Thanks Yeti, Found something new: for same image (256x256px), same tip radius, (50nm), non-contact it does set to the 20x20px size but the height of the tip changes with rotation. After I model each tip I use the set minimum to zero data process and measure the height of the tip 0deg: 61.5 nm 45deg: 66.9 nm 90deg: 61.5 nm 135deg: 63 nm 180deg: 64.3 nm 225deg: 59.1 nm 270deg: 64.2 nm 315deg: 63 nm
I think about it I can't imagine a way in which the height would be the same. I can't even imagine how you turn the tip in the first place. I guess it's a small tip and rounding errors are more drastic?
