Bed autoleveling randomly does not work

Hi folks,

The quality of my prints have increased substantially since adding autoleveling. However, maybe one in five prints will have the following issue:

Notice the pattern on the brim.

To be clear, when bed autoleveling works, the print comes out perfect.

I have done the M48 test and I get 50 microns stdev, so looks like my servo is working correctly.

I was thinking perhaps I have run into this issue?

Anyone else have a problem with bed autoleveling?

Bump.

I am having the same problem, im desperate to try and resolve, have you tried any of the solutions from the link? If i change my probing to 3 arbitrary points, my printer auto levels then goes off in the completely wrong direction...

Would there be a chance that the print fails depending on bed temperature settings? The bed could bend when getting to 120°C in order to print ABS but be fine when printing PLA at 60°C.

I would think that is certainly possible, check out this thread:

There is a good modification you can make to accurately tell how level & flat the bed is. I plan on doing this tonight.
