Observation on too great a difference while autoleveling

· Observation on too great a difference while autoleveling
I noticed that if you have adjusted the bed height manually too high with the thumb screws the spring pressure isn't enough to give the right feed back(?) for auto-leveling. We had an issue where every print was giving the "Difference detected too great..." error until we lowered the plate significantly with the manual thumb screws and re-leveled the build plate.
I am too new to give a definitive answer. But I find it usually has to do with either gunk under the nozzles (cleaned it and re-ran active leveling successfully) or when changing the glass plates, it can get knocked a bit. It is a springy board and that is why I got the extra glass plates. I can get one off easily, put on another and do a new active level. I have noticed that it is still good to do a manual level often as it will drift out of alignment or start to skew.
Also, as glass is a difficult substance to manufacture with hyper accurate results, changing build plates should be manually leveled often anyway. I always do an active level after I manually level it. Mostly to check myself or get rid of any skewing that I did not notice.
And, I have read that there are some glass plates that are not perfectly level too.
I do tend to keep my thumbscrews close to full extension with just a little back off into a comfortable range of motion. Too tight in one direction or the other and it starts to get hard to turn.
