I apologize for the poor quality of this photo. Unfortunately it was the best I could get with my camera and lighting available. The print is really melty looking at the top and what should be a square hole in the middle is misshapen. I’ve tried adjusting the speed and minimum layer time to prevent melting but that has only gotten me this far. What other things can I do to improve this print quality. I’m using all stock parts on the K8400.
You didn’t show us the size of your piece. Small pieces are more tricky to print.
If you’re using the stock parameters, modify this :
Temperature : 190-195 (PLA) - 220 (ABS)
Flow 75%
Retraction 3 mm - 150 mm/s
And if your piece is small activate the “Cool head lift”.

Raby thanks for your response. I’m still pretty new at this so I wasn’t sure what information was really important. The grid I took the photo on is 1". I did that for scale but then forgot to mention it. The retraction you mentioned is that 3mm retraction distance and 150 mm/s retraction speed? I’ll try that tonight. I want to print some rocket nose cones. They aren’t small parts but do taper off pretty small at the end.

I guess that the heat gets to high on the last layers, thats because to the heatreflection from your hotend continues to heat everything underneath and on a very little spot. So the heat cant get away and thats why it looks melted.
Try to print two of them so one could cool down a little while the heat moves to the opponent position. Most times that makes the trick from me.
