Extruder Reference Information

This page contains reference parameters for common extruders, primarily used to quickly establish initial configurations.

Usage Notes
  • The rotation_distance, gear_ratio, and pressure_advance below are for reference only; actual machines require recalibration.
  • It is recommended to recalibrate the extruder steps after replacing the extruder, motor, gears, filament path, or nozzle.
  • pressure_advance is related to the hotend, filament, speed, and slicer parameters and cannot be directly copied.

## Controlling One Hotend with Dual Heater Outputs

If two heater outputs are used to jointly control the heating element, use `[multi_pin]` to merge the heater pins, then change `heater_pin` to `multi_pin:extrude_heater`.

```cfg title="printer.cfg"
[multi_pin extrude_heater]
pins: PA1,PA2

[extruder]
heater_pin: multi_pin:extrude_heater
