I think in practice you can drive the cartridge BLUE-RED OR GREEN-BLUE. It does probably not matter much.
My motivation to choose to drive the heater BLUE-RED is:
Acording to what I think I see in my cross section this is directly over the heating coil. Seems good.
Acording to the schematics...
Becuase mechatronics is my hobby/work and I am curious. I use JBC stations at work and it irritates me that they are so expensive while I think i can do better. Perfect opportunity for a project in my opinion!
Indeed in the connector to the T210 handle there is a blue jump wire between two pins.
Similar jump wire can be found in eg. T115 but between different pins.
I used a belt sander (600 grit) to slowly grind away half while cooling with water and then finished off by hand with 800,1500 and 2000 grit sandpaper on a block!
OK, got you.
Indeed, in theory the resistance GREEN-BLUE should be slightly larger than BLUE-RED..
How is it to measure a thermocouple resistance with a 4-wire resistance meter? Does the measurement get influeneced by the TC? I guess it depends on the internal current source of the resistance...
I agree that your measurements are correct. I get similar result.
But I think the conclusion that only the heater is between GREEN-BLUE and only the TC is between GREEN-RED like the figure below is wrong.
Instead I suggest this (below) configuration.
Your measurements fits this configuration as...
I have not faced any problems with my soldering setup. But I think that if a user uses a floating SMPS there could be problems with not grounding the tip properly. Idealy the user should be able to use any type power source and have the possibility to ground the tip (Connect to Protective...
Thanks!

In this post there is a PDF of a reverse engineered JBC CD-2BC. There you can see how the original connects to the cartridge.
This schematic seem to correlate to the...
Thanks, I see. making self is a big part of the fun!
Didn't know you could not source that MCU, I did a quick search, is this not availible in turkey ? https://tr.rsdelivers.com/product/stmicroelectronics/nucleo-g431kb/stmicroelectronics-stm32-nucleo-32-development-mcu/1962534
Ok its more than...
Nice to see that you are discussing my project AxxSolder here! And sorry for not writing in Turkish.
Just wanted to say that I believe that what adgd.ru claims regarding the C245 pinout can seem correct if you measure the thermocouple voltage while externally heating the tip, as well as...
Timur Bey, Arduino kontrollü bir akü şarj cihazı yapmaya çalışıyorum. Aklımdaki fikri basit bir çizim olarak konu açmıştım. Özellikle sizin fikirlerinizi çok önemsiyorum.
