CFW for KSGER/Quicko STM32 Soldering Stations

[nunya]

Hi, can someone help me with connecting a 210 iron to a black V3.1 F103 Ksger board. I have successfully flashed the CFW and my 5pin T12 iron functions great. But when I try my cheapo AliExpress 5pin (3 connected and 2 of them bridged) 210 iron I get a 1Hz clicking sound from the iron. I have tried to cut the bridge, but still the same sound. I have also changed the menu from T12 to 210.
It seems like different boards have different 5pin configuration, and there is also some confusion online because some sees the pins from the back, some from the front, and some sees from the end of the cable, so sometimes it gets mirrored. Some of the pinouts uses the 6 pin Hirose connector instead of 5 pin GX/aviation plugs. I also wonder which pins to bridge, if any on the 210.
I have attached pictures with pin numbers and iron contact points to make everything clear, pin 1,2,3,4,5 (seen from the backside, same side as the cpu) and iron contacts A,B and C. Thank you.

UPDATE: It seems like my problems came from using irons made for those 5V battery driven irons, they where wrongly labeled as C210 and looked the same, just without the plastic insulator between point B and C. My mosfet died violently but after changing mosfet and using the proper C210 irons everything seems to work as intended, at least initial testing went well but I havent had the time to use it yet. And the 1Hz clicking sound went away together with the error msgs.

bridged pins are only needed on boards with autodetecting. you need C for power+tc and B for ground

Hello everyone; I've read most of the forum pages, but I'm a bit confused because there are different types of boards. Therefore, I'd like to thank in advance anyone who can help me with modifications related to the C245 on my controller. The PCB shown in the picture is a v2.1s KSGER . What kind of modifications are needed on the board?

I have a Ksger soldering station. After a small mod I've been using it successfully with DavidAlfa's firmware and T470 tips without any major issues.



Something tempted me to try out T210 tips, so I bought a handle and a tip. From what I read, the pinout for T210 and T470 tips is the same, so it should be plug and play. Both handles are wired exactly the same way as in the image below.



I selected the T210 tip type in the OSD menu, connected the handle with the T210 tip, and my station started resetting! I don't know why. I guess the power supply protection kicked in, or something else caused this, but the tip didn't even get warm.

I disconnected the new T210 handle and turned on the station... it booted up. Okay, so I selected T470 back in the menu and connected the old handle... the station reported 'NO TIP'. I didn't know what was going on. The handle was on the stand; after a while, a reading appeared, but the temperature didn't rise at all. I picked up the handle to check if it was warm... and it was Armageddon... the front part of the tip fell off. It must have reached the temperature of the sun and melted...




I disassembled the station and saw the control MOSFET is shorted, full voltage is going from the PSU to the tip (+ and -). Damn... honestly, I don't know what happened. I would be grateful for any hints.


EDIT: i replaced MOSFET and i get it burn  again :-( i'm out of mosfet for now..  .. there is no short between wires in plug or handle, i did some search and  i fount this post
https://www.eevblog.com/forum/projects/jbc-handle-cartridge-data/
and this:
http://adgd.ru/2021/01/04/jbc-soldering-cartridges-pinouts/
says that C1 and C2 are shorted .. so that what happened actually, they are i check it it has 0.5Ohm.. so it can't be heater + and - connected there so pinout for C210 and C470 is no the same actually.  Please advice

So i guess for 210 "J" and "T+" must be joined  ? right ?

Under normal use, overshooting is high for some reason. In debug mode,it is perfect.
I measured the temp both times and the values shown on the display are correct.
I tried it several times, with several PID settings, but same thing....
Why might these differ?

Cold Boost - Off
C245 tip

With Debug https://youtu.be/GdVtO1dAHoQ

[iktinos]

I used the C210 pin configuration shown in the first picture, and the C210 worked. However, it was giving an error at 450°C during calibration, so I adjusted it manually and disabled the cold boost setting, and it worked without problems. But after using the C245 modification shown in the second picture (the board in the picture is "V2.1s," exactly the same as mine), the C245 worked, but when I tried to use the C210 and t12, the screen froze and the soldering tip glowed. I noticed it at the last moment and turned the power off. Although I'm not entirely sure, I suspect the voltage regulator might be the problem; insufficient power could cause the device to freeze. I ordered a buck converter, and I will install it and carefully try again. If anyone has any ideas on this, please write them down.

I took the KSGER C210 soldering iron.
Does anyone know how to connect the C210?
I tried in various ways, but it always gives an error.

Hi,
The message you linked shows the correct jbc connection.
Yes, you could use one of the gnd wires (3/4) for that.
But you'll have a hard time desoldering that connector!
The easiest way would be to cut the pin, so it doesn't reach the board, then solder a wire to it.
Once you do that mod, you'll have to fix the T12 handle, joining both gnd wires together into the same pin, also T12+ with the pin you'll be using as tip temperature sensing (3).

Another approach, tidier and easier, would be this:
Since the T245 handle has no NTC, you'll have to disable it in the settings, so it uses the internal temperature sensor.
Now you can repurpose the NTC pin with few little modifications:

- Remove R10 so the CPU becomes isolated from the NTC pin.
- Cut the trace on R0 to isolate the amplifier from the tip power pin.
- Join the NTC and temp. sense pads.
- Now use the pin 2 for the tip temperature sensing, all should work fine.

The T12 handle would need to be fixed, disconnecting the NTC and joining T12+ with the pin 2.

Disabling the NTC doesn't make a lot of difference, perhabs some °C, but nothing crazy.

Check out your board schematics.

Hi!

So I've tried this approach (I have the same "black" ksger 3.1 board) and want to use T245-A handle.



I've removed the R10 resistor, cut the R0 trace, bridged NTC and JBC pads on the PCB and wired the Hirose -> GX5 as follows:

Code: [Select]

T245 Hirose                 KSGER GX5
───────────                 ─────────
Pin 1 (GND)             ──→ Pin 3 (E/GND)
Pin 2 (HTR+)            ──→ Pin 5 (T12+)                      <----- that was wrong! Pin2@T245 is TC+, not HTR+
Pin 3 (STAND/Crucible)  ──→ Pin 1 (STAND/SHAKE)
Pin 5 (TC+)             ──→ Pin 2 (NTC, rerouted to JBC pad)  <----- that was wrong! Pin5@T245 is HTR+, not TC+
However, the iron does not heat up. The switch on the iron keeps "clicking" but temperature is not rising. Its in sleep/stby mode when station boots, it shows ~120C temp on (I guess that's target temp, tho I thought it shall be 150C as per settings?) but the iron won't heat up.
Also, when I rest it in the stand, nothing happens (I guess its OK because iron is already in stby/sleep) but when I pick it up, I see "boost" and then immediately the station turns off (reboots). I think there's some kind of short because the bench supply shows massive current spike during boost.

I've tried without stand (plugging handle directly to the station, not through stand) but the result is the same (does not heat up and keeps clicking).

Any idea what might be wrong?
thanks!

I mixed  up TC+ with HEAT+.... 

[regamp]

The C210 tip heats up (glowing) in T12 mode.Has anyone else experienced this?

[DavidAlfa]

Of course. Why would T12, C245 and C210 profiles exist if they were all the same?
C210 thermocouple readings are much lower than T12, by 2-3x times.

[ahmadzaa]

I have changed my ksger T12 v3.1 to tip c245 in 24v voltage, but I want to lower it to 12v which parameter should I change, is it better to keep it at 24v or 12v

[DavidAlfa]

Why are you doing so? 245 tips are designed for 24V and >150W.
You can limit the power, which is ~60W for 245 at 12V.

[ahmadzaa]

Oh yes, thank you, it's better at 24v for a 245, I won't change it to 12v

Hi,

I have a KSGER 3.2 OLED board that I have recently flashed to v1.13.14-fix.

I'm not sure if I've managed to break something after flashing or if I have a config issue but since the flashing I appear to have the an issue with the screen.
The top 4/5 appears to be missing every other line and the bottom part is fine (I've attached photos).

I did have a battle getting the memory fully earsed and I can't remember if I used st-link or STM32CubeProgrammer to get the job done (it reported that it had worked and not errored like previous attepmts).

The stm32 passed the geniune checks along with the memory.

Any help would be appericated!

[DavidAlfa]

To me it seems like you might have chipped a corner on the display...
Try enabling display x/y flip and check if the same area is affected.

[rwell]

Thank you!

Flipping X / Y results in the same area affected, so I've chipped a corner 

Are there any recomendations for a replacement display or do I just need a SH1106 SPI display? I see quite a lot on Aliexpress mounted on a PCB, would it make any difference if I were to buy one and remove it from the PCB?

[DavidAlfa]

It shouldn't, as long as is based on sh1106, ssd1306 or ssd1309.
