hotend and bed stops heating

Hello,

Since 2 days , hotend and bed stops heating randomly while heater1 and bed go "off" and printing stops immediately.
Duet 0.6 with Release 1.17e of DC42 reprap firmware.
M122 don't report errors.
Duet isn't reset but only hotend and bed goes Off
I checked everything but I'm without of ideas.

What do you think about this problem ?

Thank you

Sounds to me that you had a temperature fault. Check the heater status in the DWC Machine Control page, also look for error messages on the Console page.

Did you auto tune the heaters?

When I test to disconnect the hotend temperature sensor while printing, I have an error in DWC control page "Error: Temperature reading fault on heater 1: sensor open circuit"
However, in my case, I don't have errors message in the console and DWC control page indicate "Off" for Hotend and bed.

I haven't auto tune the heaters. How can I do ?

Nothing seems to you wrong in my config.g file ?

You don't have a M501 command at the end to run config-override.g. You will need that if you run auto tuning and then run M500 to save the results in that file.

After your last answer, I have tuned hot end heating with M303 H1. results have been stored with M500 in config-override.g file.
I have deleted M305 line in config.g
After first printing test and about 33mn, printing stops in the same time that Heater 1 and Bed go "Off" on DWC machine control page.
M122 don't reports error, no message in the console and no reset on Duet

Is there a security if one stepper motor is too hot ? (too much mA defined for exemple)

Next time, please look at the "Last reset time" in the M122 report , to see whether it corresponds with the last time you turned on (or otherwise reset) the printer, or whether it corresponds with the time that the print stopped. Also the "Last reset reason".
