What is this?

Somehow this ended up on my PCB view. I have no idea what it is. I can’t select it, so I don’t know how to delete it. What is it?

TIA,
Ian

It certainly is a origin of something (grid, drill/place file origin, …).
If you set that origin to 0,0 the mark will disappear, I think.

The existing marks can depend on KiCad version. I have 7.0.11. Don’t know if in V8 there are some new origings or not, and don’t know what is your version.

Coordinate system, grid and origins in the PCB Editor

Introduction This article describes version 6.0. Many details were applicable to v5.1, and the coordinate system and origins haven’t changed as of v8.0. KiCad is a CAD system with 2D data which needs coordinates to mark locations of items. In theory it’s possible to have a CAD system which relies completely on constraints, not coordinates, but KiCad can’t be like that. There must be an internal coordinate system and all explicitly defined locations must fit to that system. The layout editor ha…

A bit outdated but essentially correct; however, it doesn’t answer the question. It’s the Grid origin and as Piotr said, you can set it to 0,0 (for example from Edit → Grid Origin menu) and it disappears.

I’m on 8.0.0. There’s no Edit → Grid Origin menu item for me.

Thanks to all though. At least I know what it is. I still wish I knew how it came about. I’m just a little bit of a perfectionist.

I really wish KiCad had the thing where the help menu would let you search for menu items, but I don’t want to complain, because I know the answer is likely to be “Be the change you want to see in the open-source app.”

Update to 8.0.1 and you’ll see it.

Yup. That did it! Thanks.
