Voron 2.4 + Klicky Probe : nozzle too far from plate when printing

Hello,
It happened after a nozzle change but maybe not related
I've been searching in vain since yesterday. Please help.

I manage to pass the BASE_CALIBRATE_Z by modifying the position_endstop and switch_offset, but when printing starts, the nozzle is much too far from the plate (2mm ...)

BASE_CALIBRATE_Z: bed_probe=8.349 - (switch=6.413 - nozzle=1.698 + switch_offset=2.800) --> new_offset=0.834000

I'm lost here

hi

clear Z offzet after use G32,PROBE_CALIBRATE and bed_mesh_calibrate, then save the bed_mesh, lower the nozzle to bed and with a sheet of paper calibrate the Z offzet, save and test print.
