Z wobble test

Hi guys, I made this test model to test my bambu lab printer Z axis. The length of the raw model is 240mm, almost reach the max of z travel. I upload print file for X, and P series, also for A1 mini. Use filament color that shows layer line, don't use those matte or special blend filament. Instruction: So you will observe at the front to see any obvious uneven lay line: Mine looks good. Then, in 45 degree angle: Mine looks good tho. If your's look like this: It is not good. (pic source: theprusa
