As for the Z-probe, my current strategy is to traverse down to 100mm from expected bed and do a G30, that should cover any combination of tool and print bed so to say. However the M581 tap-test seem ingenious. Thank you!
But, using blowers instead of the BerdAir is one of my desired outcomes here, as I feel the berd is (compared to noise level) not the best way for a high flow hot end. I may be completely wrong here?
