When I change my Infill/External Infill Pattern to 'Concentric', I'm getting an odd pattern as shown in the attached image that I've drawn around. Outside of that pattern, its concentric as it should be. Does anyone know what might be causing this?

Thanks

Remove the text and it should go away. I almost never use concentric due to side effects like this with detailed geometry. Your best bet is to stick to rectilinear.

Yeah, it's doing exactly what it's supposed to - concentric lines to the boarders - in this case it's concentric to your lettering.

I see. Thanks!
