Unfortunately not. If I had access to the printer I could provide more info but I don't and my friend isn't really capable of debugging.
We suspected that the sd card might be acting up (it isn't the one duet sends).
The firmware is 2.0.0 if I remember correctly.
The gcode is generated in PrusaSlicer and the problem occurs mid print. So gcode should be fine. I printed a million calibration cubes when I was there just fine.
We will try this and see if it helps: https://duet3d.dozuki.com/Wiki/Network_disconnections_after_uploading_large_files
