I'm probably going to buy a 3d printer when tax return season comes 'round. There's a 3d printer I can use at my Hackerspace but babysitting a community printer for 10 hours kind of blows so it seems practical to get my own. I've used Bukito and LulzBot, and I really quite like the Lulzbot, and it fits kinda into my price range, in the low $1000s. What's a decent printer for some sorta rear end in a top hat like me? Or what should I look at to get a better idea of what I want?

Thread the bolt into that side first, and keep going through the unthreaded side until the length you want is in the middle. Snap the bolt off, and as you unscrew it, the threads will get reformed. Enjoy! Holy poo poo i was about to buy some of those auto adjusting strippers but maybe I should just upgrade my normal strippers instead My current pair just has holes for stripping smaller and larger wires than the teeth can handle

They’re running a special on mk3s kits now so shipping is only $50 or so, but as soon as you add anything else to the order shipping shoots up to regular Czech pricing levels And dropping an extra $30 on shipping for a couple spoils of filament is something I don’t think I can swallow

Finally printing the prusa logo after ~4 hours work today, downloading octopi in the meantime... I was working on calibration over lunch. Prusa logo failed pretty hard due to bad adhesion Watched a YouTube video where a dude suggested just cranking the z down until you can’t just slide the filament off the bed with your finger so I worked at that and it was looking good but then I was already over my lunch break and I didn’t want to start a test print and walk away so now I’m real anxious to get home and start printing rocktopus and benchies and Dragon dicks and some printer upgrades I also have no idea how all the cables are supposed to fit so comfortably inside the control box, mine has a pretty good bow to the door because it’s all just shoved in as best as I could Sockser fucked around with this message at 21:14 on Mar 5, 2019 |

Babby’s first benchy Decided to go whole hog and skip the Prusa logo test print Got a decent initial z, went straight for the benchy   The tops of the arches are just a tiny bit hosed and the top of the front window has a wonky corner, but overall a solid 9.5/10

Yesterday I had my Z level dialed in perfect and everything was going great Tonight, it's somehow dropped by a good amount, such that there wasn't enough room between the print bed and the extruder for it to actually like, extrude So the extruder gears were skipping or something and it was making an awful noise Got it sorted, but I've got a suuuuuper thin layer of PLA filament stuck to my build plate that I can't even fingernail off. Should I just let it go and let another print peel it off or is there some sort of magic I can do? E: Something still needs adjusted, this first layer is lookin hosed

An hour of loving around led me to adjusting the Pinda sensor. Now it’s not crashing the nozzle into the bed any more so that’s cool, but I didn’t have enough time to run through a full calibration Also a bunch of PETG showed up in the mail so now I can throw all that awful awful ABS into a closet and forget about it forever

nine16thsdago posted:i haven't had quite the trouble you've shared, but i suspect my PINDA sensor has moved slightly as well. i printed an ESP8266 case this morning and the bottom (1st layer) of the thing is visibly different on one side than the other. i've had a few other quirks as well. perhaps i should tighten it up and re-run the calibration / test patterns (the bottom layer of the prusa logo benchmark works great for this, BTW). I got some orange Amazon Basics to hopefully match the Prusa parts so I can add some bits to it, as well as these guys: https://www.amazon.com/gp/product/B01M6WENG6/ref=ppx_yo_dt_b_asin_title_o01_s01?ie=UTF8&psc=1 https://www.amazon.com/gp/product/B07D76FY15/ref=ppx_yo_dt_b_asin_title_o01_s01?ie=UTF8&psc=1 https://www.amazon.com/gp/product/B01M9AF0JZ/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 I've only printed with the first so far, but it's been pretty great, albeit stringy as hell, but I am just using the default PET settings in slic3r    e: hell yeah

The amazon basics filament is not printing as nicely as my weird Chinese YOYI PETG, it’s getting all boogery on the first layer I guess half the fun of having a 3d printer is having to dial in exact settings for every different roll of filament, but what exactly should I be playing with here? E: And you can see it’s not all of the pieces in a single print that are going weird

Nah, that’s just the way either the light or motion blur is catching things— I decided to let it go even though the print wasn’t going to work, and now I have a shift in the Y axis as well  e: I did have it printing a 140% of Prusa's standard PETG settings and I did have octolapse yanking the extruder off to the corner every 3 minutes But I killed it and I'm gonna restart it and run it slower this time and see what happens Sockser fucked around with this message at 17:03 on Mar 13, 2019 |

3d printers are neat because you slice something up, send it to the printer, come back in 12 hours, and you now you have a thing, just like that Except I find myself continually hypnotized just watching it go back and forth for like 30 minutes at a time

 Playing around with some stuff to try to get my infill visible behind my perimeters, this one worked decently but the pattern is too small. I’ve got another print going now with 3d honeycomb infill cranked down to like 3% but so far it’s looking basically the same, despite the pattern looking kind of huge in slic3r (or maybe I printed the gyroid one instead) Are there like... alternative infills that do more of a vertical tiling than a horizontal tiling? I could theoretically run this print on its side instead of its base but then I need to gently caress with a ton of supports, but just being able to get some funky patterns showing through these should be neat, I think?

ReelBigLizard posted:Did you check your stepper driver current limits? If they're too low then you might just be skipping steps because the motors aren't strong enough. Cleaned and Oiled your linear bearings too? The only one of these that hasn't had layer shifts is the one where I decided to be patient and only cranked my printer up to like ~115% of the Prusa settings So after tensioning, I tried running one at 175 and that one failed real quick I've got another going at 110% right now and I'm just going to let it go I've dialed down the infill and other settings enough that I've gotten my first 16 hour print down to 12 so I'll accept that wait

Frozen Pizza Party posted:Are you using the speed or quality preset in slic3r? The speed one has 200mm/s movements already, so cranking that up higher than 100% is iffy, imo I was on quality, as it had never really occured to me to hit that dropdown and look at the other settings there. This is neat!

Did my first print of a thing I modeled myself and it feels so good! It's a miniature version of my arcade game, Scoot Pooch Spent 4 hours slowly turning my woodworking Sketchup model into a solid, which fuckin sucked  And it turned out pretty great!  But gluing the three pieces together kind of sucks (you can see some CA glue dripping out under the first O there) and if I want to distribute these to people it'd be rad if the pieces could instead snap together or at least have some guide pegs. This also provides a good opportunity for me to learn a real CAD program and stop using Sketchup. Are there any decent guides on how to model out pegs and snaps and stuff or even, by the grace of heaven, an app that'll do it for me?

TKIY posted:Didn't cross thread, the nut just tore up the plastic as it was being pulled in and then rounded it out. I can drill out the screw I guess. If the nut rounded out the hole, you should be able to get pliers or a knife in there to hold it If you didn’t get the screw all the way in, you should be able to push the nut out with the screw The only part of the Prusa assembly I had trouble with, outside of putting a few things on backwards, was getting the plastic bits to snap on to the end of the x rails. Did a good bit of shattering to the one, but not enough to compromise it structurally. That when I switched from a mallet to a clamp to get it all the way on. The nuts were rarely ever a problem and I have no idea how you did the thing you did

So here's this loop I seem to be on Like four days in a row of great prints -> one print goes to poo poo real hard, usually a bubbled up blob of PETG somewhere -> print crash yay -> now my z alignment is hosed up and the nozzle is digging into the bed -> yank all the baked on PETG off the nozzle -> try to adjust my Z height -> can't even get a calibration print going because all the filament is just sucking back up around the outside of the nozzle instead of the print bed -> get angry and go to bed -> the next day, heat it up (again), clean all the baked on PETG off the nozzle (again), give the nozzle a good alcohol/acetone wipedown (necessary? I dunno) -> now it works fine And I'm not sure why the hell this keeps happening or why I find myself once again stuck in this "CANT GET ANYTHING TO PRINT" loop. I've only had this printer for two weeks and this is, I think, the third time I've found myself in this situation. Is there something dumb that I'm doing or does PETG just naturally cause problems like this? And if so, how come it's fine for fuckin' days and I've got my settings dialed in and then it goes to poo poo and then I need to recalibrate everything?

Frozen Pizza Party posted:Not sure why, but it sounds like it's clogging the nozzle. Use the accupuncture needle it came with to clear the jam if it's doing the sucking up around the outside thing. I've only printed one thing in PETG on the prusa thus far, but switching from that to PLA was no issue. Haven't had any issues with any of my PLA prints either. I can manually extrude just fine, and the purge strip comes out normal, it's just once it gets to printing it wants to mushroom up

That’s fuckin wild Octoprints great and I’m sure I’ll appreciate it even more when I get a second printer

3 hours into a 5 hour print of several parts at once 4 of the parts are looking good, one has turned to spaghetti. I can’t really get home to restart the print, so the question is if I let it go and hope it works out or cancel the entire print so it doesn’t get worse Update: the spaghetti got stuck to the extruder and that was that.
