Ender 3 All Metal Hotend 24V 40W Precision Kit, High Temperature Plated Copper Nozzle,Heater Block, for 3D Printer Ender 3, Ender 3 V2, Ender 3 Pro.（24V Plated Copper Kit)Description Item model number Wan191224 Style 24V Plated Copper Kit Compatible Material Titanium, Polylactic Acid, Acrylonitrile Butadiene Styrene, Metal, Copper Material Copper Compatible Devices Laptop, Personal Computer, Smartphone Package Dimensions 6.93 x 3.94 x 0.39 inches; 3.53 ounces

• These nozzles are engineered for ultimate high temperature performance. Made from a special high temperature copper-alloy with a softening point of well above 500°C, and with much-increased thermal conductivity these copper nozzles are perfect for high temperature applications, while working perfectly with everyday filaments like PLA, ABS and spoolWorks EDGE.
• The Plated Copper Nozzles and Plated Copper Heater Block is very temperature resilient, and will not start to soften or anneal until way beyond 500°C, making it perfect for the high-temperature 3D printing that other nozzles can't handle.(but is particularly important at temperatures above 280°C where a silicone sock can't be used.)
• The Heatbreak replaced by TC4 material into GRADE5.High quality raw material.High precision production to provide excellent thermal isolation between heater and cooling block.Strict quality assurance.No burrs,Clean surface.(Reducing the chance of filament clogging)
• The Heatsink and Heater Block Is high quality fine processing aluminum .It is not low quality or cheap aluminum.Coupled with high-precision CNC machining, and strict quality assurance Which brings the high-quality HOTEND Kit.
• Fits: Ender 3, Ender 3 V2, Ender 3 Pro 3D Printer Ect. Note：If you plan to print high temperature materials, the temperature is over 300℃. Please replace the thermistor.

If you are facing PLA clogging problem, please try the followings:
1. Increase the retraction speed. The speed may have being limited in the firmware try to change it. G-command "M203 E200".
2. Increase the extruder acceleration. Check your firmware settings. G-command "M201 E9000". 3. Reduce the retraction length. It depends on your machine setup.
3. Increase the nozzle temperature by 5-10 degrees.
5. Do not install the 2 screws for support the heat block like the stock hotend on the CR-10 printer.
6. Make sure that there is no gap between the heatsink and the heat breaker.
