How to have Kicad automatically connect joints not perfectly connected just by 1-2 px, clearly told by 2 hollow/empty circles instead of smooth nothing there or a solid dot
It seems as though you have some elements âoff gridâ on your Schematic.
To fix the problem select the whole schematic then Right click anywhere on the schematic and then select: âalign elements to gridâ.

But, be careful when you do this!
Even though this will fix connection problems in the future, moving components to the correct grid may unintentionally connect wires - look over your schematic carefully when you issue this command.
And donât use a grid of anything other than 50 (units) when laying out your schematic. KiCad relies on default connection points being on this base grid. Only ever use a smaller grid to move elements like text or graphical features when you need to polish and adjust the final design.

If the align elements/grid size advice does not work on the misaligned
symbols/elements open same in symbol editor and realign the pin(s)
to the 50 units grid.
You may have to realign the pins using a smaller âunitsâ setting first
in symbol editor because the âsnap to gridâ is autoset to 50 units
and moving misaligned pins will realign them 50 units + pixel offset.
Zoom in to magnify and ensure a pin location is correct, then reset
the symbol editor to the 50 units default and use "Save Asâ to finish.
What is actually grid of 50 (units) ?
Please help where to find it in setting i.e. preference and other recommended its related values
View / Grid properties
Right click âBackground Gridâ Icon on top Left Hand side then Grid Properties.
The 50(units) is shown as 50 mils. This grid is used to place all pins of all symbols on Kicad.
Edit: as a further comment, this 50mil grid is a meaningless âactual sizeâ because when the page size or printing is changed the distance changes.
Realistically, this 50mil grid should be called the âsymbol placement & symbol movement gridâ. If any other grid is used with symbols, wires will no longer attach to pins.

To work with individual schematic components
âRight Button Clickâ on the component and select
Edit with Symbol Editor
In Symbol Editor âClick Onâ View Tab â> Grid Properties âŚ
Then follow instructions as above.
When I started to use KiCad I changed grid to position values and references. And of course it happened that I forgot to set it back to 50.
But someone told me to just switch grid off while moving texts.
In V5 I was doing it by using CTRL+SHIFT while moving text, but now (V7) CTRL alone is enough.

This, I try to never switch grids as its just too easy to forget to switch back

no such 50 mils, or 50 mm if itâs meant so
only there Current grid has dropdown values list of fraction of inch
User defined grid
ready to be set in pair of values
Fast switching grid

Should set 50 mm, if 50 mils itâs meant so, in âUser defined gridâ
then use it as current grid ?
This is the 50mils grid setting.
This setting should always be used when placing symbols on a Schematic so wires will conveniently attach.
This setting should also always be used when placing pins whilst creating symbols in the Symbol Editor
All other grid settings should be reserved for Graphics and Text.
no such 50 mils, on here
Immediately below the grid background button on the right hand side of your screen are the three âuse dimension buttonsâ (See my screen grab just above).
They are âinâ , âmilâ & âmmâ.
If you have âinâ (inch) selected, the correct grid will show: Grid:0.0500 in (1.2700mm)
If you have âmilâ (thousandths of inch) selected, the correct grid will show: Grid:50.00mils (1.2700mm)
If you have âmmâ (millimetres) selected, the correct grid will show: Grid: 1.2700mm (50.00mil)
These are all the same distance.
no such mils unit on v. 6.0.11
PLAN B
I suggest you make a separate schematic containing only the
unconnectable component(s) and add one known connectable component
such as a resistor or capacitor and then zip the schematic
and upload it to this post.
You could simply delete all other components in the project schematic
then add a good resistor or capacitor then âsave asâ
EXAMPLE
Filename: noconnect.kicad_sch
Zip Filename: noconnect.zip
Also zoom in to fit to objects and take a snapshot and post that too.
Then you wonât have to reveal your project design if it is confidential.
Someone may be able to help or even realign the parts in question
and re-upload to you.
