Attempting to extrude with no tool selected - During Print



  • This is my first Duet Wifi-based deltabot printer build, however I've built many 3D printers over the years using Marlin, Repetier and Smoothieware firmware.

    I'm really loving the new hardware and the DWC, but recently had a print fail near the end point with an "Error: Attempting to extrude with no tool selected." error message.

    Hardware is new, control board and firmware is the latest version, and I'm also running a 7i panel with most recent firmware updates. 400mm round bed, Fresh E3D V6 hotend with a .5 nozzle and a Zesty Nimble extruder.

    I'm wondering if this is a temperature issue or what else might be the problem? I've printed 10 other projects so far on this printer with the Duet Wifi and this is the first time for this error message.

    Thanks, Steve Graber

    Here is the DWC with the errors showing from last night:
    0_1555171655140_signal-2019-04-13-075841-1.jpg

    Here is the print that it failed on:
    0_1555171696794_signal-2019-04-13-075841.jpg

    I assume that the printer continued to print with no extrusion during the night because it was homed and waiting idle in the morning.

    Here is the relevant S3D initial gcode for this file: Note - There is NO Tool Select gcode anywhere else in this file except T0 at the very beginning.

  • Can you post the full gcode file?



  • It is almost 30Mb in size.

    Here is a Google-Drive link



  • Is it possible that someone accidentally clicked on something in a web interface or pressed a button on the PanelDue or accidentally bumped into the LCD panel, causing the tool to deselect?

    Your link is set to private, so I can't get it. Request sent though.





  • @bot It is not. The panel and all electronics are located at the top of the machine.

    alt text



  • What firmware versions are you running?

    I can't see anything obvious in the gcode file, and can't think of a reason why it would deselect a tool.

    Were there any other error messages in the gcode console? Perhaps a heater fault?



  • @phaedrux I didn't see anything in the code either.

    Firmware is all updated fresh last week. I'm away from the machine and can give you the M115 response later today.

    The printer has been restarted since the issue and I didn't see anything temp related but I may have missed it.



  • @phaedrux said in Attempting to extrude with no tool selected - During Print:

    M115 returns : Version 2.02(rtos) electronics duet wifi 1.02 or later. Date 2018-12-24b1



  • If it happens again, try to scan through the console page to see any other error messages, and send a M122 to get a diagnostic report.

    Also you might want to turn logging on.



  • i also am getting these same error messages during a print. really confused as what could be happening as they occur at about 6hrs in two separate prints

    Have you searched your GCode file for T commands, and checked that they all refer to tools that you have created using M563 commands in config,g?



  • @dc42 I have not, as the GCode file is 45MB and I was able to successfully complete other smaller prints with no issue. I only have one tool and it starts the print just fine. Would it be better to put the T command in Cura in the startup file section? (sorry at work and not sure of the exact term)

    The only odd thing I can think may be an issue is I used Curas "Print on my Printer" selection rather than uploading the file to Duet and then printing from the browser.



  • @dc42 just ran the same file and completed without any error, only difference was uploading it directly to duetwifi and starting print from web browser.

    There must have been an error when having Cura begin the print and the file might have corrupted on the transfer I suppose?

    It does sound like that. You may have a USB ground loop, see the wiki for details.

    USB ground loop

    well i got the same error again last night. I'm not even connected via USB is the thing, all over wifi

    1. Do you have logging enabled (M929)? If so, is there anything of interest in the log file?

    2. Did the error occur in the same place as previously?

    3. If you upload the file back to your PC from the Duet, does it compare exactly with the original?

    1. I do not have logging enabled on the config file itself, but I did export the console log file and it only thing that states was the error attempting to extrude with no tool selected, literally an hour after i first started the print.

    2. This error occurred much earlier than last time, on layer 2 of the print rather than 8 hours into my previous print.

    3. Comparing the file (checked early in the file since error occurred at layer 2) everything looks the same.

    At least positive thing to note since once the error occurs the printer does continue to print just does not extrude so at least I do not have a spaghetti monster mess of filament
