        @Notepad thanks. For these types of error it's the info in the error message that reported Code 7 that's important, but unfortunately you haven't provided that.

        However, I believe I have identified and fixed the cause of Code 7 errors. We expect to release 3.6.0-rc.1 very soon.

            @Notepad yes, code 7 halts were very rare. The cause I found (supported by debug evidence from two users) only occurred when a particular combination of events occurred. One of those events was the 32-bit step clock counter rolling over to zero within the duration of a move segment in a particular context. That rollover happens once every approx. 95 minutes on Duet 3.

                @Notepad thanks, that has the very large 'd' value that is characteristic of the Code 7 error that I fixed in rc1. I presume you were running beta 4 or earlier when that message was generated.
