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.

Protect your 3d printer fans

image_pdfimage_print

Protecting your 3D printer fans is increasing the lifespan of your 3D printer!

Protecting them from what?

  • From dust that can:
    • Reduce the performances of the fan
    • Increase fan’s coil temperature
    • Generate vibration due to non homogeneous dust repartitions
    • Making your fan noisy
  • From screw driver hitting the blades (when we have to tinker something)
  • from your fingers or any other object touching the fan’s blades

How to protect them?

filtre à air pour ventilateur 40mm

Important points about dust filters:

They will protect your fans from dust but might decrease maximum airflow by doing so.

So make sure to never use dust filters on Hotends cooling fans as they always need to keep their maximum airflow.

in this case consider cleaning them often manually.

TMC (TMC2100 / TMC2130 / TMC2208) family are here!

These famous silent stepper drivers integrate the following advanced features:

Features in detail:

Here is the description of each feature

  • StealthChop & Spreadcycle

StealthChop allows to have silent and performant stepper motors 

Stepper motors running at low speed show a phenomenon called magnetostriction producing high pitch audible frequencies.

The driver is regulating the voltage modulation of the motor in order to minimize current fluctuations. The resulted noise level is around 10dB(A) which is lower than standard modes.

The Stealthchop performances are described in details here: Pdf available here

Here is a summary chart showing you which mode is better suited for your application

For low speeds and average acceleration: use mode Stealthchop

For average/fast speeds and accelerations : prefer mode SpreadCycle

SpreadCycle & Stealthchop comparison chart, pros and cons

SpreadCycle & Stealthchop. Pros and cons

here is the official video about Stealthchop and SpreadCycle

  • Stallguard2 & Coolstep

– full documentation of StallGuard2 & Coolstep available here

Stallguard2 Allows to senselessly measure with high precision the load resistance using back EMF feedbacks inside the motor coils.

In order to get reliable measurements, the stepper motor must work in micro stepping mode.

Coolstep adapts the current inside the coils based on the load on the motor shaft measured  Stallguard2 . The energy consumption can be reduced by 75%. Heat dissipation is also greatly impacted.

Here is another official video showing Stallguard and Coolstep modes

About Coolstep:

When an open loop driver is about to loose a step feature DcStep will reduce the motor speed in order to adapt to the load. DcStep maintains the motor position and step count.

A working range is needed in order to make sure the feature is functioning properly so that the motor torque and speed are maintained in a reasonable range.

With this feature, the stepper motor is acting as a DC motor in terme of energy efficiency.Meaning that the speed is reduced if the load is too high in order to increase motor’s torque.This allows to keep the motor position and step counts.

This mode is used in average or high speed ranges

Here is a graphic showing the working range of DcStep

SPI cable for TMC2130

This cable is compatible with Ramps 1.4 / MKS GEN 1.4 / MKS GEN-L and is available here

It allows to connect 2 TMC2130 drivers to the SPI port (often used for X/Y axis).

TMC2130 SPI cable for 2 motors

it’s connected to the AUX-3 of the Ramps 1.4 board

Special Note about the SPI cable:

With Ramps 1.4 Using this as is requires that you don’t use any LCD screen as the SPI channel will be used / link with the LCD screen. You can still use this port + LCD screen if you somehow manage to attach the wire on top of the LCD connector bread board.

If you are using MKS GEN boards, you will have a separate sets of pins available and you will be able to use LCD screen without soldering.

Note however that pin D49 (black wire) is used for the SD card detect pin so it will be already in use when you will configure your Y axis driver!

Also note that pin D53 (Blue wire) is used for the SD card Init pin so it will be already in use when you will configure your X axis driver!

The workaround is to remove the black wire from the 2×4 pins connector and connect it to pin D44 on the AUX-2 .

Same for for the blue wire, connect it to D42 on the Aux-2

Tip with the Dupont housing:  With the TMC2100 drivers you should already have a 4 pins cable with separate pins. You can remove 1 single pin black dupont connector housing and use it on the black wire you have just rewired.

On marlin side you just have to reroute the D49 pin to D44 and D53 into pin D42

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!

CR-10, 220V 600W

Heat-bed upgrade – 600W / 220V for Creality CR-10 / E10 3D printer

image_pdfimage_print

This page describes the way to setup this 600W / 220V silicone heat-bed upgrade from 3D Modular Systems . This upgrade is compatible with Creality CR-10, also potentially compatible with Anet E10

Upgrade content

  • 1 silicone heat-bed 220V / 600W
  • 1 static relay
  • 1 Grounding kit
  • 1 cable tie kit
  • 1 spiral cable tie

Heat-bed disassembly

Remove the glass from your bed.

Remove all 4 screws from your heat-bed

Return your heat-bed

Place the silicone pad so that the holes fits the bed screw holes.

Remove the protective film

Make sure to place the silicone pad so that the power supply cables are placed on the same corner as the original cables.

Note here the location of the power supply cables.


Re-use of the existing wiring

The main purpose here is to re-use the existing wiring

You have several choices here:

  • Simply cut the power supply wires (Red and Black)

Make sure not to cut the 2 small white wires!

  • Or un-solder them from the PCB bed


Separate the 2 power wires from the temperature sensor.


Insulate the heat-bed

The more efficient way is to use simple aluminum foil for cooking.

Warning! the aluminum foil has 2 different faces

  • 1 shiny side
  • 1 mat side

Use the shiny face so that it faces the black side of your bed.

The mat face has to face you.

Using a fine cutting device, carefully remove the excess of aluminum and open up the dedicated square holes .

Secure everything using kapton tape.

Kapton tape is specially made to handle high temperatures

It is also a great electric insulator.

Make sure to use proper tape

Place 4 Kapton strips along the sides of the bed in order to properly secure the whole system over the black heat bed surface.

Using a fine cutting device, you can remove the excess of tapes on the corners

Finally place a diagonal strip to secure everything.

Re-install the heat-bed and the glass.

 

 


Cut the sheath holding the power wire and the thermistor. Use a simple pair of scissors.

Make sure to cut only the sheath. Avoid cutting the wires inside the sheath!

Use a pair of cable ties to secure the thermistor wires with the bed power wires.

You can use the spiral sheath to secure the wires.


Static relay installation

Remove the blue extrusion cover located inside the left side of the chassis, at the back.

Cut about 8 cm


Static relay installation without cover

Install the static relay using a pair of M4x8mm screw and a T-nut.

Take special precautions on the orientation of the relay. The 3-32VDC side has to be facing the Z axis stepper motor. The 220V side must  point toward the outside of the chassis.

Connect the Red wire of your heat-bed that you previously cut and connect it on the « + » terminal of the static relay (terminal number 3)

Also connect the Black wire from your heat-bed (that you also previously cut) on the « – » terminal of the static relay (Terminal 4)

Make sure to take into account the polarity on the static relay!

Wire both Terminals from the 220V silicone bed on the static relay terminals . Here there is no polarity

You should have a red enclosure provided with the static relay . You just have to position the static relay on the side where the silicone bed power wire are going out.

If you have this red enclosure you can skip the next few steps that tells you how to connect you heatbed to you static relay.

Make sure to insulate the 220V  of the static relay using Kapton tape.


Ground wire installation.

You will need a pair of washer, 1 M4x8mm screw and 1 T-nut.

insert the screw and the washer inside the ground wire round terminal from the heat-bed.

Take the 2nd ground wire provided

Connect the 2 ground wires at the same location on the chassis, here pointed by the arrow.

The last washer is inserted at the bottom. The T-Nut allows to secure the ground wires on the chassis.

The 2nd ground wire has to be attached under the heat-bed.

Unscrew the adjusting knob under the bed, on the corner near the static relay.

The 2 washers allows to make contact between the ground wires and the metallic side of the bed.

1washer o each side of the ground wire terminal.

The adjusting knob secures everything.

you can use the spiral sheath in order to finalize the wiring.


That’s all!

You can use your heat-bed now.

On the electronic side you have no changes to make.

You heat bed should reach the following temperature

  • 60°C in less than 1 minute 10 seconds
  • 110°C in less than 3 minutes
