Sanjay here from E3D - I manage all the things to do with takedowns of clones and the like. Just wanted to clear some things up and make clear our stance on this situation as I feel like there is some misinformation and false accusations being pushed here. Late June: We released our new cartridge thermistor sensor and associated bits that go with them. There are obvious reasons for stud/cartriby SanjayM - General
Quotebigfilsing The cynic in me says they are finally admitting to all the V6 jamming problems reported in their forums and going with a PTFE lined solution and selling the "combat copies" as a smoke screen. Not really, although there is a lot of online noise about jamming issues almost all of these are resolved through support from us. We really stand behind what we design and sell.

Yeah this is just a cheap knock-off E3D v5 type design. I designed that "fin" in there because I needed the extra small diameter length to ensure the hotend would protrude enough from the extruder to clear the carriage on which the extruder would probably be mounted before the fins got wider and might interfere with mounting. It just looked kind of dorky with being just a straight, un-finned shby SanjayM - General
QuoteI'm not sure that using a screw to hold something down counts as "developing". Pretty much the above. I am the one who came up with the idea when we implemented at E3D, but I don't know that we were the first to do so. Probably not.by SanjayM - General

If you don't know who we are do take a look at our website: We're located in Monument Business Park, Chalgrove, Oxfordshire in the UK. We manufacture and sell high quality HotEnds for RepRaps and other 3D printers, as well as filament and parts for printers. We're currently working on the next generation of 3D Printing extruders and technology. We're currently looking for independent, ambitiouby SanjayM - Jobs for people with RepRap skills
I'll be there with the rest of the E3D gang - we've a stand just on the edge of the RepRap Hub right on the corner so we should be right next to all you guys. We've got some cool touchy feely interactive bits for people to experience different materials and other bits. What do others have planned?by SanjayM - RepRap magazine

Just wanted to wade in here and apologise about not getting back about the 500C thermistors. Basically my conclusion is that they aren't worth it, getting the ADC of an arduino to do the full curve over the (non-linear) range of the thermistor is hard, and leads to dodgy resolution/quantisation, the cost is very high too. By the time you've purchased the very expensive thermistor etc, you may asby SanjayM - General
You could use what's called a wire draw plate, used by jewellers to draw down metal wires by fractions to get to a desired diameter. You can pick them up from ebay in appropriate sizes for very little money.by SanjayM - General
Sanjay from E3D here - didn't see this thread until now! We've had the v6 on M90s for a few months now. All the mounting woes go away if you just pop a washer (I think it was M8 or M6) on top of the heatsink to make it sit a mm or so lower, which means the clamping washers are able to push it up into the extruder. You loose around 10mm of Z height, I can't remember exactly what our final Z-heighby SanjayM - Mendel90
You shouldn't need any extra electronics to run the fan at all! Just connect it directly to the same 12v power supply as you are using to power your printer. No control of the fan is needed, it's just a matter of having it on the whole time - attaching it to the power supply achieves this.by SanjayM - General
Very busy with getting our "next big thing out the door" - but thought I'd just chime in with clarification on tightening. As long as you tighten the nozzle at a temperature that is above the temperatures you are going to print at you're golden. The amount of torque you need is in the order of 3Nm as measured by our little torque wrench - aka not very much.by SanjayM - General
Hi all, Once again - too long since I've reared my head here. Apologies once again. The people that were having issues have been in touch with me via the contact form on our website, and we're working with them to get them sorted. If you're really struggling and think something is wrong with your hotend the absolute best way to get in touch is by the contact form - we almost always respond withby SanjayM - General
We also just got in our Taulman Bridge, and have been playing with it, so here is another video, pictures and commentary of our initial impressions. http://forum.e3d-online.com/viewtopic.php?f=9&t=48&p=229#p229 I'll do a full review with some more substantial prints soon, but in essence this stuff is brilliant.

Patents I'm completely unphased by the whole patent debacle here - we are lucky enough that we know some of the best patent solicitors here in the UK purely by personal connection. I did see the afinia case, particularly the "Thin wall tube" patent. They pretty much laughed at the patent as being incredibly narrow in it's scope - in particular regarding specific dimensions and materials. These diby SanjayM - General
Jzatopa We don't have anything in the way of a threaded plug, however a small printed part is probably going to work just fine, especially if you're using some of the supplied PTFE tube inside to line it. I'll look at getting something CAD'd up for that and stick it on thingiverse when I get a chance. biszkopt80 Greenman100 is right, in that we are out of fans at present.

Hi All, It's been way too long since I've appeared and commented here - for that I apologise. It's been a crazy time here at E3D, we've constantly been in a state of scaling up to meet demand. I can't complain from a business perspective, but it's really hampered my ability to be present in these forums and elsewhere provide support and guidance where needed. I feel in some ways I haven't been aby SanjayM - General
Regarding the hardware - I'm not going to get too specific with things, because it's not ready, and what we do have is a hack of the most dirty and epic proportions. There's so much "I'll just screw this into about here, and cut that till it fits" We don't even have firm dimensions for much of this. Our main objective with this very first prototype was to test/experiment with sealing - our expeby SanjayM - General
Quotejzatopa will you be able to mix RGB or CMYK? Actually we'll need CMYK+White+(Maybe Clear). You don't have the white paper upon which to put your CMYK mix onto, so you need white. While you're at it you may as well add an alpha channel (Clear) and get full colour and transparency. 6 is a nicer number than 5 to deal with from a machining standpoint anyway. So we'll just do 6.by SanjayM - General
I'm really interested in colour mixing. Josh and myself at E3D Online have been working on hardware, and have something that works better than expected, with fast snappy colour changes and producing homogeneous output: http://www.youtube.com/watch?v=vmn7K1U06Wc It should be noted that the long periods of green extrusion are intentional to show the ability to mix colour, as opposed to simply exby SanjayM - General
We use brass because it provides a good balance of thermal conductivity, resistance to the stresses of printing (where aluminium does not fare well), it also machines to a good surface finish which is important for laying down a clean bead of filament instead of sticking to it and dragging it along the built platform. The inherent low surface energy of brass helps here too, as well as helping scrby SanjayM - General
GSM For what it's worth - the E3D hotend is most directly derived from early eMaker (now RepRapPro) designs by Jean-Marc Giacalone (and maybe Adrian Bowyer to some extent) which is a British company. An eMaker Huxley was the first printer I owned and hacked on. That is the place from which I took the concept of a heat-break screwing up against a nozzle to seal inside an internally threaded heaterby SanjayM - General
Regarding the E3D and thermal analysis of CAD - I've done a fair bit of this stuff a long time ago outside of the scope of 3D printing, and I did run plenty of analysis in the design/verification stages. However I am also aware of when these types of techniques fail to produce useful results - this is very much one of them. The real design, analysis and calculation were done on a whiteboard withby SanjayM - General
Very busy right now getting ready to shut up shop for Christmas - just chipping in to say that yes, the thermistor is rated to a max of 300C, and that the 400C figure on the site was done with a thermocouple. Going back and re-reading the description it reads as if the hotend should be able to run at 400 out of the box, which is not representative of reality. I'll get that clarified and changed Aby SanjayM - General

Thinking about what else is produced in those kind of shore hardnesses and the precision they achieve, I agree that my comments about it being difficult to extrude filament with precision are actually unfounded. I'm interested to see what filaflex do for their 1.75mm line, and if it's actually printable.by SanjayM - General
Yep, saw a bunch of variance and things like the filament being oval in cross section. I think it must be extremely difficult to extrude something of this softness with a tight control of tolerances. Your E3D hotend has an internal diameter of 3.2mm, so you should be able to push 3.1mm filament down it. However there is the chance that as your extruder applies pressure to the filament (filamentby SanjayM - General
