic: [https://easyeda.com/uptownkitten453/v13schematic](https://easyeda.com/uptownkitten453/v13schematic).

Okay, I think I see what the ratline does. It basically shows the incomplete connection.

Oh, no. I am wrong, according to this website: [EasyEda Ratline Tutorial](https://docs.easyeda.com/en/PCB/Ratline/index.html).

You still have a 5VGND going to your mega and nothing else (I think) - if so your mega will not be connected. Do you have two external supplies, 5V and 12V? Can you post consistent schematic and PCB files? Mike.

@pommie No, I have one power supply that goes to the Arduino and the stepper motors/actuator(DC motor). The 5V part was just me connecting all the parts that take 5V to the Arduino. The 5V GND was the total ground of the 5V parts. I have replaced it now with GND and the +5V part. I am also connecting the Arduino to 12V. I am unsure what you mean when you are saying to, "post consistent schematic and PCB files." I had to fix the schematic several times. I guess you don't want me to post the new link again.

@uptownkitten453, When you ask about a project, you should ensure that the PCB is up to date to the schematic. Having a schematic and a PCB that do not match just wastes everyone's time. If you have a project with more than one PCB from the same schematic, please clearly identify the PCB to which the questions refer.

@andyfierman Okay, I'll just start over and make the PCB with the schematic the same, instead of seperate.
