I guess the big thing for the XL is it's a complete green sheet design, just about everything is custom made and designed with few off the shelf parts. Most of the technology got released to the prusa Mk4 though? Curious to see what the aftermarket does with the tool charger

The XL does a few unique things. The bed is unique, and I suspect it will bear out to be good. Prusa has evidently figured out the head exchange system. And a method for defining the nozzle in 3d space, which isn't a thing in most other printers. Though not unique to the XL. The strain gauges in the head are a big deal, and I expect that will become industry standard. Now that prusa has figured it out, as usual, other companies are gonna do it. It comes with a large diameter drive wheel extruder, which is a thing that will be the standard coming soon. The planetary gearset also avoids the problems relating to setscrew pinned drive pinions.

I believe the position of their strain guage can also measure hot end pressure. My impression is that this isn't happening yet, but was mentioned as a possible thing. Similar to when prusa said the first filament sensor on the mk3 could detect jams. Technically true, but it was never implemented due to complexity that they didn't account for before they actually looked into it. I think the XL we have today is a shadow of the machine it will be in a year, but I also think prusa has a habit of over promising certain things.

I mean, in a year printers will have advanced across the board, poo poo keeps coming out like every day. I feel like where printers were a year ago is a shadow of where they are now, there's just so much going on in the space. I think once good reliable hobbyist printers that didn't need you to spend hours getting your printer to print well the market really saw an uptick in users, which drives more innovation because there's more money in it, and there is a lot of different gradients of users.

I predict the X2C will be amazing, yes. I also predict the X1C will not be upgraded to keep up with this progression. That's the difference vs the XL that I'm really expecting.

An interesting thing there is that the Bambu A1 has rolled out a jam/tangle detector, so I think they beat Prusa to the punch there if they haven't implemented it in the XL yet. It has a nozzle pressure sensor it uses to do the 'Active Flow Rate Compensation' stuff, and also detects and pauses on jams or filament tangles. The A1 seems like a testbed for some of the new stuff that presumably a X2/P2 might roll out with in the future. A: The jam detection + Flow/pressure sensor. B: Tool-less, swappable nozzles, without thermal grease. (God, I'd love a X1 toolhead upgrade with that in.) C: The A1 prototype did have some induction probe in the head that didn't make it to the production version. I guess one thing that'll gain/burn a lot of goodwill with Bambu is how the transition to newer printers will be. (X1 -> X2 upgrade kits, for example?) StrixNebulosa posted:But, kind of related… what’s a good way to clean a nozzle? My stringiness is getting a little silly. Cold pull, heat + scrape, or just getting a new nozzle? You're on an ender right? Swapping for a new nozzle is quick n easy, and you'll avoid any wear the old one had. Nozzles are basically consumables.

Sweet, good to know! And from a quick glance you can get like ten of them for 10$ on amazon, so perfect that's within my budget. (My budget is consumed by pins and filament)

My prints keep jamming. Like, the filament isn't coming out. I have so far: * Replaced the nozzle * Replaced the bowden tube * Cleaned the extruder * Adjusted extruder tension * Made sure the fans are okay * Replaced the filament multiple times Every time I try to fix it, it starts out extruding just fine, and then just stops. All I can think of to try next is replacing the hotend and twiddling the extruder tension again. Or I could flip the table and order this $30 El cheapo "direct drive" unit that's actually got like 2cm of Bowden tube. Or I could buy that MK4 I've been coveting for a while now. But then I'd still probably want to fix this Ender 3 V2 so I could in good conscience give it to somebody. Before I drop any money on anything, I figured I should collect opinions from the pig balls forum. Thanks in advance

Have you tried a different roll of filament? To expand on this, I had a roll of hatchbox petg which was so far out of dimensional tolerance that it would cause the weirdest problems any time I tried to print with it.

Just wanted to say thanks for the help, thread. There was still some odd z-layer shifts going, especially a really bad one where the roof joins but nothing I can't fix and hide when painting. I ended up having to print at 100mm/s way below the 250 default, and turn the cooling fans completely off. Which is annoying because speed and high power cooling is one of the big selling points of this printer. Went from what should of been an 10hr print to a 22hr one. But as I've learned with resin printing I would rather have a slow, successful print than a fast failed one. Edit: I should also note I had Z Lift turned off, wonder if this could of saved me a lot of headache. Springfield Fatts fucked around with this message at 16:27 on Sep 23, 2023 |

Hadlock posted:I occasionally get these ads on social media to "make your own pin" or whatever and so I looked through your post history to see if I could figure out why Also to answer your question: the sadly defunct enamel pin thread. I've moved since I posted it and have all kinds of new/different pins. A quick tl;dr: enamel pins are fantastic little pieces of artwork that you can hang around the home, put on your clothes, or convert into magnets for your fridge! There's an entire economy about buying and selling and making them, as the machines necessary to make them are all stuck in China, and you have to make pins in batches. Most Americans will see the (kind of terrible) pins you see in malls and such - using this example entirely randomly: https://www.walmart.com/ip/Dragon-Ball-Super-Ultra-Instinct-Sign-Goku-Enamel-Pin/499562802  Soft enamel pins like this are cheaper, but imho look kind of terrible if you're not careful with design. I in general prefer hard enamel pins like this: https://alchemyartgroup.com/products/025-bubble-tea-pin (I have bought from them before and really like their pins)  Most are 1-2 inches, and can be of literally anything. I love to collect these, and thus we come to the problem of displaying them - I hate the look of corkboard, rigging frame+canvas/cloth is annoying, and while I've had success with felt hexagons purchased from amazon, they're a little annoying to hang, and there's no variance in size/shape without $$$. So, well, 3D printing to the rescue! I'm printing another board as we speak, and if I've done the CAD correctly I'll be able to use a string to hang it on a nail with the little legs. ("why don't you wear your pins" because I collect the limited edition pins - some of my pins are actually worth $$$ and/or aren't replaceable. And some are 4-5 inches and you just can't put that on a hat!)

Buying enamel pins on AliExpress is a dangerous game, soon you'll have a pile of 50 pins and question what the hell you're doing There's also a lot of bootlegs and such on AE so you should maybe consider, if you find a cool pin there, giving etsy or somewhere a quick search and see if you can support the original artist instead

This is exactly how I feel right now, my Sovols were a big step up from the Taz 5 I used for years, but 1 day with the Bambu and if it keeps up like this for the long term I don't see why I'd turn the others on again, it's seems faster than all of them put together.

Also toolchangers in general are the only really good way of using multiple materials. Single-nozzle multi-spool systems can work decently for multiple colors of the same stuff (as the AMS demonstrates), but if you're going to be using stuff with significantly different properties in the same print -- say a model material, a flexible material, and a soluble support -- you really need to dedicate a separate extruder to each one. Toolchangers also let you use both a large and small nozzle in the same print, which is theoretically compelling, though I haven't seen a specific really good example of it yet.

I build anatomical models, and I always have to inflate the size of small structures like some nerves/arteries to a cartoonish scale. I'd love to be able to print a skull at 1.5-2X life scale with a 1.2 mm nozzle and build the nerves on it with a .2 or .4 nozzle so the relative scales are closer.

Seems like if you were designing some stuff in CAD and had a bunch of big flat surfaces connecting together the more intricate mounting points/holes you could get away with a 1.2mm nozzle (or wherever the hot end maxes out volumetrically) for 90% of the print and then the 6% of the print that needs the finer detail, roll back to 0.4 or 0.1mm A lot of what I print is roughly conical in shape, much larger at the bottom and then tapers to a point pretty quick. Would be great to knock out the first 10 layers which almost never have any interesting detail with a 1.0 nozzle, then dial back to 0.4 or 0.6 Printing supports in PLA and the model in PETG (or whatever the magic combo is) seems pretty magical, they just snap apart cleanly with zero mess. At a minimum the 2 tool model seems like a huge win just for that

Had my first spaghetti ball of death overnight. It had printed a good 1-2mm worth of the print before it failed! Well beyond a good first layer. And it was on my K1, so some of it got sucked into the chamber fan. Hope it still works and that it didn't bind up and burn out the motor too.

This is the big reason I’m still keeping an eye on the Prusa XL instead of just picking up a Bambu. I’d love to have a really good multi-material option, especially with the recent stuff in Cura that lets you mechanically interface incompatible materials. Bambu is killer for aesthetic prints, but kind of meh for functional ones. They’re fast but so is my SV06 after I klipperized it; the AMU is their killer app and it’s “only” really good for multicolor printing.

It's also good for having a secondary support material like petg for a few layers on a pla print. It's also nice to load a big print and put 2 different rolls of the same stuff in it. Multicolor is in my future but even just doing single color prints I'm glad I bought the AMS option.
