SOLVED: I have a CR10 V3 with this problem. After a couple days of troubleshooting, the thing that worked was to lower the bed on all 4 corners by 2 full turns (counter-clockwise) of the adjustment wheels. This could easily be fixed in the firmware if Creality is watching... Working the bed is a bit of a balancing act. Too low and the z-axis bottoms out. Too high the BLtouch doesn't work. Would really like to thank the developer that came out with the Bed Visualizer extension - extremely helpful.
