Thanks droftarts and dc42 for your answers.
@droftarts said in Duet2 Wifi - Heater fault in one at a time prints:
@Javi-vH Is it the bed or hot end that generates the fault? Do the temperatures look stable on the graph in DWC? I had a quick look at the gcode, but can't see anything obvious, searching for temperature changes. Also, what firmware version? Send M115 and post response.
Can you check the gcode on the SD card is the same as the one Cura generated? Perhaps it is corrupted.

The fault is generated by the hotend (it gets purple in PanelDue). The temperatures look stable in the DWC, here is an example of the current print:
The gcode readed from DWC looks the same as the one generated by cura.
I will check it and post the response as soon as the current print finishes. The firmware version is 2.05.1 (2020-02-09b1) and the hardware version is 1.04, I got the board one week ago.

There should have been another error message before the one you listed, indicating what sort of heater fault occurred.
See https://duet3d.dozuki.com/Wiki/Spurious_heater_faults_and_how_to_avoid_them.
You're right, I missed a line:
Error: Heating fault on heater 1
Resume state saved
The thing is that this error happens after the first print finishes (perfectly) and this error does not happen during "normal" prints. Anyways, I am close to the limit temperature and according to the article you sent it could be the problem, so I will modify the value and check again.
Firmware configured temperature limits
The M143 gcode limits temp to at preconfigured limit. A Heater Fault error if temp is above this limit. Set it in config,g
The defaults depend on the firmware version:
300°C prior to RepRapFirmware version 1.13, and 262°C from 1.13. At RepRapFirmware 1.17 the default maximum temperatures were 262C for extruders and 125C for the bed. In more recent versions the default maximum heater temperature is 290C, to allow the hot end to be tightened at 285C as per the E3D recommendation.
