There is rigid foam insulation that I cannot imagine a home depot failing to stock Also the fred meyer here has huge chunks of foam in the outdoors section, I assume for camping.

Wondering if there are some vendors I wouldn't know that carry this type of product. I used an old memory foam mattress pad. You can probably get enough from a cheap memory foam pillow at Walmart, too, but that might not be flat like a mattress pad. The pad I used was like 2" thick and squished down to 1/4" inch.

Home depot has a pretty great website, relative to most stores, in that it will not only tell you what they have but how many are in stock and WHERE IN THE GODDAMN STORE THEY KEEP IT as opposed to asking a minion who may or may not know what you mean. I would probably chop up and layer a cheap sheet of this stuff until it was the thickness I wanted https://www.homedepot.com/p/R-Tech-1-2-in-x-48-in-x-8-ft-R-1-93-EPS-Rigid-Foam-Board-Insulation-320810/202533656

The stuff in that video is not rigid polystyrene insulation foam!! It is open-cell polyurethane foam used for upholstery and such. It's squishy. This is the stuff that Home Depot sells in that category: https://www.homedepot.com/p/FUTURE-FOAM-2-in-Thick-Multi-Purpose-Foam-10030BULK2/203837080 (it's what I use under my printer, with a paver I bought there at the same time, and it works well)

Yeah I don't know or care what somebody used in a video I didn't watch, there are plenty of options for foam insulation, I would err more rigid for things I'm going to be stacking bricks and electronics on top of personally

well in that case you would be stupid, since the entire point of the foam in this scenario is that it's soft and absorbs the vibrations of the machine. it is the spring in the suspension system that you are building (the paver is the damper). if you put the paver on top of rigid foam insulation you might as well just put the machine on the table.

Insulation insulates. What do you think you're trying to do to all those vibrations? Glad you had good results with whatever random poo poo you crammed under your printer though e: that high density foam is a good choice too

But the point of the mass, and isolation material just went so far over your head.... The point isn't insulation, the point is a "bad spring". The point is to separate, or decouple, the masses involved so they dont' transmit vibrations. It's isolation, not "insulation". You can use tennis balls, racketball balls, little rubber toy cars, whatever. You're looking for something with a fair amount of hysteresis, and is elastic. Insulation foam is exactly not that. However, since we're on the bad idea train, a few layers of fiberglass bat and a brick would work too.

Yeah, the foam is there to dissipate energy, not to isolate it. Bambu sells isolating feet, and they tend to just make the printer bob around even more since none of the energy is dissipated into the furniture.

Looking forward to your comparative analysis of foam performance since you're so sure. I'd grab some XPS scraps from my garage and try it if my printer was having that problem to be worth solving

Javid posted:Insulation insulates. What do you think you're trying to do to all those vibrations? Glad you had good results with whatever random poo poo you crammed under your printer though "Insulation" at the home depot store nearly always refers to thermal insulation. That's irrelevant here. As Nerobro says, the point is isolation from vibration. Two totally different concepts. Some soft foams happen to be good at both, but it's coincidence -- the thermal insulation happens because all the foam cells trap air inside, and the vibration isolation happens because the cells can collapse and deform. Aerogel is an excellent thermal insulator, one of the best we've ever invented. It is completely rigid and quite brittle and provides no vibration insulation at all. By your argument it should be the best possible thing to put your printer on to "insulate" it from vibration. But it would be about as effective as putting your printer on a firebrick. That high density foam from Joann is exactly the same material that I posted. Squishy open-cell polyurethane.

Wondering if there are some vendors I wouldn't know that carry this type of product. A rubber paver, right next to the concrete patio stones of which you also want to buy one, will do you just fine. Together, they cost about $12. The spring factor of a rubber paver is in the ballpark of a piece of rigid foam and is less of a pain in the rear end. You can see them under my P1S in this picture: (I spraypainted the concrete paver so it wouldn't get crumbly and dusty and lovely.) Also rigid EPS foam will absolute disintegrate under vibration if you give it enough time. Good luck with that. tracecomplete fucked around with this message at 05:48 on Oct 2, 2023 |

On my old printer, I used something like this: https://www.thingiverse.com/thing:5416970 Far more elegant than a paving stone/foam and it totally isolated any noise into the furniture.

I vaguely remember a youtuber doing experiments with pavers and foam a while back and concluding that a medium squishy foam did the most for noise and vibration. Not the hard kind that you nail up on your house and not the squishy kind you put in a seat cushion.

Not the hard kind that you nail up on your house and not the squishy kind you put in a seat cushion. which is more of a source than you've cited since being lovely about advice you disagree with itt. maybe it's not the best foam but that was never my position, just that I don't want to put a seat cushion under my printer, do whatever I don't care anyway. the leather stamp project continues to bear fruit.

You could also try out debossed stamps instead of embossed stamps. I've found that's a nice way to get very fine details if you don't have access to a .15 nozzle to put down tiny lines.

ImplicitAssembler posted:On my old printer, I used something like this: Those can totally work for some use cases, but consider how much slower and how much less intense the noise and vibrations are on a bedslinger that maxes out (if pushed) around 100mm/s and relatively pokey acceleration, versus a corexy printer that will slam the print head around like the filament owes it money. My SV06 was Klipper'd and I had it around 4000 mm/s^2 acceleration and it was still nowhere near as loud as a Bambu can be with the door open and just sitting on a table - and it didn't make me feel like the table was going to walk away mid-print. The paving stone weighs almost as much as the printer and gives it a lot more mass to push back against, atop the spring that is the rubber paver (in my case). tracecomplete fucked around with this message at 14:33 on Oct 2, 2023 |

Alright I’m beginning to think online advice for the X1C is a scam, because everything was telling me to keep PETG temps at 250C or lower and bed temps at 50C and I only started getting decent prints when I cranked the temps up to 265C and 60C. Still have a bank 4 filament feed issue to figure out, though. The printer regularly complains it can’t unload the filament and it’s either a tubing issue or the roll is just too big/smooth with the cardboard adapter I had to put on.

For the unloading issue try that elbow printable.

The stock PETG profiles for the Bambu printers has 255C for the material, 70C for the engineering plate and 80C for the high temp and textured plates. Not sure where you found that "advice", but it's pretty bad. If you're trying to use the cool plate... errr, don't, I think. I seem to remember reading that even Bambu doesn't recommend it anymore for ABS or PETG.
