After some intensive cleaning, PID tuning, and final tightening of the nozzle, my newly installed E3D v6 hotend seems to be playing nicely with the Monoprice mini. Been printing a lot of test objects in eSun gray PLA+ filament. Currently printing a 3D Benchy as a torture test.
And yeah, got a way to go yet. Looks like oozing on the overhangs.
I think you should add a part cooling fan.
Looks like you need cooling. Watch as the bow is printing. You’ll almost certainly see it curling up, and the nozzle pushing it back down as it puts down the next layer.
@Jon_Stern yeah, that’s exactly what I was seeing. Time to get creative…

Here’s what I did to boost my part cooling. I bought two of these USB fans:
And two of these power outlets with USB ports: https://www.amazon.com/gp/product/B00YLRWYVQ/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
I stuck the outlets on either side to the printer frame using strong double-sided adhesive tape, plugged in the USB fans, and aimed them across the bed.
[I also, plugged in two similarly flexible USB lamps, but after a month of running those 24/7 they dimmed to virtually nothing.]
It improved my bench overhangs enormously.
