CFW for KSGER/Quicko STM32 Soldering Stations

[DavidAlfa]

Post pictures of the screen! 
I didn't understand too well. Is the reading 13ºC higher, or 13ºC lower that room temperature?

The normal behaviour is to be hotter than room temperature (Usually 35-40ºC)

Not lower, really displayed MINUS -15~14ºC

Then the handle NTC resistor is different. The current NTC look-up table is for 10K NTC.
But I know there are stations using 100K NTC.

However it's really weird that nobody reported this issue before.
I will add a new option to select the NTC type!

Thank you David! I will check it with another handle tomorrow.

Looks like the setting to disable button standby doesn't work.
I have the following settings:
- btn slp ON
- btn stby OFF

but when pressing encoder+left it will still cycle through standby then sleep.

V1.5 on today's build.

On a more general note, I believe the previous PID values or maybe the algorithm were better (I used a 3 days old build before). I just can't calibrate some tips properly, the result is always off by +30~+50°C even though calibration values come out very similar when I retry. Admittedly, I only tried with 2 tips and the second one isn't that bad (within 10~15°).

I can't wait tomorrow and checked it. You are absolutelly right!
One handle (yellow-blu) have right amb.temp, another ("Quecoo") have wrong.
And yellow-blu NTC=7.5K. "Quicoo" have 77K

Button sleep / standby options disable button wake, doesn't affect manual mode. That's how its supposed to be and won't be changed.

yup the handle i have from quicko is the same one you have and its the same way. i just never bothered to change it yet. but the same exact handle in the ksger bramd (with the ksger logo) works like normal for me with the ksger stations.

I switched again to the new pid algorithm again. No changes, same thing.
After tweaking the filter values, it seems to be a lot better. It takes a lot of trial and error.
Filtering too much causes these slow oscillations, but insufficient filtering is much worse, because the nasty spikes will pass to the pid.
I switched the NTC algorithm to the float based. Takes lot of processing power, but it's perfectly capable, accuracy will be much better.
Added the a new submenu inside SYSTEM. Allows to fully configure the NTC.
- Pull-up/down resistor
- Pull resistor value
- NTC resistor value
- NTC Beta value

New builds coming!

Oh, that's a "press to wake from sleep/standby" option then. I thought it was the "press to sleep/standby" option. My bad, thanks for clarifying.

[DavidAlfa]

That's when you don't want the encoder to exit sleep or standby modes. Simple as that.
Same with the Shake input. If you disable both, the station will never wake up! Well, unless you trigger boost mode...
The main screen code is very sensitive, a little change here can affect something elsewhere...
All the recent changes introduced a lot of little bugs that took while to catch and fix. None were worse than simple cosmetic issues.
Builds updated.

No problem, but please, I wrote the manual for something, so  :

[ricktendo]

If you disable both the station will never wake up!

One way to avoid people making this n00b setting mistake, instead of:

Code: [Select]

Btn Slp = ON/OFF
Btn Stby = ON/OFF
Shake Slp = ON/OFF
Shake Stby = ON/OFFConsolidate the menus into two like so

Code: [Select]

Btn Wake = BOTH/SLP/STBY
Shake Wake = BOTH/SLP/STBYThis reduces the menu by 2 items and it will prevent a scenario that would disable wake all together

P.S. you could also maybe use "ALL" or "FULL" instead of "BOTH" (to distinguish between just one option or both options)

Edit: if you did want keep the ability of disabling wake you could add "NONE" to Wake Mode = STAND/SHAKE/NONE and/or to the above menus NONE/BOTH/SLP/STBY

Edit2: Default would be BOTH of course, if you wanted to disable Shake Wake from Sleep you change Shake Wake = STBY and it will only shake wake when in Standby and not Sleeping

[DavidAlfa]

Yeah these things can be easily polished out.

[wickated]

sorry station is currently at 24/7 load so i cant test new builds 

[illiac4]

Is it possible to implement on the first screen an option to select eather voltage input (left up) or the set temp info.

[DavidAlfa]

What? Why adjust the voltage?

[illiac4]

No no Instead of displaying voltage it would show SET Temperature.
Because you do not know to which temperature will the iron rise since you can not see set temperature only if you rotate the knob.

[DavidAlfa]

I don't think it's necessary?
The station stays very close to the setpoint, so it's very obvious.

Edit ok. Did something.
In run mode, the setpoint is displayed in the place where for other modes, the labels "sleep", "standby", "boost" are shown.
Moved the shake activity icon to the botom and resized the power bar.
Also updated the wake options for shake and button inputs: Off, Sleep only, Standby only, All.
Modified the system settings structure, because due the structure padding, sometimes it didn't detect changes when adding/removing variables, bypassing the checksum detection and causing weird settings to be applied.


New builds.
The tip regulation is working really fine for me, the only change I made was the calibration.




Not yet in the latest builds, also added a smooth brightness ramp at boot.
I'm one of these persons who care about the small things


So nobody found the hidden easter egg yet?

Your temperatures seem very well behaved.  I flashed 2021-08-03b and I'm having a very different experience.  Of course, after flashing I did a full reset.  I've attached some pictures of the temperature graph of each of my tips.  They are in order BC2, D24, Ku, C4, and my one wild tip ILS.  I did notice that after changing tips the temperature graph would start going really fast.  I could clear that condition by going into the menu and exiting.  After that the graph was the normal speed.  I haven't tried to modify the PID values from the reset.  Do these pictures suggest how I can get to your very well behaved temperatures?

[DavidAlfa]

Try the 03c I'll upload in a while.
No idea about your issue. I suspect something related to noise but I can only guess.
Will think about it.

[illiac4]

Very nice with set temp. TNX. I am sure I will find some additional things

[DavidAlfa]

This is the 1% of the code that takes 90% of the time!
The internals are mostly rock solid, most issues are in the interface, due the complex user interaction.

Updates:
- Tip selection screen deleted. The label in the corner is highlighted when selecting tips.
- Only remove the tip temperature widget when an error is active. Setpoint and tip selection can be used normally.
- Remove internal lower temperature limitation, now it can work down to ambient temperature (For standby adjustment)
- Graph bug is fixed (it was just the plot drawing timer being erased by the the error screen).
- Only trigger boost mode if it's clicked within the 1st second, ignore afterwards.
- In graph display mode, to allow watching the system response when changing the setpoint, the temperature widget is updated in the background.
  There's a drawback: Boost can only be triggered in numeric display mode.
- And lots of debugging to fix small details and undefined behaviors that could cause display corruption in very specific events.

Ignoring the spikes, what are the real temps in the tip?

Must he a hardware-related issue. I have 10 tips of all shapes, and they all work perfect with the same pid.

I haven't tried the new firmware yet, but I worked with the currently installed version some.  It seems to maintain about a four degree range.  That's for the two tips that I tried.  I'll give the new version a try.

Edit:  I tried the new firmware.  It seems to act in a similar manner.  The actual temperature fluctuates in what seems to be a four degree range.  I'll keep working with it.

thats just grass grown in your display. time to trim it! 
obviously time to change opamp
