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.
