      Occasionally I end up with one or two "outlier" points in my bed leveling mesh. This can be due to hitting a small piece of debris on the bed, finding a gap in blue tape, or being right at an axis limit and having some chassis contact deflection.

      I was think that a useful way to avoid compensating for an erroneous point would be to either do a TRIMMEAN, where you toss out anything in the upper and lower percentage away from the mean.

      Or, you could go another direction and have an allowable point-to-point delta, which when exceeded, the point gets thrown out. This could be harder, because you have to decide which point stays and which goes. You could just keep the one closest to the mean I suppose.

      I know that there are ways to avoid these points in the first place, but 'ish happens, right?

      Thoughts?

        Sounds like a good idea.

        In the meantime you can edit those points in the CSV file as needed. I've done that in the past when it was just one point that was way off.
