Tool Board Heater Tuning Leading To Faults

@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?

@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?

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As to the M570 I was working with out of date documentation.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

@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.

[KevinMar]

@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"

Worth a try.

At some point did you verify that each tool board is actually at the address you are using?

Frederick

[KevinMar]

@fcwilt Yes, toolboards are at the addresses assigned

[Phaedrux]

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.
