I’m trying to figure out if I have a real issue here, or if KiCAD is just having a brain fart. I have two TL072s running in parallel and one of them is throwing this error when I run ERC, but the other is not. They’re literal copies of one another driving two identical copies of a circuit. Is this post destined for the dumbassery thread and I just haven’t realized it yet?
I usually just shut that error up by throwing a power flag on the power header pins. It seems arbitrary cuz sometimes I don’t get that error at all.
If the op amp power pins connect in PCBNew it should be fine regardless of whether you use a power flag or not.
I tried that actually. It then gave an error that there were two power sources on each rail ![]()
What happens if you use the “conn02x05” (or whatever it’s called) symbol instead of what you have there?
Good suggestion. Unfortunately I get the same error using that symbol. (The one I had in there before is from @analogoutput 's library.)
I think I have it sorted now though. For some reason it still threw errors if i put PWR_FLAG on the net next to the power connector, but if I put the PWR_FLAG all the way to the left by the +12v/-12v inputs, it worked.
Either that, or the ritual sacrifices finally paid off.
