Increasing the temperature did fix it for the test print but not the much larger print. Will try again with the suggestions given.

So I increased the temperature by 10, that fixed the issue. Thanks.

More top layers and/or more infill.

Cheerio,

Almost like the head is too close and damaging what has just been printed. 0.25 nozzle PLA
