BLTouch...what does it really do?
I have an Ender 3 Pro, BLTouch with correct FW. Every print does the 9 point touch. I still need to level the bed regularly. What is the expected behavior of this actual leveling? If I do not have the system 100% perfect, it doesn't print anyway. I'm just not sure what BLTouch is doing, or if I have it misconfigured.
