Why the circle drawed by "G2 X390 Y-280 I5 J0" not round?

find Xpos_fb's waveform lags Xpos's waveform 50ms, but y axis hasn't it, what's the reason of this problem generally?.

As I said before, the most likely cause of the ~50 ms delay and waveform distortion is the X drive drive tuning or setup, that is, the Y axis drive is closely following LinuxCNCs commanded position, the X drive axis is not.
