@jay_s_uk Hello, TKS for the reply. I was sitting near the machine when it happened again, this time I seen the error message : Over temp shutdown reported by drivers 3-4

console.txt

Machine just stops with no displayed errors, running Duet2 board, no heater faults, nothing. This has happened a number of times recently running different jobs and in no specific spot each time, both extruders and bed heater just turns off.

I don't remember the gcode command to list errors or history, can someone help me?

I checked with the manufacturer for their latest firmware, 3.1 is their latest release. Two of the three resellers for this equipment no longer sell/support these machines, getting a response from the manufacturer's support team is often very difficult.
These 400 machines are available with four options for extruder systems, three of which are proprietary and one is an E3d Volcano, the standard extruders for these 400s are no longer available or supported, which forced us to seek an alternative system. On one machine we're running Volcanos ( running well with no issues) on the other machine we're running Super Volcanos ( experiencing issues.)
With the companies latest firmware release, they did include the option of Super Volcanos as part of the machine set-up, however, they don't sell the extruders with their machines. I purchased The Super extruders, installed them and they wouldn't work, what I discovered was that the firmware is set up to run PT1000 thermistors with the Super, however, the purchased extruders came with standard E3D thermistors. The manufacturer suggested that because we don't run high temps, just run them using the regular Volcano set-up. Could this be the issue?
As far as cooling, the control board is being cooled by a fan in an enclosed panel. I've attached the M906-M913 reports as well as the Gcode for both extruders sets.

Again, thank you so much for your help!

I didn't create the macros, this is a purchased machine and what you see is how it was set from the factory.

@phaedrux Thank you for taking the time to reply to this issue!
The control board (Duet 2) is in a well ventilated (cooling fans) enclosure in a temp controlled room.
This has happened a number of times, some soon after starting the machine, most often 2-3 days into a print, this time it was 3 days into a 8 day print. It shut down sometime during the night and when I ran the M122, seen the error message, every thing had cooled off.

Attached is the config file "Config.g

Machine shutting down error :over temp shutdown reported by drivers 3 &4 . What could be causing this issue?

Thanks for the reply, I'm running another job now without it connected to Web Control. If it doesn't stop again, maybe I can isolate the issue better.

Beginning to have issues with print jobs just stopping and disconnecting from Web Control. It stops in different places and with different jobs, turns off all the heaters and stops where it is at during the print. Nothing is being touched on the machine nor on the laptop, this is Duet 2 controller on a 3D Platforms Series 400. The power doesn't turn off, it just stops, I don't see any error messages either, has anyone experienced this type of issue before?
