Materials[edit | edit source]
- 1 Partially assembled Hexagon hot end
- 1 Cartridge heater
- 1 Thermistor assembly
- 1 Small wire tie
- Muffler cement
Tools[edit | edit source]
- Short piece of 1.75mm filament
- 1.5mm Hex key
Note[edit | edit source]
- These instructions assume the Hexagon hot end has been partially assembled, i.e. the heat sink, aluminum heater block and nozzle have been assembled and tightened, and the cartridge heater set screw is in place. It is recommended that these components be tightened while HOT (>200 degrees C) to insure that they stay tight upon heating.
- A 30W cartridge heater is generally used, but they come in different voltages. Insure that the voltage of the cartridge heater matches your printer power supply. A 24V power supply is now recommended.
Procedure[edit | edit source]
- Using the piece of filament, force muffler cement down into the thermistor pocket in the aluminum heater block.
- Wet the thermistor bead with muffler cement and insert it into its pocket in the aluminum heater block.
- Set the hot end aside to let the muffler cement set for more than an hour.
- Insure the cartridge heater set screw is clear of the hole into which the heater slides. Insert the cartridge heater in the hole oriented so that the wires are parallel when looking down from the top to facilitate bending the wires up towards the top of the hot end. The wires should also exit from the same side the thermistor is on. Tighten the cartridge heater set screw with the 1.5mm hex key.
- Bend the wires towards the entry of the hot end and secure in place with a small wire tie. Tighten the wire tie on the hexagonal portion just off the smooth round portion of the heat sink.
