If you are using slicer, you want to print with 0% infill, 0 top layers, and 1 parimiter. Then you can measure the wall thickness to see if you are over extruding, X dimensions, Y dimensions and Z dimensions. From that you can determine allot, like how much you want to adjust flow rate, X steps, Y steps, Z steps.
IMO you shouldn’t have to crank the temp up so high and it might cause you other problems. I had a piece crystalize and clog my print head. Are you using blue painter’s tape to on the bed? If so, consider swabbing with some rubbing alcohol as well. I’m printing @ 195-200 and at times was at 185. Of course it can vary with different brands of filament, but I need to use a putty knife to get things free from the bed using 3M’s tape.
Yeah, I’m still in heavy tweaking mode, but with alcohol rubbed blue tape and 190 degrees, the printhead was just pushing plastic around in a big gooey mess.
I’ve upped the print size and the current 3cm cube with infill is looking awesome…not perfect, but very very good for print #5.
