@exlink No need to up the bed temperature, just the hotend temperature to help the plastic to melt faster. If you run a .8mm line width, put your slicer at 4mm / 5 lines thick wall.

@exlink The Creality hotends cannot melt near enough plastic to put a 1.0mm nozzle to good use, it has too short of a melt zone in combination with the PTFE lining that gives it really bad thermal performance for high-flow scenarios. It can only do about 10mm3/sec with a 0.8mm nozzle, and this is pushing it. I would suggest you to go down to a 0.8mm nozzle, raise the temperature for printing pla to about 240C, with 0.8mm line width and a 0.25mm layer height, at 40mm/s and see if that works out for you. It cannot be easily stacked with these settings. Larger nozzles (which makes it print faster) also makes single extrusion stacking harder.
