Hotend temp fault. Reading 425c with no connection.

I am running Duet 3 MB6HC with Toolboard Ver. 1.2, both at 3.4.1
I saw a few 2000c errors before that cleared with a power cycle.

I should point out that two different hotends report the same behavior and I can measure the resistance of the thermistor all the way to the toolboard.
-
What's the exact fault message?
What does the temp graph look like?
Please post your config.g -
@phaedrux
Sorry, should have given more info. Was a late night and a little bit frustrated.The Ver 1.2 toolboard had probably close to 200 hours of print time. The printer was working with mostly just chasing some movement issues around small, rapid movements.
I saw an error of 2000c on the hotend thermistor a couple of times that I was able to fix with a power cycle. But then the toolboard faulted out and was stuck at 423c whether a thermistor was connected or not.
I have since wired the hotend thermistor directly to the 6HC and it reads correctly. So definitely a problem with the toolboard. Is this a warrenty thing or do I have to buy a replacement board?
Thanks,
Mike -
Can you post your config.g?
It may be warranty, when and where was it purchased?

@phaedrux
Purchased June 4, 2022 from Matterhackers in the US.I have the Rapido thermistor directly connected to the Duet 3 6HC on Temp1. Though now I'm getting "Heater 1 fault: failed to read sensor: unknown sensor." which is old, since I was running a direct connection before I put the toolboard in.
I may just have syntax wrong somewhere.; config.g

@mr_phelps
Oops, forgot to say that the sensor is currently reading the correct ambient temperature. Same as the bed thermistor. -
@mr_phelps
I've switched to the second thermistor input and that is working. So I'm back to printing!
-
For the toolboard reading 425c constantly it's likely that a short (possibly from a flaky thermistor?) or ESD event has damaged the sense resistor. Is the toolboard and hotend grounded?
-
@mr_phelps said in Hotend temp fault. Reading 425c with no connection.:
I have the Rapido thermistor directly connected to the Duet 3 6HC on Temp1. Though now I'm getting "Heater 1 fault: failed to read sensor: unknown sensor." which is old, since I was running a direct connection before I put the toolboard in. I may just have syntax wrong somewhere.
Did you change the syntax? It looked ok from what you posted.
Is that thermistor working or not?
-
@phaedrux
Sorry, too many irons in the fire...
Not sure about grounding on the EVA, so probably not. I'll have to look into that.I've been running without issue on the second thermistor.
I'll try a quick look at the sense resistor the next time I have some spare cycles.
Thanks for the info!
