CFW for KSGER/Quicko STM32 Soldering Stations

[ygi]

In the US, you have hakkoUSA as a branch office of the brand itself. They most likely set their own pricing for the US market. Hakko doesn't bother in the EU so it's down to random independent "partners" importing the goods and asking the price they want.

Anyway, the one you want is FX951 and its price stings even more.

Tell me who has a T245C handle from AIXUN, is this part made of aluminum or stainless steel?

[celica]

hello i have this version of ksger https://github.com/dreamcat4/t12-t245-controllers-docs/blob/master/controllers/stm32-t12-oled/v2.1s-and-Ve2.1S/r2/back-low-res_mods_for_JBC-T245.jpg
i have 3 wire from my handle  how i can make working the jbc245 , i have this screen and i cut r11 make a bridge
when i try to turn it for geting heat it s  reseting
i m making something wrong ?

[DavidAlfa]

Read page 134. C245 consumes a lot more power than T12.

[celica]

it s getting so much hot , tc is not working , need to take off ntc sensor ? an pmw is ok to x1 ? i have 24 v psu !

[DavidAlfa]

Are you 100% sure the GX pin you isolated by cutting the pcb is really isolated?
If It goes out of control, check the MOSFET, it will get damaged easily and get shorted if you made any mistake in the wiring, thus powering the tip all the time.

Enable debug menu, enter it and set  it to 0°C the tip shouldn't get warm at all.
Then you might try some low value, like 50°C.

It all might be caused by the calibration not done.

[celica]

i make this on the picture

[celica]

it seem to working now  at 50 degre i can melt solder , tip at 0 its not working , 50 yes
what is the other step to make it working ?
at 55 i get 400 degre  , something is not good but its not got more far stabilized to 400
if i try to get calibrated tip go red to much worm

Tell me who has a T245C handle from AIXUN, is this part made of aluminum or stainless steel?

It's stainless steel.

[DavidAlfa]

Something seems wrong with your wiring or innthe board modification, getting 400°C when setting 50°C is just too much.

[celica]

i get it good now , i make a mistake from handle connection invert some wire
i get  cal 250 to 2500 , cal 400 to 3880 , it is good ? i dont undestand how manage zero set , i put 45 W power , heater 3ohm , adc time 150 ms , pwm mult 10x , no ntc menu  .
thank you to make a this firmware its realy good , i will buy another ksger solder

[DavidAlfa]

Consider contributing to this thread by nicely describing how you finally did it, so it helps other people with your same board .

That's a much normal value, yes
C245s are rated for something between 80 and 130w, you can raise the power limit quite a bit, 45W is very low and won't get the full potential from these tips.

Zero cal is to remove the amplifier error.
I might rename it somewhere on the future, I chose a simple short name for it, ”Amplifier-induced offset calibration” doesn't fit  .

As stated in the manual, enter calibration menu, insert a completely cold tip (At least 15 minutes OFF), click Adjust, click Zero cal, it will show ”Sampling”.
You will see some value there, if low (0-50) then can be omitted, but some stations (like mine) have it way higher (350), introducing a considerable error.
Click again and it will freeze the reading, now showing "Captured".
Click 'Save" to store the offset value.
Then it's better to run calibration process again for best accuracy.

[celica]

Other things i have 2 wire to go inside the case for standing the handler  , how i can to connect it ?
how i can select tip ? for exemple i have 3 tip i add the 3 with cal 250 and400 ? have a automatic selection ? 

[DavidAlfa]

Have you read the manual at all?

[celica]

yes i just find it for selection tips long push on the tip selection  , by the way ,about the 2 wires from this stand  , i think one is for standing sleep other i don t have idea .

[DavidAlfa]

Then you also read you must disconnect the shake wire, then route it to the stand, in a way the signal is pulled to ground when placing the handle.
A simple switch will do it. Search "stand" in this thread, it's been discussed infinite times.

Hello!  I have a ksger v3.1s soldering iron, I changed the chip to 32stm and flashed a new firmware, connected the c245 handle, and burned the 4409 (BA2K05) chip the first time I turned it on. Tell me what is my reason?  I probably mixed up the red and blue wire of the soldering iron?

[DavidAlfa]

Check the resistance:
 5-4 must be ~3ohms.
 2-4 should be ~0.5ohms.

Of course if you put them wrong, the transistor will overload and burn.

This was your modification, right?

[GREK]

David, thanks for the help, I mixed up the red and blue cable. Yes, I modified the board, cut the track in one place and put a jumper. I saw the version of this board discussed earlier.

[agrifurb]

I Have this board. KSGER. it had the MM chip on it, I have changed it out for a 128K STM32.
I have loaded the V3 KSGER binary, but all I get is a blank screen.
Does anybody have the correct binary for this board please.
Thanks.

[DavidAlfa]

V3 should be the correct version for it, make sure there're no shorts, solder can easily make hidden bridges under the chip.
Did you extract KSGER_v3_OLED.zip and then flashed the .bin, right?
Not the first time I get asked... For this very same mistake...

[agrifurb]

Thanks for your reply David, Yes, I flashed that bin file, and I can confirm there are no shorts between the pins.
If I power on the unit while keeping the encoder pressed, I get a full screen of snow. It goes off when I release the encoder.
Power draw is 34ma.

[DavidAlfa]

Snow/artifacting is usually a bad connection, make continuity tests between the oled and the stm32 pins.
That board uses the problematic linear regulator that tends to fail, check the voltage, If you have a scope it would be even better.
Try feeding it with the stink, connecting only 3.3v and gnd (Do not use the station psu).
Also try flashing the original firmware, available at Github.

Hello David.....
Thank you so much for your efforts on this awesome cfw.

[AWAIS91119]

My english is not so good sorry for that
I was trying differnet things on my board....just for curosity.
When i read the original firmware i saved it and uploaded yours firmware. It worked then i uploaded original that worked without any key.
Then i replaced the mcu (STM32F103CBT6) with another.. and uploaded your fw that worked ....after that original firmware also worked ...but when i removed the eeprom then original firmware asked for key....your worked without any problem...
How original fw works...i mean without eeprom what happens that it needed a key .....i have read the forum many posts of yours .. but one thing i want to ask is when i flashed the mcu so many times it did not asked for any key...
Can u please clear my mind....
Btw i am using your firmware ...i dont need original.....just learning
