Well it looks like you have "vb" coming off the supply filtering and "-vb" on the main circuit. If you mean for them to be connected, change the -vb to vb. If you don't mean for them to be connected there is nothing connected to vb or -vb.

Ah, I see. I have used differently labelled pads. Thanks.

What is the difference between using the LINE tool and the NET tool to connect components? I have watched a couple of Eagle video tutorials where the Line tool is used to connect components but I have also that using the Net tool is recommended to connect components.

From the official tutorial: "Do not use the WIRE command to draw net or bus lines in the schematic. Use NET or BUS instead!"


Definitely recommended to read instead of watching videos by experts :wink:.

I agree. I should have read the official documentation first. :slap:

Crap! So I should have been using the Net tool and not the wire tool all these years!!!! :oops:

Yes..

This will help you ensure everything in your schematic is connected properly in your PCB too.

If this is in the wrong area please let me know.

I have a design I want to share in the Ready To Build Projects if I can ever get the PCB portion done.
I’m using an opamp to create my ½ voltage reference. When I check for errors on my schematic I get the following errors;
OUTPUT and SUPPLY pins mixed on net VR. Also the POWER going to my opamps show a warning. Is it ok to approve these or is there something that I’m missing in the layout?

Thanks!

As long as "the error makes sense", it's okay to approve ;) I've had quite a few PCB's fabbed, with the two errors you've just mentioned. Those are more like "Are you sure this is how you'd like stuff done?" messages 8)
The reason the power pins throw an error is that they will automatically connect to certain nets (V+ and V- i think). The one with output pins to supply nets - no idea...
