Strange that they got misaligned in the first place, they are the same footprint, placed on the same grid... > The DP placement algorithm can't place the > "kinks" between pairs of unaligned pads automatically.

If I move both again to align, they do indeed seem to be able to connect. Another possible issue or oddity: Is it on purpose, that when routing differential pair from c net from the bottom and north, click aproximately directly south of a pad on top to the right, that when the cursor is north and between two pads it will not route through? > I'm open to improving it in the future. > > Cheers, > Tom > > >>>> >>>> Hi Nick, >>>> >>>> Could you send me the PCB where the problem occurs? >>>> >>>> Cheers, >>>> Tom >>> >>> Sure, no problem. see attached. >> >> Even if I shift the bottom connector to the right, it won't connect >> directly.
