That makes one of us. Fluid dynamics gets screwy.

I’m only going to be a pedant because that’s sort of the point of these conversations, that’s not a bad interpretation and I appreciate you posting it.
BUT, it’s not so much that it’s “distributed” as that, so long as the boat floats, there will be a mass of water displaced exactly equal to the mass of the boat. In this case it’s displaced off the bridge (off either end). There is zero force being applied up or downstream (except during the initial transition). That’s the fun thing about incomprehensible fluids, every infinitely small point at the bottom of a water colum ONLY has the force of the column above it acting on it. A pressure gage will read the same for a square mm or square m.
Spot on with the bowl though. The displaced water can’t leave the system in that case so the masses add.
Heres the action lab video BTW! m.youtube.com/watch?v=SUq_tM3yGTM&pp=ygUKQWN0aW9u…

Here’s a fun fact action lab pointed out: setting aside wind, etc, the load the bridge has to be designed for is only the water that fills it.
That bridge will have the same force on it from a tanker or a kyaker.
- Comment on FYI (opinion.) don't buy an MMU 2 weeks ago:
So I have a FlashForge AD5X with the MMU. It worked amazing out of the box, including flawlessly doing some TPU. They actually mentioned the MMU was designed with TPU in mind. That being said: I have been struggling with basic PLA, even after swapping to nozzle that has run only PLA (even though I only ran <10g of TPU through it). I am still new to a lot of this, and don’t feel experienced enough to fault the hardware. What I can say though is it does seem folks are specifically improving the ability of MMUs to handle flexibles. A big reason I got it was to be able to do ABS parts with TPU gaskets. Ask me in a few months.
- Comment on FYI (opinion.) don't buy an MMU 2 weeks ago:
Same here. Printing something like say, a cow, with frequent swaps would be wasteful, but I’ll do parts with 1-2 color swaps. It’s mostly nice as you said though to have multiples “locked and loaded” to do a 1 filament print.

2nd gramps. I spooled it up in about 2mins on an unraid server.
- Comment on Flashforge AD5X, how long do nozzles last? Premature wear 3 weeks ago:
So that’s what I thought… Except for similar issu s with extended drying.
I building an enclosure with a rotary dehumidifier to keep things low, but despite the tell tale signs I think something else was going on.
- Comment on Flashforge AD5X, how long do nozzles last? Premature wear 4 weeks ago:
Me to! I was almost done with a batch of prints for a friends fundraiser (30x hat looms for knitting. Great little project, they’re knitting hats for the premies at the NICU, so they needed a custom model for the tiny babys). I think you’re right. With the oozing and whatnot that has to be it. I brought up the fundraiser because it had me making multiple prints of the same file. When I found a setting that worked (moving to the 0.20), the first few worked, but were a bit stringy, but by the 3rd/4th one they were printing flawlessly.
I guess maybe when things got screwed up at 0.16 the nozzle had some funkiness, and with enough material it worked itself through? Still doesn’t explain why that brand new nozzle screwed up in the first place at 0.16 (which suggests the flow rate issue you brought up), but I’ll take the win.
- Comment on Flashforge AD5X, how long do nozzles last? Premature wear 4 weeks ago:
Thanks! This kind of insight is super helpful. Are you a poster here often? I was able to get decent prints again by changing the layer from 0.16 to 0.20. Still disappointed and confused as to what happened, but will probably keep the printer. Not sure if it makes sense to do a “wrap up” post for anyone else searching later.
Also: go team venture!
- Comment on Flashforge AD5X, how long do nozzles last? Premature wear 4 weeks ago:
correct. I initiated a return with amazon. I have had a 250g spool in the drier since about 10am today, and will try it this evening, but if that doesn’t work I’m just returning it.
In trying to do a cold pull (which you do in this machine by attaching the nozzle upside down and manually pushing filament in), it was oozing and popping with the remnants of the previous filament, which to me says very wet filament?
I had tried drying filament for ~8hrs yesterday with no good results. Is there something else that could cause the oozing issue? My friend brought up that maybe the temperature sensor isn’t working properly and it’s hotter than it thinks it is?
- Comment on Flashforge AD5X, how long do nozzles last? Premature wear 4 weeks ago:
I’m not sure if it’s the Z or gunk building up and dragging. Also with the new nozzle it’s been only PLA and no joy whatsoever.
- Comment on Flashforge AD5X, how long do nozzles last? Premature wear 4 weeks ago:
Thanks to everyone for the input, after drying a ~100g spool of PLA for 8 hours and having failed prints on the original nozzle and new nozzle I have initiated a refund.
- Comment on Flashforge AD5X, how long do nozzles last? Premature wear 4 weeks ago:
yeah I anticipated wear, but with <2kg of material that seems excessive no? I did have some feed issues, but even with those resolved and it feeding nicely, I still have problems. A friend of mine did suggest that maybe with the feed issues I managed to do something that brought the nozzle out of spec and that’s why I’m getting issues.
- Comment on Flashforge AD5X, how long do nozzles last? Premature wear 4 weeks ago:
No special filament, other than <10g TPU. Interesting I’ll try the test. I think I’ll get the dragging though, as I was trying to do some business card type prints that were basically what you’re suggesting and got issues. Sometimes the first layer would be ok, sometimes not. It would wind up dragging it around and as it was warm, it would roll the layer into a “snake”
- Comment on Flashforge AD5X, how long do nozzles last? Premature wear 4 weeks ago:
It was just normal PLA. The only special filament was some TPU, but that was <10g total.
This is helpful, I think it’s one of 3 things based on your input:
- Wet filament. That’s causing oozing/build up on the nozzle and causing dragging. Fix: Try drying like you mentioned.
- The hardware had a failure somewhere. Fix/Verify: ???
- The firmware is bugging and not setting the Z properly after calibration. Fix/Verify ???

Ah, I thought the date was announced like two weeks ago. My mistake.
But in any event hope you get some good time in with it this weekend. When the vibe is that unique there’s nothing like a second helping done right.

Yeah, this was one of those games that I could see the craftsmanship but just wasn’t for me.
But strong follow up to a much beloved original IP for a very reasonable price? That borderline shadow dropped? Love it, yall enjoy your suprise Christmas and go nuts. Cool as hell.

- Comment on Can/should I just use a networked folder as a duplicati backup destination? 3 months ago:
This is really helpful thank you! I think it’s samba share? Whatever Unraid has just baked in and calls “shares”.
Googling rsync that looks like it’ll work, and faster is better!
While I do want true backups of a few drives (as in: if a drive fails, restore the backup to a new drive, physically swap it out, and you’re good to go), the majority of the data I’m just looking to have it “backed up” (as in: all of the files are present in more than one location). The majority of the data is ~18TB of media for my plex server. My unraid is: 1x 2TB, 1x 10TB, 1x20TB and 1x20TB(parity). It sounds like Rsync-ing the 20TB drive with my plex media and the 20TB unraid disk would get me what I need?
Thanks for the pointers, getting a few things to google is incredibly helpful.

I recently talked to someone who’s small family business was in their 3rd generation of making these. What they said is that there was a big market in south east Asia.
Like we learned early covid, a lot of hygienic paper goods are made locally (not worth enough to ship), and they said that there just aren’t as many trees to make paper from there, so despite being very far away, this little family shop made and shipped these.
The person I talked to wasn’t involved in the business directly, so they/I might have some of that wrong but I thought that was interesting. Like I guess it’s enough to keep them in business but probably not enough to attract new comers?
