Tool Board Heater Tuning Leading To Faults
-
@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As to the M570 I was working with out of date documentation.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?

-
@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.

Here's my new, super simple configM550 P"ToolChanger" ; Set machine name M111 S0 ; Debug off M929 P"eventlog.txt" S1 ; Start logging to file eventlog.txt M555 P1 ; Set RepRap output G4 S1 ; Wait for expansion boards to start M308 S2 P"21.temp0" Y"pt1000" A"Ex1" M950 H2 C"21.out0" T2 ; Heater for extruder out tool 1 M307 H2 R2.063 C316.300:132.500 D6.10 S1.00 V24.3 B0 M143 H2 S300 M950 F11 C"21.out2" M106 P11 S255 H2 T70 M950 F1 C"21.out1" M563 P1 S"Tool1" H2 F1 G10 P1 S220 R205 M570 H2 P10 T25 S0.1 G29 S2 T-1 M501 ; Load config-override.g -
boom, fault at 70c
It's most commonly faulting at 70c, which is when my hotend cooling fan is enabled

@kevinmar said in Tool Board Heater Tuning Leading To Faults:
M501 ; Load config-override.gDoes that M307 line match what gets loaded by config-override?
-
@phaedrux always
-
And if you execute M98 P"config.g" does it show any errors?
If you delete config-override.g completely and remove the M307 line entirely from config.g, reboot the board and tune from scratch and save with M500 does it produce the same M307 line?

Drat.
Does the fault occur when the temp is rising? peaked? dropping?
Did you leave all the tool boards connected?
-
@fcwilt All boards connected, happens ALWAYS when heating up. Never reaches peak or anything

But it seems to be happening when the cooling fan kicks in?
Have you changed the temp of the cooling fan to see if the fault tracks that temp?
How about adding a M570 for that heater and increase the default P parameter value (5) to something like 30.
