# Supported Macros
Klipperscreen supports gcode_macros in various panels.
## Extrude Panel
### LOAD_FILAMENT / UNLOAD_FILAMENT
Load and Unload Filament macro is used in the Extrude-Panel if it is available.
The selected speed is transferred to this macro.
The following example macros show how this can be used in the macro.
```
[gcode_macro LOAD_FILAMENT]
gcode:
{% set speed = params.SPEED|default(500) %}
G91
G1 E50 F{speed}
G1 E50 F{speed}
G92
```
```
[gcode_macro UNLOAD_FILAMENT]
gcode:
{% set speed = params.SPEED|default(500) %}
G91
G1 E-50 F{speed}
G1 E-50 F{speed}
G92
```
this could be interesting to tweak the purge speed, this would be one Example Macro from alfrix:
```
[gcode_macro LOAD_FILAMENT]
gcode:
{% set speed = params.SPEED|default(300) %}
{% set max_velocity = printer.configfile.settings['extruder'].max_extrude_only_velocity %}
M300 # beep
G91
G92 E0
G1 E350 F{max_velocity}
G1 E25 F{speed} #purge
M300
M300
```
