Is there a competitor to the XL with regard to multi-toolhead? Like 3+ tools. Not a fan of the purge heavy style like Bambu.

At the very least it seems like Bambu now has solid competition at the 800 dollar price point of the P1P. I will be very curious to see if the MMU3 doesn’t suck

Well the neptune 3 pro arrived and after a quick and painless setup started printing beautifully. Still figuring everything out but its a blast already. My wife has already hogged the print queue due to an abundance of cool things she already found. Super fun so far.

Is anyone here running windows 11 and able to connect to an Ender 3 via USB? I've tried quite a few things to no avail, and while I can go dig out an old machine and set it up, I would prefer to get this working on my laptop. Windows doesn't appear to detect it at all. I've grabbed the various driver bundles folks suggest, manually added a legacy device for it through Device manager, tried several different USB cables, basically all the things I can find suggested online.

Not sure if you’ve already tried it but either plug it into a USB2 port or run it through a USB2 hub - sometimes older USB devices don’t work right on USB3 ports.

Also it's nice to hear that the MK4 (and its components) have been churning away for ages by now in the Prusa print farm; that gives me a lot of added confidence in them being solid with kinks worked out.

Yeah so I just cleared the BLtouch data, meticulously leveled my bed the old fashioned way with a piece of paper, and then had it print some nonsense while I manually tweaked the z-offset. Easy and works well now. I have a glass bed. It ain’t gonna be substantially out of flatness. Screw this automatic crap. At least this variant.

I just installed my replacement Revo heater core yesterday. So if I get the MK4 upgrade kit I'm stuck with a practically unused Revo, 3 nozzles, original used v6, and half an MK3S in a box? Getting an entire MK4 seems like the only logical decision. Conversion rate, shipping and taxes to Canada is...ugh Have to wait for local availability.

I don't have my free ender 3 pro yet to frankenstein, but in the interim I'm trying to debug an issue that I have with my existing ender 3 pro that comes up every now and then. If I print something that has a thin, exposed base, I get the sharp "too close to the bed" corduroy effect on the top surface of it. The first layer goes down smoothly, but with the layers after that it gets more and more pronounced. Anything with infill doesn't have the problem, presumably because the excess filament has somewhere to go, but solid flat bottom sections will generally have it. My first thought was that I must be overextruding slightly, so I checked e-steps and I extruded 99.3 mm of filament with the command to extrude 100, so that's not it. I checked the filament thickness, and it's correct. I printed a calibration cube from here https://3dprintbeginner.com/flow-rate-calibration/ and the single layer base is nice and flat, and the walls measured .81mm, so pretty damned close to perfect. The overall cube size is also pretty damned close to 30mm. I turned off combing and it didn't resolve it. Anyone have any suggestions for other things I can try? Edit: Here's a photo of it, this is at the top of the 4th base layer of a print. I scratched some of it back, but the part of the right is unmolested.

Presumably by the end of the week someone will have an adapter for the ender 3 series and I can order a nextruder for my ender 3 v2, once the nextruder stuff get spliced in to marlin/j3ryl or whatever Presumably the weakest link on my e3v2 at that point will be the power supply trying to keep up with the nextruder's volumetric (melting?) capacity Still sitting on my 5 tool preorder, but not sure how much time I have for designing melt-away supports etc with a toddler crawling all over me now, and not sounding like laser engraving is going to be a feature coming out in the first year

So my Neptune 3 pro is working well so far, only small complaint I have is the noise level of the print head fans. They sit at roughly 50db on average, which I realise is not that bad, but definitly distracting since we have it in our office/living room where we spend most of our time. Easiest obvious solution I found would be an enclosure. Do the fabric enclosures by for example creality make any difference, or do I need to build something more fancy? Any other solutions I'm overlooking?

I don't think you're going to tell any difference in noise level with a fabric enclosure, although you might be able to measure it with a decibel meter

I've watched videos of people replacing ender fans with winnsinn fans from amazon for significant noise reduction.

Helped my school set up their new 3D printers, they bought some nice Flashforge ones with dual heads. My background is a temperamental Ender 3 I bought semi-broken so it was pretty impressive to see how easy they were to set up, how quickly the hotends heat up, etc. What ways are there to optimise when running two heads? I don't think they will be doing many two colour prints, so I was thinking one with a larger nozzle and one with a smaller one; I'm guessing slicers can optimise this so it can use the bigger nozzle to spit out big, uncomplicated stuff and use the other one for detail. They do have two printers though, so could set one up for smaller detailed pieces and one up for bigger, structural ones. Or is there something else I should be thinking about? I have no idea what they're going to be using them for, I don't think the department quite does either, lol.

Most of what you mentioned is irrelevant. If you are too close to the bed, you are too close to the bed In no particular order: Z height First layer height First layer extrusion Overall extrusion ratio With all of the above, if you are only obsessed with getting the first layer to stick, you end up lowering z, but you still might be pushing too much stuff out for the layer to handle. You tuned your extrusion steps, but I had to turn my overall extrusion ratio down to .84 from 1 and all my issues went away. Follow the ellis tuning guide. You can largely ignore anything around speed on a non voron, but you definitely need to print some squares and test your z, then do some extrusion cubes. Speeds you can add to later, but absolutely make sure your volumetric limit is set so you can never outrun your hotend

Here's what Prusa offered me after I asked about buying a MK3S+ that was still in transit when the 4S was announced:quote:Hello, Yeaaaaah, I know legally they could just offer absolutely nothing. But the 4S upgrade kit is $579 and won't be available until June. Plus I'd have to assemble it after paying for a pre-assembled printer. I'm just going to return all this poo poo when it gets here later today. I was excited, but now I might wait a few more years before I get into 3D printing.

Buying a printer these days is a lot like buying a computer has always been. There's always something newer and better right around the corner, and waiting to do a "future proof" purchase is just going to leave you waiting forever. The timing with the Prusa thing is kind of lovely right now, no argument there, but you can also turn around and buy any number of sub-$300 Chinese printers these days and be cranking perfectly good stuff out in no more than transit time + 30 minutes of assembly. Or keep the Prusa and do the same thing with better quality and higher reliability. eta - the Mk3 isn't even obsoleted, it's just been superseded by a new model. It's like being angry about more modern versions of your 2017 Camry existing. Acid Reflux fucked around with this message at 17:23 on Mar 30, 2023 |

One big advantage of that MK3S is that you can upgrade it at your own pace, and there'll be an upgrade path from it beyond the MK4 to whatever revisions of the 4 they release later (and possibly even to the 5 and whatever comes after). I'd stick with the MK3S to learn on, get the MK3.5 upgrade in June for $50 to get the majority of the nice upgrades like the better screen and the print speed upgrades, then decide from there whether it'd be worth it to you for the fancier extruder and motors.

Roundboy posted:Most of what you mentioned is irrelevant. If you are too close to the bed, you are too close to the bed I'll go through that guide, but the thing about being too close to the bed is that I'm not really too close to the bed. The first layer is pristine, and if I back off much from where it is I get separation between lines. Also my calibration cube dimensions and wall widths are spot on. I may need to dial back my overall extrusion ratio ("flow" percentage in cura, assuming we're talking about the same thing?) and I was already planning to run some tests with it at 95, 90, etc. The thing that has me scratching my head is that I only get this issue with multi-layer solid base areas. Edit: Here is an example cube. The walls and overall dimensions measure true within .01 or .02 mm with digital calipers, and the single bottom layer in there is smooth and has no gaps. The small blips on the corners are from the randomized z-seam location

Everything new on the MK4 is an incremental improvement on the MK3S, there isn't anything radically different about the underlying technology and there isn't anything you will be able to print with a MK4+MMU3 that you couldn't already make with a MK3S+MMU2

The hot-swappable hotend on the extruder seems like a nice feature, but seems like a lot of the electronic upgrades are equivalent to running an octoprint, which I already do. I think I'll stick with my 3S+ for now, and worry about upgrades if my current extruder ever has a catastrophic failure.

If it was me I would definitely return it and get the MK4. It's way more than just a tiny upgrade. As someone who lost a hotend to a blob of death. The Nextruder with the longer heartbreak would prevent that. Quick swap nozzles, that most likely cost a lot less than the patented Revo system I bought for my MK3. Auto bed focusing. Not having to do the Live Adjust Z ever again! One less thing to worry about and waste time on when you change nozzles or switch sheets. The upgraded electronics means not having to source a Raspberry Pi and install Octoprint to avoid using an SD card. The screen on the MK3 is archaic. Upgrade kits don't come with the new dampening frame, thicker z rods, and you have to print your own parts.
