@diy-o-sphere lol yeah, boards working fine otherwise

@dc42 said in Tool Board Heater Tuning Leading To Faults:
If after re-tuning with the silicone sock on (if necessary) the heaters still fault, you can try reducing the M307 R parameter. Try a 30% reduction.
I added the sock, retuned, and it still faulted.
I reduced R from 2 to 1.5 and it didn't help
Did the R value change much when you added the sock, or was it just the C values that changed?
-
@kevinmar said in Tool Board Heater Tuning Leading To Faults:
@fcwilt Yes, all 3 faulted (nearly) simultaneously, when heating is initiated simultaneously
If you execute a M570 command from the DWC Console what value does it report?

@dc42 C values changed when tuning with the sock.
R values were a manual change
-
@fcwilt "Print will be terminated if a heater fault is not reset within 10 minutes"
-
@kevinmar confirm you are running firmware 3.3 on both main board and tool board?
-
@dc42 yes, 100%. All running 3.3 non beta or anything

As a test have you commented out the settings for all but one tool heater to see if that makes a difference?
Frederick
-
@fcwilt huh? Just comment out all of the heaters? I have not tried that.
Should I add "M570 H1 P10 T15 S0" to my config?
-
The thing that keeps confusing me is that this is a very standard-issue setup. Running all standard E3D + Duet hardware, and running a stable release of the firmware.

I was wondering if the same problem would occur you if you only had one extruder heater configured.
As to the M570 I was working with out of date documentation.
It turns out with current firmware it appears you have to have a H parameter to set/report on a given heater.

It most certainly is confusing but I would not be surprised if we are overlooking something that should be obvious.

@fcwilt Me too, but I've been digging

When I'm faced with something like this I resort to a process of elimination, thus my suggestion to configure just one heater to see if it changes anything.
-
@fcwilt I've commented out all heaters except H2, autotuning now.
"M308 S2 P"21.temp0" Y"pt1000" A"Ex1"
M950 H2 C"21.out0" T2 ; Heater for extruder out tool 1
M307 H2 R2.050 C309.100:130.600 D6.20 S1.00 V24.3 B0
M570 H2 P10 T25 S0.1" -

M570 H2 P10 T25 S0.1"Worth a try.
At some point did you verify that each tool board is actually at the address you are using?
Frederick
-
@fcwilt Yes, toolboards are at the addresses assigned
-
Can you send M98 P"config.g" to check for any syntax errors?
I'd also suggest generating a basic config using the online tool and trying with that.
Perhaps a photo of the hotend itself my give us some clues.

I've got a test setup on my workbench but it only has one tool board connected and it works fine.
Perhaps there is some as yet undiscovered firmware problem that only manifests with multiple tool boards.
