Dear all,

I’m encountering an issue while trying to route differential pairs in KiCad. The problem arises when I attempt to finish a segment during differential pair routing. I expect that clicking would finalize the current segment so I can continue routing in a different direction, but nothing happens when I click, and I can’t proceed.

It may help if you let us know what version of KiCad you are using ?

Can you paste your version info here please, you can get it from KiCad > Help > About KiCad > Copy Version Info

Try updating to rc2 which was just released. There were several router fixes between rc1 and rc2.

Are you using the router in shove mode? (if it’s the case, we’re already working on a fix)

I was struggling with the exact same issue. Then, by chance, I tried experimenting with Route > Interactive Router Settings. I have pretty much always used the Shove mode, but when I changed it to “Highlight collisions”, laying differential pairs began working perfectly.

FWIW, my version info:
