*** Update ***
After your post I had a new inspiration to see what I could do to make a decent print, Feel free to continue the work.
Firstly, switch your extrusion width to manual and adjust down to the the nozzle size. For a 0.4 nozzle, set it at 0.4. A 0.8 set it to 0.8
With the extrusion multiplier set to 1.00 print out a hollow box (not in vase mode). Zero top and bottom layers, one outline perimeter.
measure the thickness with accurate verniers. Mine was 0.45. Use the equation nozzle size / measured value. So for me it was 0.4/0.45=0.88.
That's your extrusion multiplier. If you were to reprint the box it should measure exactly the extrusion width value now.
Now, for my machine these values seem to be about right but may not be for yours. Retraction distance I have 2.2 and a -0.1 restart, lift 0.4, speed 30, coast 1.2, wipe 2mm.
Because I'm using ABS I'm around 245 deg C on the nozzle and for Layer tab 0.2 and the Speeds tab I've turned it way down to 25mm/s.
Hopefully I've given you the main changes but I made a near perfect Marvin with excellent resolution. Changing the speed back to 50 mm/s the print was good but no longer outstanding. With the results I got I actually think that I could eventually like this hotend.
Other research I've found indicates you can increase your speed if you decrease your layer height but I'm yet to confirm this.
Cheers,
