Copper pour clearance from board edge

Layout
1

@eelik I’m looking for this ability today. (Using 8.0.4)

My board house can remove the 8mil(0.2mm) copper from the edge, but I’d like to just get it right on my end so they don’t have to clean up my copper pour/fill.

I would have hoped that either- this would apply to the edge as well…

Or that there would be a separate setting for ‘Edge Clearance’.

Maybe it exists and I have not turned over the right rock to discover it yet, but seems most intuitive to find it here…

Am I missing something obvious?
(I tried making the edge.cut line thicker, as stated above; but saw no change when looking at it via the 3D Viewer.)

I moved this to a new thread. The old one started back in 2016. KiCad was totally different back then

The function you are looking for is probably:

PCB Editor / File / Board Setup / Design Rules / Constraints / Copper to Edge Clearance.

This was set to a default of “zero” for some time, but later (maybe V8.0.2 or thereabouts) it was changed to a default of 0.5mm. If however your configuration directory was created before that time, the old preset of 0 keeps being used for new projects.

Edit: Cleanup after davidrsb split it off from the old thread.

It may also be worth noting that after that antediluvian version of KiCad (in the original thread) the developers have added Custom Rules, text based rule language with which it’s possible to set fine grained rules for edge clearance: different clearance for different items, areas etc. In most projects the one Constraint is enough, though.

Thanks @eelik, I have not explored that yet. Sounds interesting.

I’m putting a script together for a tutorial on the basics of v8 to try to help de-mystify KiCad a bit. I like how KiCad often offers many ways to get to the same thing (like 3 ways to start the Schematic Editor from the start page). Any chance the devs would consider adding a hot link to the Board Setup here titled something akin to ‘Set Copper to Edge Clearance in Board Setup’?

I’ve been using KiCad for years and have never looked there. Hoping there might be more ways to help others find settings that often feel like they are a bit hidden like Easter eggs.

Thanks again. Happy to keep learning. I really do love using KiCad.

Well, maybe. If you run DRC for example, there is also a direct link to the board setup to Edit violation severities

but I guess another way would be better. The Copper to Edge Clearance in the board setup is a hard absolute minimum. I guess it would be more logical if zones always kept their own clearance from Edge.Cuts. Maybe even add a separate copper to edge clearance for each zone.

Copper to Edge Clearance is also an incomplete name. The same clearance is also used for graphical items on the margin layer.
