Tool Board Heater Tuning Leading To Faults

KevinMar

@fcwilt Ambient is 26-30C
I am not getting a fault readout in the console

KevinMar

@diy-o-sphere No, old parameters are overwritten when a new set is generated and saved using M500

Wow. I gather it is hot were you live and you have no air conditioning?

I am not getting a fault readout in the console

You posted this where you said there was a fault.

The tuning runs fine, but when I paste the parameters into config.g, the resulting heater activation inevitably results in a fault before the tool reaches 120C, usually around 70-100C

KevinMar

I think it's faulting way too liberally. My heater and PT1000 are working, it's not like I'm experiencing thermal runaway.
Is there a way to change the sensitivity of the faults?

What fault are you getting?

KevinMar

@fcwilt Well, true ambient is about 24C, but the PT1000's always read about 27C as ambient.

The heater faults, but there is no readout in the console.

In what way does the heater fault?

KevinMar

@fcwilt I wish I knew!

What is happening that is evidence of a fault?

Please post the config.g

KevinMar

@diy-o-sphere config (1).g

@fcwilt

OK that helps.

All all three heaters actually active at the same time?

Do they all fault at the same time?

Can you take a screen shot of the temp graph showing the heaters as they heat up and then fault?

Your sensor settings a looking wrong...

Here is an example of mine
M308 S1 P"temp1" Y"pt1000" R2200 ; configure sensor 1 as PT1000 on pin temp1

@diy-o-sphere Huh, yeah that ain't right

dc42

@kevinmar if you are running without a silicone sock on the heater block, please add a silicone sock and re-tune. Your M307 parameters suggest that the fan substantially cools the hot end, which typically means that the fan is blowing on the heater block.

Also please confirm that the part cooling fan is off when you command heating and the heater 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.

From the docs:

Additional parameters for PT1000 sensors

Rnnn Series resistor value. Leave blank to use the default for your board.
Lnnn ADC low offset correction, default 0 (ignored if the hardware supports automatic ADC gain and offset calibration)
Hnnn ADC high offset correction, default 0 (ignored if the hardware supports automatic ADC gain and offset calibration)
