CR-6 SE E3D V6 Hotend Mounting Adapter (Threaded Heatsink)

thingiverse

Here’s my take on changing the Hotend on the CR6 to the popular E3D V6 All-Metal Hotend (Threaded Heatsink version). I designed an adapter with a center partial M12 thread and two outer M3 threads. The threaded heatsink screws into the center thread and the adapter with the hotend can then be mounted to the strain gauge using the exisiting M3 screws from the old hotend. The adapter is sized to provide the same length of the complete hotend compared to the original one. Therefore the original part-cooling fan and shroud can be used. Gcode is sliced using 0.16 mm Layer Height for Printing on the CR-6 SE (using Cura 4.8). Use 100% Infill for stability. I bought the E3D V6 clone (1,75mm, 24V, Allmetal) from Trianglelab: https://www.aliexpress.com/item/32888737278.html Installation: • Install Community Firmware Alpha 4 (https://github.com/CR6Community/Marlin/releases/tag/v2.0.7.1-cr6-community-release-4-alpha?fbclid=IwAR0evqNGY4eQezsDk4Dg9M0u6uh-LlaFuzro39c0FaDE-iWN-r20G0yge7M) • If first layer prints well print Adapter gcode (CCR6SE_CR6 E3DV6 Adapter) • Disassemble the hotend from the strain gauge following this video https://youtu.be/Q1_TRbe2ybc • Disconnect the connectors from the PCB to remove the original hotend (you will have to remove some hot glue) • Disassemble the fan from the original hotend • Cut the wires between connector and thermistor as well as heating element about 3 cm from the connector • Cut the wires from the new E3D thermistor and heater element about 3 cm from metal casings • Strip 7,5mm isolation from the wire ends • Put shrink tubing on one of each connection and join the wire ends using ferrules and crimping pliers, isolate with shrink tubing using heat gun or lighter (see Pictures) • Screw the heatsink into the adapter until there is no space between the metal and the adapter • Assemble the hotend following this guide (https://wiki.e3d-online.com/E3D-v6_Assembly) and use the fan of the original CR6 hotend instead of the new one • Before mounting the hotend to the strain gauge insert the Teflon/Capricorn tube into the hotend, install the Bowden clip and trim of the handle of the Bowden clip with pliers (see Pictures) • Mount the hotend and connect the wires to the PCB • Install the FAN cover and connect the ribbon cable • Flash modified firmware (with hotend-specific TEMPSENSOR, MAXTEMP and PID values,) to an empty SD card (FAT32, 4096 bit formatted) • Insert SD card into the printer and turn the printer on • Perform PID tuning using Pronterface as shown in this video: https://youtu.be/h9Rdid-T-Gw • Happy Printing!
