ZincBoy posted:I have the Vivedino Troodon and it has been running fine for the last year or so. The only thing I don’t like about it is that it does not have a direct drive extruder and the Bowden tube is ridiculously long. Pla works fine but is suspect that PETG would be a challenge to avoid blobs and stringing everywhere. That encouraging to hear. From what I’ve been reading, the current Troodons are now shipping with a cloned BMG direct drive extruder.

https://www.3dprintersbay.com/vivedino/vivedino-troodon This says it's using an Orbiter v1.5, which is an excellent extruder. It has a few issues with the interior filament guide getting worn down, but it's a cheap and easy replacement and should be fixed in v2. (I have the v1, which has a metal guide). Get the Dragon hotend (or better).

Ugh, I replaced the hotend on my prusa mk3, redid first layer calibration to look beautiful, and have a spotless and freshly washed build plate, and the front corners of my calibration cat are lifting. I'm starting to think this is a roll of dodgy PLA, despite being jessie transitional. Any thoughts?   he's being printed at default size, at 215/60 degrees. i'm trying with a roll of black hatchbox right now to see if it fares any better.

ImplicitAssembler posted:Did you redo your hotend PIDs? (That is a thing on Prusa's, right?) I did, recalibrated at 215. It also has a Temperature Calibration feature for the pinda sensor, but the one time i calibrated it and turned it on, i made air spaghetti, so i don't use it. The hatchbox test has only printed his little feet so far, but they appear to be sticking. I may have just gotten a dodgy roll of jessie transitional. More on this as it develops.

The last two transition rolls I've tried to use were kind of terrible. One had wildly inconsistent diameter, to the point where the extruder motor was skipping intermittently as it tried to push through the fatter spots, and the other one was so damp right out of the box that I just shitcanned it. I've got like eight more of them laying around here too, and I'm kind of hesitant to use any of them now.

It's also harder to see potential warping on black filament, so i'll have to wait for him to finish to really compare the two. Edit: hmm, he doesn't seem to be any better. I think I'm gonna send this printer through a full refresh to eliminate any possible gremlins from firmware, calibrations, etc. https://help.prusa3d.com/en/article/full-system-refresh-original-prusa-i3_133258 i dont have a photo, but the angle of warp is about the same from the jessie to the hatchbox, so i think something about my settings might be off.

ImplicitAssembler posted:https://www.3dprintersbay.com/vivedino/vivedino-troodon Thanks for mentioning this! I have ordered the upgrade kit so I can fix my main issue with the printer. The only other issue that I have had is with the filament run out sensor. The spring for the switch is strong enough that filament tends to break in the sensor itself. This only happens with filament that has absorbed some moisture. Still for the one time I actually ran out of filament, I think it has tripped 20 times due to the filament breaking in the sensor.

There’s something really awesome about saying to yourself, “oh dang, I need another one of these weird custom pieces I made a couple years back” and then you just hop on your printer‘s web interface, go to that project’s folder, find the thing, and come back an hour later to retrieve another of the weird custom piece you made a couple years back.

Perhaps, although it was exceptionally nice to not even bother firing up the slicer and going through those few extra steps. Just find the object in your library, print, and go gently caress off for a few minutes. Amazing.

I use Blender to make things, but that's for sculptures and not anything that requires exacting dimensions. I just remesh everything to make sure it's manifold and export it as an STL and worry about sizing it inside of the slicer.

I am new to modelling in the last three weeks, and Autodesk 360's free personal license is working well enough for me with the help of a few YouTube videos. I'm a software engineer, and it's close though to concepts I can wrap my head around, but has some serious limitations to me, like burying the math/parameters. I've played around with a few other free things, but I wanted something relatively powerful even if it has a somewhat weird niche or learning curve. I get the feeling like 360 doesn't know what it's good at. I've only made a couple enclosures / ePaper frames, so by no means am an expert.

I literally just noticed the "enable autosleep" toggle in Duet3D. Looked into what it does, just runs sleep.g after a print finishes. Oh, sweet, I would love it if I could set my printer to shut down everything down after finishing in some cases, let's see what's in there now:quote:Oh. Nothing. Okay, a quick look at the gcode reference and I run into M81: ATX Power Off, which as of RRF 1.20, accepts S1 = "turn power off when all thermostatic fans have turned off". Sweet! I think that's exactly what I want! Let the extruder cool down until its thermostatic fan shuts off on its own, and at that point, turn off the ATX power supply and go into sleep mode. But of course I'm nervous about issuing any sort of power off command with a hot extruder. Can someone sanity check this? sleep.g: code:code:Bad Munki fucked around with this message at 06:34 on Jul 27, 2021 |

Maybe I'm just getting too old for this poo poo. Babies are exhausting There are a lot of things that don't work like I want them to but for some things Blender is really awesome and you don't need to know a lot. However, you need to know specific things and I can't imagine learning those pieces from youtube videos. What's really easy is making parts from a model change in size or disappear. Some examples, I made this fridge handle from scratch using basic shapes and curves:  I often take parts from different models and weld them together, like this v-slot insert with a mounting part.  I edited the scale, made a recess into the stump so the owl doesn't fall off easily and made holes so the lightbulb and stuff could fit in:  I am not very good, but good enough to help with some basic questions. If someone has a concrete example of what they want to do I'm up for trying it out and then explain via streaming or whatever. Or give a basic overview about the functions I use all the time. And if I can't help, at least it won't take over 18 minutes to realize that. PM is also ok.

Yeah mainly I just want to generate an STL, for example, a 2x2" square plate about 3mm thick, with a smaller 1/2" hollow square that's about 1" tall, in the middle of the plate, wall thickness also about 3mm, so I can glue that to the deck of the boat and stick the vertical mast in it, aka "mast step". Not much different from a patio umbrella stand. The blender guy makes it sound like you have to modify a billion settings so that the STL file comes out the correct dimensions

I use OpenSCAD but I'm a software developer with a background in functional programming, and that's a pretty narrow demographic.

I have a coffee grinder handle with a 3d printed prototype. Haven't had time to design the improved version with bearings and the first prototype was wearing out so I could just... print another. Those files still exist. Not ideal but if another 6 months pass before I finish the design, I'll just spend another < $0.25 to print again

There's a pretty big difference between 3D programs designed for CAD work and 3D programs designed for digital sculpting. Based on your mini comment I would imagine you're leaning more into the digital sculpting direction and as such would highly recommend blender. It's free, but there's a significant learning curve to it (which is going to be there for any digital sculpting program).

I'll check it out. Like I said, the original idea is very... basic in what I need (we're talking adaptingsomething made back in the 80's/90's at a 30mm size, so it's fairly light on fine details, to something that's about 6" tall), so I'm hoping that it'll be a good starting point for learning the program.

OpenSCAD is something for simple procedural things. If you need to start addressing specific edges or vertices, be it for simple fillets or defining feature aligned planes, you're in a world of hurt. That is, if it's even possible to address specific part features in OpenSCAD. (Is it? I don't know.) Do poo poo like this in OpenSCAD:

OpenSCAD has a teeny tiny "genuinely the right tool for the job" niche that will not come up for most people, and its CAD functionality is extremely primitive. Also it's a nightmare to use if you're not a programmer first and foremost. Sketchup has absolutely nothing going for it in 2021 for this purpose. Blender doesn't sound like a good fit for your needs either, although it ought to be capable of what you want. Just grab Fusion360, imo, it can do what you want in a straightforward way but is much more powerful if you want to start making better designs (once you fillet up a blocky model for the first time you'll see the appeal of a more robust CAD platform, even if you're mostly working with primitives.

Pro-tip for Klipper users, that use a NTC100K beta 3950 thermistor. Apparently the beta calculation generates values, while mathematically correct, that are bad in the regions where you might run your hotend at. Over here I've apparently been printing at 260°C while 245°C was displayed.  This is a correct(er) thermistor definition: code:
