Heated bed 2500 Watt + Duet3 6hc

With S.1 or nothing in the config.g the always comes to a warning:
``temperatur rising much slowly than expected. 1.3.C /sec"I mean I can skip the warning and start again. A few times and it's hot enough. So there are 2 options.
S0.1 = heating slow BUT NO warning ``temperatur rising much slowly than expected. 1.3.C /sec"
S1.0 or nothing: temperature rising fast but it comes to the warning:
``temperatur rising much slowly than expected. 1.3.C /sec"I use the button in the web control. I mean I used the configuration tool to setup heater etc.

It is of course up to you if you use S0.1 or S1.0, you need to decide while keeping in mind the speed of warmup (and maximum temperature).
Forget about the warning message for now! -
It's been a while since I have done tuning so maybe someone else can chime in to give you details about how to get rid of the warning message.
Also, if the warning message results in the heater stopping to heat, then there is a problem. Again, I am not the right person to help out with that. -
@jens55
Ok.. but why does it come to a warning when it is faster? The warning tells its rising to slow..
Why does it care about it? Haha
Can I skip this warning forever or change the value for " it's to slow"?
THANKS -
@jens55
No worries. You already helped me. Thank you!!!! -
The system tries to guess what it should see in the temperature rise. If it sees something that it thinks is out of the norm, it tells you about it. There are numerous parameters than can be tweaked from the 'standard' tuning and modifying them would alter the way that Duet thinks what is or isn't normal.
As long as the system doesn't throw a hard error, you can disregard the error and just keep it in the back of your mind.
A hard error is one where the system stops heating because it thinks there is something seriously wrong. -

M303: Run heater tuning
ParametersHnnn heater number
Pnnn PWM to use, 0 to 1 (you should normally use 1 i.e. full power), default 1
Snnn target temperature
ExamplesM303 H1 P0.4 S240 ; tune heater 1 using 40% PWM, target temperature 240C
I made this with my date and it was fixed. Thank
-
What you just posted is tuning for a nozzle heater.
Again, just leave out the parameter that sets PWM (P) unless you know what you are doing.
You should be running M303 H0 S60 or something in that area. -
@jens55
I used the code with my specifications.
M303 H0 P0.7 S65
Sry -
I don't understand why you insist on putting in PWM figures but if it makes you happy (and if it it doesn't give you a warning message) then so be it. Just be aware that it results in less power to your heat bed and causes a longer warmup time.

@jens55
25C - 60C
S.1 = 78sec
S.0.7 = 110 sec
Both it's ok in my mind
No warning. Thanks to. The tune was successful @Stephen6309 -
Sounds like you got it figured out.

@Phaedrux
Yes. There is nothing the forum can't help me!
Thanks to all!!!!
