quick tips, without much explanation


## Hide macros, outputs or fans
As you probably already noticed, you can show and hide the gcode macros in the interface settings,
but you can also hide gcode macros by prefixing the name with an underscore.

```py
[gcode_macro MY_AWESOME_GCODE]
gcode:
    _MY_HELPER_CODE
[gcode_macro _MY_HELPER_CODE]
gcode:
    M300
```

MY_AWESOME_GCODE appears in your interface settings, _MY_HELPER_CODE not.

Another example:

Lets hide a temperature_fan:

```py
[temperature_fan fan1]
[temperature_fan _fan2]
```

fan1 will show in the interface, but _fan2 will be hidden.

## Layer Progress

Accurate layer progress as a message below the status:

PrusaSlicer/SuperSlicer > Printer Settings > Custom Gcode > After layer change Gcode

`M117 Layer {layer_num+1}/[total_layer_count] : {filament_settings_id[0]}`

Accurate layer progress in the secondary screen of the printing panel:

The layer number in the secondary screen of the printing panelis calculated according to object height and provided layer height.
It will be innacurate when using variable layer height, but can be fixed by providing klipper with the correct data.

PrusaSlicer/SuperSlicer:

Printer Settings > Custom Gcode > Start Gcode

`SET_PRINT_STATS_INFO TOTAL_LAYER=[total_layer_count]`

Printer Settings > Custom Gcode > After layer change Gcode

`SET_PRINT_STATS_INFO CURRENT_LAYER={layer_num + 1}`
