All Metal 3DMCR10 Cr10 Hotend Brass 0_4MM Mk8 Nozzle Titanium Heated Block for Upgrade 3D Printer CR-10 CR10 CR10S Ender 2 Ender 3 Ender 5 0_4MM

Please read here: This is a drop in All Metal Conversion kit for CR-10 printers. It requires absolutely zero modification to your printer to install. Our uniquely designed cooling block eliminates need for a thermal tube. By not having separate thermal tube inside cooling block, it allows for faster heat dissipation. The manufacturing processes for HeatBreaks has been overhauled to achieve a better internal surface finish than ever before. The improved internal surface finish will help to reduce extrusion force and improve relliability on retractions. Thermal heat break is made from Titanium Alloy to provide excellent thermal isolation between heater and cooling block. Titanium is extremely strong material and offers almost 3x lower thermal conductivity than stainless steel, creating more defined meltzone. 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.
