1.1.x_bugfix Leveling issues (2 replies)

Hi-

I am having trouble with bilinear bed leveling with the 1.1.x bugfix release. I can not determine if its the sensor being flakey or if its the firmware.

Here is a video of Autohoming and G29 leveling. The bed does not properly retract/advance when its probing points 6, 7 & 8.

Here is a copy of my logfile with debug turned on. At around line 2590 is where i am determining the probe trigger value. The Bilinear grid is reported at line 3130.

2018-06-01 00:13:14,238 - Recv: corrected Z:4.04

I leveled the bed corners as best I could before I autoleveled, so I really don't believe the mapping or corrected Z of 4.04mm.

Is the probe being flaky or is it Marlin?

Thanks
