Hi,
Can anyone provide instructions on how to convert KSGER 2.1 station to support T245 handle?
I have attached a photo of my board.

Thank you.

cut r11 trace

cut r11 trace

Ok. Is this correct? Where should I connect TC+, to NTC?

wickated · « **Reply #2578 on:** January 06, 2022, 12:40:49 pm »

watch the trace nearby r11 and ull see special pin dedicated to jbc tc+ (lowest in 6 rake)

T12 has heater and thermocouple in serial.
That trace that you need to cut is to split power (+24V) and input of U3 amplifier (this is to know what is the temperature on the thermocouple).
I hope I explained it clearly. If not, just ask.

So you need to connect TC+ to JBC (also where is says: "this trace wrong on some boards"). So your thermocouple will go to R12D (pin 5).
Everything understandable?

EDIT: I guess I was a little bit too slow

This is the C245 connection

Understood.

I guess I have to also replace original 75W power supply with something bigger, like this one:

I don't think you need it. At least you don't need it from the start. You can use your current PSU. You just have to go into settings and limit power.
David, am I wrong about this?

DavidAlfa · « **Reply #2583 on:** January 06, 2022, 09:07:35 pm »

Meh, the cheap 75W rarely handles that, usually it resets or greatly reduces the voltage.
Try it, if it goes bad then get a better PSU.

There's a new model, the T12-959, with 2.6" LCD.
It seems to use stm32 but I didn't find any board pictures.

one of the ones i received that looks like that one has an stc not stm on the board

ygi · « **Reply #2586 on:** January 24, 2022, 07:16:21 pm »

It's actually written on the product page:

Using STC15W408A5 microcontroller,
Use sGM855xN high precision op amp,

DavidAlfa · « **Reply #2587 on:** January 24, 2022, 08:55:05 pm »

Ouch, how did I miss that in the description?

These say stm32, but they also say it's OLED. I doubt any is actually true.

STC (Now?) has english datasheet and website:
https://www.stcmicro.com/stc/stc15w408as.html

Seems a basic 8051-based MCU, only 8K flash and 512B RAM.
But has enhanced execution times, much faster than traditional 8051.
Up to 35MHz, that gives more than enough processing power, but the memory is definitely very limited.

ygi · « **Reply #2588 on:** January 24, 2022, 09:39:06 pm »

Yeah, it seems very unlikely that someone would make a clone on a completely different microcontroller and bother recreating the same firmware. Most certainly they are all using STC.
Now, that chip may be enough for its purpose but that's a definite rock bottom downgrade for anyone wanting to hack it.

DavidAlfa · « **Reply #2589 on:** January 24, 2022, 10:09:36 pm »

Hmm and the Quicko T12-958 seems to be a KSGERv3-compatible.

If anyone needs T12 tips, here is the pack of it for less than 20€

vulkan over at dangerous prototypes put the unisolder into the ksger style case as a lite version now looks like

Hi,
Can anyone provide instructions on how to convert KSGER 3.1s station to support T245 (C245) JBC handle?
I have attached a photo of my board.

HELP

wickated · « **Reply #2593 on:** January 26, 2022, 10:50:00 pm »

cut at x mark. solder at bolb mark

DavidAlfa · « **Reply #2594 on:** January 27, 2022, 12:23:42 am »

Then follow this connection.
Edit: Also added pcb picture just to annoy Wickated

noone complaining bout FW ? im still on like september build and feels ok.

DavidAlfa · « **Reply #2596 on:** January 27, 2022, 12:58:54 pm »

There aren't big changes, just minor gui bugfixes you'll rarely encounter.
The settings structure isn't changed, you could update right away keeping everything.
Just in case, make a backup of the flash...

luqash · « **Reply #2597 on:** January 27, 2022, 01:28:43 pm »

ma soft suck...
standby time (manual option) minimal is 1 minute....

luqash · « **Reply #2598 on:** January 27, 2022, 01:32:38 pm »

How I can change soft?

my processor is MindMotion MM32SPIN27PF not stm32...

luqash · « **Reply #2599 on:** January 27, 2022, 02:52:27 pm »

Stlink cant read processor…
I connect 3.3v gnd swdio swclk and cant read
