Horrible Top Layer and a groove?

Just wrapped the guides and finished PA/EM so I decided to do a cal cube. This is an untouched Prusa slicer profile. Assuming the blob on top means more retraction? Why is the top quality so awful? Thoughts on the groove?

not enough cooling, what kind of filament and print settings? maybe there are other problems but the print is absolutely melted so can't really tell for sure

Its Polymaker PETG at 238 - My prusa loves it there, and I can bump up cooling but Polymaker it cool from 0-20% fan. I'll try again. I ran the belt tuner and they were decently out of alignent so I'll report back shortly

you are most likely print faster than on prusa, faster speed requires more cooling. temp looks fine :thumbsUp2:
