Компактная многоцветная печатающая головка

The Diamond Hotend is a versatile multicolor FDM 3D-printer hotend. This hotend enables virtually every existing home or office 3D-printer to being upgraded into printing any color of the rainbow. The hotend system features three indepentently controlled filament lines that are combined into a single 0.4 mm nozzle output. By feeding the transluscent colors cyan, magenta and yellow any color (hue) can be produced as is demonstrated below.

Assembling

Picture shows a bq Prusa i3 Hephestos refitted with Diamond Hotend, three extruders and three custom design 500 gram CMY filament rolls

Cooling Shield - Standard Prusa i3 version

These instructions are written with bq Prusa i3 Hephestos in mind

If you haven't already done so, or you want the one with the blower fan option, download and print the Diamond Hotend Cooler Shield (for Prusa i3 at http://www.thingiverse.com/thing:720520). For normal use we recommend printing the cooler shield in PLA. For printing with materials that require higher printing temperatures, we recommend printing the shield in ABS or another material with a higher glass transition temperature (Tg).
Insert the two M3 nuts into the hexagonal holes at the rear of the printed Cooler Shield and press them into place. If necessary use a soldering iron to heat the nuts and melt them into place.
The two holes are spaced 30.5 mm apart, hence it should fit most Prusa i3 printers, but check with your printer anyways - you may have to customize this part if your printer have different specifications.
If you are assembling the version with the blower pendant, insert a M3 nut through the designated internal slot.
Apply a small amount of the thermal compound to the center hole of the Diamond Hotend.
Insert the heater cartridge into the center hole of the Diamond Hotend and press it in as much as possible. Wipe off excess compound. If there's no excess remove the heater cartridge and repeat from step 3 adding more compound. The heater cartridge must be inserted so far in that it will be held in place and partly covered by the lower fins of the HeatSinks. Failure in executing this step can lead to skewed Heatsinks, improperly tightened HeatSinks and even a leaking hotend, so please be sure to do this step right.
Dip the thermistor tip into the remaining thermal compound and press it into the 2 mm hole in the Diamond Hotend along with some millimeters of the PTFE tape tubings, which will keep the thermistor locked in place.
Stack the three Thermal Isolator Sheets, feed the wire ends through their corresponding holes, then firmly press the sheets onto the threaded part of the HeatSinks. Remove any insulator residue stuck in or on the threaded part.

Note:
At this point it is recommended to wind some PTFE Teflon tape (plumbers tape) around the threads of the three HeatSinks before assembling, this will help to avoid leakage. Another option is to use "liquid sealing" e.g. SISEAL which allows for better fitting between the hotend and HeatSink.
Observe orientation in relation to the thermistor and screw the HeatSinks loosely into the Diamond Hotend. Do not tighten yet, we will do this later.
Grasp the wire ends from the heater cartridge along with the thermistor wire ends and feed them all the way through the pointy end of the Cooler Shield orienting the shield in such a way that the thermistor is located closest to the Cooler Shield mounting plate. Press the small black Bowden Fittings into the rear ends of the HeatSinks.
Making sure the wires remain in the central opening of the Cooler Shield, press the shield into the hotend assembly. The rear end of the HeatSinks must click equally into the grooves on the Cooler Shield. Retighten the HeatSinks but be careful not to over-tighten or the Heat Breaks might collapse.
Use 3 cable ties to attach the HeatSinks onto the Cooler Shield and the fourth cable tie to attach the wires onto the rear part of the Cooler Shield (the side which has a groove where the cables will fit).
Cut off any excess of the cable ties.
Mount the fan using 4 pcs M3 x 20 mm countersunk screws. Make sure to orient the fan such that the airflow goes down into the Cooler Shield (label side of fan pointing into the assembly) and the wires coming out at the same side as the other wires.
Attach the hotend mount onto the x-carriage of the Prusa i3 Hephestos using 2 pcs M3 x 16 mm along with 2 pcs M3 washers.
To avoid filament clogging and/or meltdown of the Cooler Shield the fan must be constantly running. Be sure to connect it directly to 12 volt using the red/black extension cord. First cut the heat shrinking tube into two, slide them over each wire (black and red) and solder the bare leads from the fan onto the extension cord then carefully shrink the tubing using the flame of a lighter.
- RAMPS: The other end of the extension wire connects to the power input terminals of the RAMPS board.
- RUMBA: On a RUMBA board there is a 2 pin terminal referred to as 12V, connect the extension wire here.
Пожалуйста, соблюдайте полярность: Красный провод положительный (12V +) и черный провод отрицательный (GND -)
Strip the outer 5 mm of the heater cartridge wire ends and mount them in the Hotend power output screw terminal.
- RAMPS: On the RAMPS board this is done via the terminal referred to as D10. The thermistor plug goes to the pins marked T0.
- RUMBA: On a RUMBA board this is done via the terminal referred to as HE0. The thermistor plug goes to the pins marked T0.
Before using your Diamond Hotend, in order to avoid liquid plastic leakage the HeatSinks must be properly tightened while hot. Heat up your Diamond Hotend and tighten the HeatSinks. (While you are at it, make sure the top fan is running or you will end up with a hotend mount meltdown). You may use a water pump size pliers (to avoid making marks or scratches on the HeatSinks you could put a piece of cloth in between) but please be careful not to over-tighten as the weakest spot is the HeatBreak and it cannot take a whole lot of stress. For further details also see E3D assembly instructions
- Только для пользователей RUMBA: When connecting the Z-axis motor wiring on a printer with dual Z-motors you will find that there is only one plug on the board. A simple workaround is to strip the wires and connect them in parallel to the Z-screw terminals. Another workaround is to solder the wires into one plug. Please note the colors or the order of colours shown here is not necessarily the same as found on your printer (please refer to your printers documentation). If you find that motor(s) are turning the opposite way as intended then simply switch off the machine, turn the plug(s) by 180 degrees.
Bowden tube hints

Attaching the bowden tubes
- Before inserting the bowden tube into the E3D HeatSink, cut off a small piece perpendicular the end as to make a perfect right angle cut. This is to eliminate the gap between the tube and the hotend which will also help avoid clogging.
- At the motor end of the bowden tube drill the inside of the tube using an exacto knife (or another sharp tool) in order to create a small funnel. When loading filament this will help guide the filament into the tube. Be absolutely sure to remove all excess from drill remainings before inserting the tube into the extruder coupling since you do not want this residue ending up inside the hotend as it will most likely cause clogging of your hotend.
- Prior to applying filament you must fully insert the bowden tubes (approx. 53 mm) into the three HeatSinks. If you do not, the HeatSinks will get clogged and the filament get stuck! When fully inserted use your nails or a small plier to lift the black tube retention ring approximately 1-2 mm's and you should then be able to insert the tube another 1-2 millimeters down. Furthermore you may insert a Bowden Tube Clip under the retention ring to hold it tight against the tube.
General bowden hints
- Using even lengths on all three tubes is recommended as these will be easiest to manage in case you want to swap any of them at a later point.
- The shorter the bowden tubes the better, this is because it decreases both filament corrugation and resulting friction to the inside of the tube. The optimal length of the bowden tubes however depends on how the hotend moves. Be sure to make the tubes long enough to be able to reach all hotend positions while avoiding any sharp bends.
  - Roughly speaking most printers with a standard 20 x 20 cm print area (at least those with hotend moving in only one dimension having a clearance in the order of 200 mm) will need the tubes to be approximately 50 cm (depending on extruder placement).
  - On Witbox (which has a print area the size of a sheet of A4 paper) the tubes need to be approximately 65 cm.
- If you have a bowden tube that is stuck with melted up filament inside and you are having trouble getting it loose, take a cup of hot water (60 deg. Celcius or above) and dip the tube into it for about ten seconds. This will soften the filament and you should be able to push out the blockage with ease by using another piece of filament.
- Some people have reported trouble fitting the bowden tube inside the E3D HeatSinks, and it turns out the outer diameter of the tube is approximately 0.1 mm larger than expected. To accommodate this, one of following actions can be taken, treating one pair of HeatSink/bowden at a time:
  - Carefully scratch or scrape the surface of the bowden tube by sanding or using an exacto knife until it fits the HeatSink.
  - One user reports: heat up the heatsink (if necessary use a heat gun) and the bowden tube should slide right in. If using the E3D-LiteV6 please remove the black ring on beforehand (use nose pliers or similar) as it can not withstand the temperatures involved in this procedure.
Cleaning up a clogged hotend

LiteV6 1.7 version

If your extruder jams or is clicking, nothing comes out of the tip and filament is stuck, consider going through the following steps:
- First thing is to check whether the bowden tubes were fed all the way through the heatsinks. This is very important as any gap between the tube and the hotend itself inevitably will cause a buildup of melted material that when it hardens will form a blockage and cause the filament to become stuck. The next thing that happens after a blockage is that either the motors are skipping steps or the drive gear will start chewing filament and extrusion stops.
- Place a mark (use a fine permanent marker) on the bowden tubes where they go into the black plastic ring on the heatsink. Then unplug one of the bowden tubes and measure the distance from your mark to the end of the tube. This distance must be 53 millimeters.
- If you find this distance is shorter it probably means there are now a blob of plastic inside the bottom of the heatsink where the bowden tube were supposed to be. To remove this blob, first heat up the hotend to around 220 degree Celsius. Then insert a long 1.5 millimeter hex key (or similar rod no thicker than 1.8 mm) and push the blob towards the hotend as to extrude it in order to get rid of the blob. Also remove all the residue from the inner sides of the heatsink. If it is not possible to push the rod through the blob, it will help to heat it with the flame of a lighter then quickly insert it, let it melt a little into the blob and then quickly pull it out. Usually this technique will cause an amount of residue to be stuck on the rod upon removal.
Repeat the above steps until all residues have been removed and you can clearly feel the rod touching the edge of the diamond hotend at the bottom of the heatsink.
- When the Inner part of the heatsink is clean, take the bowden tube and make sure that the end is cut perpendicular, if not make a clean cut using an exacto knife, then use the permanent marker and set a mark at a length of 53 mm from the end of the tube. Then insert the tube all the way to the bottom of the heatsink and ensure that the marking goes flush with the black locking ring.
- The final step is to lift the locking ring while applying pressure to the bowden tube, do this by pressing down on the bowden tube with one hand while simultaneously pulling the black locking ring upwards (use a pair of tweezers or some other tool that is able to reach below the ring) then releasing the bowden tube. When this is done correctly the black ring will maintain the tension on the bowden tube and thereby ensure that there will never be a gap between the bowden tube and the hotend.
Repeat for each remaining heatsink. When finished, insert filament through all three extruders, all the way to the hotend but do not extrude any filament until all three filaments are loaded. Then verify that extrusion of all three filaments is possible.

Prusa i3 version with extrudate cooling

If you wish the benefits of actively cooling the extruded material while printing with your new Diamond Hotend (especially good for printing bridges and overhangs), we encourage you to browse to http://www.thingiverse.com/thing:720520. There you will find an alternate cooler shield file, this version features a pendant for attaching a 5015S radial blower fan.
1. Download and print �diamond_cooler_shield_blower.stl�, and �bq_extruder_Tobera.stl�.
2. Insert two M3 nuts into the cooler shield blower pendant.
3. Screw the blower bracket in place using 2 pcs countersunk M3 x 10 mm screws.
4. Screw the radial blower onto the blower bracket using 2 pcs M3 x 20 mm screws.
5. Screw the blower nozzle onto the blower bracket using 1 pcs M3 x 15 mm screw.
6. Extend the wires from the blower
Extruder motor mounting

The original Kickstarter rewards for the 1,7 mm filament version of the Diamond Hotend came with optional MK9 bowden extruders. The bowden extruder mounting brackets are printable and is available in slightly different versions intended for a few different printers mounting locations. The printable parts are available on Thingiverse.
- For bq Prusa i3 Hephestos the part "MK9_bowden_angled_right.stl" is used and the assembled extruders are evenly spaced on top of the Prusa i3 frame.
- For other Prusa i3 it is recommended to measure the exact dimensions of the top part of the frame in order to produce mounting brackets with a perfect fit. Edit the OpenSCAD file "MK9_bowden.scad" accordingly then compile, render and export a new stl file.
Assembly instructions for the bq Prusa i3 Hephestos with Stepper Expander - (as of October 2015):
1. Assemble each extruder by placing the small printed part on top of the larger angled part so that the parts align. Put a M3 x 20 mm through each mounting hole and screw them loosely onto the stepper motor. Insert the bowden coupling into the slot between the two printed parts and fasten the two mounting screws.
2. Attach the bowden extruders next to each other on top of the Prusa i3 Hephestos metal frame. Attach a motor cable to each extruder motor. The extruder motor closest to the LCD display connects like the normal extruder as mentioned in the original Hephestos assembly guide (See the connection diagram). The middle extruder motor connects to the second extruder pinrow next to the original motor connection. The third extruder motor cable connects to the pins on the external stepper driver. All motor cables are intended to connect with the black wire upwards.
Please observe that the orientation of all stepsticks are the same throughout the printer.

Микропрограммное обеспечение

For most firmware to support the Diamond Hotend upgrade some changes are required.

Repetier firmware

Since version 0.92 of Repetier-Firmware there is the option to support a mixing extruder. In fact this feature enables the firmware to handle extrusion from more than one extruder at the same time, in effect allowing for true color mixing capability.
Another neat feature of Repetier-Firmware is that when using firmware retraction Repetier-Firmware can simultaneously retract all three filaments, thereby lowering the retraction length needed (to 5 mm or even lower), in turn allowing for a cleaner, faster, more efficient retraction sequence.
Since setting up Repetier-Firmware is out of the scope of this article, you should go have a look at Repetier Color Mixing.
Repetier-Firmware is an alternative to Marlin firmware. If you choose to go with Repetier-Firmware you can skip the next section about setting up Marlin.

Marlin firmware

This slightly modified version of Marlin which can also be obtained via the link from the Download section below.

Настройка электроники

RAMPS

As of October 2015 the bq Prusa i3 Hephestos - Diamond Hotend version is shipped with the original RAMPS electronics plus a Stepper Expander to make up for the extra third extruder driver.
1. Attach 4 pcs adhesive PCB stand-offs to the Stepper Expander and mount it above the RAMPS, inside the fan holder mount, with the screw terminals pointing upwards. Alternatively use the modified version of the fan holder mount that has been made, replacing the PCB standoff's, see Accessories section below.
2. While observing orientation insert one stepstick on the vacant position on the RAMPS board and the other stepstick into the Stepper Expander. (The trimpot on a standard A4988 driver should be closest to the power terminals on the Stepper Expander)
3. Attach the 2x5p IDC cable from the RAMPS' AUX-2 expansion pins to the Stepper Expander pins, ribbon cable going away from either board.
4. Attach one end of the power wiring to the Stepper Expander's screw terminals, the other end to the power input terminals of the RAMPS board (the black wire to - and the red wire to +). If you don't mind soldering your RAMPS board (voiding the warranty) you can mount a 2 pin male pin header to the position marked 12-AUX and attach the power wires from there.
There are other ways of adding more extruders to RAMPS, for some examples see Adding more extruders.

Rumba

If you are using a RUMBA motherboard to control your printer, here is how to set it up for the Diamond Hotend:
1. Link: Wiring of the various parts
2. Install the RUMBA TAURINO driver from RUMBA (scroll down to the RUMBA_USB_Driver_for_Windows section)
3. Move the on-board jumper from "Stand-alone" to "USB Power". See reference image.
4. Attach a MINI-USB cable.
5. If you do not already have Arduino IDE installed on your computer, download and install version 1.0.x from http://arduino.cc/en/Main/Software. For general info on how to upload firmware onto the motherboard please see http://arduino.cc/en/Guide/HomePage.
6. Using Arduino IDE, upload the Marlin (Stable) Diamond Hotend version firmware to the motherboard. If you are using a different printer you should edit the firmware to fit your machine parameters.
7. Move the jumper back to "Stand-alone" position.
8. Set all the microswitches beneath each stepsticks socket to ON position.
9. Mount stepsticks into the sockets X, Y, Z E0, E1 and E2 on the Rumba motherboard. Caution: be sure to orientate them such that the corner pin marked EN is closer to the motor output terminals.
10. Attach the thermistor to the T0 pin header.
11. Power supply wires (12 volt) mounts in the MAIN-PWR screw terminal.
Note: if you are using the BLUE version of the Rumba board and want to connect a display via the EXP1 and EXP2 terminals, be aware that the silk print has those two connectors swapped, so you should connect the EXP1 cable to the terminal labeled EXP2 and vice-versa.
RUMBA output test gcode

Other

If your current electronics supports only one or two extruders but has some GPIO pins in surplus you should be able to upgrade the number of extruders.

Cura

At the time of writing, triple-material slicing with Cura is not recommended. We tried, but the current version (v.15.01 at the time of writing) of Cura only works for dual material printing. However the developers of Cura has mentioned that this will become a feature from the next major version change.
