# Macros
|
|
|
|
## Hidden by the interface
|
|
|
|
All gcode_macros with the attribute `rename_existing` are hidden , because these are default Klipper Gcodes
|
|
and these should be implemented in KlipperScreen itself with buttons already.
|
|
[This is the same behaiviour of other UIs](https://docs.mainsail.xyz/overview/features/hide-macros-outputs-or-fans#macros-with-rename_existing)
|
|
|
|
[LOAD_FILAMENT and UNLOAD_FILAMENT are also hidden](#load_filament-unload_filament)
|
|
|
|
## Hide Macros
|
|
|
|
Macros can be completely hidden in the interface by prefixing the name with an underscore.
|
|
|
|
```ini
|
|
[gcode_macro MY_AWESOME_GCODE]
|
|
gcode:
|
|
_MY_HELPER_CODE
|
|
|
|
[gcode_macro _MY_HELPER_CODE]
|
|
gcode:
|
|
M300
|
|
```
|
|
|
|
`MY_AWESOME_GCODE` appears in your interface settings, but `_MY_HELPER_CODE` does not.
|
|
|
|
## Extrude Panel
|
|
|
|
### LOAD_FILAMENT / UNLOAD_FILAMENT
|
|
|
|
This macros are used in the Extrude panel `Load` and `Unload` buttons. and they will be hidden from the macros panel.
|
|
|
|
The selected speed in the panel is transferred as a parameter.
|
|
|
|
The following examples show how this can be used:
|
|
|
|
```ini
|
|
[gcode_macro LOAD_FILAMENT]
|
|
gcode:
|
|
{% set speed = params.SPEED|default(300) %}
|
|
{% set max_velocity = printer.configfile.settings['extruder'].max_extrude_only_velocity %}
|
|
SAVE_GCODE_STATE NAME=load_state
|
|
M300 # beep
|
|
G91
|
|
G92 E0
|
|
G1 E350 F{max_velocity * 60} # fast-load
|
|
G1 E25 F{speed} # purge
|
|
M300
|
|
M300
|
|
RESTORE_GCODE_STATE NAME=load_state
|
|
```
|
|
|
|
```ini
|
|
[gcode_macro UNLOAD_FILAMENT]
|
|
gcode:
|
|
{% set speed = params.SPEED|default(300) %}
|
|
{% set max_velocity = printer.configfile.settings['extruder'].max_extrude_only_velocity %}
|
|
SAVE_GCODE_STATE NAME=unload_state
|
|
G91
|
|
M300 # beep
|
|
G92 E0
|
|
G1 E25 F{speed} # purge
|
|
G1 E-420 F{max_velocity * 60} # fast-unload
|
|
M300
|
|
M300
|
|
RESTORE_GCODE_STATE NAME=unload_state
|
|
```
