KSGER T12 STM32 V3.1S soldering station

[ygi]

The cement isn't even dry and the tips are shipping out the door lol. The "moisture" excuse is just a bit weird.
Here are pics of the crappy heater connections, if you pop off the endcap you can check them. Some people are able to solder them to fix the "spotweld" & "crimp" - but just look at the black slag and it makes sense what ERROR flashing and beeping is really about. I didn't think solder would stick to the heater wire, I haven't tried that.

I'm thinking maybe the excess cement smeared on the outer side of the wire flacks off due to heat expansion, improving contact with copper core afterward. I mean if connections are faulty, they aren't going to fix themselves over time.

On a slightly related thread, does anyone know if any of the tweezers available on AliExpress are comparable with this base, either version 2.x or 3.x?  Would come in handy from time to time.
Thanks

Tweezers? Link? Start a new threAD for that

I just received a KSGER T12 V3.1S that I purchased through Banggood and it was in their USA warehouse. The price was $57 with 3 tips. I purchased it after being super frustrated with my Metcal station that I was trying to work with at home, professionally I had selected Hakko for work after going round through all the various brands.

My unit has a manufactured sticker on 2021/01 on it so it has been on a shelf for a while, or maybe it was trapped in a shipping container in a port somewhere. The internal power supply is V2.04 with the black solder mask and from the previous V2.05 photos I notice it lacks the P.E. via pad.

I have to say that I am mostly impressed and have soldered a few hundred components so far over a week of time. If I was going to modify or "fix" anything my contribution would be:

• External stand switch like Hakko and disable the rattle switch in the handle. The rattle switch is too sensitive and triggers all the time as I work at my bench.
• Less beeping, I turned it off but if I fix the switch then perhaps it could be tollerated

I think you can change the inactive / sleep timer so that the shake switch would essentially not used.

Hey, looks like latest version also marked as v3.1S does not have battery powered RTC, battery it self is placent on PCB but after reset clock is reset as well.
No idea why but it seams that is by design as it was described on product page that this version does not support real time clock, anyone know how restore this function ?

[Sniper1]

So i am considering geting a V3.1S station or the old V2.1S. Regardless ill follow up with some info about the boards inside.
(not sure if i should go with v2 or v3 but it will be one of them)

Hi.
Did anyone had problems with Ksger loosing calibration settings for different tips ? couple days after calibrating tip, or after couple tips swaps it seems that my station is loosing settings, station reads 380 but im getting 450 (correct tips chosed in menu)?

[DavidAlfa]

Very new tips will change their response after a while, try recalibrating again.

[Dragonisko]

i had to recalibrate same tips couple of time already, im just wondering if that's normal, or there is something wrong with mine station

[DavidAlfa]

That's what you get with $3 tips. They will eventually settle down.
How many hours of use fo they have? If you bought them and used 4 times in 2 months, that's pretty normal.
I've found that on long unused periods they seem to take moisture, afterwards they'll work funny for a few minutes.

[Dragonisko]

most common tips im using got probably around 20-30h usage each, soldering station is used daily for minimum couple h.

[DavidAlfa]

What KSGER version?
No idea if it could be the ksger firmware, never used it, perhabs someone could answer better after knowing the specific model.
I have a Quicko myself, and I ran away from the crappy original firmware as fast as I could 

[Dragonisko]

ksger 3.1 but not on stm32, i was thinking about changing chip to stm and using custom firmware from github.

[Sniper1]

Ok,
so my station was made in 09.22 and uses 2.05 version of the PSU and the green control circuit with the soldered vertical li cell

hi, has anyone taken a look at this new variant of the KGSER T12, with "STC Controller V2.3"? it's marketed as having a grounded chassis and a (new?) display. would there be any disadvantage to using a non-stm32 controller?

If you're just going to use it as it is, µcontroller doesn't matter as it doesn't take much performance to drive a soldering station. It's when you want to use a custom firmware that you need to mind it for compatibility.
Basically, it makes more sens for Chinese manufacturers to spend money in a bigger screen than in a reputable ST branded chip.

[DavidAlfa]

Why is the earything so critical? Takes two minutes to earth any other station.

Is there anything special about the handles for these T12 irons? E.g. this handle is apparently for the V2.1S only, whereas something like this is listed to work with V3.1S and V2.1S

Can you mix/match parts with DavidAlfa's FW? E.g. get a Quicko STM32 T12-958 put DavidAlfa's FW on it and use this handle? Would you be able to mix parts with stock firmware?

[mastershake]

if the handle works for 2.1s then it will work for 3.1 also and the other way around

Yes you can attach any KSGER handle with any KSGER Station that has same number of pins in GX connector.
KSGER Stations and Handles use 5 pin GX connector.
Quicko/Queeko use 4 Pin Connector in their Stations.
You can aslo use them on KSGER after changing Connector and with slight Mods.
