But they claimed to have used dilution formulas to achieve these percentages. Pretty sure it's BS.

papalonian ,

I know you can, I do the same haha. What I'm saying is, they couldn't have both accidentally read the 50mg as 50% while simultaneously claiming to have calculated exactly how much would be needed to dilute it to 49%, because diluting it to 49mg and 49% would be two different calculations and it's unlikely they'd make that mistake after doing the calculations.

Normally I am sad when I see these because my work and school schedule prohibits me from having an actual weekend.

But my semester is over and I managed to get some time off, so after this Friday, I've got a mini vacation set up!

Ahoy mateys!

If I'm not wrong, NEET = Not in Employment, Education, or Training

Anon felt bad about being a leech off of society so he slicked his hair back and learned how to ride a skateboard, and is wondering why he still feels like a NEET.

papalonian ,

I wonder if there are any examples of glyphs that depicted clear, unquestionable children/babies? Like, maybe a picture depicting childbirth, or another clear indicator that the human being depicted is meant to be a child. We could then compare the depiction of these "tiny humans" from this post to those, and see what the artist may have been trying to draw.

I'm not one to blindly believe in something just because their profile says doctor in front of it. For all we know, he is just taking the piss on a funny post. (Not that we're doing anything more serious, of course.) I just don't think that we should disregard the idea that these ancient people with known myths about giants may have been drawing a picture of giants just because they could have also been drawing something else.

Where to find online communities of people making stuff mainly as a hobby?

Stuff could be anything, digital or physical, but the idea is of discussing and doing it as a hobby without any pressure or push to make it a business or side-gig. Nothing against that, simply that communities/groups with that atmosphere are easy enough to find as-is.

papalonian ,

I just took a look at your how to video. Very cool. Is this a process you came up with, or did something inspire the idea?

If we talk about low-end China printers then the answer is they might not be as safe

Bambu had to recall one of their printers for a faulty bed heating wire that either was causing or had the high likely to cause fires. We have robots with flame swords that we've trained to not burn our house down. Yes some robots are better built or trained than others but it's still a robot with a flame sword nonetheless.

Qualified experts of Lemmy, do people believe you when you answer questions in your field?

The internet has made a lot of people armchair experts happy to offer their perspective with a degree of certainty, without doing the work to identify gaps in their knowledge. Often the mark of genuine expertise is knowing the limitations of your knowledge....

papalonian ,

Oh I love that. It happens a lot in political discussions when you don't 100% agree with someone's point.

"I don't think defunding the police will solve the issues we're facing" means getting called a boot licker and that every comment you've ever made that doesn't scream "I hate cops" is about to be linked to for proof that you're a Trump loving Nazi.

What, like Pandora, Spotify, etc is out there that I could add music I have on my phone/etc?

I've been using one of the Pandora services, but I've been getting a little annoyed with the stations (which I presume I would get the same annoyance from other services, too). So I'd like to be able to create a station and add songs that I own and that wouldn't normally be in that station. (And I know you can add artists to the...

papalonian ,

As someone else has stated, you can add music you own (or at least, music to which you have files for) directly in to Spotify, though I'll say the reliability is "ok" if you are listening on multiple devices. My guess is they don't host those files the same as the others. Maybe if you have a server or computer that's always on, you can put the file on that, and add it to Spotify on that device, maybe Spotify will just feed you the file from your computer

papalonian ,

I see, well if you're more in the self-hosted side of things other people have given some suggestions that seem like it would work well for your needs.

I used to have a huge collection of music I'd accumulated and only played files locally, but I've gotten lazy over the years and am a Spotify boy now. I will say that it's been irritating me to no end with how bad shuffle is; my main playlist has over 500 songs in it and I know there's at least a hundred or so that I haven't heard in months because Spotify's "shuffle" thinks it knows what I want to listen to more than I do.

papalonian ,

First guy is saying, "there's no point in trying to figure out the "answer to the universe", it's a lot easier to be happy if you just go with the flow".

This leads the reader to assume that he's got it all figured out and is a relatively happy guy, an assumption that is subverted when asked plainly, "are you happy?"

I don't know that there's a specific take away here, so much as it just being a funny quip in a larger exchange.

papalonian OP ,

I've never really had issues with wet filament. I primarily print in PLA, and while it's a pretty hot button debate, I lean towards the evidence of PLA not being effected by moisture. A user here ran an experiment and posted the results of leaving a spool of filament in a bucket of water for 24 hours and the running a print with it still in the bucket, I think they just put a sponge in front of the filament guide to get rid of the water droplets but it printed exactly the same before and after the soak. Ever since I saw that, I haven't bothered with bagging or drying any of my PLA outside of printing with it inside the enclosure (where humidity drops to single digit percentages during prints).

Of course, mileage will vary from user to printer to filament. But in my experience, with filament from a handful of major suppliers ranging from a few weeks to around a year old, as long as it's not snapping when I try to move it, it'll print fine.

papalonian OP ,

I'm sorry, what makes you say that haha

  • Dried filament and different colours, no effect
papalonian ,

Alright, bow out if you must.

Cringe, and implies you're trying to win an argument rather than have a conversation.

Also, I'm sorry, but you're totally wrong. I know what kind of intersection you're talking about, this definitely is not it. Maybe it's a regional thing, but XKCD is an American webcomic, these intersections are all over the place and you definitely are not supposed to stop in them.

Intersection

This is the kind of intersection you're talking about. You'll notice that the center area where the car turns is much longer than the area in the original post, in addition to having clear lane indications.

If someone were to stop in the intersection in the OP, they would have to be stopped at an awkward angle not parallel to either lane, and if someone were to follow them into the intersection, the second person would have nowhere to go.

Long story short, there's two different kinds of intersections being discussed here, regardless of whether or not you acknowledge it or which one you believe is being depicted. One of them makes the comic make sense, while the other does not. Which one do you think the artist intended to draw?

papalonian OP ,

Filament is not melting when held to the outside of the heat block. It is 100% an issue with the nozzle not reaching target temp.

papalonian OP ,

A PID tune is pointless if the printer is not reading temperature correctly. It is for gauging how much power to send to the heat cartridge, it does not effect temperature readings.

Yes, thermal compound was used in appropriate places.

I can interact with my printer via klipperscreen or the mainsail web UI. Both give the same temperature reading. I don't have any way outside of Klipper to talk to the printer.

I might try installing marlin on my previous board to see what the gets me, if anything.

papalonian OP ,

I really, really appreciate the time you've taken to try to help me, but I'm positive the hot end not reaching target temp is the issue. If I push filament against the outside of the heat block, it melts at a very slow rate, when it would normally instantly liquefy against the block.

I'll drop my config file when I get home.

My temp chart, both before and after the issue started again, are near perfect flat lines. PID tuning done on current hardware.

My hotend has a fan blowing on the cooling block, and two part cooling fans.

There are no clogs/ obstructions throughout the hotend. New hardware has been tested (nozzles, heat throats)

Typically I print between 60-120mm/s depending on nozzle size and the model. But not long before the problem started I successfully completed a tower print at 200mm/s with zero issues. It should be noted, though, that once again this is an issue happening outside the realm of print settings.

papalonian OP ,

Thermistor swap was done a few times on the old board when the same issue was happening. I had 3 of them that I was swapping between.

Currently in there is a pretty nice thermistor that, rather than using a set screen to keep it in place, is actually built in to the end of a set screw; it's effectively impossible to damage it. Unfortunately, it's a known-good resistor, my problem lies elsewhere.

papalonian OP ,

Good call on checking that resistance, didn't think of that before.

Even more frustrating is it happening twice across two different boards!

papalonian OP ,

Unfortunately, no.

papalonian OP ,

Yup, went over those a few times throughout the posts, multiple thermistors, multiple ports on the board, several configs in Klipper. All of them identical behavior.

papalonian OP ,

I did not, but yesterday I put marlin on the stock board (the first one to start doing the temp thing), and it's doing the same thing, so the pi isn't the problem.

I also tested the printer's power supply with my multimeter and it's stable between 23.8v-24.2v.

My house electricity is a little dodgy, my lights flicker for a half second when a high draw appliance turns on (AC, refrigerator, etc), but nothing in the house has ever been damaged by it in the 5 years I've been here, so I don't think it's strong enough to kill multiple boards, especially since it's after a PSU. I suppose moving forward I can run the printer off a surge protector (I was running straight from the outlet because I was testing power consumption a few months back and never switched it back).

papalonian OP ,

I'm sorry that I forgot to respond to your comment.

Unfortunately, everything you mentioned here is working properly.

papalonian OP ,

Haunted it is.

So it is.

I've ordered a new board to come in tomorrow. Once installed I'll run the printer exclusively off the surge protector, we'll see if we can't make this board last longer than a week 😉

I had the semi joking idea of designing a breakaway cable that would simply plug and unplug all of my printer peripherals into the motherboard at once. That way, when I break one every week, it's a simple drop and plug process.

papalonian OP ,

I have a new board coming in tomorrow that I'm 90% positive will work just fine. I'm running low on suspects for what could be causing the failure, but I'm going to take a few precautions with this one (using only a surge protector, for starters) and see if it makes any difference in longevity. I guess I'll make an update if it dies again, or maybe again after a month of continuous work. There are a few people that have been in every thread, I'm sure they're curious as well haha

papalonian OP ,

I'd be really surprised if slightly dodgy power would damage 2 unrelated boards in a super specific way and damage nothing else.

This is my thinking as well, but I've got zero other ideas.

I've already cut the wires on my heat cart and thermistors, so swapping those parts around is easy.

I've seen printers with a PCB on the hotend, but I'm not sure I understand what it is that the PCB does; is it simply a port hub between the main board and the hotend to make parts easier to swap out, or does it do any actual "thinking"? If it's the former, I think I've more or less accomplished this with the connectors. If it's that latter, I have no idea how I would go about configuring that to work with the SKR, but it would probably solve my problem by moving the "temp calculation" job off of the main board. It would at least tell me for certain if the board is what's reporting the incorrect temp.

Usually when I get into a relationship with someone and their kids have had vibes I immediately start abusing them, like no questions asked

papalonian ,

Don't let @Grayox hear you saying that. He may not like you speaking ill on his God.

papalonian ,

I think you're describing me trying to do 75% of my interests/ hobbies.

papalonian ,

How long have you been using this printer with it's current configuration? Has it been printing perfectly for months with no changes and then suddenly this, were there any recent upgrades/ updates, maybe a different problem happened and you fixed it but now this is happening?

Does this happen with every print, or have you only tried this gcode? I'm assuming you already know the model itself is good.

As a bandaid solution, you can fiddle with z-hop.

papalonian ,

I'll posit a (very poorly and drunkenly abridged) story from the Buddha that I actually think of on a somewhat daily basis, in contrast of all the Buddha-bad comments:

A man approaches the Buddha in the city. He says to him, "I hate you Buddha, you are always telling people how to live their lives and what they need to do to be happy, how can you have all the answers?"

The Buddha says, "I will ask you a question. If I give you a gift, would you accept it?"

The man says of course he would not.

The Buddha asks, "If you do not accept my gift, then to whom does my gift belong?"

The man says, "The gift belongs to you, because I did not accept it."

The Buddha replies, "Then I treat your hatred as a gift. You offer me anger, and I do not accept it; therefore, your hatred and anger belongs only to you, and only you may suffer it's consequences."

So when people get angry at me over things that are beyond my control, I reject their anger, let them yell at what they think is the problem, and move on.

Then the Buddha punches me in the face and I am enlightened.

papalonian ,

I don't think he asks that question in the original story. Drunk me was just giving him more dialogue.

I don't accept the IRS's gift

    After reading the bottom portion, I have to wonder which substance might this container be filled with 🤔

    AAAOOOOOOH! THAT'S GOOD ENOUGH TO GET TATTED ON MY BACK BROTHER

    I'll take $75 of my profits and buy a shit new bike whenever someone I can't beat up takes it

    (I cannot beat up many people. I would not profit from this model.)

    papalonian ,

    Depends on who's stealing it/ why. Could be stealing it purely for means of transportation.

    papalonian ,

    Plot twist: it's actually a nice, stolen bike that I buy for $75.

    papalonian ,

    I imagine this is the kind of stuff I'd do if I was retired and reasonably expendable resources. Goofy stuff that benefits nothing besides satisfying my curiosity of "can I do it?"

    papalonian ,

    I mean.. not really? I get the meme but there are a ton of merit badges you can do sitting in your room. I was a scout 15-20 years ago, I remember going through my handbook and doing all of the badges I was able to without going anywhere or buying anything in one weekend and asking my leader for like 15 badges the next day.

    Though I may have to correct myself, I think these were belt loops I was earning at this point, I don't remember the difference (I think the fancy sash comes a little later, at which point.. maybe my comment was unnecessary.)

    papalonian OP ,

    I see; though, a thermistor not making good contact with the heat block would imply the heat block is hotter than reported, not the other way around.

    This glass thermistors are a nightmare. I kept accidentally ripping the leads off mine. During this whole debacle, I treated myself to a fancy thermistor that is built into the end of an M3 bolt - it screws in to the hole meant for the grub screw that normally keeps the glass ones in place.

    papalonian OP ,

    Thank you for asking! I have a follow-up post here detailing what the actual issue was (incorrect temp readings from the printer, hotend only reaching ~half reported temp), but the actual root of the issue remains unknown. The board seems to have been the issue, as swapping in an SKR mini has fixed it (and improved a couple other things, definitely recommend this board!), yet I still have no idea what could've been the problem with the other one. It was relatively new, had been working for weeks, tested completely fine on a multimeter, and even read correct temps for the heated bed when the thermistor was plugged into the hotend port.

    In short, the gremlin did not move out, but I've bulldozed the house and built a new one around it.

    papalonian OP ,

    ... So you wanna know something brilliant.

    I replaced that board maybe 2 weeks ago and have been printing fine since then.

    About an hour ago, the new board has replicated the problems of the previous one. Not getting hot enough but reporting target temp. It's a completely different board from a different manufacturer, and it's failing the exact same way as the last one.

    papalonian OP ,

    Someone asked this in a different post of mine, all of the thermistors I used were a single piece, meaning that replacing the thermistor replaced everything between the pins on the motherboard and the unit that goes into the hotend.
