Hemera extruder ender 3

Time Required. Suggest a time?? As you may or may not be aware the stock ender 3 main board doesn't include a boot loader. A bootloader allows you to connect your printer to the computer and upload new firmware. The first thing that needs to be done is upload a bootloader to allow you to connect to the Ender 3 via USB connection.

Please note the light blue pin bottom left when looking at the diagram connects to the number 10 pin on the Arduino. The colours of the wires do not matter they are just here to highlight the importance of matching the pins.

You will need to install a custom board called a Sanguino board in order for the IDE to send the bootloader and firmware to the board. From now on you should be able to connect the Ender 3 to the computer via the mini USB cable. Download the Ender 3 Marlin firmware Source files. You may find you don't have the u8glib library installed. Download the. If you don't get an error message when verifying the stock ender 3 marlin firmware you can skip this step. Scroll down a bit further and you will find.

The minimum and maximum temperate settings. In order for the 0,0,0 position to be in the bottom left hand corner of the bed you need to enter a Y min offset so that after it homes to the limit switch it moves to the corner of the bed before starting a print. In my case the nozzle was 23 mm away from the corner when it homed so I added In order to make sure the temperature reading is as stable as possible it is important to PID tune the setup.

Only run a PID tune after you have uploaded the new thermal settings to the Ender 3. After it has run through the 5 cycles that were set it will show the Kp,Ki, and Kd values in the dialog box.It combines our market leading V6 hotend with an all new filament drive to form a highly responsive direct drive extrusion system - providing unrivaled performance with flexible filaments. Hemera is also available as a bowden extruder.

You're probably wondering why at the last minute everything that you were expecting to be called 'Hermes' is now called 'Hemera'. Unfortunately, less than 24 hours before launch, we received a legal challenge from a company much larger than us, and with significantly more legal resources.

They objected to us naming our product after a Greek god from the Mycenaean era, as they feel that name belongs to them. Unfortunately, we don't have the time or resources to resolve this through a long legal process and we just want to get on with making incredible extrusion systems.

Please do excuse us if some of the content is slightly less polished than usual, it's been a long hard night. If you see any instances of the old name hanging around please do let us know too. Thanks in advance for your understanding. For E3D Hemera, we opted for a dual-drive arrangement which provides a huge boost in grip over single drive systems.

We are able to push filament with up to 10kg of force. The secondary gear shaft is on a moveable, sprung idler which allows the user to adjust filament tension. All the gears are hardened stainless steel. Look familiar? You may remember this self-cleaning tooth profile in the Titan extruder. We achieve this profile by individually CNC cutting each tooth, allowing us to provide the round-bottomed root, with a tooth that curves upwards to a robust, sharp tip. As a result of opting for an all-metal hardened stainless steel drivetrain, we were able to reduce the size of the gears.

With the drive train being made from hardened stainless steel, we can maintain the operation of the Hemera gearbox. A dry-running system, as we know, means minimal user-maintenance and also prevents filament debris from sticking to a greasy drive train. Fundamentally, the entire extrusion system is just better. We set out to develop a compact extruder and HotEnd system with a reduced part-count.

Hemera is a system of components designed to work seamlessly together as a single product. To achieve this, we have developed a custom motor, based on a NEMA 17 frame, with our own faceplate designs. Hemera constrains your filament like no other extrusion system.

Just look at this TPU print:. You asked to see E3DHermes printing and you shall receive. How did we achieve this wizardry? Firstly, Hemera was designed to be compact which allows us to attain a very short distance from drive-wheels to melt-zone. This has a number of benefits, primarily reducing the length of filament under compression when being pushed into the melt zone, improving responsiveness.

Secondly, we carefully toleranced all the components after the drive gear. These two improvements together mean that the filament has only one place to go - into your nozzle, and that when you apply a force - it responds.

An additional benefit of this arrangement is that there are zero transitions after the drive gears, filament proceeds directly to the melt. The T-Slots on the custom motor faceplates allow for easy mounting solutions to pre-existing machines, as well as providing a more compact, stable platform for printer manufacturers to integrate onto their machine.

Each side of the motor has 4 T-Slots holes.

One side can be used for mounting to the carriage, leaving the opposing face free for mounting whatever you need, part cooling fans, bed levelling probes, or other accessories. As a result of in-depth testing with a hot wire anemometer setup, we have optimised the airflow of the die-cast fins.Time Required. Suggest a time?? Please note that this guide is assuming the use of a fully assembled and hot tightened Hemera unit if you have not yet fully assembled and hot tightened your unit please see: Hemera Assembly Guides.

Mounting a Hemera to a Creality Ender 3 is easy, and we provide most of the tools you'll need. Please note, though, that you should be very careful of the following safety cautions:. Raise the X gantry to roughly the middle of the Z axis to allow you to have good access. Make sure the hotend has been allowed to cool to room temperature before beginning any modifications. This guide assumes the full assembly of Hermes if you haven't already done so follow this link before proceeding.

Do not touch the hotend unless it is at room temperature. If you have recently been printing let it cool down. The carriage assembly should now having nothing attached but its wheels and belt. Looking at the carriage assembly, you should find that the the top two screws have the button head on the hotend side of the mount. The bottom screw will be the other way round with the nylock nut on the hotend side of the carriage assembly.

Using the 10mm spanner rotate the eccentric nut until you get a good tension on the new mount, using a hand to test for play is a useful indicator. Pictured here are shorter cable lengths than you will have, this is for quick disconnect, you do not need to do the same.

For neater cable management have the thermistor and heater cartridge exiting behind the heater block, when you are facing Hermes.

Pictured here are shortened wire lengths for quick removal, you do not need to do the same. Be aware it is possible to crack the t slots if you use screws that are too long and bottoms out. Over tightening also risks snapping the T slot.

You may want to hold your hand over the square nut to keep it in place while fastening the screw. Wrap electrical tape around the connection side of the wires to keep them together.

You may have to do a push and pull motion to deal with the stretching properties of the cable sleeve. Connect the thermistor, heater cartridge heat sink cooling fan and part cooling fan to the board. There are two options here either source some M2 square nuts and reuse the original screws or drill out the holes to slightly larger than 3mm and use standard M3 square nuts.

Alternatively if you wish to use a more powerful part cooling fan such as a 40 x 40 x 20 mm blower fan. The 40 x 40 x 20 mount is fastened using the x2 top mounting holes with x2 M3 x 10 screws. To give the cable bundle some guidance you may wish to insert a piece of filament into the cable wrap to act as a spine.

Use of the natural curve of the fialement will give the cable bundle a suitible shape.

Please enter the code below. Here's my first version of the E3D Hermes mount for the Ender 3. I might do some small teaks. Instead of the stock fan, I use a 40mm blower fan same as the CRS Pro as i feel it does a better job. It is secured to the fan with some super glue or hot glue.

These are the sample part I printed to get ready for my Hemera. The fans are the ones I purchased from e-bay, haven't tested yet will provide update when complete. I agree. I found a model of the Ender 5 mount which I printed.

Here it is next to the mount in this design, I slightly modified to add mote cable support. Here is the link to the X axis design if anyone wants to use it to help modify. It is only attached with 3 screws. I agree that it is not the best mounting. I am not totally pleased with the way E3D designed the mounting. It seems good, but in actual use it is very difficult to use, there is very little play in the depth of the screws. I have broken one of my mounts on the casting. I'm in the process of testing a mount that is one piece printed.

I will be posting a complete package after testing. Do I have to use longer screws? Trying to mount this on a CR S5 and the 3 M3 screws included with the Hemera aren't long enough to make contact with the square nuts to get this thing attached. I printed this a couple weeks ago and the bridging wasn't perfect on the backside of the holes so I printed another with my Phrozen Sonic Mini and the screws still don't reach.

Joined: Mar 24, Messages: 26 Likes Received: 4. The image you show looks like a serious cooling issue. Much better would be to re-slice and have higher fan settings. Layer height is 0. OK, are you sure your fan is running right?

The place the trouble starts is, of course, just where the object starts to have very short layer times, so the plastic is never getting a chance to cool. The fan is running fine The problem does not start where the object starts to have very short layer times, the layer times are identical Here is what the finished object looks like, next to another of the failed prints which has a less pronounced version of the issue: Maybe you are thinking that the raised part of the failed print in my previous picture is a higher layer - it is not.

The raised part is the same layer as the whole of the rest of the print. At the point I aborted the print, the top of the print should be the same height at all points.

In fact, the part being printed is the BLTouch mount for the Hemera, which finished printing immediately before I installed the Hemera, so there is literally hours between those prints I will say though that I think the filament has too much moisture in it, I hear pops Which I don't remember hearing with the old extruder - it's the first filament I bought, but it's the only PLA that I have, the only other filament I have is TPU Which is what I normally print inand that's harder to print, so I thought I would stick with the PLA for test prints I am left wondering though if it was not an issue for the old extruder, why is it an issue for the Hemera?

PS yeah I did print the HangTight duct myself first, but it obscures where I wanted to mount the BLTouch, so I ended up having to revert back to the original extruder and printed a different duct. PPS - I have a print of it running now, and it has gotten past that point with no significant problems so far.

I reflashed the firmware and instead of using BigTreeTech's Marlin fork as a base, I used this one which seems to be using a more recent Marlin build. Dunno if that is what has made the difference or some other factor, but hopefully the problem is gone. So it completed, but it ain't hugely pretty Strangely, the piece that is sitting on it's own on the left was actually a support for the overhanging part of the print on the left of the image - it disappeared mid-print and was off the print bed behind the printer.

One can only assume it got blown away by the part cooling fan? Either that or I have a poltergeist.

Nope, it was a fluke. Subsequent prints are exhibiting the same issue. Or it got picked up by the nozzle, dropped, then blown by the fan.

FWIW, if I ever have tiny bits of support like that I tend to stick a small single layer shape underneath them. Judging by the support on the right of the model in the pic, I suspect your support generation is also being overzealous as that's a perfectly OK angle to print with supports.

It's just me being over-zealous with the supports - for the little extra time it takes, better to be safe than sorry in my book It didn't get picked up by the nozzle as it happened after it had started printing layers above it.

Please enter the code below. Base plate is. So I designed this instead. Tolerances are quite tight so your printer needs to be dialed in well. The extruder is mounted with a reverse bowden tube to minimize filament forces on the extruder.

The BLTouch mount cluld be a liiitle bit closer to the extruder. The holes for the screws attaching the extruder to the plate are too small. Fortunately I found some screws with smaller heads that I could just barely squeeze in. Log in to MyMiniFactory. Login with Google Login with Facebook. Community Prints Add your picture.
