Voron V.02 Noise

dimky · Jun 14, 2023

Hi gents.

Just built my .02 kit from Siboor but have a problem with strange knocking noise when print head is changing direction. Printing quality is good with no any issues, however this noise I don't really like. Could you please advise what could be wrong here?

transonic_gecko · Jun 19, 2023

Wow, that is noisy. Out of curiosity, what are your microstep settings in your printer.cfg file?

dimky · Jun 19, 2023

Hi Gecko.

Microstepping is set to 32 for X, Y and Z.

transonic_gecko · Jun 20, 2023

I built the LDO kit, not Siboor, so I'm not 100% sure I'll be able to help since I haven't encountered the noise. However, I'm willing to at least try. Could you post your entire printer.cfg file?

dimky · Jun 20, 2023

Hi Gecko.

Understood, thanks anyway.

Sure, here is printer.cfg attached:

That sounds like you have interpolate off on your stepper settings in your printer.cfg. But by the sounds of it, it is off for some of the drives and on for others. I turned it off on my steppers and I hear the same noise, I don't think it hurts anything just noise but more accurate.

FWIW interpolate is OFF in my config file, and I don't hear any such noise.

I have StealthChop disabled, too, of course.

dimky · Jun 20, 2023

Hi guys.

Enabled interpolation in printer.cfg and still same issue...

Well, Ingold, that sounds hurts my brain.

I replayed the video, and it hurts my brain too. I did notice your stealthchop is at 200. Did you set that to 0? I turned stealthchop on once, and the noise made my ears bleed.

Stealthchop should actually make the motors MUCH quieter. If you turned the option "ON" and it made more noise, then that's really weird.

dimky,

The first thing that pops out at me is that your run_current is super high on the x and y stepper motors at 1.1A. You're really getting a lot of torque at that current and I wonder if that's not causing the noise. I use 0.5A for the run_current in my x and y steppers, and 0.37A in my z stepper (these were defaults from the LDO configuration file).

dimky · Jun 21, 2023

Hi guys.

Thanks, but nothing helps. The only way to get rid of that knocking is to limit printer velocity to 100mm/s.

kubik · Jun 21, 2023

A kind of a random idea (in reality not random, because it happened to silly me): did you tighten down the motors in the motor holders?

Regardless, the motors really shouldn't be run at 1.1A. That'll dramatically shorten their lifespan.

Let's not get me started about my 2-year-old 2.4 formbot kit build; it has a full rebuild in its future where everything that is "generic" gets replaced; I can't even find the Spec Sheet on the motors. So many things that are just F(&*(&*ed about it

minduim · Jul 3, 2023

Hi
I just has the exactly same problem, and its really sounds like a knocking sound...but wasn't...it was extruder clicking sound.
I figure out and solved the problem just increasing a little bit the extruder backlash (gear mesh) and increasing the extuder current to 0.7amps.

Hope it helps.

djeZo888 · Aug 26, 2023

Not sure if you fixed this problem already, since it is an old topic, but I noticed that you have defined "step_pulse_duration: 0.000004" for just one stepper. This is wrong. You have to define this value for all or for none. Hope this also helps you out. Good luck.

dimky · Aug 27, 2023

Hey djeZo888.

Nope, not fixed yet. I like this printer, it prints good but this bloody sound is still there.

Thank you, I will check your idea and will report back once will be back at home.

Hiprex · Sep 5, 2023

Fixed by adding 'stealthchop_threshold: 999999' also to to [tmc2209 extruder].

SeaDog · Oct 7, 2023

Was watching a video today and the guy had stealthchop turned on. He said there were some loud clunking noises so he turned it off (to the "louder" mode) and the noises went away.
