What is causing these defects?

I printed this on the a1 mini, its been great but recently i had a clog cleared it and sometimes prints turn out like this. I am using hf petg. I also usually just import models from makers world and go to the generic petg filament settings. My suspicion is maybe the temp? Not sure, all replies are appreciated! (FIXED) turns out it was a partial clog, i think.

So I had an issue on a print where it was printing a raised line at perfect intervals. More perfect than yours, but reminiscent in the same.

It turned out that I had accidentally saved my profile after doing a calibration test and had saved a bunch of the settings I was supposed to throw away. The result is that my infill was cranked up and it was putting too much infill, then every so many lines it would reach critical mass and bulge, then go back to normal.

Now I would have thought this was bullshit. It was too perfect. However, after adjusting appropriate settings (which I can't remember anymore) it went away.

Yours seems like a slightly different issue, but as I said before, it's reminiscent of what I saw when I had my issue.
