Ironos: iron starts heating although autostart is set to sleep

[discip]

Good evening,

• I'm submitting a ...

  • [x] bug report

• Do you want to request a feature or report a bug?

I want to report a bug.

• What is the current behavior?

The iron starts heating, when it gets powered up, regardless of beeing moved or not.

• What is the expected behavior?

The iron does not start heating, when it gets powered up, while not beeing moved, until it gets moved.

• If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem

Set autostart to S and unplug the iron.
Plug the iron in again and watch its behavior.

• What is the motivation / use case for changing the behavior?

If this is left at its current state, there is no sense in having the option to choose between T and S in the autostart settings.

• What are you running:

  • TS80
  • Firmware Version: v2.08.1
  • PCB Version: 2
  • Power Supply (Voltage and Current Rating):

voltage | amperage
-|-
3.6 - 6.5V | 3A
6.5 - 9V | 2A
9 - 12V | 1.5A

Thank you in advance
kind regards

@Firebie
I tried the attached file, but unfortunately it did not help. :(
The iron still starts to heat up immediately after being plugged in.
Thank you for trying anyway.
I hope you will get this to work as you did with #569.

[Firebie]

I don't have TS80 (I have only TS100), try this:
TS80_EN.hex.autostart.fixes.3.zip

[discip]

Sorry, but this did not solve the problem either.

[Firebie]

Try this:
TS80_EN.hex.autostart.fixes.4.zip

[discip]

Nope, unfortunately no obvious effect.
Thank you for being persistent. 👍

[Firebie]

I am running out of ideas, try this:
TS80_EN.hex.autostart.fixes.5.zip

[discip]

@Firebie
Thank you for your effort so far. 👍
But this one did not work either.
ps.: Even if you don't get this to work, you tried and that is what counts in the end. 🥇
I even lowered the sensitivity to 1.

[Firebie]

Are you sure that the iron is steady during power connection? If it is not, accelerometer will trigger out of sleep behavior.

[discip]

Yes I am.
I even clamped it down to eliminate every possibility of moving. ;)

[Firebie]

We have to call in main developer :-)

[Firebie]

I have a new idea:
TS80_EN.hex.autostart.fixes.6.zip

[discip]

You are really determined! I appreciate that. 👍
But despite the fact that the display now says "Sleeping...", it still shows underneath that it heats up and the tip gets hot as well.
I think you are getting closer. 👍

[Firebie]

During sleep iron uses sleep temperature (150C by default).

[Firebie]

Better try this:
TS80_EN.hex.autostart.fixes.8.zip

[discip]

You finally did it.
Awesome! 👍
I am going to run some scenarios and if everything will work, this issue is terminated.

[discip]

@Firebie
Sorry, but I have to reopen this, because I noticed that the iron starts to heat after a while (1 or 2 seconds) of correct functioning, without being moved, if the sensitivity is set to 6 or greater.

[Ralim]

That's normal if you have sensitivity set high, as its sensitive to pick up the noise in the sensor of the iron itself.

[discip]

And is there anything, that could be done, to fix this behavior, since I need the sensitivity to be 7 for my application. But I can't use this in combination with autostart sleep, because it is triggered way to early.

I just had an idea of giving the autostart sleep its own sensitivity.
Could that be done?

[Ralim]

Having multiple sensitivity levels could be done, but makes the code even more interlinked which makes debugging harder. A different type of filter could help a little bit here, but not massively as some of the accelerometers are noisier than others.

Could you explain more about your use case?
It feels like you a wanting something different to what sleep mode is for...

[discip]

For the most part I am soldering tiny parts and in that case there is not as much movement, so I have to set the sensitivity higher (for me 7 was enough) to keep the iron at its required temperature.
And autostart in sleep mode is just a very convenient way of using the device, because in most cases I do have to prepare things after I plug the iron in, so the tip is not heated for nothing.
I hope I could make my situation clear enough.

By the way: I am impressed and grateful for what you have achieved. 🥇
And I do not take your work for granted.
I just hope to help to improve this already great device.
Thank you so much so far

[Firebie]

2 levels of motion sensitivity (one for autostart - less sensitive and one for general - more sensitive) will not help, as iron will never come back to sleep mode due more sensitive second mode.

[discip]

@Firebie
Good evening,
after your post I was confused for a bit, because the setting: sensitivity = 7 worked flawlessly for me in the past (2.06 RC5). And after positively testing it for assurance just some minutes ago.

My assumption is: Because the temperature is relatively low (approximately 21°C) after the iron is being plugged in (Wich I definitely appreciate! cudos to @Firebie 👍 Please, please keep the behavior of the iron sleeping at room temperature on start.), there is more 'noise'. And later while working the sleeping temperature is much higher (90°C in my case) so there is not as much noise. And the iron sleeps with the sensitivity set even to 9.
So I think the solution would be: To make the sensitivity dependent on the temperature, if that makes sense. :)
Thank you in advance
regards

Try this:
TS80_EN.hex.autostart.fixes.9.zip
and another one:
TS80_EN.hex.autostart.fixes.10.zip

[discip]

@Firebie
Thank you so much.
This is it! 👍
You did it! 🥇
Works as expected! 👍

[Firebie]

9 or 10?

[discip]

Sorry, it is 10.

[discip]

Good evening @Firebie,
would you mind to share the latest compiled build?
Or help me with compiling it myself?
kind regards

TS80_EN.hex.autostart.fixes.11.zip

[discip]

Oh thank you so much.
It works as intended, buuuut ...
the scrolling description unfortunately is missing the newly added 'O-parameter '.
