More Guidance
It is recommended to install the fan toward the left; if toward the
right, pay attention to the gear and air vent. There are 10pcs M3
screw holes on the extruder for fixing.
The M3X8 screws provided are suitable for mounting plates with
a thickness of 3~5mm.
Please assemble the hotend with the following steps:
1. Insert the heater cartridge into the heater block;
2. Install the heat break;
3. Place the thermistor head into the designated spot on the
side of the heater block(preferably pack the spot full of thermal
grease, standard thermal grease for PC cooling purposes
should suffice)and clamp down the thermistor wire with the
included M2 screw and washer;
4. Wrap the heater block with the included PTFE tape at least 3
times for optimal thermal insulation(To achieve the ultimate
lightweight and smallest dimension, the thermistor screw and
washer can be neglected, fix the thermistor in place with only
PTFE tape);
5. Install the nozzle(the nozzle should be hot tightened again
after the heater block has been heated to printing temperature).

Light weight as low as 175g;
Flowrate boosted from 15mm³/s to 45mm³/s;
The idler arm is made of 7075 T6 aluminum, with special
blend high-performance anti-wear MoS2 grease to improve
the quick release lever haptics and enhance wear resistance;
High performance thermal grease has been pre-applied to the
heat break to increase thermal conductivity between the heat
break and heatsink to improve cooling performance;
The filament drive gear is made of tool steel plated with
nano-coating to improve hardness, wear resistance, corrosion
resistance and provides longer life when printing abrasive
materials.
