Rinning???



  • What setting affect rining. ???


  • Moderator

    Usually a combination of high jerk and acceleration. But there are a few different causes of ringing artifacts. Maybe a photo? It can also be from mechanical slop, or loose belts, or belt teeth causing changes in head position.



  • ithink i loosened my belt to much you and i went thru jerk settings some time ago ive got lots to tweek i think
    thanks



  • ill run another

    What are your settings in config.g and the slicer?

    A quicker test print for ringing would be something like this

    ringtest.stl



  • Please note the rinning around prop hole by stern and by porthole on the front bow



  • K ill send shortly

    M566 X1600 Y500 Z24 E300 ; Set maximum instantaneous speed changes (mm/min)
    M203 X30000 Y1600 Z300 E1500 ; Set maximum speeds (mm/min)

    I think it may be a combination of the large mismatch in X Y speeds and jerk.

    Try

    M566 X600 Y600 Z60 E3000 ; Set maximum instantaneous speed changes (mm/min)
    M203 X12000 Y12000 Z600 E6000 ; Set maximum speeds (mm/min)

    M204 P600 T2000 ; set print and travel move accel
    


  • before i make those changes i thought id ask you this i installed a ball screw on the y axes its a 16/10 pitch...dose that impact it at al las far as the spread or figures



  • my bad for not sayin 😁


  • Moderator

    The settings I posted should be ok for ball screw axis as well. The rotational inertia of the ball screws may be contributing to the ringing. Either way, the settings I posted may help.



  • Thank you will reprint the benchy the the rinning stl 😁👍

  • The x makes me think that ive got a belt issue
    I can say its prety tight and the idler bearing is smooth because thats what i could find and thought the smooth one proably would resonate less ?????



  • So much better 🙂


  • Moderator

    It's better now?



  • Yes much thank you i think i still need to play with the hotend cooling duct. Thank you what do you think about the lines. The x axes belt ?????



  • 80% maybe 90% !!😁


  • Moderator

    I would say that it's still likely mechanical in nature. Ball screw has a lot of rotational mass, so trying to get it up to speed and slow down quickly is going to be tricky.

    Try

    M566 X600 Y400 Z60 E3000 ; Set maximum instantaneous speed changes (mm/min)
    M203 X12000 Y12000 Z600 E6000 ; Set maximum speeds (mm/min)
    M201 X600 Y400 Z300 E5000 ; Set accelerations (mm/s^2) is 500
    M204 P500 T2000 ; set print and travel move accel
    

    And if the travel moves seem harsh, try reducing M204 T2000 to T1500
