Buongiorno
sono un nuovo utente e spero di essermi messo su un argomento corretto altrimenti segnalatemi quale argomento usare
Ho un problema con la funzione ERC ( controllo delle connessioni dei componenti),
mi trova molti errori di componenti non collegati , pin di alimentazione (ho già messo il flag Power) ma anche tra pin di componenti vari (resistenza e condensatori)
Per cercare di risolvere il problema ho messo la griglia a 1 mm ma non ho risolto il problema
Qualcuno può aiutarmi a risolvere il problema ???
Grazie mille

Good morning
I’m a new user and I hope to have put myself on a correct topic otherwise tell me which topic to use
I have a problem with the ERC function (component connection control),
I find many errors of unconnected components, power pin (I have already put the Power flag) but also between pins of various components (resistance and capacitors)
To try to solve the problem I put the grid at 1 mm but I did not solve the problem
Can someone help me solve the problem???
Thanks a lot
Wires connect with other wires or pins only if their ends coincide exactly. Therefore it is very important to keep symbol pins and wires aligned to the grid. It is recommended to always use a 50 mil grid when placing symbols and drawing wires because the KiCad standard symbol library and all libraries that follow its style also use a 50 mil grid. Using a grid size other than 50 mil will result in schematics without proper connectivity!
I fili si collegano ad altri fili o pin solo se le loro estremità coincidono esattamente. Pertanto, è molto importante mantenere i pin e i fili dei simboli allineati alla griglia. Si consiglia di utilizzare sempre una griglia da 50 mil quando si posizionano i simboli e si disegnano i fili, poiché la libreria di simboli standard di KiCad e tutte le librerie che seguono il suo stile utilizzano anch’esse una griglia da 50 mil. L’utilizzo di una griglia di dimensioni diverse da 50 mil darà luogo a schemi elettrici privi di connettività corretta!
Changing the grid is the problem. In KiCad you should just keep the grid at 50mil, as retiredfeline already mentioned.
To repair your schematic:
Set the grid back to 50 mil
Zoom out and then select everything on the schematic.
Right click and select: Align Items to Grid from the context menu.
The reason the grid is so important is because KiCad determines connections between wires and pins by their coordinates. If the coordinates do not match perfectly (Down to a mill, which is 0.0254mm) then KiCad does not recognize the connection.
Also:
It is discouraged to use any other language then English on this forum. When you use another language, then there are very few people who can understand it, and more importantly, it also breaks the search functions on this forum. There are probably many more people searching though old forum topics to find answers, then there are people who post questions. It’s also more efficient you translate your own post, then let others translate it for you. Translating tools are ever becoming better. You can use online translators, but recently I discovered that there is even a translator built right into Firefox. Just select some text, right click and use the translate form the context menu.
