EDIT: It looks like the Ultimaker thermocouple also uses an M3 thread. I just need to find out where they source their thermocouples...

Shenzhen. Any sort of electronics parts you could every need or want can be found in the markets there at prices much better than Alibaba or Taobao.

Eric: Those pictures you posted above really help with understanding the different zones in a hot-end. What would be the best set up (using the pictures from above as reference) to ensure no jamming or other common hot-end issues?

The Megatronics board from RepRapWorld has got 2 thermocouple inputs. That's also where E3D's adapter board and thermocouple originates from, seemingly.
About the additional costs of thermocouples: that's also bugging me, but I think the best solution would be to have a way to choose during purchase. People who are willing to put in more money can while the ones who like thermistors more are equally well served.
The Ultimaker thermocouple is custom-made if I remember correctly. Don't know about the cost of doing that, but they are generally selling stuff with quite a markup.

I'm new to reprap so I would like to ask if hot end have same function as megatronics board.

Yeah, newer controller boards are starting to support thermocouples. Later on, will try to offer thermocouples as an optional add on, with an additional optional add on of an extension board for people who do not have thermocouple capability built in to their board.

I've got a Panucatt Azteeg X3 controller with the expansion board. It supports thermocouples, but there's zero documentation and my requests for info on implementation and how to set it up in firmware have gone unanswered...
I'm looking for someone with some info on how to implement.

I agree with Greg. I am not sure sure if you are talking about the the City or an online marketplace. I live in Toronto, Canada so I don't think it would be practical to fly across the world to hunt for some thermocouples in the streets of Shenzhen

You asked where to get them. It's up to you to decide how.

Lol, I just wish there was an easier way...
Then again, another option may be a higher temperature thermistor. The PICO guys on Kickstarter are now offering a 500C thermistor as an add on for their hot end. This would be much easier to support in place of a thermocouple but I have not heard anything about the specs of this thermistor. If it is an NTC thermistor I imagine the reading would be quite inaccurate at such high temperatures. Besides I have no idea where they managed to find a thermistor that can read up to 500C

Once you get the hang of sourcing overseas you'll find it easy. Here's a small trading company on Alibaba that's a good place to start. I know nothing about them and looked them up when I was making an order from another vendor.
[www.alibaba.com]
A good way to start is by see who has similar items and contacting them about what you want. The messaging software translates fairly well and some places have english speakers. That can get you started.
Another place to look closer to home for specialized thermocouples are process and industrial control suppliers. Digikey and the like have regular K type but the instruments specific to process control, like the threaded thermocouple are likely best from a specialist.
A quick Google turned this up for a high temp thermistor [www.shibauraelectronics.com]
The info is out there, it just needs to be retrieved.

You might want to ask the E3D guys about the 500°C thermistor. IIRC, they also found one for a reasonable price or something like that.

As for the high temp thermistors I have also found quite a few firms that design high temp thermistors, I just haven't been able to find their distributors

Why dont you just ask them who their distributors are? Typically companies that dont sell straight to consumers will tell you who sells their products.

Hello Eric,
I have a couple of questions about the hotend. What type of stainless steel are you using for the one piece nozzle? Have you ever used taulman T-glass with it? I would be interested in using this with T-glass because T-glass is food safe and was hoping this was too.
Thank you,
Cameron
