OMGEXTRD F2

  • 1.75mm

  • ENDER Long-distance extrusion

  • Upgrade example model:

  • Net weight: 64g(no motor)

  • Double drive 1:3 Gear Ratio

  • E-steps:385 subdivision 16 step angle 1.8°

  • F2-set kit does not include stepper motor

Notice:

Long-distance
STL print slicing software (CURA, etc.) Retraction setting:
Suggested value: Speed 30mm/s ,Retraction Distance: 7mm

NOTE:

F2 has been replaced with a new size large gear, the diameter is 8.4mm, so the E-STEP value needs to be reset to 363.

If using a 42 stepper motor, the step angle is 1.8°, the motor drive is 16 subdivisions, and the gear ratio is 1:3E-STEP:363

If ​​using a stepper motor at 36 pitch, the pitch angle is 0.9°, the motor drive is 16 subdivisions, and the gear ratio is 1:3E-STEP: 726

  • A Install the filament Press bearing using a Cross screwdriver

  • B Put in the middle part (see the picture), Insert the Spring and Screw in the fixing nut (M6)

  • C Install the Teflon bowden, Blue bowden clip is used to fix the Teflon tube(4mm) not move.

  • A  Install stepper motor gear,Note the gear direction

  • B  Install M3-6 4pcs  screws (don’t tighten frist)

  • C Adjust the position of the stepper motor gear (as shown in the picture)

F223.jpg
  • A  Check Drive gear 2 precision mini bearings up and down is installed (pre-installed in factory)

  • B  Adjust the gear gap, Free and relaxed rotation is the standard.

  • C  Then tighten the M3-6 *4pcs screws fixed with the motor

  • A Hold down the big gear and keep it still not rotating.

  • B Pulling the filament, Testing Pulling force.

  • C Spring pressure is designed to be limited, spring do not need too tight, Only damage the spring. Recommended that the spring tightening screws are flush with the shell.

Note: The surface of the driven wheel is flat, Function is to Press the filament. The power to pull the transmission filament comes from the driving wheel. The surface of the Pressure wheel has teeth-only damage to the filament-and will not have any good effect on the extrusion effect.

After installation. Need to adjust the E-step to 363  .Pls see  E-step

To complete the installation, you need to modify 2 steps:

1/

E-step  Value needs to be adjusts to 363 -Drive subdivision 16 Step angle 1.8° Gear diameter 8 Gear ratio 1:3

For exampleENDER series :Original value: 93

2/

Stepper-current-adjustment needs to be adjusts to 0.8-Vref

36 motor nama14 adjusts the driving voltage to 0.8-Vref
If the original motor is used, the drive voltage may not be modified.

To complete the final work!

  • The current adjustment of the stepping motor is controlled and adjusted by the voltage of motor driven .

  • Upgrade the extruder to 1:3 deceleration,

  • And the torque output of the motor is 1/3 of the normal.

42 motor nama17 adjusts the driving voltage to 0.8-1.0 A.
36 motor nama14 adjusts the driving voltage to 0.8-1.0 A.

Different 3D printer motherboards have different setting methods.
