Bad print results!

[AndThenSome09]

I tried to print an LED ring at all the default speeds which didnt turn out all that well, I think most of it was the speed but on some parts the insides of the edge dont meet. I'm just wondering if anyone has any experiance with these kind of results and what might help. ( I've drawn arrows to the places I am talking about)

Forgot to mention that recently I have had to take the nozzle off to clean a clog and I also added a PEEK fan. After I added the fan I did the PID auto tune for the hot end again.

Hard to say, looks like a number of things combined to cause this problem.

1) Possibly too low infill, when there are large gaps on the layer below, if you move too fast and don't have enough flow rate, it will break the filament and leave a hole.
2) Each perimeter line seems to be separate from the others, this suggests your extrusion width isn't properly calibrated. The slicer thinks the lines are thicker than they actually are.
3) Blobbing in various places suggests your retraction isn't calibrated quite to perfection. Lowering your temperature can reduce oozing, increasing your retraction speed and/or length may also cover it.

Thank you for that, I'll address all of the above in hopes of better prints!

Mine was doing something similar until i started printing off the sd card. It seems my pc couldn't keep up and i got a blob of plastic every time the printer stalled.
