BDSensor installed and *almost" perfect. M102-6 runs OK, M102-5 gives good results, with initial reading = 230 and next reading = 242. Saved settings. But when printing, the nozzle is too high off the bed. I have to baby step it down bu .5mm in order to get good bed adhesion. I've been using it like this for some weeks, and I'm OK with it, but two questions: (1) WHY is there this discrepncy? (2) Why does setting z_adjust: 0.5 (in printer.cfg under the BDSensor section) not work. I STILL have to set baby steps to -0.5 mm

in this case, we usually fix this by calibration again. and there is a limite range for the z_adjust(-0.3 to 0.3mm)
