1Description

Mellow HeatCore 4 UHF ALPS Hotend is a compact, high-performance, high flow, high-speed front-end solution for Voron series 3D printers. It supports stable extrusion at speeds exceeding 40mm ³/s and high-temperature printing at 400 ℃. We are equipped with a complete upgrade kit and replacement parts here, with multiple optional kits to meet your needs for complete machine upgrades, partial replacements, and daily maintenance and repair.

Key Features of HeatCore 4 UHF Lite Hotend

1. Ultra-Compact Design

• 4 mm High-Performance Heater Cartridge: Minimizes heater block volume for reduced thermal mass and faster response.

• Lightweight Construction: Lowers overall printhead weight, improving printer dynamics and speed.

2. High-Power Heating System

• 60 W Heater: Achieves target temperatures in seconds, dramatically cutting preheat times.

• 400 °C Maximum: Supports high-temperature materials with a Pt1000 temperature sensor for precise control.

3. Optimized Heat Break Material

• TC4 titanium Heatbreak reduces heat conduction to the heat sink and is more wear-resistant than stainless steel, providing stable printing.

4. Titanium-Reinforced Structure

• Innovative Screw-Support Framework: Distributes mechanical stress across the hotend, enhancing reliability during long prints.

5. V6 Nozzle Compatibility

• Standard Copper Nozzle Included: Easily swap in hardened steel, tungsten carbide, or silicon carbide nozzles to suit abrasive or high-temperature filaments.

6. Exceptional Flow Performance

• > 40 mm³/s Throughput: Guarantees stable feeding at high print speeds, maximizing productivity.

Highlights of the ALPS Pressure-Based Leveling Module

• Nozzle Calibration Probe

1. 24-Bit High-Precision ADC

• ADS131M02 Chip: Sampling at 64 kHz to detect minute pressure changes, outperforming HX711-based sensors.

2. On-Chip Signal Amplification

• 128× Gain: Enhances sensitivity and signal-to-noise ratio for reliable bed triggering.

3. Advanced Noise Reduction

• Low-Drift Reference & Kalman Filtering: Slashes measurement error by over 90 %, delivering ultra-stable readings.

4. Plug-and-Play Threshold Adjustment

• USB Interface: Allows real-time threshold tuning on a PC—no coding or firmware tweaks required.

5. Broad Firmware Compatibility

• Modular Integration: Works seamlessly with Klipper, Marlin, RRF, and other popular firmwares for custom pressure-based leveling workflows.

We provide a 1.5 meter cable for the ALPS module to connect directly to the motherboard Uart interface.
