## Touch Mode First Print

You might notice your z-offset is a little wrong, this is hugely dependent on too many things, however its simple to fix. Just use the video below as an example.\
\
`scanner_touch_z_offset` is the distance between nozzle and bed after a `CARTOGRAPHER_TOUCH`

Default `scanner_touch_z_offset` is 0.05

## Scan Mode First Print

Tweaking the Z offset is done slightly differently with Cartographer compared to using a standard probe, for example, with Cartographer you can't use \`PROBE\_CALIBRATE\` to fine tune the offset, as that will reset the 0 point, so you need to tweak it manually.

#### Klipper Screen <a href="#klipper-screen" id="klipper-screen"></a>

Unfortunatly, due to the way Cartographer works, we advise against doing this via Klipper Screen, as we have seen some sporadic outputs.

#### Mainsail <a href="#mainsail" id="mainsail"></a>

If you are using more than just the `default` cartographer model, you will have to load which ever model you want to make the adjustment too, you do this using the following command, replacing the NAME=hot, with what ever model you are selecting i.e. NAME=sparklybed

`CARTOGRAPHER_MODEL_SELECT NAME=hot`

You can adjust your Z Offset in Mainsail using the Z-Offset section of the Toolhead pane.

after making the neccessary adjustments press the `SAVE` button

And then press `SAVE CONFIG`

Once complete, your Z offset change should be evident under model\_offset: under the specific model which was loaded. NOTE - You will have to adjust the offset for each model you use.

## Setting Z Offset

Before modifying your Z Offset, make sure that you have set your Z position to 0, to do this you can run the following command.&#x20;

```gcode
G1 Z0 F1500
```

Once you have done all of the above, it is worth re-calibrating the Z-Offset. This can be done in Mainsail or Fluidd using the graphical interface. \
\
OR you can use G-Code in the window to console to do so

```gcode
SET_GCODE_OFFSET Z_ADJUST=+0.01 MOVE=1
SET_GCODE_OFFSET Z_ADJUST=-0.01 MOVE=1
```

Once the offset has been perfectly calibrated apply that offset using the following command

```gcode
Z_OFFSET_APPLY_PROBE
```

And now save your config.

This is the end of the setup and calibration process.&#x20;
