Duet Wifi Unable to get past warm-up



  • HI All,
    I apologise in advance, this will be a rather lengthy post to give all of the information i believe is relevant. I'm going to break it into smaller sections so you're welcome to skip over whatever is not relevant to the issue.

    General / Issue Background
    My Duet Wifi appears to be functioning as intended for the most part - i can move all axes, i can heat up heat bed and the stepping seems to be correct on all of them (or within tolerance at least). When i start a print, the system heats up the heat bed during the warmup phase, then heats up the hotend to the desired temperature. Both ht the correct temperature, as the first layer begins and it halts, says 100% complete Layer 1 of 198, Filament Usage 0.0mm of 1455.0mm. The Extruder has not moved at this time.

    See here: http://imgur.com/a/9mq8H for an example of what occurs at the point of failure. A couple of things to note, the alert triangle at the top dissappears almost immediately - to the point that i have never seen it before and was just obscenely lucky to get it in that particular picture. Furthermore, the gcode console has no alerts or warnings - http://imgur.com/a/n4wXA. This has made this a difficult issue to track down as there are effectively no warnings as to why this has occurred.

    Unit Background
    Purchased approximately 12 days ago - have never managed to get a print out of it. Have managed to extrude plastic and have it move around however, never cnc/automatically. Have had other issues along the way, but nothing too drastic.

    Running off an ATX power supply (12V).

  • That is an incomplete Gcode file, it shows that there should be 198 layers if you read it…. but then the only gcode that follows is for the skirt.... it is missing the gcode that prints your part



  • I cut the other lines from the Gcode file - its my understanding it goes sequentially and never gets to the skirt anyway, so the issue would be up top. I can post the full file if desired - its just movements however.


  • administrators

    One problem I can see is that you are using Cura, which always outputs absolute extruder moves, but you have M83 in your config.g file. I suggest you add M82 to the start gcode in Cura.

    But this doesn't explain why the print completes at layer 1. We might need to see more of the gcode file.



  • Full Gcode https://justpaste.it/19hkt

    What would be the preferred slicer for this board? I'm not exactly sold on cura, it just appeared to be everywhere at the moment so i thought i'd give it a shot. I used to use Skeinforge, but i was looking for something a bit more straightforward…

    Cheers for the advice thus far!

    Please can you put that gcode on a file sharing site and then edit that last post to link to it instead of including all of it in that post. I am using a tablet and it would take me forever to scroll to the bottom of that post.

    Does the G28 homing command complete before DWC says the print is complete? I am wondering whether something in your homeall.g file could be to blame.

    I have updated the original post with a link to a paste site. The G28 command doesn't run or at least doesn't run fully. I'm not sure what order G28 actually runs in but i have heard a click (like the endstop un-triggering perhaps, or a relay potentially) prior to the print saying 'completed'. It all seems a little odd to me.

    G28 homes the printer. If you send G28 from the console, does the printer home correctly?



  • +@dc42:

    G28 homes the printer. If you send G28 from the console, does the printer home correctly?

    Alrighty, seems things are a little odd when i run that command (whee, getting somewhere!).

    To explain the behaviour; its a corexy printer, running g28 when;

    • the x/y endstops are triggered, only the z axis moves, homes normally and then stops.

    • The X endstop is triggered alone, y moves back into position & rattles in place (trying to drive) once endstop triggered

    • The Y endstop is triggered alone, x moves into position & rattles in place (trying to drive) once endstop triggered

    It appears that those two endstops aren't stopping the x/y axis when g28 is run. Using the +10/-10 triggers however, the endstops are adhered to.


  • administrators

    I can see 3 problem with that homeall.g file:

    • The line "Move away from the endstops" begins with a colon instead of a semicolon. Fix that and I think your print will work.
    • The G1 command on the line following "Course home X" should have S1 at the end
    • Same for the line after "Course home Y". Fix those 2 and homing should work.

    We will fix configtool to generate these lines correctly in future.



  • Looks to me like you are missing few "S1s" in your homing file.

    Going through your homeall file it's fine up to course home X and Y. The next command you have is
    ; Course home X
    G1 X-205

    That should be G1 S1 X-205 (the S1 tell it to look for an end stop to be triggered)

    The following line is the same. That is to say G1 Y-195 should be G1 S1 Y-195.

    The rest looks OK at a glance.

    Edit. Was typing while DC was typing (and I missed the colon that David spotted).



  • Thank you dc42! (& deckingman!)

    I'm now able to extrude plastic. That was a little tougher than i anticipated but have a position to launch myself from.

    Thank you very much!


  • administrators

    Glad to help, and I'm sorry that configtool introduced those errors.
