Prepare Hotend:
If the printer was in use, set the hotend temperature to 0°C and wait until the sensor shows a safe, operable temperature.
Power off the printer.
Disconnect Wires:
Unplug the Temperature Sensor and Hotend Heater wires from the distribution block.
Loose Wire Shroud
Unskrew a bit two bolts on the side of the toolhead to let eject wires from the wire shroud. But not to much - it can cause fan shroud removing to.
Unscrew Fastener:
Unscrew the fastener from the side where the wires are connected.
Remove Components:
Gently pull out the Temperature Sensor and Hotend Heater. They should come out easily. Be prepared for them to be covered in thermal paste.
Safety Check:
Ensure the printer's inner parts are safe to touch to prevent accidental injury.
Inspect Components:
Ensure the Temperature Sensor and Hotend Heater are serviceable and free of damage.
Apply wire ferrules:
Strip approximately 8mm of insulation from the wire tips.
Twist the exposed wire strands to ensure they are tightly wound.
Insert the twisted wire tips into the ferrules.
Use pliers to crimp the ferrules and secure the wires in place.
Apply Thermal Paste:
Apply thermal paste to the Temperature Sensor and Hotend Heater.
Insert Components:
Push the Temperature Sensor and Hotend Heater into their respective places.
Secure Components:
Tighten the fixing screw.
Clean Up:
Clear any leftover thermal paste.
Fix Wires Under Shroud
Slide wires under shroud on the side of the toolhead and tighten the screws.
Reconnect Wires:
Connect the wires to the distribution block according to the Toolhead Wiring
Check Results
Go to the Web Interface, set some temperature for the toolhead and see how it is changing on the information panel.
