This might be a case of placebo effect, but it’s worth a shot.
I noticed today that my GF kept needing to calibrate and was having trouble figuring out where it was. And then it struck me that there was a lot of powdery crud on the top of the head from all the stuff I’ve been cutting. And that some of it might be complicating the GF logo that the camera recognizes to do the homing thing. So I took five seconds and wiped it off. Performance seems to be better.
Or maybe I just feel better about having done something.
