Hello all. I'm new here, been printing for about a week now. I just got a Creality CR-10 Smart Pro. I'm having a problem when I'm trying to slice something that should definitely fit on my print bed but it says it doesn't fit. My bed is supposed to print 300 x 300 & the item is only 156 x 156. I can't find anything on YouTube or Creality's page. What could it be?...I'm sure it's just something simple but like I said, I'm a noob...tia
