- Confirm the proper seating of the belt by moving the carriage from side to side.
STEP 16 – PREPARE THE HOTEND
- Take the silicone sock off of the hot end.
The hot end has been heated and tightened to spec at the factory, so there is
no need to do the nozzle hot tightening procedure on a brand-new hot end
unless you are replacing the nozzle.
See the last page of this document for the complete nozzle replacement
procedure. Most importantly, ensure the thermal break is fully seated first,
then tighten the nozzle to 30-inch pounds of torque while preheating to
precisely 220C.
STEP 17 – INSTALL THE HOTEND
- Insert the hotend assembly into the extruder.
- Verify the thermal break is seated as deep as possible in the extruder. Compare with the reference image on the left.
- Tighten the set screw. (1.5mm wrench)
STEP 18 – INSTALL THE THERMISTOR AND HEATER CARTRIDGE
- Place the heater cartridge and thermistor into the heater block. Ensure the thermistor is fully inserted into the heater block, with the glass bead not visible.

STEP 22 – INSTALL THE PTFE BRACKET
- Attach the 3D-printed PTFE Bracket beside the Filament Runout Sensor using the provided M3 screws and M3 nuts.
(2.0mm Allen wrench)
STEP 23 – ATTACH THE FILAMENT GUIDE TUBE
- Insert the filament guide tube (original Bowden tube) into the PTFE Bracket.
- Insert the other end of the filament guide tube into the top of the NG Extruder.
- Secure both ends of the filament guide tube in place by installing a red C-clip under the Bowden couplers on each end of the guide tube.
STEP 24 – INSTALL THE EXTENSION CABLE
- Attach the provided extension cable to the printer’s original E cable.
- Attach the other end of the extension cable to the NG Extruder motor.
Use the provided extension cable.
The provided cable has the special wiring pinout required to connect the LDO
motor to the CR-10S Pro V2 and CR-10 Max.
A different extension cable will not work properly.
STEP 25 – CABLE MANAGEMENT
- Use the provided zip-ties to manage the cables neatly
Ensure there is some slack in the stepper motor extension cable near the motor
STEP 26 – ADJUST THE GEAR TENSION
- Adjust the gear tension by rotating the brass knob.
The gear tension can be gauged by measuring how much of the brass knob’s
threads are exposed. (Distance from the head of the brass knob to the aluminum
extruder arm.)
The good starting point for stiff filaments such as PLA, PTEG, and ABS is
1.75mm of exposed threads (use a piece of 1.75mm filament as a gauge as shown
in the image on the left).
A good starting point for flexible filaments such as TPU, loosen the knob
until about 2.75mm of the threads are exposed. Loosen the knob two full turns,
if starting from 1.75mm.
STEP 27 – POWER ON THE PRINTER
- Plug the power cable in.
- Turn the 3D printer on.
STEP 28 – UPDATE THE ESTEPS
The E-steps will need to be set to 400 in the printer settings by printing a g-code file.
-
Download the Esteps G-code from the link below.
Download -
Save the G-code file onto your MicroSD card.
-
Insert some filament into the Filament Runout Sensor, so that it does not trigger a Filament Runout Alarm in the next step.
-
“Print” the Esteps G-code file on your printer.
The code should complete printing in approximately 15 seconds. It won’t
generate a 3D-printed object and won’t provide a confirmation of success, so
please allow it sufficient time to finish before proceeding.
When utilizing the SonicPad/Klipper firmware, adjust the Extruder Rotation
Distance to 8 instead of modifying the Esteps.
STEP 29 – CONFIGURE SLICER SETTINGS
- Set the Retraction Distance to 1.0mm in your slicer software.
WARNING: Do not use any g-codes that were sliced with a Retraction Distance higher than 1.5mm.
