I do put my IPA and resin outside on my back porch for a day or two to guarantee it's all cured before I strain it out. Don't really see the harm in that.

I'm upgrading my hotend from v5 to v6, and I have an assortment of misc cheap brass nozzles in all the sizes (which have been just fine). What's the deal w/ v5/v6 nozzle compatibility? I know most, maybe all of them were advertised at v5/v6, and I think v6 is backwards compatible, but do I need to worry about v5 nozzles going onto a v6 hotend, if I have any? Google isn't very helpful here so I'm probably overthinking it. I'm getting some nicer nozzles for everyday use (what's the best bang/buck here?) but I don't mind having odd sizes of throwaway nozzles around

Sure, just ignore all of the OSHA/EPA/NIOSH/etc. since 1953 (for IPA) and the 1970s (for uv-reactive resins in all applications, not just 3d printing). People take it for granted that doing these things is safe/fine/whatever because the materials can be easily bought, or because they don't personally suffer immediate negative effects, but on the industrial side of things there are literally decades of people suffering grievous long term exposure illnesses because they didn't take storage and disposal seriously with these very same chemicals. All I'm saying is this: don't minimize the severity of what may happen to someone's health however many years down the road if they don't take chemical handling safety seriously now. We're talking about accumulating effects, not single incident exposure effects.

Fair enough, I was under the impression that it was safe even long term. What are the risks I should be mitigating? My current approach is what looks like big cookie jars with a locking clasp and gasket on it. When not in use it's sealed, when the IPA gets cruddy I put it on my back porch for a few sunny days, pour the clean stuff off the top into another jar, then get a coffee filter for the not clean stuff to strain out the remaining cured resin. Let the IPA evaporate off the coffee filter then that goes in the trash, and the cleared IPA is set for a new round of cleaning. All of these steps are done with nitrite gloves, a long sleeve shirt and a full-face "spit guard" mask. I freely admit I have not dived in to OSHA/EPA/NIOSH stuff. I probably wouldn't understand it if I did, so what deficiencies am I exhibiting?

All of these steps are done with nitrite gloves, a long sleeve shirt and a full-face "spit guard" mask. That's a better question for either someone else that is familiar with your local toxic material disposal regulations or directly to your local EPD. Like, here in Georgia there are very few toxic waste centers to go to, and the ones that are available will charge you for disposal. The EPD's policies basically say any 3d printing hobbyist that chooses to utilize resin-based technology is responsible for long term storage of any waste materials/byproducts from 3d printing due to the lack of any way for the state to dispose of them, and that if those chemicals end up in the household waste landfill, or groundwater system, and can be traced back to that hobbyist its will result in fines and a felony charge, so I don't gently caress with resin prints (not worth the risk). EDIT: Especially not since SCOTUS just ruled the 6th Amendment no longer applies. Some Pinko Commie fucked around with this message at 16:08 on May 24, 2022 |

Cured resin is no longer toxic. The chemical reaction is over. It's non-recycleable plastic.

Sydney Bottocks posted:My guess is that most people treat it like when other people manually change the oil in their car on their own, and just dump it in the trash in the dead of night. Fun fact, in Japan (where they incinerate most of their garbage due to space concerns) they sell DIY oil pans that are basically carboard boxes lined with a plastic bag, and some absorbant stuff inside. Once you've drained it, just seal it up and chuck it in with your burnables rubbish, and the city takes care of the rest. It felt really weird the first time I did it.

Forced induction furnaces turn oil into water vapor and CO2 pretty cleanly, and scrubbers should take care of most of the metal vapors.

Yeah I was shocked we don't even have facilities to handle oil contaminated coolant. I was told to take it to jiffy lube and even then they looked at me funny Lacquered gas has to evaporate or be burned. And those items are/can be/ in every house! We don't have any safe or legal way to deal with hazardous materials.

Ender 3 pro. What slicer settings should I look at to clean up my prints? I don't have a recent benchy, just this test print from last night that looks especially sausage-y  I'm not sure how to share my slicer settings without vomiting a half dozen more screenshots into the thread, but this is gst3d pla+ at 200/50 and 0.28mm.

I printed way to many benchmarks in the beginning until I started noticing that most of those situations don't even happen. If you don't plan on printing things with inset text in those font sizes, I wouldn't bother.

 First layer woes continue. I had it nice and level, but kept having adhesion problems randomly. I did a 5x5 grid (top 4 rows pictured, the others are great) and got these results. My bed level is only off by variance of .3, but that enough that I can't get good adhesion without crashing the nozzle on higher layers.

Ethics_Gradient posted:I haven't gotten around to setting mine up yet, but the fact you can run Octoprint on an old Android phone (sparing yourself an RPi + camera) seems to be very much undersold. I think the main reason it's undersold is that there's a lot more uncertainty whether it'll work and how much fiddling it needs. The phone can't draw power from the printer, so you need: - a USB-OTG power/data splitter, if you have a phone that supports simultaneously charging and acting as a USB host (not all do) - or a wireless charge pad you can strap to the back of the phone, if you have a phone that supports wireless charging (most don't) - or a degree of comfort opening up the phone, removing the battery, and soldering an external power supply directly to the phone's motherboard. None of these are particularly expensive, but it adds more complication than "get a $15 rpi, flash an SD card with this image and it boots directly into octoprint". I do think it's worth a look if someone does have a spare android phone lying around, though.

It will also run (and is officially supported) on the Pi zero 2 W, which is why I picked that $15 figure, yes.

This site tries to locate Raspberry Pi stock but it's pretty barren out there. https://rpilocator.com/ It's easier to find an older Intel NUC or other x86 tiny/mini/micro computer on ebay for <$70 these days, and while they're often more than you need, it's hard to argue with the price. The android thing seems alright for older phones as well. I know some folks were getting OrangePis or other similar Pi-offshoots but there are a lot of them and I don't know which ones are available and easy to set up.

Seconding that Klipper runs great on a Pi 2 despite not officially being supported. The server takes longer to boot, but otherwise it's as snappy as my Pi 4 was. It worked fine on a Pi Zero W(original) as well, but definitely was slower and it was pushing it with the boot time. It works in a pinch but I wouldn't recommend it.

The cool thing about using a raspi instead of a phone or an x86 machine is having easy access to the header pins. Mine's set up to turn lights on when I start a print job and has a couple of (broken) temperature/humidity sensors (I'll replace them someday) plugged into it. The enclosure plugin puts that stuff right in the web dashboard. Obviously these aren't a killer feature or anything, just super neat imo. You could do similar things with a small form factor PC and an arduino or whatever but on a pi it's as simple as "plug the thing in and tell the plugin what pin you used"

Yeah, they mention that the Pi ZW2 works fine but the original Pi ZW has serious performance issues, especially if you try to add a webcam. I'm just running mine off an Rpi2 with a USB webcam attached because my ZW2 is stuck to the kitchen window recording a timelapse of the garden. cephalopods posted:The cool thing about using a raspi instead of a phone or an x86 machine is having easy access to the header pins.

Oh, that's potentially useful more generally, I have a few temperature sensors I've connected to SBCs lying around the house but some of the SBCs (the NTC CHIPs, specifically) are super flaky and constantly drop off the wifi I could swap the sensor for that room over to the octoprint server and scrape it with munin ToxicFrog fucked around with this message at 20:34 on May 25, 2022 |

biracial bear for uncut posted:There is no legitimate use case for acetone in an FDM process and anybody that recommends using it for any reason to post-process FDM prints is at minimum an idiot and at most maliciously evil. My hot tip is that if you're printing with PLA and are jealous of that acetone-smooth ABS you can use dichloromethane to achieve the same smoothing effect. Don't shout at me I tried it once in a laboratory fume hood and disposed of the used DCM properly. It was kind of a pain and I don't recommend it even if you do have access to a proper lab.

What is the best/easiest method or gadget that allows WiFi storage and access for a printer? If I try looking for a combination of the words WiFi and storage or something it's all $700 media servers and NAS arrays and stuff when all I want is some kind of storage I can write slices to over WiFi that is accessible by USB so the printer can pick it up.
