It definitely still looks like under-extrusion, which is why you're getting advice like the above check that your printer is configured for the correct diameter filament.

What filament settings are you using on your slicer? Maybe your slicer has a low EM.

I'm currently on this step: https://ellis3dp.com/Print-Tuning-Guide/articles/first_layer_squish.html It doesn't hurt to double check it. If you do double check it, I would do so with the filament just going through the extruder and not the hotend if your printer allows for that. (ie: disconnect the bowden tube if there is one)

Is that a Woods chair? Because I got to hang out with a Canadian acquaintance that had a couple and those are by far the most comfortable camp chair in human history. You sink into that thing and never want to leave. I've been wanting to get a pair but am a cheap bastard and refuse to buy more until my existing chairs wear out. If it is, congrats, you Canadians really know how to make thrones.

BadMedic posted:Edit 3: poo poo like this makes me want to install linear rails for the bed, but I have no clue how I would do it and it would also cost more than it's probably worth Don't. Linear rails have a shorter lifetime, and can't be repaired. They are also more vulnerable to "poo poo" intrusion. Get your v-wheels setup right, worst case is you need to tighten the pinch bolt so they don't loosen. deimos posted:Uhh, why "whut?" this is exactly how this works. Extrusion length calibration is setting the extruder to extrude (as close as possible) exactly the amount you're expecting it to, it's an extruder setting calibration. Extrusion multiplier is about the variations between filaments and it's done properly by printing tickets. To clarify this. The extruder will mostly extrude the length it's told to extrude. Mostly. So this needs to be set, so your other data is useful. Each filament will be some variety of different diameter, different stiffness, different compressive strength, and all of those will add up to a specific filament extruding more, or less plastic through the nozzle. Extrusion Multiplier is how you compensate for "per filament" differences. If all your printers are setup with extruders that extrude the same distance, all the EM numbers will transfer between printers. EM needs to be set ~per filament~. Otherwise, you'll have to have EM setup for each printer AND each filament. And that's just silly.

I did the tower test from the guide. It looks like it's almost woven: It's so thin, I can see through it:  As you can clearly see, it's useless for test results. I pulled up examples of other people's print failures and I want to say it's under extruding? Is that right? How do I fix this? With the Extrusion Multiplier? Will I have to do this for each .stl file or is there a default setting for that somewhere to fix every print?

Cura absolutely has that setting. What it is called, and or where it is located may change between versions. Searching for "diameter" might get you somewhere, but however you find it, that would be the best setting for you to check on before trying anything else

it's also what happens when you switch from cubic mm to linear. This is really common on the ender forums.

Also did you say Cura 2? Pretty sure Cura 5.6.0 is the latest, may as well start with an up-to-date slicer if you're starting fresh.

The intermittent extrusion is suggestive of a hardware issue. I would inspect all the parts along the filament path, maybe it's the hot end but it could be the extruder or something as simple as the spool not spinning freely.

Thoroughly inspect the extruder and make sure it's not cracked anywhere. I have seen a few cases where a cracked extruder leads to inconsistent tension on the feed and results in under-extrusion. (This was a big issue with the plastic tension arm on Ender 3s. Not sure about the k1)

I am assuming it is not the same stupid issue with the plastic extruder arm because it sounds like a new printer here in 2024, but that is exactly what that red benchy looks like a symptom of, huh

Pretty much. For example you can't see the thing we're referring to without taking the extruder apart:

His printer has a planetary direct drive, very different setup. e: I think I misinterpreted your post as a direct comparison between the types, sorry Javid! kid, might be worth looking up how to adjust the filament tension on your specific extruder. I know how to do it on an SV06, but I think yours is slightly different. You may have to take the cover off the hot end assembly to get to it.

That's exactly the one. It's an exposed thumbscrew on the 06's and easy to get to, apparently slightly harder to access on yours. It's got to be tighter than "loose", but there's no real world value to go by. On my 06, I generally run it in until I start to feel some resistance and then back it off a turn or two. It doesn't need to be cranked down like stupid hard, but also needs to be providing adequate tension on the gears to grab the filament.

I think I finally understand the root cause of why my bed levelling keeps loving up every few months, and the answer is that my Neptune 3 uses a Strain Gauge for it's bed levelling. On first glance it seems like a pretty simple and clever way to level your bed. It detects if there's force on the nozzle from touching something, so there's no worries of the probe being offset from the nozzle since the probe is the nozzle, and strain gauges are pretty cheap. The problem is that a strain gauge requires non-trivial force, so the nozzle must actually *push* into the bed. If the rollers on your bed are loose, then the bed will shift when pressed, and the z-height will read lower than the *actual* amount. So the rollers need to be tighter, which means they wear from friction faster. And the more they wear, the more rubber is in contact, which makes them wear faster. And I use the printer sporadically as projects need it, so when still for a long period the rollers develop flat spots, which makes them wear faster. So eventually I get a permanently 'wobbly' bed and I'm stuck with either terrible first layers, or replacing all 4 rollers every few months which is kinda a pain in the rear end.
