bltouch z offset

The only thing that requires a calibration is the Z-probe offset. 1. M851 followed by your offset you noted down in the last step, in the photo above the command would be M851 Z0.00 but yours will look more like M851 Z-0.90. the pin while retracted should be 2mm +/- .5mm from the bed with the nozzel touching the bed. The BLTouch is very accurate and consistent after the initial setup but there are times when you I am also using 1.1.x bugfix with my bltouch no issues. I am using Marlin bufix-1.1.x and recently upgraded from a capacitive sensor to an original BLTouch from Antclabs. My leveling BLTouch is 37mm to the right of the nozzle, and 2mm behind it, so I would put the following settings. Check the Z position on the printer screen, and subtract another 0.1 from this value to account for the thickness of the paper. The next step was to disable the software endstops und lower the nozzle to its final position (using the paper test). Marlin told me a Z offset of -1.09. -1.4 in this example Control > Store memory Fine tuning – after initial setup. Check that the Z probe reading in DWC is correct (about 537 for the Mini Differential IR probe, and about 1000 for most other types). And if you do touch it, be very gentle, in order to not bend or push anything. Regolazione Z Offset Una calibrazione necessaria quando si installa il BLtouch o una sonda induttiva è comunque utilizzata sempre quando c’è una discrepanza tra dove l’ugello è e dove dovrebbe essere.
