MoveTo raising object y axis?

So I'm trying to make an infinite thing where they touch something and it creates a new block. If they touch something it works and duplicates. I made sure there's exactly enough space between each object to that thousandths but there's someone object will be at the desired y-axis and some don't. their z-axis is what they should be with no more space allowed but not squished. Don't know why

player.Character:MoveTo(Vector3.new(player.Character.PrimaryPart.Position.X + Turn, player.Character.PrimaryPart.Position.Y, player.Character.PrimaryPart.Position.Z))
