Not sure what you're talking about.

@@mghumphrey you have a video from a year ago of a voron trident making some noise moving, the comments are disabled on that video and this is the most recent video of comments enabled.

@@JennaToolls Oh, ok! The noise turned out to just be motor resonance for the A/B stepper motors. I changed homing speed and don't notice it much anymore.

i think so too so much hype on these things on you tube just got one quality is so bad my anycbic MEGA is so much better.

It’s just an over tightened belt. This is a new low IQ record for the general public

Yeah, I printed an alternate x-axis idler holder. The Prusa design has a flaw that lets the idler tilt, which is what was causing the issue. It's very quiet now, and the the belt doesn't twist anymore. Here is the STL file: www.thingiverse.com/thing:2939488

@@mghumphrey did you had to replace the idler or simply change that part ?

Erica May Manangan that's definitely possible.

Glen - thanks. I think you are right. I had the extruder cover off to work on x-axis belt tension, and while I was in there I noticed that the belt wasn't fully seated in the holder. I think this was enough to give the belt a slight cant, as when I corrected it and reassembled everything, the noise is now gone.

Thats good news. What do you think of your prusa i3 mk3, do you enjoy it? I'm currently running a prusa i3 mk2s but I'm thinking about upgrading to mk2.5 or even buying a mk3.

I am not very happy with it right now. It was not really ready when they released it, and there are still issues even today. For example, the way that it measures height above the bed (the PINDA probe) is temperature sensitive, and although they have the hardware in there to measure the temperature so that they can compensate for this, there are bugs in the algorithm and so this doesn't work. This leads to inconsistent first-layer "squish". Also, they rely on measurements of the bed height at various points, and then try and compensate for this. However, this just isn't working well, so you get inconsistent prints depending on over what area of the bed the extruder is. The instructions didn't mention that the bearings need to be cleaned of the rust-prevention oil and then greased, so now I will have to take everything apart again and do that. Honestly, I wish I had paid half the price and just gotten a Tevo Tornado.

I know how steppers work, and I understand now that it's "normal" for this printer, but it's indicative of not very good circuit design on the part of Prusa.

Hi danny. I will give you an email.

thanks for the response! i emailed you back sorry about the delay

Hey man! I am not sure if you found out the answer yet, or not. It is not that hard to make that happen! Since it is a raspberry PI, you can just attach an USB microphone, and make a little python app, that looks for any type of sound. The calibration process, may need some time, because, if the dog walks around, depending on the collar or other factors, there may be some sounds. Maybe you can play around with pattern recognition and try to record some of the sounds that your dog makes. Still, to be triggered from time to time if there was no sound, that is not hard, but there are many variables, to make it function properly, if you just want it to work, if your dog hasn't been barking or howling for a longer while. We can recognize the sound differences, and also our brains filter out what we want, or don't want to hear, but for a computer it is just electronic impulses. Hope this helps, if you need more specific directions, feel free to give a reply!

Matthew Humphrey I'll send you the schematics of the design I had in mind, in case you tried similar and it didn't work, if you don't mind giving me some input on it.
