Web printing doesn't work for me



  • Hey guys, I just recently got my duet wifi board and got my printer configured with it, but I am having a problem with printing through the web interface. I use cura as my slicer and save the gcode files and upload them to print. When I tell the web interface to print the files, it starts to heat up the hotend to the desired temperature but stops after it reaches that temperature and says the print is finished.

    I am using firmware 1.18.1, wifi server 1.03(ch fork), and web interface 1.15a. I feel like i might be using the wrong version of one of these.

    I would really appreciate any help.
    Thanks.

    Check the gcode console page of the web interface for error messages. If you don't see any, please post the first 50 or so lines of the gcode file you are trying to print.



  • Ok the console didn't show any errors, so here are the 1st 50 lines

  • I'm getting the same type of behavior. Bed and hotend heat up, machine homes X,Y,Z, then print goes to 100% finished and machine starts to cool down. I'm running the same firmware versions as Ian Tech. Config generated by the online tool as well.

    Gcode console only reports the file was selected for printing:
    [c]12:14:19 AMM32 2020_nt.gcode
    File 2020_nt.gcode selected for printing[/c]

    I'm generating my gcode with simplify3d, first 50 or so lines:

    I've tried with G29 S1 to load height map, and just as G28 without but no dice either way.

    Hopefully that helps diagnose this as well.



  • I'm away from home and on my phone right now but seem to remember something similar in another thread and the fix was to change the "flavour" from reprap to Marlin.



  • I just tried a new RRF config in case something was wrong, and it defaults to Marlin, deckingman. I tried toggling it to something else then back to Marlin, but it's still not working. I downgraded to 1.17E and I'm still getting the same results. All the previous gcode on my machine that worked now exhibits the "100% finished after homing" behavior. Maybe this was a result of the web interface upgrade? I'm going to see if that's downgrade-able next.. machine worked fine on 1.17E and the previous versions of web interface.



  • Just a thought. Have you got your config.g set to use absolute extrusion to match what you are using in the slicer ? If it's set to use relative in config .g but absolute in the slicer, that might screw it.
    The comment about firmware flavour was for the guy using Cura as there is a comment in his start gcode saying RepRap as the flavour.


  • administrators

    @Ian Tech, your gcode looks OK except that I recommend you include M82 in your slicer start gcode to tell it you are using absolute extrusion (Cura doesn't support relative).

    @forgets, your gcode looks OK too, but as you are using S3D I recommend you switch it to use relative extrusion.

    Both of you, what M563 command are you using to define tool 0?



  • @dc42 I added M82 to the start gcode and M563 P0 D4 H1 but there was no difference.

    @deckingman The reprap option says marlin and sprinter in parenthesis in cura



  • @Ian Tech try hand editing your homeall.g file.. I took out all the extraneous spaces and notations and it prints again. I think it's possible the RRF configurator is adding some characters in that are causing it to stall / pause. I hope the fix works for you Ian Tech.

    @dc42 I'll post if I find any differences so hopefully it can get sorted out. Maybe there's a character limit being exceeded with the homeall.g file that's being generated by RRF configurator? I just redid my settings for the file by hand typing them out and it works.. so… it's fixed.. but it seems like there's a bug there somewhere. Let me know what you need me to post to help you replicate so it can be squashed for future versions.


  • administrators

    If you can send me a homeall.g file that replicates the problem, that would be helpful.



  • Ok Removing many comments in homeall.g fixed the problem… Thank you guys for the help
    @dc42 I don't have it but more than 1/2 of the whole file was comments.
