hi, welcome,

from what i have learnt, 230c at nozzle is way to hot for PLA,

try
nozzle = 195 (even thats to hot but works for me)
infill = 10% - 15%
shells = 2
build plate at 65c
movement speed 40
travel speed at 70

these will give you some quality results, except on hugh overhangs, still trying to figure that one out, but i did print an iphone 5 case last night and came out perfect with those settings
