Bed Leveling encounters the second point of MK3S measurement

I would like to compare Bed, I joined Prusa Mk3s Octoprint on RPI 3B, using the Prusa Leveling Guide plugin. The first (HOME) measures well, but when moving to the second measurement point, it swirls heavily into the pad and reports the Z axis error. No Octoprint is all right. I also edited settings according to Prusa Knowledge Base does not help. Anyone some idea? Thx
