I made a model of a Uilleann pipe chanter based on historical documents and now I don't know how I am going to print it without cutting it into quarters. It's 350+mm tall and has overhangs all over the place. Any ideas? https://www.printables.com/model/167672-uilleann-pipe-chanter e: I have an Ender 3 v2, 230x230x250mm cruft fucked around with this message at 01:23 on Apr 11, 2022 |

w00tmonger posted:Anyone check out anycubics new feps? They look frosted and I'm wondering how it affects strength/exposure ti e/etc The general consensus is that it's probably a more scratch-resistant surface, and a couple of YT reviewers have said that it doesn't affect exposure times at all. It appears to work on the same effect as some types of frosted glass, in that when it's wet you can see right through it.

Well my Voron is happily printing a bunch of PLA latch panels and is in it's final home. Now I just need to find a way to mount a monitor out here somewhere so I can tuck the laptop away.

So JayzTwoCents showed up on my Youtube frontpage, something about getting a printer. Turns out it's a LulzBot Workhorse. Some bog standard bed slinger, partially made of 3D printed parts, running 8-bit Marlin, still the loud as gently caress A4988 and it seems generally slow out of the box. Then I looked it up, it sells for nearly 3000 bux.  lolwat

I am really tired of compiling Marlin. I should have just left the runout sensor to fail as "filament present". The number of times the janky printed JST-XH connector has come disconnected is far, far lower than the number of times I have recompiled the frickin' firmware to fix this one drat thing.

Printing some wet palletes to sell and I was wondering about filament. I was initially thinking I'd use Petg, but given how little water exposure is happening, pla or some variant would probably be fine eh?

Sure, if you want to deal with unhappy buyers having paints seep through their palette. Coat them with an epoxy after printing and go nuts with PLA, just make sure to have "hand wash only" embossed somewhere. Print one, then set it on a towel and put some watercolor paint in it, then see how long it takes to seep through. You'll see what I mean in less than thirty minutes, doesn't matter what filament you use.

To my knowledge, if your top layers are printed well and you have 3-4 walls, that at least does the trick for inkwells etc. I know people who have used Petg in aquariums long term, but given no animals are involved and it's not sitting in there long term I wonder if it might be overkill

By long term breakdown, do you mean of the filament itself? PLA won't break down in anything short of a long vacation in an industrial composter. Anecdotally I have PLA prints that have lived outside for years (long frozen winters, bright hot summers) and are still trucking fine. e: Other than sun-bleaching of the colors

I guess pla should be fine then as long as I handle my walls etc properly and have a good seal Going to make some test prints tonight to verify, but I can't imagine pla would be an issue w00tmonger fucked around with this message at 19:59 on Apr 12, 2022 |

If you're making more than one of those, just vacuum-mold it. It's surprisingly easy to DIY.

I own a small prosumer vacuum former & have done small manufacturing runs, and even with everything done right you still get occasional duds. Like for example, you might end up with a bit of webbing in a tricky corner (because you heated the plastic a weeeeeee bit too long or whatever) and that means the result works fine but looks ugly in that spot and it's nothing you can "fix". Even if the results are good for the forming step, you now get to cut out the formed piece -- and it can be pretty hard to do that and have it look good and professional in the end depending on the shape etc. The formed piece is usually basically an awkward 3D shape with an inconvenient amount of wiggle in the material, and you're trying to make perfect ruler-straight cuts on it? Uggghh. (In a real professional shop with real equipment, they'll snip this out with a custom-tooled machine that gets it right every time.) In short thermoforming is simple in principle and you can get 80% of the way there in a small shop, but man that last 20% is a bitch. There are a lot of different ways for a formed piece to go south, and any one of them means the piece basically ends up a dud if you're after a professional-looking finished end result.

Shamelessly crossposting from my kiln casting thread, in case anyone finds this useful. I've been playing with my Saturn S for maybe 2 weeks and still have occasional issues, but I'm getting better every time. I was trying to print this pattern and for some reason, probably poor support, the last part to be printed cracked:  Rather than giving up all hope, I washed the print off in IPA (residue pictured above). I then applied some uncured resin to the crack with a q-tip. I closed the wound with a C clamp and popped it in the cure station for 5 minutes. I then removed the clamp and cured another 25 minutes. This matches the 30 minutes I've been using with this resin. The surface had a raised scar from the fresh resin and surface scuffs from the C clamp. I sanded it out, starting at 180 grit and going down to 2000 grit. Here's the finished result, alongside another pattern.  Some visual ugliness, but I don't care - it's a pattern. It's dead smooth and looks watertight. Likewise, if you were going to paint it, you might be able to salvage a damaged print. Or glue two or more prints together.

Anybody ever see this before? It's still printing, and in fact I can still access the "tune" menu if I spend the mental effort to parse the rotated & mirrored text, but goddamn.

I want to reduce fan noise on my Ender3 and think I'm going with buck converters and 12V fans (except if someone can recommend a better way). What I haven't figured out yet is the cooling fan. The speed is variable, is that done in a way that will work with any buck converter? Or does the converter need to be special in any way to do that?

The Mini+ kit I ordered on 12/23/21 was on the porch yesterday. Spent about 6 hours last night building it. I love these kind of projects. It initially failed the z-axis test, so I loosened the two m3x20's that hold that trapezoidal nut secure. I noticed that one of them was difficult to thread so I took it out completely. Looks like we have a stripped m3. I have a spare of those square nuts that it inserts into, but I'm not really looking forward to the amount of work it will take to get to it.

What I haven't figured out yet is the cooling fan. The speed is variable, is that done in a way that will work with any buck converter? Or does the converter need to be special in any way to do that? I think the fans are controlled via PWM can you just modify it in firmware? Might even be dynamic based on gcode criteria and machine state PWM changes the effective voltage by changing the average time full voltage is on, and depends on inertia of the fan to modulate
