I would drop the temp 5 degrees at a time and see. Heat is a problem printing Marvin.
You could reduce speed some but the default for PLA isn’t to bad. I think I was at around 20mm/sec but on a different printer.
You can also print 2-4 at a time which will help on heat.
Your .2 one isn’t bad. It may just be the filament also.
You could try backing off the extrusion multiplier just a little like no more than .05.
First thing maybe is do one of the test prints on the SD card and see how that goes and compare how the filament looks.
