CFW for KSGER/Quicko STM32 Soldering Stations

[sst311212]

About the C210 issue, no idea, it's connected in the same way as T12, but the output is much lower, about ADC 1500 for 400°C.
Try a manual calibration in CALIBRATION > SETTINGS.

Tip will heat up when adjusting default cal250 value in calibration setting menu.
It's no sense that you need to insert tip first when changing default cal value, or maybe these settings should move to iron menu.

Yes, it's connected as the T12. But in calibration process... it glow like a nice red bulb and burned out... 
So i was thinking if i copy the fw from a same version pcb already calibrated with the C210, maybe no need to calibrate again.

You can dump chip's full data(ADDR:0x8000000 SIZE:0x20000) from the old one and write it into new chip.

I used this calibration method. Can't calibrate without the inserted tip.



Is there a way to erase the chip's content? It has the original Ksger fw, can't read, can't write, can't erase...

Or the only way is to replace the STM and program it as i wish?

I am using the JBC C210 tip in this configuration on KSGER 2.1S board, with 12V power supply.
Same way the T245, but with 24V power supply.
Green wire not connected.

[DavidAlfa]

Are you even reading? I said to clear the option bits.
This is explained in the programming Readme.
Same as why you need to insert the tip, also explained in the operation manual.
Guys, don't be lazy and read!

[cosmin1]

No need to argue, i don't know what option bits you are talking about.
I am using the original firmware, not yours. With yours i get checksum error and continously restarting.
The meaning of the forum is to ask what we don't know.

I finally succeeded to erase the "locked" MCU.
But no matter how i try, the fw copied from the other MCU is only 4kb... So not working when i upload in the new MCU.
The original file is 74kb and working. But i still have the calibration problem.
So... in the calibration process the c210 tip is turning glue red. I can't calibrate him without burning out. Can anyone help me out with this. I tried to calibrate without the tip, but did't help.

[DavidAlfa]

Then you have a fake/clone! Newer firmware uses different features which unfaced lots of fake stm32!

Option bytes unlocking and fake device detection are described in the programming section:

https://github.com/deividAlfa/stm32_soldering_iron_controller/blob/master/Readme_files/Programming.md

But no matter how i try, the fw copied from the other MCU is only 4kb

Because when reading with ST-Link you must set size to 0x20000.

Greetings.
I have a ksger 2.1S board with an old handle and a 5-wire cable. I want to change the handle to a more comfortable one, but the new handle has 3 wires. Is it possible to adapt the new handle to my board?
Thank you.

Thank you.

Handle with 3 wires can be used without NTC or with NTC placed in a connector (not the best solution but ok for 3 wires).
If you want to use vibration switch it is possible also, but in such case heater ground and tip ground should be connected together.

[zalvis]

Understood. Thank you.

Hello David! I installed firmware 1.13.8 on my stations, everything works fine! It’s very good that the choice of station operating mode in the menu is back, it was sorely missed! In my plans I want to assemble a station that operates in two modes - c245 and t12, that is, at the station itself it will be possible to connect both handles, and the choice of operating mode will be carried out in the menu. From this I have a question - saving the calibration data of the tips will only be for one mode or will it be for both?
P.S. Maybe you remember I once complained to you about the fact that my battery was draining very quickly and that the new firmware version was not always installed correctly? The problem was solved by replacing the bluepill board on my custom station with a board with the original chip and everything worked like a Swiss watch! Also, at a sale on Aliexpress in the official ksger store, I finally bought myself a T12 station version 2.1 with an LED display (replaced the display with a white one, installed a mercury bibrosensor in the handle and installed an LED to indicate the operation of the handle) and, of course, immediately installed your firmware during installation There were no problems, everything works great!
​

[DavidAlfa]

Each profile (T12, C245 and C210) can store 85 tips concurrently, changing between the different profiles won't affect the others.

People with those fake/clones that worked well in older versions but failed with the new settings storage:
Please try v1.13.9a, hopefully the issues will be fixed by now!

[ststefanov13]

To David:
Firmware modification allowing automatic determination of profile T12, C245 and C210 according to the type of handle of the Soldering Iron, obtaining an accurate resistor 10k, 20k, 30k or other values ​​up to 100k in series on the NTC sensor in the handle and defining the resistor for each profile. This will allow the profile to be defined according to the chained handle. You already have a procedure for automatically determining the NTC 10k or 100k

An example of an additional precision resistor:

0k = T12
50k = C245
100k = C210

Each of us can exchange NTC for 10k.

[DavidAlfa]

This seems a mess to me, sorry but no, there's a mix of handles coming with 100K, 10K NTCs, plus the tolerances.

[ststefanov13]

100% of the handles for C245 and C210 are without NTC and have a three-wire cable.
They are being reworked to be NTC and five wire cable anyway.

Sorry for my English (using the translation).
Ksger v.2.1, C245, firmware v1.13.9a.
When turning on, the temperature grows by +60 degrees
above from the installation (awakening +30) on all 3 my tips.
Then it decreases to installation and holds.
So it should be?
Cold Boost is turned off, I did not notice changes.
Reset away, installed
PWM 3x, Kp - 40, Ki - 55, Kd - 25
It became above +15 degrees.

[DavidAlfa]

First: is it calibrated? Default values are pretty low, so the controller will easily overshoot.
If It overshoots +60°C for only 1-2 seconds and it quickly returns to normal, it's likely to be noise or a crappy tip, poorly bonded tips from AliExpress will overshoot very easy because the heater isn't well attached to the tip.

Power of C245 must be limited to 120W or so.
Try reducing Imax to 0.5

[xake]

@DavidAlfa, Thanks for the answer, you are doing a great job!
1) not calibrations, there is no good thermocouple, the solder begins to melt by 205 degrees (I do 250 must be reduced by 20 degrees, by 400 don't be changed)
2) yes, temperature exceeds +60 ° C for only 1-2 seconds and it quickly returns to normal,
the tips with AliExpress of course
3) Pmax = 105W installed

KD = 30 almost solved the problem: +15 has become now

It is also planned the handle T12, and therefore the question:
I can't understand how to change the "profile", in the main menu it is not

ps: version 1.13.9a KSGER_v2_OLED.zip in menu writen 1.13.7

[DavidAlfa]

Have you read the operation manual?

[xake]

Have you read the operation manual?

sorry
"Issue a clockwise drag-rotation to show the tip selection." - google translates this phrase very poorly
"Click and hold and turn clockwise encoder" - so better translation.

[DavidAlfa]

the tips with AliExpress of course

Aliexpress C245 perform terribly bad, cheap T12 do better.

"Issue a clockwise drag-rotation to show the tip selection." - google translates this phrase very poorly

This is properly explained in Basic Controls:

For some actions you might be instructed to issue a Drag rotation.
This means clicking the button (Helding down) and rotating at the same time.

Hello David!
Today I used the KSGER_v2_OLED soldering station, FW v1.13.9  05.03.24.
Some settings are selected in the Menu:
Wake mode   STAND
In stand   STBY
Delay      15s
After installing the soldering iron in the stand, I pressed the encoder twice to turn off the heating. The transition to SLEEP mode has occurred.  However, after the expiration of the Delay 15s, STBY mode turned on again. 
If you have the time and desire, please fix this issue in future releases. Thank you. 

[DavidAlfa]

Is it in shake or stand mode? Will have a look at it.
Edit: Sorry, I read it in a hurry, my question was stupid ...

[Polf]

Stand mode.

[DavidAlfa]

You have stand setting = standby, right?
Stand mode didn't check whether the new system mode was a higher power mode, so it now checks for this and ignores it when necessary,  avoiding this issue.

Fixed in v1.13.10.

[S_older]

I'm drowning in information. I could really use some guidance.

1) Of the different versions, which is more preferred? There are quite a few slight differences between brands/models. Thanks to the documentation on github it does give me some ways to identify different version.

Since they all seem to fall into primarily two version; 955/v2 or 958/v3, which should I go for?

2) My plans are to start with T12 tips and then if I get more involved and can justify the cost, convert to T245 tips. But I would like to continue to be able to use T12 tips. I assume I may have a few different types of T12 tips while only having maybe one T245 tip. So I would like to switch back and forth. Ideally whichever model is easier to do the mods on and switch between handles the better.

3) I can't seem find information on if stand sleep detection can be made to work for the T245, if the hardware supports it and if so what modifications might be necessary to make that work.

This will my first legit soldering iron, after using a crappy old school plug directly into the wall with a little knob on it version for many years. While I don't do a lot of soldering I would like to think having a much better station will encourage me to do take on additional and more challenging projects.

My board KSGER v2.1 works with C245 and T12
