First layer prints too thin causing gaps everywhere
From the picture it is clearly seen that the filament is not flattened properly. This implies that your nozzle bed distance is too large. Try decreasing the gap by leveling the bed at temperature and have a piece of "A4" or "Letter" print paper between the nozzle and bed have a little friction when pulled.

Also reduce the temperature, 230&nbsp;&deg;C is too hot for PLA (unless your printer temperature is way off, but that is not very likely), try 200&nbsp;&deg;C.

Another thing that you could check is if the extruded length is exactly what is instructed to be extruded; i.e. calibrate the extruder.
