Please make sure that the mounting plate is paralleled to the X-axis beam. The top left screw hole may not alignment on some cloned CR/Ender printers please just leave it empty.
- Page 3 6. Please make sure that after tightening the heat breaker and nozzle into the AL-BMG-AC extruder body the heat block position should looks like shown in the picture down below. 7. Install the thermistor and heater cartridge to the heat block as shown in the picture down below.
- Page 4 8. Prepare two M3x10 screws and spring washers. Use them to tighten the extruder assembly to the AL-BMG_mounting_plate. Please use the ball head hex wrench within this kit.
- Page 5 9. Pull the fans wires through the guide groove on the back of the AL mounting plate like shown down below.
- Page 6 10. Please prepare the rest parts of extruder and try to install it to the body.
- Page 7 11. Install the motor gear as shown in the picture down below. 12. Put all the wires into the channel of the cable_bundle_support after that try to install the motor to the extruder assembly. Motor cables must be oriented towards the mounting plate.
- Page 8 13. Align the stepper motor shaft with the hole below the white main gear. Push it in gently. Slightly rotate the main gear to allow for the insertion. Please also check if all the wires are in the channel. 14. Insert the 3x M3X35 screws with spring washer into the screw hole of the extruder. Use the 2.5 Hex Key to slightly tighten the screws.
- Page 9 15. Rotate the white main gear to check if it rotates smoothly. Use the 2.5 Hex Key to tighten the screws, one by one. After that please install the silicone sock to the heater block. 16. Press three M3 nuts into the 5015_fan_mount_ac printed part.
- Page 10 17. Install the 5015_fan_duct to the fan mount part by one M3X10 screw as shown down below. 18. Install the fan mount assembly and 3010fan into the extruder copper heat sink by using two M2.5x16 screws (not self-tapping). Don’t over tighten the screws it may damage the threaded hole.
- Page 11 19. Install the 5015 fan by using two M3X20 screws. 20. Prepare the Thumb Screw Assembly. Take the thumb screw and insert it in the hole of the hinge until you feel it tight.
- Page 12 21. Insert the nylon filament into the channel till it reach the end of the channel.
- Page 13 22. Open one end of the textile sleeve and slide it on the cable bundle leading from the extruder motor. Don't forget to include the nylon filament inserted earlier. 23. Take 2 zip ties and insert them into the holes on the cable_bundle_support.
- Page 14 24. Gently twist the sleeve to make it smaller and tighter around the cables, orient the sleeve's seam backwards, then slide the sleeve towards the extruder. Tighten the zip ties and cut remaining parts. 25. Recommend cable management method shown in the picture below.
- Page 15 26. Stick the heat sink to the extruder body like the picture shown down below for further improve heat dissipation.

- Page 17 Extruder Motor Connection 1) You can plug the motor 4P connector to the board directly. If you want inversion the rotation direction simply reverse the connector of the motor. 2) If the motor wire is not long enough or you don’t want to open the machine to plug the connector you have to change the connector of the new extruder motor.
- Page 18 Do not care the black wires sequence now just splice it one by one. Make sure the 1-red 2-blue 3- green 4-black.
- Page 19 After replace the connector you can plug the new extruder motor into the old CR/ENDER extruder motor connection wire.
- Page 20 After plug the motor to your printer please test the rotation direction of the motor. If you want reverse the direction you can change the sequence of the splice as shown down below. (blue and red) 1-bule 2-red 3-green 4-black. CR-10/S Print Head Connection There is one 8-PIN aviation plug wire for connect the new print head to CR-10/S control box.

- Page 22 Auto bed leveling sensor installation: M8/12/18 proximity sensor: Press one M3 nut into the groove of the M8/12/18 sensor mounting bracket Using two M2X8 screws to install the mounting bracket to the two threaded holes of the extruder body Please align the hole carefully and gently tighten the screws or you may damage the threaded hole.
- Page 23 Insert the sensor to the mounting bracket and fix it by one M3X10 screw. Adjuest the hight of the sensor to meet your requirement. Insert the cables to the textile sleeve and make sure the cables are not interference with anything of the extruder assembly.
- Page 24 Mount the BL-touch to the bracket using two M2.5 self-tapping screws and springs provide in the BL-touch kit. Adjuest the hight of the BL-touch sensor to meet your requirement. Insert the BL-touch cables to the textile sleeve and make sure the cables are not interference with anything of the extruder assembly.
