    Hi All,

    I'm having some interesting issues printing large files on the duet wifi. I started up a 185Mb print file last night and this morning found that my printer reset itself. My initial assumption was that a copper brush (for cleaning) shorted the Z-probe during tool change so I tried to confirm the diagnosis by repeatedly running the cleaning code. The code ran fine each time and the electronics were nowhere near the copper brush so I don't believe this was the issue.

    Ultimately I decided to resume the print by re-homing and manually editing the gcode as the resurrect file didn't capture the stoppage point. The print restarted fine so after a few minutes I pressed my luck with a pause-resume to see if I could replicate and witness the prior issue.

    Upon resume the printer started going crazy. extruder and x/y movements were way off from one another. The nozzle would lay down a line, freeze up mid-move intermittently and then speedup, repeat at random followed by trying to extruded so much filament that I now have globs of plastic on the print surface (see photo). This only seems to happen on large print files and its completely random on timing of freeze-up, the only thing that I could find consistent is that it happens every time after resume from pause.

    Here's the M122 diagnostics data:

        Your firmware is quite out of date and there have been many bug fixes since then. I seem to recall something similar to this maybe. I would suggest updating to at least 2.05.1. There have been a few other changes which may require some config modifications so take a look through the release notes for the intervening versions. 2.05.1 is the last version of RRF2. We're now on to RRF3.1.1 actually, but the jump to 3.x is a bit more substantial.

        https://github.com/Duet3D/RepRapFirmware/blob/dev/WHATS_NEW.md

        https://github.com/Duet3D/RepRapFirmware/releases/tag/2.05.1

        The easiest way to update is to upload the entire zip file as is to the /sys folder via DWC.

          Thank you! I updated to 3.1.1 which seemed to have resolved that specific issue.
