Step 7: Reinstall heater cartridge and thermistors
Step 7A: Insert the heater cartridge and hand tightened the 2 retaining bolts using 1.5mm Allen Wrench
Step 7B: Secure the thermistror. [Be careful not to overtighten the screw as this can damage delicate wires]
Step 8: Turn on the printer and pre-heat hotend to 280°C (Read Part 2 if you have current hotend cannot heat above 260°C) [Do note: if you using larger adjustable wrench you may need to wait until temperature to equalised, you may need to perform a PID if you having issues reaching these higher temperature.]
The hotend is now at 280 degrees celsius.
Be extremely careful not to burn your fingers when tightening the
nozzle and the grub screws
Step 9: Using a provided spanner and adjustable wrench tightening the unit as shown in below photo, one holding the heatbreak in-place and one on the nozzle. [You are aiming for 2.5-3N.m of torque here, if you apply too much pressure at this stage you will risk shearing either the Nozzle or HeatBreak. If you are concerned we recommend the use of a torque wrench set to between 2.5-3N.m]*
Note: If the heat break rotate during heat tightened, loosen grub screw on cooling block and adjust only once heater is cooled. Be sure you have already grip heater block and it may drop if you loosen grub screw too much.
