How to Install the  Upgrade Kit for Creality Ender

Overview

Materials 

Kit Variant (if using existing heater and sensor)

1. Copperhead® Hotend w/ Copperhead® Silicone Boot and Dowel Pin
2. Boron Nitride Paste w/ Applicator Swabs
   

Required but not provided with the upgrade kit

1. Stock Creality, or aftermarket, heat sink that will accept a stock Creality heat break. Must include a setscrew (see picture)
   
    
   
2. Heater (if installing the Kit Variant)
3. Sensor (if installing the Kit Variant)

Tools (not provided)

1. Philips Head Screwdriver
2. 1.5 mm hex key
3. 2.0 mm hex key
   
4. Diagonal Cutting Plier (if installing a new heater or sensor)
   
5. Flat Head Screwdriver (if installing a new heater or sensor)

Removal and Disassembly of the Existing Hotend 

1. Ensure the hotend has been allowed to cool down to ambient temperatures.
2. Turn off the power to the printer and remove the power cord. 
3. Using a 2.0 mm hex key, remove the two screws attaching the fan housing to the gantry plate
4. Set the fan housing to the side
   
   
5. Remove the Bowden tube from the heat sink by pushing down on the top of the pneumatic fitting. This will allow the Bowden tube to be pulled out. This step can be performed at any time prior to installing the Copperhead hotend.
6. Using a 2.0 mm hex key, remove the two screws located at the bottom of the hotend
7. Using a 1.5 mm hex key, loosen the setscrew on the heat sink to release the hotend.
8. Gently pull the hotend out of the heat sink.
   
   
9. Using a Philips head screwdriver, remove the temperature sensor setscrew from the hot block and gently remove the temperature sensor. 
   
10. Using a 1.5 mm hex key, loosen the setscrew on the bottom of the hot block and gently remove the heater from the hot block.
    

Removal of existing heater and sensor

1. Using a pair of diagonal cutting pliers, remove any zip ties that are sinching the mesh cable sleeving to the wiring running from the hotend to the motherboard. 
   
   
2. Using a 2.0 mm hex key, remove the 4 screws, 3 on the bottom of the machine and one on the top, used to hold the metal cover over the motherboard.
   
3. With the cover removed, remove any additional zip ties or wraps that are constraining the hotend wiring harness. 
   
   
4. Unplug the stock thermistor from the motherboard. As depicted, this will be the "TH" port on the 4.2.2 motherboard.
   
   
5. Using a small flat head screwdriver, unscrew the two posts clamping the heater leads to the motherboard. Once these two posts are loosened you can remove the heater leads from the motherboard.
   
6. Remove the heater and sensor from the mesh cable sleeving. This can be easily done by bunching up the mesh cable sleeving and gently pulling the heater/sensor out.
   

Installation of the Copperhead® Hotend

1. Remove the Copperhead® Silicone boot from the hotend. 
2. Using a 2.0 mm hex key, remove the retaining screw located on the side of the Copperhead® hotend, to the left of the Slice Engineering logo. 
   

3. Remove the cap from the syringe of Boron Nitride Paste. Push the open end of the syringe onto the small temperature sensor hole and fill the hole with Boron Nitride paste. This will be done on the side you removed the retaining screw from. Any excess Boron Nitride Paste can easily be clean after installation with a damp paper towel/ Q-tip
   
   .
   
   
   
   
4. Dispense a pea-sized amount of Boron Nitride Paste onto an applicator swab. 
5. Using the Boron Nitride Paste on the applicator swab, coat the interior of the heater hole with paste. 
6. If needed, apply more Boron Nitride Paste to the applicator swab and then coat the heater cartridge with paste. 
7. Insert the heater and temperature sensor into the hot block. An applicator swab can be used to clean up any excess Boron Nitride Paste on the exterior of the hot block.
   
   
   
   
8. Using a 2.0 mm hex key, reinsert and tighten the hot block retaining screw. The retaining screw is used to hold the temperature sensor wire in place, as well as to retain the heater. Do not overtighten the retaining screw as this may damage the temperature sensor wire. 
   
   
9. Insert the hotend into the heat sink until it comes to a stop. With the stock heat sink, the fully inserted heat break will remain ~1.5mm out of the heat sink. Using a 1.5 mm hex key, tighten the setscrew on the heat sink to secure the hotend.
10. Reinstall the Copperhead® Silicone Boot and Bowden tube.
    
11. Using a 2.0 mm hex key, reinstall the fan housing. 
    
12. Adjust Z stop to the height of the new hotend. 
    
    

    NOTE: If installing the Kit + Heater/Sensor Variant, skip steps 13 and 14 below. Proceed to the section below titled "Installing a Heater/Sensor in the Motherboard."

    
    
13. Plug in the power cable and turn the machine on. 
    
14. PID tune your newly installed Copperhead® hotend. 
    

Installing a Heater/Sensor in the Motherboard

1. Pass the Slice Engineering heater and sensor cables through the mesh cable sleeving by bunching up the mesh cable sleeving and pushing the cable through from the hotend side of the mesh cable sleeving to the motherboard end. 
   
2. Insert the ferrule ends of the heater cable into the hotend heater post on the motherboard, one end in each post. With the ends insert, using a flat head screwdriver, tighten the post to secure the heater to the motherboard. 
   
3. Insert the thermistor connector into the thermistor port, labeled "TH", on the motherboard.  
4. Zip-tie and wrap the cables as needed. 
   
5. Replace the motherboard cover. Using a 2.0 mm hex key, install the 4 screws that secure the cover to the printer.
   
6. Plug in the power cable and turn the machine on.
   
7. PID tune your newly installed Copperhead® hotend.
