BZ 3D Ender 3 All Metal Hotend Upgrade Kit,High Temperature MK8 Plated Copper Nozzle,Heater Block,for Ender 3/V2/Pro/Max/Ender 5 /Pro/Plus/CR-10/10S/

The Plated Copper Nozzle and Heater Block 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 all filaments,including PLA, ABS, PETG,TPU,PP,PC,PA,Nylon,PEEK,PEI and composite materials containting abrasive additives,such as carbon fiber,steel,wood,boron carbide,tungsten etc. The Plated Copper Nozzle and Heater Block have high temperature resistance,high thermal conductivity,non stick surface,reduced filament adhesion,nickel based electroplating is not easy to wear performance and are very suitable for high-temperature 3D printing that other nozzles cannot handle.but is particularly important at temperatures above 280°C where a silicone sock can't be used. The Heatbreak material is upgraded from the original TC4 titanium alloy to GRADE5.High quality raw material.High precision production to provide excellent thermal isolation between heater and cooling block. The Plated Copper Nozzle and Heatbreak appearance is more shiny,thread precision improvement.The inner wall of the tube is smoother (reducing the chance of filament clogging).The interface is smoother and more precise (can effectively prevent the filament from leaking). Fits: CR-10 / CR-10S / CR-10-S4/CR-10-S5 / CR-10 MINI / Ender 3 /Ender 3 V2/ Ender 3 Pro/ Ender 3 Max /Ender-5/Ender 5 plus/CR-20 /CR-20 Pro/TronXY X5S 3D Printer Ect. After-sales guarantee: each defective item can be replacement for free or refund.If any question, please feel free to contact or QA us, BZ 3D is committed to providing you with the best service! Recommended slicer setting:
retraction speed over 80MM/S
retraction length 2.5-4MM

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.
4. Increase the nozzle temperature by 5-10 degrees.
5. Do not install the 2 screws for support the heatblcok like the stock hotend on the CR-10 printer.
6. Make sure that there is no gap between the heatsink and the heat breaker.

NOTE:

This product only supports 1.75mm filament!!! Not compatible CR10S PRO.
We found that many customers do not know how to properly install the nozzle.
Remember the core issues in the installation process.
Just make sure your nozzle and HEAT BREAK front end are tight and sealed. Otherwise, the filament will leak along the screw holes.
