Hi JeAfKe,

another very good solution of installing E3D's on the Vertex ! And thank you for Your ethical support ! ;-))

I was out for a while and want just to report of my meanwhile good experiences with 1.0 mm nozzles.
Cause Banggood offers this nozzles with that big opening for their cheap E3D-Klones i use now numerously i decided to test it.

Result: It works great with PLA and ABS, and their flexibe filament-derivates and all fiber-reinforced types but not with Polyamide (the melt is too thin fluid)
With layers of 0.5 to 0.6 mm height and wall thickness of 1 or 2 mm the printing time decreases dramatically !
Of course it does not affect accuracy, boreholes, openings and gaps are same possible as with small nozzles.
And with the infill of 1mm width the strongness of the printed part also increases a lot.

For regular output you should drive your hotend with the 40 Watt heatercartridge. The 50 Watt i use are not an overkill (contrary you can read sometimes ;-))

Conclusion: i recommend it for all bigger parts without the need of details.
Now i often print the details with smaller nozzles, mostly 0.3 or 0.4 mm till down to 0.2mm and glue or screw them to their location.

Does anyone with the E3DV6 know how much material they are printing per second?
For now I can reliably print 6mm³/s with the 0.35mm nozzle, and if you look at the extruder filament speed it looks fast.

I ordered some drill bits and will gradually enlarge the second nozzle, hopefully I can get it to 0.5mm without needing more power for the nozzle.

You can buy a 0.5mm E3D-nozzle at banggood.com in good quality for 1.65 € (shipment included !, three for 1.34 € each)
I use them a lot, also other sizes (0.2 mm up to 1.0 mm). Product ID: 981790 for sizes 0.3 to 0.5

As i knew, deliveries into the EU are free of custom and taxes up to 23.- or 26.- Euro, (i order often in China and the USA, never have had any problem, but i live in Spain ;-))
Quality is same as you see of product photos.

Up to aprox. 12 mm³/s is no problem with 25 Watt heatercartridges with 0.5 nozzle, i use 40/50 Watt for more.

hi, 12mm³/s is a lot of material. That sounds good, as I also have to print a lot of big objects without too much detail. Basically a 24hr print could reduce to ~12hrs if I can double the (constant)feedrate, right?

According to http://wiki.e3d-online.com/wiki/E3D-v6_ ... eman_K8400
The author writes
"The Velleman firmware has some serious configurations flaws when using a E3D v6 hotend. I made some modifications to the original firmware in order to use the E3D v6 hotend on the K8400 VERTEX printer. This version supports only one extruder head."
Hi,
I have order 2 E3D-V6 and will convert during the christmas.

According to http://wiki.e3d-online.com/wiki/E3D-v6_ ... eman_K8400
The author writes :
"The Velleman firmware has some serious configurations flaws when using a E3D v6 hotend. I made some modifications to the original firmware in order to use the E3D v6 hotend on the K8400 VERTEX printer. This version supports only one extruder head."

Does anyone knows the "flaws", and what You must change in the firmware to get dual E3D-V6 hotends working in the K8400 ?

I have found that following should be changed in firmware/repertier but can't find anything about "serious configuration flaws" !!!

Set maximum PWM output for orginal E3DV6 matching 15V vs 12V (if used instead of Velleman std)
Set retraction to about 2 mm, retraction speed ??
Change nozzle diameter
Set the temp calibration (matching Semitec 104-GT2, marlin 5)

Anything more ?

regards

Not aware of any "serious configurations flaws". Runs perfect in double-headed mode since July. Used original heater cartridges from K8400. Purchased 0.35mm nozzles from E3D to match the original size. Retraction is set to 5mm. Further details are here http://www.thingiverse.com/thing:1687914

good morning,
no issues with 2x E3D V6, nor with CYCLOPS or CHIMERA

Runs all fine with the K8400

Best
Frank

A late thank You both for Your reply. I ordered 2 set original E3Dv6. I didn't like any of the available vertex-e3dv6 designs to 100% and started design my own. It took a while. The design in openscad is now ready, printed in PLA and up and running. In the beginning of my print attempts with ABS, I had big problems. Read that heatbed and "no-cooling" should make it. But my prints looked terrible. When I started to use cooling all fall in place. I now printing ABS and colorfabb XT (260C) without any problem.
My design:
Reuse of the K8400 connection board, bolts, radial fan and axial fan.
pros
Individual adjustables nozzles (up/down)
Clamps for bowden cables
Cable holders
Forced cooling of heat sinks ("high" pressure radial fan, w/o leakage against nozzles)
Separate cooling of nozzles (25 or 30 mm fan)
Pretty design

cons
? I cant find any yet

Hi,

it is looking nice--I want to test it, how I can get the file to print it?

best regards
Wolfgang

The 2nd revision of my mount is published here http://www.thingiverse.com/thing:2177331

It addresses the following issues of 1st edition:
- the lower ends of left and right holders were too close to the heat-blocks and could melt
- as the result of printing process imperfections there were several gaps in between things causing ducts to leak air
- air duct openings were not aligned with the nozzles
- there was insufficient airflow/cooling towards bearings located under the print-head
- the wires coming from heaters and thermistors were hanging around X rod and it was not easy to fish them into the long channels of the main thing
- the fan was fixed in the position with sliding-in piece rather than screws
- air was hitting heat-blocks not allowing them to reach temperatures above 223 degrees
- while LEDs looked as a cool feature, they were not very practical due to ever-changing amount of light that hits Raspberry Pi camera. Having stationary LED strips along the edges of the printer is a better option.
- overall appearance/design had issues (at least in my opinion)

Thanks.

Hello,
Last week i’ve made the purchase of the set of 2 E3D-V6 for the Velleman K8400. But i can’t seem to get it working as it’s supposed to do.
I’ve tried printing with PLA 1.75mm.
The questions i have are :

1. Loading the filament goes without trouble, during printing any project there is a loud noise coming from the loader, it seems like that it wants to feed more PLA to the printerhead.
What are the settings i’m supposed to use/ change?

2. When i want to unload the filament, the partical that comes from the heater is alot thicker, which causes it to clog up between the printhead and isolator, the unloaded end that comes from the heater ends up being 45mm long and 2.06mm thick

3. How can i adjust the printarea?
I hope you can help me solve this issue

Best regards,
Ben
