MK10 All Metal Hotend Kit Installation Guide
Assembly tools are not included with the package, however hex keys and wrenches will be necessary for installation. The keys should be included in your 3D printer's tool set, wrenches will need to be obtained separately.
- 3mm Hex Wrench (comes with 3D Printer accessory kit)
- 2.5mm Hex Wrench (comes with 3D Printer accessory kit)
- Adjustable Wrench or Pliers
- 9mm Wrench (or second Adjustable Wrench)
- MK10 Brass Nozzle
- MK10 Cooling Block
- Thermal Barrier Tube
- MK10 Heater Block (included in full kit only)
- HEX M3 Thermistor (included in full kit only)
Use an M3 hex wrench to loosen and remove the two screws located on the bottom of the cooling block, then slide it out of the carriage, careful not to place any strain on the wires.
Use an M2.5 hex wrench to loosen the set screw on the bottom of the heater block. Remove the heater cartridge and thermistor from the assembly.
Using the new components included with the kit, thread the shorter end of the all metal heatbreak into the cooling block until it is tight.
Thread the cone shaped end of the all metal heatbreak into the top of the heater block, leaving it loose. The heater block set screw should be facing away from the cooling block as shown.
Holding the heater block in the desired position, thread the nozzle in to the bottom of the block until it is flush against the heatbreak. We will tighten the nozzle once more in later steps, which will close the inner gap and lock the hotend in place.
Insert the heater cartridge into the new heater block and then tighten the set screw to secure it in place. Screw the new Hex M3 Thermistor in as well (for full kit) or install stock thermistor with M3 screw, washer and cotton insulator.
Place the cooling block back into the extruder carriage, then thread the (2) M3 mounting screws from the bottom and tighten them down.
Insert the (2) M3 screws into the bottom holes of the 40x40mm fan, then slide the plastic spacers on from the rear side. Place the metal heatsink with blades facing towards the fan and press them assembly together.
Fit the entire fan assembly into the cooling block, where the screws should pass through to the other side.
With the plug facing upwards, position the extruder motor on the right side of the carriage and align the exposed screw holes with the M3 screws. Tighten both screws to pull both sides of the extruder assembly together.
Note: Once the motor is in place, move the carriage to the right side of the printer frame to brace it, making it easier to tighten the screws.
