In some cases, the router refuses to connect traces.
Kicad3
Does anyone know what can happen? In some cases, when the traces is too big,
it refuses to start, but at least there is a good reason in this case. But the trace is 0.125mm,
and there is no obstacle. Beside this, I could route it when starting from the other end.
Even when KiCad is in the Release Candidate phase you should use Help -> About -> Copy version info and paste the whole information.
You may have some item there which prevents connecting. Try outlines modes for tracks and pads (in the left hand toolbar) to see objects lurking behind others. Make also sure the object visibility is on for all items in Appearance -> Objects.
It’s usually working. For instance, all the traces on the left were routed without any problem.
Only this trace had this issue. And writing it from the other end also worked, and that’s why it’s quite strange.
I haven’t tried to click intermediate points. But I will nexte time it happens (if it does).
