      So.. I haven't been able to actually test this properly, but it used to be if I enabled the magnetic filament sensor after a print started, it would stop the print for lack of movement.
      I would have to pause the print, start the filament sensor, and resume the print. Sometimes it would still pause right before the measurements came in, but that wasn't as often.
      I started an 8+ hr print with copper filament. I would hate to waste/lose this filament so enabled the Magnetic Filament monitor, but after I started the print (forgot) and it didn't stop the print. I will make sure to test this again to confirm this wasn't a one off fluke, but am now thinking that these Hiccups may have been the cause of most of the abnormal issues/behavior I have been having. Many of which I have asked for help here, on this forum.

      Thanks again!

      Fun, that 3 letter word with "u" in the middle.

        I had the same issue. Even started a thread on it i think, but it never got resolved. My suspicion was s3d , after i switched to cura i never had that problem again. After i tried s3d again for a specific print and it happened again, i just wrote it off on s3d being weird.
        I however had set x16 microstepping with interpolation everywhere, so i doubt it came from that.

        Edit: Here is the link to my thread with the same issue;
        https://forum.duet3d.com/topic/11886/duet-just-stopping-mid-print/8

        I only had it with s3d and printing thin walled things, the first were lithophanes and the second were some engine covers, all about 2-3mm thick in the xy direction

          Did you see the M122 you posted shows crazy high Hiccups too?

          Hiccups: 10265739

          Your hiccups may not have been caused by the same reason as mine, but that may be the problem. I only use S3d or Canvas when I paint a model. I don't remember if I tried using Canvas or not and saw this issue...

          I no longer have any Hiccups on my Duet2.

            @NitroFreak I can't believe I missed the hiccup count in your m122 in that thread.

            I suspect that the junky gcode generated by s3d was the cause. When doing things walled objects it inserts a ton of tiny moves (as I pointed out in that thread) to try and print a line thinner than usual. On a slow 8bit marlin board maybe it all gets glossed over by quad stepping. But the duet dutifully tries to execute every single move and gets overwhelmed?

            Curse thinwall performance isn't great either. Instead of tiny extrude moves it sometimes tries to use tiny zigzag fill which shakes the hell out of the machine.

            Slic3r and (prusaslicer by extension) is the only slicer I've seen that does a decent job of thin walls since it will allow for a variable thickness single line when appropriate rather than trying to vainly enforce a double wall.

                S3D and thinwall:

                Interestingly enough, the guys that are making STLs for printing Radio-Control Model Airplanes that fly are very oriented toward S3d. These things print single layer, with their own single layer ribs for structure (no infill). It is quite different from most of the printing that we all do... a unique capability for the printer and unique skill for the human operator.

                I do believe they lean toward S3D because of Factory Files, not for anything in the actual slicing. Many MANY parameters must be exactly right, even the orientation on the print stage, to print piece X, and it is often different for different pieces. S3D's factory files encompass all of that. Most slicers do not (or did not about four years ago when these guys got really serious about this) have a way of keeping all that in sync quite as well.

                So, no real point to this post in terms of solving anything. Just sort of an FYI on thinwall printing. And, for the record, I still more-or-less dislike S3D.

                  Like wall thickness not being less than nozzle width?

                  Re factory files, thank goodness the industry appears to have settled on .3MF finally.

                    One wall, right at, or slightly less than, nozzle. Also printed somewhat hot as compared to most printing, so 'current' extrusion melts into 'prior' layer a little bit. PLA at 230 or 240, things like that.

                    Here's my latest. Extra 550, modeled at 74" wingspan. Plane is about as big as I am. Baseball cap for scale. Haven't flown it yet.

                        Yes, it was resolved.
                        Run M122 and share your report. That would be the easiest way to tell if you are having the same problem we had.

                              How did you solve it? I also had microsteps at 256, I took them to 16 interpolated to 256, nothing changed, I also formatted the sd and did tests with other 3 sd, it never solved

                                The hiccup count could be the issue. Using x256 microstepping and having moves faster than the step rate can handle is usually the cause. Using x16 microstepping with interpolation enabled is the solution.

                                I suggest you start a new thread with your issue. Include your config.g and your M122 output as well.

                                  It appears you may have the same problem as I did with Hiccups and using 256 microstepping.
                                  @Phaedrux helped me fix it. I would follow his advice to help you too.

                                  Good luck!

                                        @BlueDust Did you solve only by changing the microsteps to 16?

                                          Did you update your Motor Steps after you changed it to x16 microstepping?

                                          Per @Phaedrux comment, you should start a new thread, and share your config.g and copy of M122. ( I know you already shared it here, but makes more sense to keep it all together to make it easier to troubleshoot on a new thread).

                                          And yes, changing to x16 microstepping fixed the issue for me. You should make sure to share a new M122 on the new thread after you updating your microstepping to see if you still have a high hiccup count. It was the high hiccup count that caused the issue. It was just 256 microstepping that caused the high hiccup count.
                                          Also, In my case I was printing for over a year before this issue showed itself. I am not sure if it was updated build, or some other changes that made it finally cause problems during a print.

                                          Fun, that 3 letter word with "u" in the middle.

                                            @BlueDust This M122 that I posted is already with microsteps, and updated steps to 16 interpolation 256, I will do a new discussion. Thank you
