Extruders motors installation on the chassis

double extrusion E3D chimera, installation des moteurs d'extrusion
Extrusion motors are to be installed on the top of your chassis You can attache them on the spool holders extrusions as follow.
The 2 pneumatic connectors are to be installed at the output of the extruders. They will hold the ptfe tubing later on. In the kit you should have 2 extrusion gears. Make sure to install them both, 1 on each extruder. the goal here is to have the same extrusion gear on each extruder to make things easier later on. You will need to calibrate your Control>Motion>Estep/mm after you update your firmware.

PTFE tubing installation

You can now install the ptfe Tubing between the hot end and the different extruders. Important note: the left heating block corresponds to the extruder E0, and the right side heating block corresponds to the extruder E1 You need to cut the tube to length so that they are as short as possible and still guaranty smooth motion all over the print volume. A good tip would be to make sure that the hot end nozzle is as low as possible (near touching the bed) before cutting the tube, in order to have an optimal tube length.

Nozzle alignment

You can now align your 2 nozzles:
  • Make sure that your X axis is as parallel to your heat bed as possible
  • Lower the hot end until 1 nozzle is touching the bed
  • Using the 2 small screws on the side of the heat-sink, you can adjust the 2nd nozzle to that it also touches the bed.

Electronic wiring

Here is the wiring diagram of the E3D Chimera dual extrusion upgrade
Dual extrusion E3D Chimera Wiring diagram

Extruder 2 (E1) installation

You first need to install the driver for your new extruder motor on the remaining driver slot. Warning! Carefully note the driver orientation, the location of the small heat-sink and the small round potentiometer. They must be on the same orientation as the other drivers

Stepper motor driver calibration

You will now calibrate the stepper motor driver using a Ceramic screws driver (provided with Scalar L/ XLP)

Reminder on the Ceramic screw driver

This screw driver is electrically insulated. It’s used to adjust potentiometers when powered If you are using a standard non insulated screw driver you may damage your stepper driver.

For the calibration purpose you will also need a multi-meter with the  2V DC caliber selected  (or similar).
  • Place the multi-meter black probe on the  USB connector metallic shielding of the arduino board (blue) located below the Ramps board (red).
  • Place the red probe over the small round potentiometer located next to the heat sink
  • Measure the voltage, you want 0.850mV
  • Using the ceramic screw driver, turn the potentiometer clockwise to increase the voltage.
  • Turn counter clockwise to decrease the voltage.

Fan extender board installation

RRD fan extender
This board is used to replace the power transistor that you re-used for your second hot end heater cartridge. You will need it to power your PLA cooling fan. Install it over the « servo » extension pins on the ramps 1.4 board (same for MKS gen boards)
This board need an external power supply in order to work. You need to unplug the E3D 30mm cooling fan from the « Y » shape splitter cable. Connect another « Y » splitter cable to it and plug back the 30mm fan to one of the available end. On the remaining end, connect the 20cm Female-Female extender cable. The other end of the cable is to be connected to the 12V input of the fan extender board (here on the left) Warning! take precautions with the polarities! Now connect the PLA cooling blower fan on the D11 location on the fan extender board.

Firmware upgrade

You need to upgrade your firmware in order to take into account your 2nd extruder. The upgrade procedure is located here The compatible firmware are labeled « Dual extrusion Chimera » If you 3D printer version / model is not listed, please make sure to contact us so that we can provide it.

Precautions after upgrading your firmware

  • Check that all your stepper motors are still turning in the proper direction. If not, just flip the motor connector on the electronic board side.
  • You will need to move the location or your existing X axis end stop. Push the hot end left until the right nozzle is located on the edge of the left side of the bed.  The left nozzle must get outside of the bed area. Now push the end stop against the X carriage and you are set.
  • You will also need to adjust ZOffset before printing. The probe tip must be around 1-2mm above the nozzle tip.

Upgrade double Z CR-10

You can use some tape in order to make sure the 4 wires are held together

Upgrade double Z CR-10

Use some cable tie to make sure the internal cables are properly held on the box.

Upgrade double Z CR-10

Step6 – Stepper motor calibration

Using the ceramic screw driver provided with the upgrade kit, you need to adjust the stepper driver current for both Z axis motor to be working.

tourne vis céramique

The best practice is to use a voltmeter

If you have a voltmeter, use the caliber closest to 2V DC .

Place the « + » probe directly on the metallic cap of the driver potentiometer.

Place the probe « – » directly on the GND terminal of the power supply where the big black cable is located at the bottom.

Warning! The next step requires the electronic box to be powered on!

Make sure to use the ceramic screw driver as it’s insulated. any other screw driver may damage the driver.

Power on the electronic box, measure the voltage as explained above.

Using the ceramic screw driver, turn clockwise so that the voltage is reaching about « 1Vdc »

Using the LCD screen, lift up and down the z axis (prepare>Move axis >Z)

If the Z axis is moving freely then you are done. If not you may need to slightly increase the voltage.

If you don’t have any voltmeters, using the LCD screen, lift up and down the Z axis.

Turn clockwise until both stepper motors are able to properly lift the Z axis

Once finished you can power down the electronic box, unplug the power coord, and screw the electronic box back to normal.

You are done!

Scalar Upgrade – Dual Y (Double Moteur Y)

Cette page décrit les différentes étapes pour installer l’upgrade Dual Y (double moteur Y)  disponible ici

Cette upgrade est compatible avec les imprimantes Scalar L et Scalar XL Premium.

Le but de cette upgrade Dual Y

Cette upgrade à pour but de rajouter un moteur au niveau du système d’entraînement existant.

Elle permet d’avoir un moteur à l’arrière ainsi qu’à l’avant du système de déplacement du plateau.

Les 2 moteurs tournent dans le même sens .

De plus, ils sont reliés électriquement au même driver moteur.

Ceci leur permet d’être parfaitement synchrone.

Ces 2 moteurs permettent d’accompagner les courroies dans les 2 sens.

Le plateau est donc toujours parfaitement tiré dans les 2 directions .

Raccordement électrique

Upgrade DUAL Y

Le raccordement électrique s’effectue par dessus l’installation initiale.

Pour ce faire il vous faut:

  1. Débrancher le câble moteur de votre axe Y en notant le sens du connecteur et la positions des différentes couleurs composant le câble.
  2. connecter le câble en forme de Y au niveau du connecteur du driver de l’axe Y. L’idéal est de placer les fils rouges du côté ou se trouvait le fil rouge du moteur précédemment.
  3. Reconnecter le moteur d’origine sur une des 2 sorties mâle du dédoubleur.
  4. Raccordez maintenant le nouveau moteur sur la dernière sortie de câble.
  5. Effectuez un déplacement vers l’avant ou l’arrière du plateau à l’aide de votre afficheur LCD
  6. Si le plateau bloque et que les moteurs font du bruit c’est qu’un des moteurs est raccordé à l’envers. Inversé le sens du connecteur du nouveau moteur.
  7. Effectuez à nouveau le test . En principe maintenant votre plateau devrait bien se déplacer en avant et en arrière. Vérifiez que le sens de déplacement correspond au même sens que celui d’origine ( un déplacement positif doit éloigner le plateau du contact de fin de course).
  8. L’installation est finie.
