Step 1 Preparing
Preheat the nozzle to 220 Celsius from the LCD menu, then unload the filament from the hotend.
Remove the Teflon tube from the hotend.
Before moving to step 2, remember to turn the printer off and unplug it from the socket!
Step 2 Disassembling the hotend
Remove the hotend housing and disconnect the hotend thermistor.
Release and remove the two screws that secure the hotend, then unplug all the cables on the extension board.
Remove the extension board and the part cooling fan.
Remove the strain gauge.
Step 3 Disconnecting the hotend cables
Remove the bottom cover and disconnect the cooling fan.
Disconnect the heater cartridge.
Cut off the heat-shrink tubing from the connection wire. Avoid cutting the cable.
Remove the old heater cartridge.
Step 4 Install the new hotend kit
Fix the new strain gauge.
Install the new hotend.
Run the cables of heater cartridge through the textile sleeve.
Insert the both heater cables into the connector.
Make sure the cables are fully inserted and tightened!
