Strange problem you are having.

You posted a screen shot showing heaters Ex0, Ex1 and Ex3 faulted.

Were all three heating at the time?

M308 S1 P"20.temp0" Y"thermistor" T100000 B4725 C7.06e-8 A"Ex0"

On T0 you use a thermistor but not with the other tools?
What is your tuning command.

[KevinMar]

@fcwilt Yes, all 3 faulted (nearly) simultaneously, when heating is initiated simultaneously

[KevinMar]

@diy-o-sphere Changed to thermistor (actually changed hardware) just to try troubleshooting

@kevinmar
CAN addresses set correctly?

@kevinmar did you see my comment about retuning with a silicone sock in place, and my suggestion to reduce the M307 R parameter?

[KevinMar]

@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 even to 1.0 and it didn't help

[KevinMar]

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

Did the R value change much when you added the sock, or was it just the C values that changed?

If you execute a M570 command from the DWC Console what value does it report?

Frederick

[KevinMar]

@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"

[dc42]

@kevinmar confirm you are running firmware 3.3 on both main board and tool board?

[KevinMar]

@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

[KevinMar]

@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?

[KevinMar]

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As to the M570 I was working with out of date documentation.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.
