I don’t have this problem. I have a precision piezo Orion probe. My probe is my nozzle.
How do you handle residual filament on the nozzle from previous prints? Or if you heat it up to get to nozzle itself to touch the bed, do you get dabs of plastic distributed around your bed?
I preheat to 170°c. That allows the filament to be soft enough to be cleaned (with tweezers or a brush, it peels off in one piece most of the time) without oozing. Then I do a 10mm retract before probing.
That's smart!
