RRF3 heater configuration fail
-
@ethelred You need to run the heater PID tuning step.
Sorry that this is a link to the old documentation.
I can't ever find anything in the new documentation.

Heater tuning in the new wiki:
In the Commissioning guide - https://docs.duet3d.com/en/How_to_guides/Commissioning#h-6-tune-heaters
In the User Manual (under connecting hardware > Heaters > Tuning the heater temperature control) - https://docs.duet3d.com/User_manual/Connecting_hardware/Heaters_tuningIan
-
@ethelred If you mean that your temperature is showing as -273C, I think that's due to your thermistor configuration. If you have Semitec 104-GT2 thermistors (eg E3D thermistor), your C parameter is way out. It should be:
M308 S0 P"bedtemp" Y"thermistor" T100000 B4725 C7.06e-8 A"BED"Ian

@droftarts
You da man. The C factor was off by a mere 8 powers of 10. I had stared at and compared the old>new configs ad nauseum and didn't see the missing exponentials. Thanks much. -
Sorry I jumped in without checking closer.
Sometimes I'm in a hurry and miss the obvious stuff.
I do think you'll need to do the PID tuning again though, so the links provided are still useful.
Good luck man.

@droftarts
Still a problem in heater and sensor mapping that I've been unable to cure. As below note that both heaters are driven by the EXT heater - ie - if I enter a temp into either bed or tool "active" the extruder temp only responds. No bed heating occurs - only the nozzle heater.

@alankilian
Would you mind posting the heater section of your config? Maybe a character by character comparison might yield a positive result.

Sure, here's my full config.g:
(I have a Rostock Max V3.2 with an SE300 hot-end. I don't know if that's what you have.)
Is it really 137 degrees F where you are?

Is there a particular reason you've stopped at 3.1.1 firmware? I would suggest going all the way to at least 3.3. if not 3.4
The display of temp thing may be that you've got the wrong sensor/heater mapped to the tool. Please post your full config.g file.
It would also help to see the results of M122 and M98 P"config.g"

@alankilian
Thanks to all heaters finally sorted. Mainly typos with a spoonful of stupidity.
Installed 3.4.1 and did a character by character proof.
No, not 137F ( a pleasant 82F today). The displayed 57c was, I guess, a clever artifact of my config.g construct.
