This is the Aluhotend-V7 bare version.
- The heat-sink is tapped all the way through and a hollow grub screw locking the thermal barrier in place which allows the hot-end length to be micro-adjustable which is very handy for those who want to do a dual extruder setup this also means there is no longer Bowden specific version
currently only 1.75mm hot-ends are produced.
- The hole for the heater cartridge is now a clamping system to ensure full contact around the heater cartridge
Default nozzle size is 0.4 mm
The thermistor used is #10 in Marlin please see here for more details
This hot-end requires a fan blowing on the heatsink for proper operation.
It is highly recommended that a filament cleaner is used to prevent foreign material entering the hot-end and causing a blockage
