** 1. I recommend setting your bed to 430x430 to get the max build volume of your machine and it will also center all parts you slice in the future by default they are shifted in real life compared to the slicer software showing they are centered. 

    2. Another way to remedy this is to uncheck origan at center if your slicer if the slicer has this option available to you.
