In the given example, is the gas station not forcing Customer B to purchase more gas than they may want or need? What if I have a chainsaw with a 1 gallon fuel tank? Now I need to not only buy more gas than I can use, but a container to safely store it in. (It’s also illegal to dispense gasoline to/from an unauthorized container!) Now if I use my chainsaw once or twice a year, I also get to dump out that extra gasoline because it’s gone bad by the time I need to use it again.
You know like the kind that go on a window or bathroom mirror or on the wall or in the shower. They need the atmosphere pushing down on them to work, right?
This only works on “virgin” metal iirc - if it’s been exposed to Earth’s atmosphere, it won’t work. If you shave off some from the surface I believe it works again.
I didn’t realize that the layer was thin enough to rub away with minimal friction. I’d learned about this years ago so I could be misremembering things, but the source I read made it out as if it wasn’t a major concern with space exploration because it took substantial effort to cold weld things that had been exposed to air.
This is among the things I did today that finally nailed the temp issue, I used a config file from last month when it was working and there was no change.
I took am certain it’s software/firmware related. I’m also not an expert, but over the course of the last few days I’ve learned a lot more than I knew, and I’m pretty confident that at least everything I’m able to edit (or at least everything the average user is intended to edit) is set up properly, which is why I feel I’m running out of things to test
I’m actually on my third heat block! (I replaced the stock one, then broke a heat break inside the thread and had to order a third.)
That’s a super strange problem that you had. I had a similar one with my printer a year ago on the stock firmware where I randomly had to adjust the stepper as well.
Also, IIUC, PID settings are more about how much power is going to the heat cartridge to ensure the temp doesn’t fluctuate or overshoot. Even a terribly configured PID setting should not effect the temperature the printer is reading, let alone by almost 100c in some cases.
One thing you’re overlooking here is the connection between the hot end and the control board.
The Neptune 3 is a ghetto ass printer that doesn’t have a hotend control board. Haha. There are separate wires for the heat cartridge and thermistor that run all the way from the unit to the printers motherboard under the bed. Since I’ve swapped thermistors multiple times, I’ve more or less confirmed the connection is good.
Frankly I’m impressed you’ve managed to troubleshoot this far.
Me too! Haha. I would normally have long given up, but I’m DM’ing a DnD game, and not being able to print out minis, terrain, obstacles etc is actually having a larger-than-I’d-like effect on things.
I suspect an electrical issue on the motherboard. What happens if you swap the bed and hotend thermistor, and/or plug one of your reference thermistor into the bed input?
This is one of the tests mentioned in my post:
I also feel the motherboard can be removed as well; there are three pins for thermistors, all three show accurate readings for the bed but identically inaccurate readings for the nozzle.
As to your other two points, I myself know very little of reading electrical signals, but my EE friend was over earlier today helping with troubleshooting and he verified that nothing on the board was reading out of the ordinary.
I actually did just try reflashing Klipper to the board yesterday and it didn’t do anything, I haven’t updated Klipper on my Pi in a little while, but I can give it a go when I get home tonight. I do have a spare Pi, but it’s kind of a pain in the ass to rebuild everything on a new system for a high likelihood of not much changing
Yeah, I knew from the getgo that the IR thermometer was only gonna get me within a wide range of accuracy. (Hence resorting to more empirical testing like boiling water in the previous post, haha.) I was only using it initially to get an idea of where it was.
After posting yesterday I went out and got a high quality probe thermometer. I was actually lucky enough to get one who’s probe is the same O.D. as a Bowden tube, so it friction fits inside my hot end. It took a little while to find the exact spot in the probe that reads the temp, but I was able to dial it in last night to where both Klipper and my probe read exactly 200c. (Before adjusting anything, Klipper would read 200c, IR would read ~90-130, probe reads ~170.)
I’m not familiar enough with electrical components/ readings to determine anything myself, but I had a buddy over yesterday that was helping me out who went to school for the stuff and is very well versed with 3d printer diagnostics, and he verified that nothing on the board is reading out of the ordinary. I considered a new board, but the board I’m using currently is itself relatively new (just had the manufacturer send me a new one after the original died; new board has been working for ~2 months).
I’m using a 3950. Funny thing, all my previous thermistors were also 3950s, but Klipper has always been set to the EPCOS 100k sensor. Looking them up, there should only be a couple degrees difference between the two, and changing between the sensor types didn’t do anything for me, so I don’t think it’s that.
what motherboard and hotend
It’s a robin nano 2.1 mobo, not sure what you mean by “what hotend” it’s a Frankenstein of various heat blocks, heat breaks, etc. not an all-in-one or anything like that. It’s been rebuilt probably a half dozen times during the duration of this issue; I’ve confirmed the issue has nothing to do with any of the physical components of the printer (ie stepper motors/drivers, loose connections etc).
Precisely, I’ve seen a lot of printers have a control board on the hot end to which the heat cartridge and thermistor are connected, with a ribbon cable running from the hot end control board to the main motherboard.
My printer does not have this secondary control board. There is a 1.5m wire running from the thermistor all the way to the main motherboard, same as the heat cartridge. Replacing the unit means replacing the entire connection, from unit to motherboard
Yup. Granted, that was with an IR thermometer, which doesn’t get very good readings on small shiny things. Using a probe thermometer get me around 160c. This explains why I was able to extrude for a short while, at 95c my filament is not even soft, 160c is obviously still far too low to print but it was hot enough to partially liquefy the filament.
This is actually really cool. You should make sure that this comes up when just searching for cat stuff, maybe a cat owner doesn’t know the original product exists and can now make their own instead of buying one.
You are saying this like they are not aware… like telling a drowning person that if they don’t stop breathing water they’re gonna die. The point is that using credit in the first place isn’t always a choice. Just because it is for a lot, maybe even most people, doesn’t mean there aren’t a lot of other people for whom it isn’t.
the replies are divided right across the acab/thin blue line
Unless there’s some weird fediverse thing going on where I can’t see all the replies, there’s currently 4 comments (including yours, not mine), and literally every single one calls him a snitch or a narc. Again barring fediverse shenanigans, you’re straight fabricating a divide along a political barrier in a comment section where none exists for… reasons?

Mine right now off the top of my head is Adam Savage, former co-host of Mythbusters years ago. I sometimes watch his Tested videos whenever he answers questions and he answers them very thoughtfully.

My immediate response was also Adam Savage. I say this while laying in bed, background watching mythbusters as I do every night. I’m studying to become an engineer and it’s literally because of this show and how interested it got me in science and just understanding how things work as a kid.
It’s been a dream of mine for years to meet the man and thank him, but he seems to keep himself quite busy these days. I just watched a 12 minute video of him simply talking about a pencil and I hope he never changes.
Since you’re here now, I got a lot of use out of my Neptune 3, which you can get for like $100 from their site now that the 4 series is out. That being said, you can look at my post history and determine if that’s the printer for you. Though for a hundred bucks it’s a pretty solid grab.
It took a little bit of tinkering to get it where I wanted it to be, but once it got there I had no complaints (until, see post history). I got it when it was new and I feel I got my money’s worth, for $100 it’s great, but if you want something to perform as good as even Elegoo’s newer entry level printers (like the Neptune 4 series), it’s going to take work.
First I’d like to say thanks to everyone for looking at these posts and trying to help, and sorry to anyone who may be annoyed. Trust me, I’m not happy either....
I drilled out the top a little bit more, and used a bolt with the same thread as this small coupling I had laying around to thread the inside a little bit. The coupling’s mouth is only large enough for filament to fee through, not the Bowden tubes. So, the tube inside the heat sink is sandwiched between the nozzle and the end of the coupling.
Unfortunately, clogging is still occurring. During the modification I switched in my all metal heatbreak; the clog is forming at the nozzle. What I believe is happening, is my thermostor is not reading reporting correctly at higher temps, the nozzle isn’t getting hot enough, and only ~95% of filament is actually making it through the nozzle, the rest is getting built up slowly in the heat break until the extruder can’t push anymore. When I first went to hand feed filament through my new setup, I discovered it was incredibly difficult to push filament through right from the get go, before any clog had the chance to form. I ordered a new thermistor and heat cartridge that I’ll try out tonight.
If those don’t solve my problem, I think I’ll have tried replacing everything related to the problem. At that point, I’d think it’s just time to start saving for a new printer and donate the old one to someone smarter than me.
