Tool Board Heater Tuning Leading To Faults

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.(UTC+1)
-
@fcwilt Yes, all 3 faulted (nearly) simultaneously, when heating is initiated simultaneously
-
@diy-o-sphere Changed to thermistor (actually changed hardware) just to try troubleshooting
-
@kevinmar
CAN addresses set correctly?(UTC+1)

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

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As to the M570 I was working with out of date documentation.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