Z-Offset Troubles, Always getting a different Value

Hi everyone, this is my first post trying to get help.

I’m having issues with my z-offset, every time i make the PROBE_CALIBRATE comand, gives me different values.

I was printing with no issues, and using in every print the same Z-Offset, suddenly after changing the filament and starting other print, i began to have troubles with the offset.

then, I started to babysteping z-offset while printing, but every time a get a offset, the next print need the offset to be far from the bed like .050 or .1

now i have the offset set to -.141

every probe calibration. this value start to raise.

Now, I try to use BED_MESH_CALIBRATE, but suddenly the printer stops, sending in the screen “Key 2060” here’s the Log

{“code”:“key60”, “msg”:“Internal error on command:BED_MESH_CALIBRATE”, “values”: [“BED_MESH_CALIBRATE”]}
