This document provides comprehensive assembly instructions and operational guidelines for the Sailfin Extruder + V6 Kingroon KP3S Pro, a modification designed to enhance 3D printing capabilities. The modification focuses on improving the extrusion system and integrating various optional sensors and components for advanced functionality.

Function Description

The Sailfin Extruder + V6 Kingroon KP3S Pro is an upgraded extrusion system for 3D printers, specifically designed for the Kingroon KP3S Pro. Its primary function is to provide a more reliable and precise filament extrusion, which is crucial for high-quality 3D prints. The V6 hotend integration ensures consistent heating and melting of filament, while the Sailfin extruder mechanism is engineered for efficient filament feeding. This system aims to improve print accuracy, reduce common printing issues like under-extrusion or inconsistent layers, and offer greater flexibility in material compatibility.

The core components include a Sailfin extruder body, a V6 hotend, and various fans for cooling. The extruder is responsible for pushing the filament through the hotend, where it is melted and then extruded through the nozzle. The V6 hotend is known for its all-metal design, which allows for printing with a wider range of materials, especially those requiring higher temperatures. Cooling is managed by a layer fan, which cools the freshly extruded plastic, and a hotend fan, which prevents heat creep into the cold end of the hotend, ensuring smooth filament movement.

Optional enhancements include the integration of an inductive sensor or a 3DTouch sensor for automatic bed leveling. These sensors detect the print bed's surface irregularities and adjust the Z-axis accordingly, leading to better first-layer adhesion and overall print quality. Another optional component is the Fysetc portable input shaper, which helps to reduce vibrations and ringing artifacts in prints, further improving surface finish.

Usage Features

The Sailfin Extruder + V6 Kingroon KP3S Pro is designed for users who want to upgrade their Kingroon KP3S Pro printer for improved performance and reliability. The assembly process involves integrating 3D printed parts with commercial components. Users will need to print several custom parts, including the Front_Mirror.stl, Lever_Mirror.stl, Mid_Mirror.stl, and Rear_Mirror.slt files, which are essential for the extruder's structure. These parts are designed to be printed with a 0.4 nozzle, with an infill of 25-30% for optimal strength without supports. Special attention is given to certain holes that may be covered during printing, requiring a small drill (3-3.2 mm) to clear them for proper fitment.

The assembly begins with attaching the back case to the printer, followed by the integration of the V6 hotend and the PTFE Capricorn tube. The front case and the Sailfin extruder mechanism are then assembled. Proper orientation of the hotend block is crucial, as indicated in the assembly diagrams. The layer fan and hotend fan are installed next, ensuring adequate cooling for both the printed part and the hotend itself.

Wiring is a critical step, involving connecting the layer fan, stepper motor, hotend fan, heater cartridge, and thermistor to the mainboard. The document provides clear color-coded instructions for wiring these components. For instance, green indicates layer fan wiring, blue for stepper motor and hotend fan, and red for heater cartridge and thermistor. Cable ties are recommended for securing the wiring, and an optional cable sleeve can be used for a cleaner look.

For users opting for automatic bed leveling, the inductive sensor or 3DTouch sensor can be integrated. The inductive sensor requires specific wiring to the mainboard's Z_min or Z_max ports, with S for signal, G for ground, and 5V for positive. Similarly, the 3DTouch sensor also connects to specific pins on the mainboard, with instructions provided for identifying signal, ground, and 5V lines, which may vary by manufacturer. Offset values for both sensors (X=-18.40 Y=-30.5 for inductive, X=-14.6 Y=-34.2 for 3DTouch) are provided to ensure accurate bed leveling calibration.

Firmware adjustments are necessary after hardware installation. Users will need to configure the sensor type for the hotend in either Marlin or Klipper firmware. For Marlin, this involves setting TEMP_SENSOR_0 to 5 in configuration.h. For Klipper, sensor_type: ATC Semitec 104GT-2 is specified. Additionally, the steps per unit or rotation distance for the extruder must be adjusted. In Marlin, DEFAULT_AXIS_STEPS_PER_UNIT needs to be set, with a note about adjusting drivers to UART mode for 16 microsteps. For Klipper, rotation_distance, gear_ratio, microsteps, and other extruder parameters are defined. Finally, the hotend fan pin needs to be configured in the firmware, typically E0_AUTO_FAN_PIN PB0 for Marlin and pin: PB0 for Klipper.

Maintenance Features

Maintaining the Sailfin Extruder + V6 Kingroon KP3S Pro involves ensuring all components are properly secured and functioning. Regular checks of the wiring connections are important to prevent disconnections or shorts, which could lead to malfunctions. The use of cable ties helps in organizing and securing the wiring, reducing the risk of damage from movement.

The 3D printed parts, while robust, may require occasional inspection for wear and tear, especially if printing with abrasive filaments or at high temperatures. If any printed part shows signs of damage or deformation, it can be easily reprinted using the provided STL files.

The hotend and nozzle are critical components that require periodic cleaning or replacement. Filament residue can build up in the hotend, leading to clogs or inconsistent extrusion. Users should follow standard hotend maintenance procedures, such as cold pulls or disassembling the hotend for cleaning, as needed. The V6 hotend's design generally facilitates easier maintenance compared to some other hotend types.

Fans are essential for cooling and should be checked for proper operation. Dust accumulation on fan blades can reduce their efficiency, so occasional cleaning is recommended. If a fan becomes noisy or stops working, it should be replaced promptly to prevent heat creep or inadequate part cooling, which can negatively impact print quality.

The inductive and 3DTouch sensors, if installed, should be checked for proper calibration periodically. Environmental factors or printer movements can sometimes affect sensor accuracy, necessitating recalibration to ensure consistent bed leveling. The offset values provided in the manual serve as a baseline, but fine-tuning may be required based on individual printer setups and preferences.

Firmware settings, once configured, generally remain stable. However, if new issues arise or if the printer's behavior changes, reviewing the firmware settings for the extruder, hotend, and sensors can help diagnose problems. Keeping the firmware updated to the latest stable version can also provide performance improvements and bug fixes.

Overall, the Sailfin Extruder + V6 Kingroon KP3S Pro is designed with user-friendly assembly and maintenance in mind, allowing users to effectively upgrade and maintain their 3D printer for enhanced performance.
