Design Rules Checker discrepancies

I have been following along on a YT tutorial” Kicad 8 in 45 minutes]I used all the steps the host used, but when I ran the Design Rules Checker I got different results. He got 5 warnings, mainly silkscreen overlap and 0 errors. I got 1 error and 86 warnings. See pics:

Are the warnings about the Isolated copper fill some that can be ignored?
Is the error critical? I’m not sure what “Thermal relief connection to zone incomplete” means.
I’m not sure why I didn’t get the same results as on the tutorial.

Maybe you got the isolatiom of the filled zone too big. Try it with 0.25 or 0.2 mm.

Is this where you change it?

I changed all the numbers to .25, and it got more errors and warnings.
Maybe I took the wrong path, the is no dialog of isolation for the filled zone?

It’s the Electrical Properties / Clearance in the center of your screenshot. After you’ve exited this window, you also have to press b to re-calculate internal zone geometry (although that can be set to automatic I think).

@nickmBY If you give directions, please use the same terminology as KiCad uses, this avoids a lot of confusion by beginners who don’t know the terminology.

I got rid of all the warnings by changing the properties t the bottom right corner t remove Island and worked up to 1000 sq. MM.

I worked my way back to 850 sq. mm.

Now I have just this error.

The yellow arrow is pointing at it.

Yup, and you understand what it means ? that connection to an isolated “island” effectively does nothing much . . . is that OK for you ? as the designer it’s your job to decide if this is OK or not.

Thank you! As an electrical engineer my examination was telling me the this would have no issue electrically. I couldn’t wrap my head around why this was labeled as an error. Your answer is perfect.
I guess we can ignore some errors, based on an educated examination of the issue. Does the pcb manufacturers catch these errors when uploading the gerber files? I have yet to order any, so I wasn’t sure. Thanks to all of you for your support. :computer:

Not that kind of “error” some will catch clearance issues or copper tracks/floods being too thin, some do a better job at this than others.

They don’t know the design intent of your PCB so there is only so much they can know.

I would be more concerned with this:

Did you use an autorouter? Because that sure is ugly…

yep, used an autrouter. Good catch. can it be fixed? or does it all have to be done over manually?

You should be able to touch it up in pcbnew.
