M207 response too long see console



  • Hi All I am trying to fine tune a Diamond 3 in 1 out hotend on my duet maestro based printer. Tool setup and much of my study has been helped greatly by blogs and posts from user Deckingman.

    I am now trying to improve or tune retraction / oozing but hitting a few issues I have

    M207 S7.5 R0.0 F2400 Z0.2
    

    But Z is NOT hopping as expected
    Despite changing the S value in the above M207 my retractions don't appear to change.

    If I issue M207 in the dwc console I get

    M207
    Tool 0 retract/reprime: length 2.00/2.00mm, speed 16.7/16.7mm/sec, Z hop 0.00mm
    Tool 1 retract/reprime: length 2.00/2.00mm, speed 16.7/16.7mm/sec, Z hop 0.00mm
    Tool 2 retract/reprime: length 2.00/2.00mm, speed 16.7/16.7mm/sec, Z hop 0.00mm
    Tool 3 retract/r
    

    Then a warning M207 response too long see console.

    Any help appreciated.

    So if you switch to the Console tab of DWC, what is the message?



  • Yes this is from the console.

  • Out of interest I get the same Response too long see console notification warning if I send M122. Not sure if that helps at all.

    What is your DWC and firmware version?



  • @Phaedrux unless I’m mistaken the above photo shows my console screen where you can see the incomplete result of my M207.
    What I can’t screen cap is the warning



  • Sorry that should read I cannot screen cap the message because it times out

    @lyndon any response longer than three lines generates the warning to see the console, as the message can’t be shown in a pop up. Not sure why you’re getting a truncated response though.

  • @lyndon Welcome to the insane world of mixing hot ends. I've never used Z hop so may not be much help. But post your entire config.g, I might be able to spot something. Also, let us know what version of firmware you are using.
    As others have said, the "Response too long" message isn't an error. It just means that the response is too long to fit into a pop-up window so you have to look at the console to read the full response.

    Yes it look like a fun world.

    Ref the response too long, I agree BUT that is my console screen. Not the M207 response in the pop up ??

  • Here is a photo of my console screen with warning. Please excuse the quality

  • @lyndon Those look like default values to me because not only is the Z hop at zero, but also the retract length is being reported as 2.00 whereas according to your config.g, it should be 7.5 mm.

    Possible reasons are that there might be another M207 somewhere which is overriding the first one. Try sending M98 P"config.g", to re-load then send M207 again.
    Alternatively, you might need to update the firmware. The latest version for my gen 3 boards is 3.1.1 but I' not sure if that applies to the Maestro as well.



  • Quick follow up after some more play time, I have found the M207 retraction code line must come after tool definitions in config.g. Now I have accurate values in the console response to M207. However still truncated and I do still get the pop up message response too long.

    M207 S2.5 R0.0 Z0.2 F2400
    

    That said I seem to have a printer that's now listening to my retraction settings.

    But before moving the M207 line in config.g, the machine was retracting I guess by the values shown in my previous M207 response. Perhaps this is a default setting.

    So when I was dynamically changing retraction during a print by sending console M207 bla bla bla, I may not have been changing anything hence no improvements to print quality.

    More fun to be had



  • @lyndon You will always get that pop up message. It isn't an error or warning. It is merely to draw your attention to the fact that the response was too long to fit in a pop-up window and that you should look at the console to see the full response.

    Yes, as stated above - those values look like default values.

    BTW, I just tried sending M207 on my machine and I too get the same truncated response. Although, because M207 gets applied to all tools, one could argue that the response is unnecessarily long, as it only needs to report one set of values. This seems to be a minor issue with DWC which ought to be brought to the attention of ChrisHam. But I wouldn't worry about it - it won't affect anything.



  • @deckingman said in M207 response too long see console:

    M98 P"config.g"

    Console response to the above is again truncated and is:-

    M98 P"config.g"
    HTTP is enabled on port 80
    FTP is disabled
    TELNET is enabled on port 23
    Warning: Heater 0 appears to be over-powered. If left on at full power, its temperature is predicted to reach 365C
    The M568 command is no longer needed
    The M568 command is no longer needed
    The M568 command is no longer needed
    The M568 command is no longer needed
    

    Followed by the same pop up. Response too long.

    I agree and understand and the message doesn't bother me as much as the truncated responses, I'm getting it on several M codes such as M122

    PS I have also updated dwc and firmware to ver 3.1.1
    Cheers



  • @lyndon That response is fine. It isn't truncated. That is the normal response from running the macro "config.g".

    BTW, as you can see, you ought to remove all those M568 commands from your config.g. Since firmware 1.19, setting the mixing ration with M567 automatically turns on mixing.

    I have started a new thread in the DWC section to bring the M207 response to Chris Ham's attention.



  • @deckingman oops my bad it looked truncated.

    I have now removed the M568 from config as suggested.

    Cheers all


  • administrators

    I've made a note to fix the truncation of M207 output when there are >= 4 tools in firmware 3.2.
