Here is what I re-measured on the connector with an inserted (used) C245 cartige a moment ago:
Pin 1 to 2: 2.9 Ohm
Pin 2 to 3: 1.0 Ohm
Pin 1 to 3: 2.9 Ohm
With no cartige inserted I have no connection/resistance between any connector pins.
David, the HANDSKIT uses a different arrangement of the GX15-5 connector. See my last picture.
H is the thermocouple, T+ is Plus on the soldering tip, SW is the vibration sensor, GND is the signal ground, PE is the protective ground. With the Handskit, the NTC is soldered to the board.
That's how I did it. My GND is PIN 3.
My measurements 1to3 and 2to3 seam to be okay. The only strange thing is that I measure about 2.9Ohms from 1 to 2. That should be around 2.9 + 1.0 = 3.9 Ohms if I'm not wrong?Here is what I re-measured on the connector with an inserted (used) C245 cartige a moment ago:

I measured it multiple times, but will re-measure once I'm back home.
EDIT: I just realized that I probably wired the thermocouple and heater the wrong way around. According to this...David, the HANDSKIT uses a different arrangement of the GX15-5 connector. See my last picture.
H is the thermocouple, T+ is Plus on the soldering tip, SW is the vibration sensor, GND is the signal ground, PE is the protective ground. With the Handskit, the NTC is soldered to the board....I should measure the 1Ohm from PIN 1 (marked H on the board) to 3 (marked with ground symbol on the board).
And 3 Ohm from PIN 2 (marked T+ on the board) to 3.

What is the function of the 10 ohm resistor in the picture on power supply ?
What is the function of the 10 ohm resistor in the picture on power supply ?
This is a revision of my power supply. When using 245 (when the soldering iron tip is cold), the power supply went into protection cyclically.
If you use T12, then this is not observed.
Changed the parameters of the current sensor. On the factory circuit, two 0.43 Ohm resistors are in parallel.
I added another 1.0 ohm resistor. And the power supply stopped going into protection.
Perhaps other instances of Handskit power supplies will not have such a feature.
Does the tip change feature work in version 1.10.2?

!!!! Signal Ground is not connected with Protective Ground on the board. !!!!
pin 1=RED=Theromocouple
pin 2=BLUE=Heater +
pin 3 bridge 4 = GREEN = Protective Ground
pin 4 bridge 3 = GREEN = Signal Ground

[...] better to solder a led or a 1n4148 there to clamp the voltage at lower level than VCC.
Please document a bit the steps you took to make it work, so everyone with the same board can have a look at it.
Was it the gain resistor?
- Increase Pid Ki until having too much overshooting/oscillations.
- Reduce tip filtering to 30-50%.
- C245 sensor output is much cleaner than T12, try lowering ADC delay to 1ms and ADC time to 50ms, it might work nicely.
For convenience, it enables the tip selection for 5 seconds after changing a tip, so you can chose the new one by rotating the knob, or simply wait the timeout for it to go away.
Don't go Superman, it will ignore it if the tip is inserted again in less than 3 seconds, assuming it was a a connection failure instead.
Yeah, I have to update the Operation manual, too busy...
