## Extrude Panel
|
|
|
|
### LOAD_FILAMENT / UNLOAD_FILAMENT
|
|
Load and Unload Filament macros are 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
|
|
```
|
|
|
|
```
|
|
[gcode_macro UNLOAD_FILAMENT]
|
|
gcode:
|
|
{% set max_velocity = printer.configfile.settings['extruder'].max_extrude_only_velocity %}
|
|
G91
|
|
M300 # beep
|
|
G92 E0
|
|
G1 E{speed} F300 # purge
|
|
G1 E-420 F{max_velocity}
|
|
M300
|
|
M300
|
|
```
