speeding up print

I am printing a 6"x6"x2.5" PLA box, with some internal parts. I’m using a TAZ 6 with 0.5 mm nozzle. The print time is quite long if I use my usual settings (22 hours), but if I set the layer depth to 0.15 mm, and the nozzle extrusion width to 0.7, I get that time down to 12 hours. There is no fine detail in this box, and the smallest feature is 2 mm. Is there any reason not to use the relaxed settings to speed this up?

Thanks in advance for any insights.

Well you have a 0.5mm nozzle. If you set it to 0.7mm it will leave .1mm of empty space on both sides of every single extrusion. It will not look great. Far better to set the layer height to 0.32 to 0.42mm instead.
