Hi can you help i try make command z_endstop_calibrat , give these info TESTZ Z=-1
19:30:55 !! Move out of range: 135.000 110.000 -0.783 [0.000]
19:30:55 $ TESTZ Z=-1
19:30:56 // Unknown command:“TESTZ”

Usually, if you try to drive to a sub-zero value (-1), it will lead to an error (“leftmost” position id X/Y/Z = (0,0,0)). It is very hard to understand your question in detail. Could you send some pictures? Did you walk through the klipper installation process?

HI this happen when i try config Z_ENDSTOP_CALIBRATE
I am not able to tune the nozzel to the table and when it starts to print it gets high and it does not print, only the filament comes out

6 
[stepper_z]
...
position_min: -2

Typically this should only be needed when using a probe. With regular endstops it should stay positive

OK i send my configuration for you check

Probe.cfg (485 Bytes)
printer.cfg (7.5 KB)

As previously indicated: When using a BLtouch then add a negative min position for z.

9

it’s telling me about the parameter stepper_Z possition_endstop: 0.0 change to -2 ?

a alredy change to -4 but still the same after that appears worning in kllipper probe [safe_z_home] , home_xy_position: 117,117 exed of range

Move out of range: 133.300 132.400 -4.700 [0.000]

Something seems very wrong with your printer. Have not seen the need to go to Z -4.7 or bigger with a probe before.
The negative value anyway is only used for the mesh and not for the z_offset. Typically a BLtouch is mounted around 2mm up from the nozzle and with its trigger length you would expect a z_offset of around 2mm.

Sorry no idea what could be wrong currently. Can you share a video of your calibration?

A damn, did not notice the obvious. You do not home with the BLtouch but with a regular endstop. Is this intentional?
If not then carfully work through BL-Touch - Klipper documentation, especially:

If the BL-Touch will be used to home the Z axis then set endstop_pin: probe:z_virtual_endstop and remove position_endstop in the [stepper_z] config section,
