Got my new E3D All-Metal Hotend V4 - (Updated with Mounted Pics) (Page 6 of 9)

I also just hooked mine up today. Haven't had a chance to use it yet.

Making an extended z stop as we speak. I'll post up when I test it out.

As mentioned a few times in the thread already - most have either spliced it into the existing extruder fan power wires, or just ran a new set all the way through back to the 12v power supply.

The PWM on that pair combined with the PID control makes it a little unpredictable though - but doable for sure

Here is the extended Z stop I made. Works well with the E3D.

yay! I'm glad you managed that. Sorry that I forgot to post the photos.

I was wondering if there was a better option available.

to buy a kit.
Aluminium heatsink, stainless steel heat break, Brass nozzle (0.4mm), heater block, 100K ohm NTC thermistor, 12v 40W ceramic cartridge heater, 30mm axial fan, Fan housing (printed ABS), 150mm high temp thermocouple wire, two 0.75mm Uninsulated Ferrules, Kapton tape, and a fixing kit.

costs £39

to buy in spares...
Aluminium heatsink, stainless steel heat break, Brass nozzle (0.4mm), heater block, 100K ohm NTC thermistor, 12v 40W ceramic cartridge heater, 30mm axial fan, Fan housing (printed ABS), silicon wire and heat shrink.
costs £52.45

(no ferrules, no kapton tape for fixing, no thermocouple wires (silicon instead). but  higher price)

to buy the bits that I want to buy.

heat break
nozzle
fan
heatsink

costs £30.45 which seems a little high.

to put it another way.
I want £22 worth of parts removed from a £39 kit. I'm not expecting the kit to come down by a full £22, but I guess I was expecting it to come down by a little more than £8!

Additionally, Sanjay already said that he was offering discounts for developers, I'm asking if having developed your own heat block (where designs are shared on this forum) qualifies you as a developer (worthy of discount) or not.

sweet just got my E3D in the mail today! man this a particularly beautiful piece of engineering! very pleased to own one! i wonder if there is a way to get it to work with the original acrylic jigsaw... that would be neato!

what are these Ferrules?  they are the 2 small metal pieces in the bag with the green wire. they arent included in the instructions..

oh thanks! im gonna want to insulate them afterwards i imagine. for some reason that page isnt loading for me on mozilla or chrome.. weird

I agree always a good idea to have spares - of ANY 3D printing component

But.. I've put over 100+ hours on mine, and not a single issue.  So whilst you may have had a failure - theres certainly no indication of anything other than a single instance failure of your own heater cartridge... Not sure it warrants the 'warning' to *all* E3D Users...

One failure, in a batch of how many hundreds.... Just saying, I dont think its worthy of a headline on CNN, or a full recall, or anything Stuff breaks, and it by no means indicates a repetitive issue ..

After about 40 hrs (and 1.5kg) I got my first serious clog. I used a .3mm drill bit and a .4mm drill bit and fiddled around at 250(C). I was worried at first nothing would break free. Eventually whatever caused the clog broke loose, and then the filament went freely.

I have every reason to believe this was some particle in my filament (10lbs of cheap black filament.)  Notable, at 250C the ABS did loose the hallmark perfect-pullout melting figure of the e3d. Instead, it pulled out with a bit of a string. Perhaps the heat creep was enough to soften the abs a bit at 250C past the thermal break.  I assume with higher melting temp plastics they also soften at a higher melting point, so this wouldn't necessarily occur or be devastating. Also, the filament sat at 250C for a good five minutes, so it's not exactly the same as running *through* the hot end at 250C
