The ALPS module supports plug-and-play USB threshold adjustment with no custom coding needed.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Which 3D printers is the FluxHeat V6 2.85mm hotend designed for?\u003c\/h4\u003e\n\u003cp\u003eA: The Mellow FluxHeat V6 2.85mm hotend is designed for popular DIY 3D printer builds including Voron, BLV, VzBot, and Hevort platforms. It is specifically optimized for printing with 2.85mm diameter filaments including flexible TPU materials and high-temperature engineering filaments.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I swap out the nozzle on the FluxHeat V6 hotend?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. The FluxHeat V6 uses a standard V6-compatible nozzle that is easily interchangeable. You can swap between copper, hardened steel, tungsten carbide, or silicon carbide nozzles to suit your material — whether standard PLA\/PETG or abrasive and high-temperature filaments. Hardened steel nozzles in sizes from 0.4mm to 2.0mm are available as add-on sets (Sets 9–15).\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the maximum printing temperature of the FluxHeat V6 hotend?\u003c\/h4\u003e\n\u003cp\u003eA: The FluxHeat V6 supports temperatures up to 350°C, thanks to its 96W ceramic heater and NN PT1000 temperature sensor. This makes it suitable for a wide range of engineering-grade and high-temperature 3D printing filaments, as well as flexible materials like 2.85mm TPU.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does the ALPS leveling module require any special wiring?\u003c\/h4\u003e\n\u003cp\u003eA: The ALPS module comes with a 1.5-metre cable that connects directly to your motherboard's UART interface.
