Mini Hotend

Description

Benefits:

• Designed to be light for fast prints.
• Ships pre-assembled.
• Cylindrical heater for optimal and symmetrical heating of material.
• Thermistor mounted directly in the nozzle for more realistic temperature reading of the material as it comes out the hotend.
• Small, compact fan.
• Uses the new Semitec 104NT-4-R025H42G thermistor.
• A second thermistor can be added to the nozzle for dual thermistor setup.
• Mounts using 2 x M3 screws (not included) instead of a groove, which is not the most secure method.

If you want to use the hotend for a direct drive rather than a bowden setup, you need to remove the push-fit and insert a small PTFE liner or you can use a spacer. The heatsink has a chamfer under the push-fit to ensure your filament transitions smoothly into the channel if you decide to use it as direct drive.
