the issue with 210 soldering iron reshon by moving the department describing the part of exactly 210 soldering iron to iron.c a few positions higher, that is, all the soldering irons are indicated there in turn and I just changed their sequence and like a miracle 210 would come to life but ..... stopped working 245  and tweezers 120, who may have come across this or have some thoughts on this matter, I will be happy to discuss it, and this is 1000 percent software problem because everything has already been rechecked
My issue was hardware one, at least you can try  re soldering Q2 driving circuit also.

Hey guys I finally found the time to continue on my Unisolder.
I wired up the Power and Data between Front and Back and pluged it in for the first time,

The display shows something, tho its very distorted.

I used this exact OLED:

I used the original Firmware from this post 1 in this Forum.

Cant see this in the Photo, but the upper Bar with "0W 0C" is actually racing from right to left very quickly.

Does anybody have any tips on what went wrong?

It's obviously the same problem as described here:

Seems like your display uses a SH1106 controller (even though it is falsely sold as one with a SSD1306 controller). There is a patched original firmware to work with SH1106 controlled displays:

I flashed the firmware for the SH1106 Display and now the display works fine.

I tried to calibrate the Station, but cant get the R Value to even close the value i need it to go to.
I have a 10Ohm Resistor between SenseA and Vout1-, but the Poti just changes the value from around 30-40

The Calibration Menu says following:

ID: 25 25
CURRENT: 0 128
ADC: 20
R: 40
ROOM: 22

I tried to resolder Q2 Q8 Q10 Q11, but this changed nothing.

Is it a precise 10 Ohm resistor (0,1%)?

If it is you may want to try to fix this problem as described here by 'sparkybg':

Yes its a 0,1% 10ohm resistor.
I check what resistors i have lying around here and try this

Here are some photos of front and back PCB, maybe you can spot something thats not right. I checked the soldering and it looks fine to me.

Are there any points i could measure to maybe get closer to which part of the board is failing?

D18, D19 wrong diodes installed, marking A11 MMBD1501A.
Yep you are right. Impressive that you made that out from this little marking on the diode.
Ordered the right ones and hopefully it'll work then.

Thank you very much!

Hello everyone! I know this may be a repeat question, but I keep seeing conflicting information online so I thought I would just go straight to the source...

For the JBC C245 cartridges and handle, how is the heater and thermocouple connected internally to the outer three contacts? And what is the pinout on the connector for the handle?

I can't seem to find two sites that having matching information for this. Any help would be much appreciated!

Matt
