A20M Auto Bed Leveling Help

[Meierme176]

I just recently purchased the Geeetech A20M and their 3D touch auto leveling sensor.

I have followed the steps in this video:
https://www.youtube.com/watch?v=deq10MaxQBw
because the processes in this video:
https://www.youtube.com/watch?v=o1QKSgnk_ig
are outdated.

I have successfully updated the firmware but before it succeeds Arduino shows these messages:

Code: Select all

Build options changed, rebuilding all

                 from sketch\configuration_store.cpp:190:

Sketch uses 165624 bytes (65%) of program storage space. Maximum is 253952 bytes.
Global variables use 6058 bytes (73%) of dynamic memory, leaving 2134 bytes for local variables. Maximum is 8192 bytes.

When I make it "Auto Home" It does it successfully, but when I hit "bed leveling" it will do the center, front left, and front middle correctly however when it gets to the front right it lowers the extruder to where it almost touches the build plate and when it gets to the middle right point it lowers way too far and I get a "Probing Failed" error message.

My Marlin version is 1.1.8 and the Arduino version is 1.8.5

I do not have code that resembles that under configuration.h

Meierme176, did you ever find a fix for your problem?

I am experiencing the exact same issue.
