At the beginning, let's imagining all the value of X Y and Z axis are Positive number, which will definitely make things easier to understand.
1. When i done a first testing model, the E 2 shifts leftward, it's 1 mm after measured.
So i minus 1 mm to the original value:365.4 (364.4),and the model be printed this way, which is absolutely wrong.
2. And this is the result after i add 1 mm to 365.4(366.4), just works.
However, it's still something that seems to be wrong, there still a visible gap (about 0.5 mm)between Cut 1 and Cut 2.
So I decide to Add 0.5 mm for Z axis, but the result:
3. Finally, i minus 0.5, which means set the value as 0, since the original value is 0.5, and it just perfect.
