PanelDue 7i - warning message at start-up

David J

I have now got my PanelDue 7i in an enclosure and mounted on my CoreXY printer. All works very well, apart from an annoying warning message displayed shortly after start-up.

I have a vague recollection that I used to get this message on the web interface but I think I was told how to turn it off.

Is there a way to turn this off on the PanelDue?

no, you can't turn it off. It's a warning letting you know what the current heater model suspects your heather temp could reach in an uncontrolled fault. It goes away after a few seconds.

David J

I know it goes away - that's quite obvious! It's just a nuisance that used to appear on the web interface and, somehow, it got turned off.

If it's not important enough to appear on the web interface - i.e. the default, MAIN interface - why does it have to appear on the PanelDue?

Given the paneldue isn't enabled by default after RRF v3.1.0 you might be able to defer enabling it until after the firmware has issues the message about the warning?

David J

So - no real answer then?

with that attitude I guess a real answer would be get a suitably sized heater (or raise the temperature limit..)

const float noWarnTemp = (temperatureLimit - NormalAmbientTemperature) * 1.5 + 50.0; // allow 50% extra power plus enough for an extra 50C

David J

Attitude? Moi?

...actually, it's frustration. This warning message doesn't appear on the Web interface as there the system doesn't think it's important enough to report.

And it's not a particularly powerful hot-end - it's just an E3Dv6 with a the usual heater, albeit at 24v. I can't remember what the wattage is, but they only do 2 - standard (30W) and slightly higher power (40W). I believe that I have the 40W one (I'll have to check). This is a high-temp combo, rated up to 285C, so getting a warning predicting that the temp could reach 236C is rather nonsensical. But this doesn't alter the basic issue - why aren't both interfaces reporting the same warning?

It's the bed heater it is warning about (heater 0).

Oops! Sorry about that. When I started this query I knew it was the bed, but somehow my brain said "hot end" a few days later.

The bed is a 240v one controlled by an SSR - yes, it could get to a very high temp so the warning is valid, apart from the thermal fuse that's in the circuit (which the Duet doesn't know about, obviously).

But why does it show on the PanelDue, and not on the web interface? If the web interface said the same thing then I'd understand.

And can I do anything to stop it showing?

r (or raise the temperature limit..)

(236-50)/1.5 = 124

so if you can raise the limit to over 124 it should go away; your other issues seems to be more permanent sadly.

David J

Thanks - I understand what you're saying.

But surely that means going into the code? If so, it really isn't within the spirit of the Duet boards for the user to have to change code, is it? From the outset, it was always done via various config files.

Or have I got the wrong end of the stick (again)?

you clearly dont, but lest not digress.

or most likely retune the heater with (but that will heat the bed to 125C)

M303 H0 S125

if its possible to work around it, idk, its just an idea based on the code that causes the warning..

David J

Thank you - I'll experiment later today.

I can't do the second option - my thermal fuse will pop before I get to 125C.
