@fcwilt I do use PT1000 and 100's as well and do prefer them and don't have any need for the additional Params as yet but we will see Hopefully Kevin gets it all sorted

Do those devices require additional hardware to connect to a Duet board?

Frederick

pt1000 no but the pt100 does need the daughter board

Not required for PT1000 on Duet3 and Maestro

nor on a wifi/ethernet duet 2 board either just not quite as accurate due to the 4k7 sense resistor rather than the 2k2 one

New parameters: M307 H2 R2.050 C309.100:130.600 D6.20 S1.00 V24.3 B0

Another fault:

(I had been using the fan to cool the hotend down, so ignore values before 11:00)

Did you check your config-override.g file to see if it included M307 commands?

Frederick

KevinMar

@fcwilt it included M307 commands that were generated from the autotuning and saved using M500

So we can ignore the ones in your config.g file?

Frederick

KevinMar

@fcwilt They're identical

So you copied the lines from the config-override.g file and put them into your config.g file?

I assume you re-booted.

KevinMar

@fcwilt Affirmative

@fcwilt Affirmative

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

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?
