Okay, I see what you're referring to. This is = a bug in the tutorial. It looks to me like the first set of figures were cr= eated with an older version of PCB and the other set with a newer one and a= later date. What likely happened is that the same circuit was used, but th= e schematic was redrawn when the new figures were added, and because the pa= rts would have been arranged differently, the reference designators ended u= p changing. The underlying circuit appears to be the same, just the names o= f the parts have been swapped. You can even see that the footprint of R101 = is different.

Ultimately, the rat lines on your pc= b should be consistent with the connections you made in the schematic. So, = as long as you connect your parts accordingly, you should be fine.

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

Hi Chad,

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 d= ue to footprint name errors. The second time (and all subsequent times) you= run it, it produces board.new.pcb, which contains the new elements,= so that it doesn't overwrite your original file. To get them into the = layout, you have to do as it says: open the layout then go to the file menu= , select "load layout data to paste buffer", and select board.new= .pcb. Then you can paste them into the layout.

Alternatively, if you haven't done any work on the pcb yet, you can de= lete board.pcb and board.new.pcb and rerun gsch2pcb.

Also, make sure that you execute Select > Disperse All Elements, as s= ometimes the elements will overlap when they're brought into the layout= .

Cheers,
--Chad

Hi Torben-

Welcome to the community! Please = feel free to post any questions you may have.

= I think the issue is that the CONNECTOR is no longer an m4 element, so, it&= #39;s not generating it the way the tutorial thinks it should.

Looking through the pcb element footprints, there is, how= ever, a footprint "CONNECTOR 1 2". I suspect that will serve for = your purposes. Please try changing "CONNECTOR 2 1" --> "C= ONNECTOR 1 2" and see if that fixes it.
