abnormal noise when changing direction

[dc42]

@nok please switch to spreadCycle again, run M569 to confirm that the drivers are in spreadCycle mode, and record the sound again, so that we can eliminate stealthChop from the suspects. Also, when the arc is being printed, watch the "Requested speed" and "Top speed" figured in DWC and see whether they are the same.

If you post the GCode file or make it available on Dropbox or Google Drive etc. then I can try it on my delta.

@dc42
i think you want eliminate me from the list of suspects or…
maybe you are robots and can't read my above posts correctly?
let's find out…

i’ve been trying to find the error myself for weeks now. i’ve read mountains of forum posts and i tried (like i said in my previous posts), who knows how many different settings for jerk, speed, acceleration, currents, pressure advance, retraction… all in spreadcycle as well as in stealthchop mode, with 1.8° and 0.9° stepper + different cables. with and without slicer, extruder and hightmap involved… the whole spectrum up and down. but this problem is ALLWAYS present.
through my years of experience with 3d printers, i would say that something is fundamentally wrong and not setting related. with the old chinaboard (also with 2209), this printer was super quiet and work totaly fine before i switch to a duet board.

i did the moves in the audio recording without a slicer generated gcode, i use only dry G1 and G3 commands send via dwc. so, don't waste your time with the print of my gcode. and btw time; thank you very very much for yours, both of you! i’m very thankful for your help!

i made a new testprind where you can hopefully better see/hear whats going on in curve sections. in the first part of the video, hotend and part fans are turned of, so what you hear are only the motors. requested speed and top speed are always the same in dwc.

spreadcycle is selected in config and active

@nok I'm sorry, somehow I missed that your sound recording was taken in spreadCycle mode. I'll review your latest video tomorrow. As it happens, today I finished converting my delta to Duet 3 Mini, so I will be able to run your code on it.

@dc42
any news regarding the problem?
to rule out the firmware as well, i updated to 3.4.0RC2, but nothing changed.

[dc42]

@nok sorry no news yet, I've been busy with other things today.

@dc42
any news after 10 days?

[dc42]

@nok I've listened to your video again I don't think those noises are anything unusual. What I think is happening is that when drawing the large circles, the step frequencies of the motors vary through a wider frequency range than they do when printing straight lines, and at one point the frequency is exciting a resonance in your mechanics. The high microstepping capability of Trinamic drivers makes them quieter in normal operation; which means that when you do encounter a resonance, it stands out more.

It may be the stepper motor mid-band resonance that is being excited. See https://phidgets.wordpress.com/2014/07/28/how-to-avoid-resonance-issues-in-stepper-motors/ for more details.

The frequency of mid-band resonance varies approximately with the square root of motor current; so you may find that the pitch of the vibration varies with motor current.

@dc42
please check out my new videos. this time (as in the audio file) the moves are in stealthchop mode.
i entered the commands via DWC. i think that's more meaningful (especially the slow movements) than hearing it while printing.

@nok on the last move of the slow move video, I can here some mechanical creaking noises. I think they are probably caused by a sticking ball joint, or possibly a sticking linear rail.

[RogerPodacter]

i searched and found this topic. today i ran a certain gcode file which contained round circles and my printer, really the extruder, made extremely loud grinding noises. the sounds were quite severe. i suspect it might be the same thing as this thread. all i can describe is loud grinding.

this is on the first layer, when making a perfect circle approximately 40 mm diameter. as soon as the circle is done, the extruder goes back to dead silence making other shapes like squares, lines, etc.

is there a way i can troubleshoot this?

but if i run something like the voron cube which has the round center, the machine flies quickly thru that circle smoothly and silent.

You may want to raise your Z and E jerk values. 6mm/min is very slow and could be limiting your XY movement in unexpected ways especially if you have mesh compensation active. Same can be said for a too low E jerk value. A circle is made up of many small segments, and with a low jerk value the extruder may be trying to halt at each segment connection. Try increasing your E jerk to 1000, 2000, or even 3000. And increase your Z jerk to at least 60.
