The square terminal generall= y indicates "pin 1" of the device. This is done so that when you&= #39;re installing the components, you know the proper orientation. For some= parts this is important, like for the opamps in the design. For other part= s, like the resistors, it doesn't matter, they can go either way.

Part of the fun of building a circuit board is figu= ring out where to place the components and how to connect them, kind of lik= e a puzzle, but with no one answer. You can place them however you like. Ma= ny people use a strategy where you try to place the parts such that you min= imize the lengths of the traces connecting those parts. You could also arra= nge them in a pattern to resemble a bug, or a star, or anything you find ae= sthetically pleasing. In most cases (i.e. not radio frequency or high speed= (>10s of MHz) digital electronics), the exact placement of parts doesn&= #39;t matter.

Okay,= I see what you're referring to. This is a bug in the tutorial. It look= s to me like the first set of figures were created with an older version of= PCB and the other set with a newer one and a later date. What likely happe= ned is that the same circuit was used, but the schematic was redrawn when t= he new figures were added, and because the parts would have been arranged d= ifferently, the reference designators ended up changing. The underlying cir= cuit appears to be the same, just the names of the parts have been swapped.= You can even see that the footprint of R101 is different.

Ultimately, the rat lines on your pcb should be consistent with th= e connections you made in the schematic. So, as long as you connect your pa= rts accordingly, you should be fine.

Thanks fo= r pointing this out. We should fix it so that it's consistent.

Thanks,

Hi Chad,
I am confused by the UBUNTU geda tut= orial.
In the beginning R101, R102 and R103 are pla= ced together. On page 6=C2=A0 R102, R201 and R103 are placed together in th= e same place and R102 is placed where R201 was before.
I have other problems - fx with lines created in PCB - but I would take= one example to see if the confusion is my problem.

Hi Torben-

The = second time you run gsch2pcb it looks at the differences. The first time it= may not have picked up all of the elements due to footprint name errors. T= he second time (and all subsequent times) you run it, it produces board.= new.pcb, which contains the new elements, so that it doesn't overwr= ite your original file. To get them into the layout, you have to do as it s= ays: open the layout then go to the file menu, select "load layout dat= a to paste buffer", and select board.new.pcb. Then you can paste them = into the layout.

Alternatively, if you haven&#= 39;t done any work on the pcb yet, you can delete board.pcb and board.new.p= cb and rerun gsch2pcb.

Also, make sure that you ex= ecute Select > Disperse All Elements, as sometimes the elements will ove= rlap when they're brought into the layout.

=C2=A0=C2=A0=C2=A0 to update the pin names of all footprints.=

If I folllow the instructions above I add the one.sch to th= e screen all bundled up. Both one.sch and two.sch appear to be OK.

As I say, I am confused.

Hi Torben-

<= div>Welcome to the community! Please feel free to post any questions you ma= y have.

I think the issue is that the CONNECTO= R is no longer an m4 element, so, it's not generating it the way the tu= torial thinks it should.

Looking through the = pcb element footprints, there is, however, a footprint "CONNECTOR 1 2&= quot;. I suspect that will serve for your purposes. Please try changing &qu= ot;CONNECTOR 2 1" --> "CONNECTOR 1 2" and see if that fix= es it.
