Can someone do a VFA test with Basic PLA and post it here? The one from Orca would be great. 40 to 220mm/s, but would be cool to do 20mm/s increments instead of 5mm/s.
Curious to see how the new machine compares vs P/X series.
Thanks

Bump… nobody printed such a test out of curiosity?
I have one arriving in a few days, and trust me that will be one of the prints I run following my X1 experience. I’ve got all my fingers and toes crossed it’s better. 
I will post test prints when i receive mine, feel free to leave suggestions
Appreciate you both. I’m at wits end with support on VFA on my P1S.
@Wolfy1 regular orca slicer VFA test. go from 40 to 220mm/s.

I set up a test file for 50, 75, 100mm/sec.
H2D Manual VFA Test by Mike Jackson - MakerWorld
I was forced to make a manual test because Bambu Studio didn’t allow the height modifiers with the dual nozzles (a bug I believe). Mine was clean at 100mm/sec.
It was very consistent through 0, 30, 45, 60, and 90 degrees. Only light VFA across the test areas.

Here’s the 50mm/sec test
I didn’t photo every angle, but they are fairly consistent.
0-90 Degree
30-60 Degree

Appreciate the help here man!
Questions:
- on the red one, is it the image that shows some lines there? They don’t seem to be VFA
- on the grey one, do i see some VFA at 30-60?
I have a model that i can send, it’s bigger though. Support gave it to me, and i changed it a bit. It goes 40,60,80,100,120,140,160,180,200

My results show pretty darn bad VFA at 40, 60, 80, 100 (worst), 120 (worst). 100 and 120 are suppose to have severe VFA, so that’s OK, but 80? 60? 40??? 140 and up it getts better, but not clear. This is the 3rd P1S that they gave me, i’m tired of this. Now i have to replace belts AGAIN.
I’ll give that file a try (it slices fine), but if I look back on the numerous prints, I’ve only seen VFA on one print. Sure, if I look hard enough, I can find it on every print, but it was only clear on one.
My P1S was excellent with VFA too. Its just not a problem that I’ve had to worry about.
And yes you are right, the red one shows photo moiré not VFA, The VFA is extremely mild, almost undetectable. But honestly, the black one is also, almost undetectable. I can find VFA, but not enough to worry about it.
On this file… I thought VFA tests require surfaces that are not perpendicular to the basic x or y axis? Or is that not always required?
You are right. That’s why the orca has all those angles. But, support thought to send me this and i just changed it. My point is that, for my P1S, i see terrible VFA especially on X. So in a selfish way, i wanted to test apples to apples 
But, i really think the true test is the one in Orca. So i would do that. Start at 40, end at 220, do 20mm/s steps, see how it goes 
And TY again!

Ok, I printed it, but it’s almost perfect. I can find VFA on the surfaces, but it takes extremely close examination. Also note, there may still be an issue with the file in Bambu Studio. Studio only sliced up to 120 mm/sec and the rest of the model printed that speed till the end.

I would say the moire worsened pictures look almost 2x worse than in real life. The part requires specific lighting and close examination to see the artifacts. But it must be said the exact pattern is present, even if the moire appears to accentuate it.
So I’ve printed it as well. Caveats first, esun PLA+ in black with absolutely no tuning, just default bambu pla profile. I set the machine up, did all the calibrations, updated the firmware and then couldn’t be bothered to run calibrations again, I will do this tomorrow. So this is black PLA, the worst possible lighting I could manage, and I really tried to show off the VFA’s. They are definitely there, but nowhere near as bad as my X1C was, and it looks better in person.
Now I think this is a better example. The cube on the left is the H2D and the one on the right was my X1C. Obviously ignore the moire effect from the camera.
The included 20 minute benchy had a weird effect on one side, but this could be the model, as it’s only that part, the rest looks excellent.
Is it perfect, certainly not, but I’m much happier with this than I was with my X1. After 2 days I was boxing that up to return for a refund. This is a much better starting point and I’m sure it will get better with me putting some effort in and future firmware upgrades.
It’s also much easier to live with. It’s a lot quieter and doesn’t sound like a bag of spanners.

Guys,
Thank you! BOTH. @Supa_Koopa congrats on your new printer. The reason i would buy it is just PLA/PETG supports and hoped better VFA.
The cubes - def better in terms of ringing. But that might be due to accelerations and different components. But what a huge improvement there.
VFA though - holy ■■■■. 40, 60, 80 look crazy. I’m a bit shocked that with the belts upgrade and other internal parts upgraded this is still as bad as it is. Sure, i understand is the lightning angle or whatnot, but they are still soooo clearly visible (great pictures btw). Hmm hmm hmmm … and hmmm again.
For the love of god, i still don’t understand why not having an option with all tooth pulleys. Why?
Yeah it’s funny, they are a bit worse than I was expecting after how good the cube looked, but I’m not as upset as I thought I would be. It’s definitely better in the flesh, but as you’ve had so much trouble with the P1S I’m not sure you’d be happy as I guess you’re looking for completely clean prints now. I think because I’ve had a few months out, and I’ve looked at every printer going, I’d resigned to never having a completely clean vfa free core X/Y printer. This has so many more benefits that I can overlook the slight vfa’s I can see on this test
I’ll do some more testing over the next days and I’ll keep posting if anything relevant shows up, especially on proper prints.
I tried to get away with Orca and setting “do not slow down outer walls” setting. And, for the most part, it gets the job done, just some overhangs HAVE to be slow down to 40, and that’s where it stands out.
I kind of gave up in my mind, i just wished there would be an easier way and a CHOICE for us to swap the idler to tooth pulleys, as i saw in a different thread that it might have much better results. I might just try that one day… But, i would love to see this as an option. I would rather replace my belt EVERY month, rather than seeing all these VFAs tbh.
On the flip side, Creality K2 Plus, on their main page have a video that claims NO ringing at any speeds. Even though, in that video, if you loooooooook closely, there’s going to be some VFA i believe, but def looks way better. So i wonder what they did. That’s a bold statement right there. Don’t get me wrong, i heard horror stories about Creality in general, especially their support. But, there’s gotta be a way from both software and hardware to make these way less prominent. For a $2,000 machine and after waiting for soooo long, i seriously expected more. Would i accept those VFA’s? maybe. Would i be pissed to see them? Most likely.
I can certainly understand that, as there are definitely vfa’s on mine at certain speeds and some can be bad depending on the angle, but I think I can live with them. The orca vfa test can look worse on some of the angles, 30 degrees especially. But, I really went out of my way to make them look bad and I think most of the time they won’t bother me as soon as I stop using shiny black plastic. I think the K2 is probably better due to their closed stepper motors, and if you look back in the ‘speculation about new printers’ thread someone kindly did a vfa comparison for me. They did a X1C, K2 plus, plus 4 and an XL. The K2 did really well.
I was really close to buying the K2 on many occasions, it was some of the horror stories that put me off a little, that and the lacking customer support, apparent inability of being able to return it if it’s faulty and there being no spares at all in the UK.
The thing bambu does well, if you ignore the walled garden bit, is making everything accessible, makerworld integration, useful handy app, etc, etc. The fact my daughter can look on her phone and send something to print demonstrates the ease of access I appreciate. I also like being able to go on line and order whatever I need all at reasonable prices. This helped me to stick with them. I like to tinker but I also just want to be able to just send it when I can’t be bothered.
I hope you get it all sorted out.

I 100% agree with you on most of those points. That’s why i want a Bambu printer, not anything else. Plus in US i can get almost anything in a few days, so it’s crazy good.
But, i still can’t believe a $2,000 (now $2,700) printer still has VFA at 60mm/s.
There’s something about the VFA that draws my attention and my OCD goes wild afterwards
