This page lists all configuration options for the Extruder module.
For more detailed information and examples, see the Extruder guide.
| Parameter | Default | Description |
|---|---|---|
extruder.module_name.enable |
true | Whether to activate the extruder module at all. All configuration is ignored if false. Each time an extruder.module_name.enable line is encountered, an extruder module with the name «module_name» will be created. |
extruder.module_name.steps_per_mm |
140 | Steps/millimetre for the extruder stepper motor. This is the number of steps to move one millimetre of filament. Learn more |
extruder.module_name.filament_diameter |
1.74 | Filament diameter, in millimetres, used for volumetric extrusion control. Learn more |
extruder.module_name.default_feed_rate |
600 | Default rate in millimetres/minute for moves where only the extruder moves. This is only used if you have never provided a feedrate via the F parameter. Once you specify a F parameter, it will be used as the Extruder feed rate until you reset the board. |
extruder.module_name.acceleration |
500 | Acceleration for the extruder stepper motor, in millimetres/second/second |
extruder.module_name.max_speed |
50 | Maximum allowable speed for the extruder stepper motor, in millimetres/second |
extruder.module_name.step_pin |
2.3 |
Pin for extruder stepper motor driver’s step signal |
extruder.module_name.dir_pin |
0.22 |
Pin for extruder stepper motor driver’s direction signal |
extruder.module_name.en_pin |
0.21 |
Pin for extruder stepper motor driver’s enable signal |
extruder.module_name.x_offset |
0 | Extruder offset from origin in millimetres for the X axis. ONLY used when you have multiple extruders to specify the offset from each extruder to the first one. |
extruder.module_name.y_offset |
0 | Extruder offset from origin in millimetres for the Y axis. ONLY used for multiple extruders |
extruder.module_name.z_offset |
0 | Extruder offset from origin in millimetres for the Z axis. ONLY used for multiple extruders |
extruder.module_name.retract_length |
3 | Retract length in millimetres. Retract is a retractation of the filament called using the G10 G-code. It is recovered (reverted) using the G11 G-code. Learn more about retractation |
extruder.module_name.retract_feedrate |
45 | Retract feed-rate (filament speed) in millimetres/second |
extruder.module_name.retract_recover_length |
0 | Additional length when recovering (if you retract by 1mm, you will be recovering by 1mm plus this value) |
extruder.module_name.retract_recover_feedrate |
8 | Recovery feed-rate in millimetres/second (should be less than retract feedrate) |
extruder.module_name.retract_zlift_length |
0 | Z-lift on retract in millimeters, set to 0 if you want to disable retraction Z-lift. Z-lift is a small increase in the Z axis position when retracting. |
extruder.module_name.retract_zlift_feedrate |
6000 | Z-lift feed-rate in millimetres/minute (Note: mm/min NOT mm/sec) |
delta_current |
1.5 | First extruder stepper motor driver (M4) current in Amperes |
epsilon_current |
1.5 | Second extruder stepper motor driver (M5) current in Amperes |
