why am I VFA much worse on one side of a print?

Nice video but i it would be nice to know how are closed loop steppers are effeted by the belt tention ?

👍

Excellent video thanks!! I may have missed it but how do I actually set my belt tension to a specific lbs? Is there a chart that converts lbs to frequency?

How about CoreXY systems ? Can your calculator work with them ?

A better way of fixing this is just to rip out the control board and the stepper drivers and put in a better board with silent drivers. No noise from the drivers means no noise in your prints. That eliminates the need to replace all this mechanical stuff that truly isn't the root cause of the issue.

so basically, this video is an ad. Congrats, you just nullified everything you just said.

TLDR?

If the frequencies are known, wouldn't it be possible to noise-cancel the motor's vibrations in-slicer or even in the firmware? If the frequencies are variable, I feel some sort of calibration wouldn't be too hard.

Ok, but, what about any third-party reviews? I can’t find any

Toulouse is a City in France, no?

a motor tune couldve solved these issues

How do you accurately determine tension by pitch? I find that plucking a shorter section makes a lower sound for example. Also don't use ai voice pls. Sounds really cheap. We don't care if you have an accent or whatever just record with your own voice :)

Not a fan of computer voices

i mean 2 - 4 seems like a winner here, but it seems to be tested on snail printing speed. Everyone is pushing the machines to the limit where accelerations and deceleration are much bigger than what was shown in the axis simulator. In those cases your belt will start to slip on low tension.

Start of the video comment, under 1 min in. My method is use my ear and listen to the belt when plucked and run it and listen to the steppers. Run input shaper and adjust based on the results above. Lets see what they say.... I guess i am going to spend some time tomorrow messing around with my belt tensions and see whats best.

holy shit man this ad video was generated by AI three years ago , fascinating

loose belt definitely increase VFA, I spend days testing prints over 300mm tall, tightening belt will decrease VFA but cause layer shift on tall and narrow parts, while loosening belt reduces layer shift but creates VFA

Do these experiments apply to CoreXY printers as well?

Pretty good information, but I can't stand a computer narrating to me. How about an actual human.

Does the prusa mini use this motor? It’s completely absent of MRR

First All Aluminium V-Slot Profiles are the same so it can not be from frame... I am a engineer that has over 25 years of experince in Mechatronics.As you guys don't know what the problem is I can guarantee you the problem source is extruder gear alignment,hotend heat instability and even the same looking filament is not all same thickness every meter... 3D Printing is not a Precise manufacturing process.The nature of Additive manufacturing leaves the unwanted artifacts.Cause its nearly impossible to maintain every parameter same like filament thickness,hot end heat stability although the extruder gear shifting,pressure can be optimized but filament thickness shifting will still effect the quality...

Robot voice = Me not watching any video's on this channel

How about tensions vs speed, accel?

wow! That's amazing testing

thank you, this really helped!

*EVERY* video with synthesized voice gets an _automatic thumbs down!_ 👎🏻

G-code imput shaper is very interesing.

This is great content, but you probably see it in the retention rating that the text to speech voice over isn't going to do you any favors, I was basically out the door upon hearing it.

Possible to also attach these motors to say a Anycubic Vyper?

Can these motors be used on a voron 2.4?

Prusa be like🥱and then solving it him self while making bigger print resolution

This should have more than 52k views, it's great.

Get a real voice over and I might consider subscribing. Info is decent... But the annoying factor counteracts it.

Thank you for the video. I painfully watched it. I wont watch it again as I cant take that voice but the info was appreciated.

I hang a 20g scale weight from the center point of my X axis belts, then use the measurement between the 2 sides of the belt as a reference point to start with. For my Y axis belt, which is a vertical mount, I use a DIY 3D printed - open ended - wedge that fits between the belt and the rail - and use the deflection of the 2 sides of the wedge to get a reference point. As I run through prints, I use these reference points to adjust belt tensions. It takes time, but now I have a stable belt tension setup and my prints get great results.

Thank You sir

not all heroes wear capes

Extraordinary, well constructed and executed experiment and video script. Thanks for the contribution to the community. This video deserves more views and attention.

I wonder if my belt tension is causing my extrusions on top layers to be looking good one direction but bad when it travels in the opposite direction? I notice it when I print a brim.

I heard that dual drive extruders make this problem worse. That's been my experience. My single drive older extruders were better than the upgraded ones when I bought the same printer years later.

I get MRR at standard speed on my MPSM V2

Need to update this for corexy printers.

could you please share the value of “belt test” in mk3. For normal user . We are hard to measure the lbs of belt like3.5 or 4.5. Thanks a lot.

Excellent. Thank you.

If you want anyone to ever watch your videos you need to hire a real voice over person. This robot voice is unbearable. I cannot watch past the 20 second mark without wanting to die

Very nice for voron v0! Looking forward to upgrading my motorsa

Yeah, it's not just crime and drugs. It's corruption, nepotism and poverty too. Really really deep poverty too.

Not straight to the point!! It should be a 50 seconds video, you're very good, you should have two channels, one straight to the point, and this one for those who like expert settings

So MK4 solved the problem by using your motors? Nice... 🤔
