CFW for KSGER/Quicko STM32 Soldering Stations

[Wsander12]

My question is this. Is the hakko t9 tip for the hakko fm2023. The same as the t12. Meaning could you use one t9 tip on these hakko clones. I could get my tweezers to work on two units one unit for each side of the tweezers. But my concern would be would the t9 tip work the same as the t12. Is there any difference between the tips other then size and dimensions. I don't mind running two stations for each tip. As long as it's compatible.

I did the calibration, and the measurement calibration results are (...)

I did this on mine (T12 tips)
Setpoint / measured
200 212
250 250
300 299
350 356
400 398
450 444

As you see, adding more calibration steps would be pretty much useless.

Can anyone using JBC tips perform this test?
And if you used AliExpress JBC knockoffs before, kindly explain to anwfeb how terrible they are compared to genuine tips!

those are some new type of calibration? (im still on 21y build)

knockoffs jbc get +100-150 C on same adc settings as genuine

[DavidAlfa]

No... Same as always.

Hi, I just received the KSGER T12 3.1s.

The chip is not STM32 but MM32SPIN, how bad is this?

Also I noticed the tip isn’t grounded, I think there might be a connection missing from PE on the power supply to PE on the control board?

[DavidAlfa]

Search "MM32" in this thread! 
Yeah you can just connect PE with a wire.

[Chaoticoz]

Did that, all it tells me is that people swap their MM32s for STM32s. My question is what are the downsides of the MM32.

Also the second question is about the not connected PE

[DavidAlfa]

And why do people swap them? Because they are completely incompatible!
There're no "downsides", it just won't work with this CFW.

asupsp700 how to convert this 2.42 inch oled display from spi to i2c to work stably?

[isabido]

Thank you David for sharing your fabulous work. As you can see, I had an original Ksger v3 that I successfully updated to v1.10.5.

Everything worked the first time without problem.

I wanted to experiment with original JBC C210 nibs. Do you recommend me to buy this handle?

Have you done any testing with JBC tips? Thanks and greetings from Spain!

Hi, can't say, every seller at Aliexpress is a bit like a lottery ticket, quality can vary a lot between them.
What I can truly say is to not buy clone tips, they're crap, even worse than $3 T12 tips, only use genuine JBC ones.

Thank you for your prompt response, I wasn't planning to spend the money on Chinese tips, only the original ones. The link I have given you is the handle with the ksger connector. This seems like a good option to you, right? Will I have to make any internal modifications or is the pinout correct? Have you personally been able to test c210 tips with this firmware?

[DavidAlfa]

I use T12, tried C245 knockoff for a brief period of time (Terrible ***) , never tried C210 myself.
I'm pretty sure others here  use 210 and worked just fine after calibration.

C210 doesn't need any hardware mods like C245, it's very much like the T12, heater+thermocouple in series, just different calibration.
I guess the handle should right away, ksgers have no "optional" pins for secondary functions, nor different pinout versions.

Personally I'd go with the C245 instead.
The C245 has either small tips for precision jobs, and larger tips for heavy stuff, but the C210 have way less power, so not suitable for heavy soldering work.
Also the C245 tips are ususally cheaper, you can get them for 25-30€, while the C210 tend to be more expensive, around 40€.
It's been a long time sicnce I last checked their prices, might have changed.

Hello.

Admiration for your contribution, David! 

I am considering of getting the Quicko T12-955 soldering station and mod it with your firmware to use C245 handle and tips.
Do you think that unit is suitable for this purpose?

They state the the power supply is 120W, which is not enough for full utilization of the C245 tips, but still decent enough for the purpose I will be using the soldering station for.
It can also be powered with external 24V power supply which can unlock the full potential.

I am mostly concerned if the MOSFETS and the PCB traces can handle the higher current.

How much power do you think this board can handle stock and will changing the MOSFETS to beefier ones be enough?

Best regards.

p.s.
sorry if that was already asked.. i searched through the thread, but it's way too long to read all the pages

here are two pictures of the unit taken from the listing

Need to change MCU to original !!!!!! STM32F103C8T6 , STM32F103CBT6  or CKS32F103C8T6 , CKS32F103CBT6  . The thickness of the tracks and MOSFETS is not a problem for the JBC c245, but to fit a larger 1.7 or 2.42 inch display, the 3.3v needs to be modified in particular (SPX2954AM3-3.3). Аnd add 10 M ( 2M2 ) resistor to input of operating amplifier . This power power supply is 80w.

Connect the two soldering tips properly in parallel and you should have no problem. Tried by myself with Handkit soldering tweezers. but the power x2.

So are they straight lying for advertising the power supply as 120W?

The MCU is already STM32 and as far as I can see, the PCB is this one(KSGER v2):

https://github.com/deividAlfa/stm32_soldering_iron_controller/blob/master/BOARDS/KSGER/v2/Schematic/STM32_T12_oled_v2.0.jpg

Do I need to change the display for bigger one?

99% FAKE stm32.

The STM32 has a precise laser-etched label visible well with a microscope.

Sorry for the long answer!  Here are the photos.  I hope you can figure them out.  If anything is not clear, write to dmitriy.kompaniets@gmail.com

To remove image artifacts, I added ferrite rings to the wires... And installed 2 kOhm resistors on the sda ​​and scl display lines...

Have resistor from  +3.3v for reset capacitor ?

[DavidAlfa]

What are you talking about?
Graphical artifacts a are normally caused by DIY PCB designs or using long wires.
Lower i2c pullups will often help, but ferrite beads not much.
Neither it needs nRST pullup, this is internally supplied by the stm32, it would reset itself if it was too weak.
The only cause for a station to reset it's a bad LDO design (Getting too hot and triggering thermal protection) or the PSU getting overloaded because of using a different tip than T12 (Like JBC).

[asupsp700]

Yes, I have. Circled in red...

I wrote for the reset circuit for the screen!

I added ferrite rings because I had them

[DavidAlfa]

Ah, you're talking about the SPI->I2C conversion? In that case yeah!
