Here's a video by Maker's Muse briefly covering TinkerCAD, Blender, and Fusion360. https://www.youtube.com/watch?v=Cuqao90C76U I would probably go with Fusion360 due to said popularity.

biracial bear for uncut posted:Isn't the Rep2 what Flashforge cloned with decent success? Also what led MakerBot at the time to go  and decide to embrace closed source because "why hand our undercutting competitors the blueprints to our work?"You might think that's an odd decision for an open source based company but I guess the open sores was only skin deep. Still, in a way they caught disproportionate flak at the time since the only thing they were "closing" was the fabrication level CAD stuff for the enclosure of their new printer, meaning copycats would have to at least do some token reverse engineering and fab work. But it was a lot of goodwill to burn just to put a minor roadblock in the way of copycats and they totally alienated everyone except dumb bosses as a result.

I've been using Autodesk Inventor via an education license, and the program is beyond capable, but it feels a bit like a monkey wielding a cold fusion device. Immeasurably powerful, but all I can manage to do is swing it like a hammer.

Grabbed a Pi 3B+, a Webcam and a SmartPlug to setup Octoprint. Any other must-have plug-ins people are using? I was hoping to find some way to use a smoke detector to trigger a power cutoff, but I'm not seeing anyone having done that yet.

suck my woke dick posted:Speaking of Makerbots: Echoing the replicator 2 being a good printer. My local hackerspace still uses a 2X as a workhorse, same printer with a second extruder. The only issue is that it takes x3g files, instead of gcode. There are ways of getting slic3r or cura working, but MakerBot desktop works fine. I think simplify 3d also generates it, but I'm not sure.

Not sure if I should post here or dig up the old hobby CNC thread (or one of the PC threads), but I'll try here first. What kind of system should I have for designing models? I was planning on using my desktop/gaming system for some and a salvaged laptop for others and as a workshop system. The laptop is a Dell e6510 i7, 10gb RAM and needing a hdd/ssd. Is 250gb enough or should I get a 500gb ssd? I've been using 250gb local and 4tb SAN for so long I don't really realize how much local storage I should have. Is 10gb enough or should I upgrade to 16gb? Shapeoko XXL for CNC router and probably a Prusa down the road. And should router projects go here or somewhere else?

3D models are not very big unless you're doing hugely complicated assemblies or ultra detailed art models or something like that. 250GB SSD is fine. The biggest CAD program I have is SolidWorks, which is about 15GB for a full install. More RAM is always better. 10GB is fine, 16GB is better. You'll want a dedicated graphics card (nVidia is more reliable than AMD in CAD stuff, in my experience) or at least one of the recent Intel chipsets. I have a beefy nVidia card in my desktop and an Intel UHD 620 in my laptop, and the laptop is very usable but noticeably not as fast as the desktop when I have lots of SolidWorks parts with transparency or whatever. Something like an Intel HD 3000 is not going to cut it. Sagebrush fucked around with this message at 02:59 on Mar 1, 2019 |

This guy used the stepper from a dvd drive, but he went super small and only used one for vertical travel with resin. He controlled it with a feather board from adafruit. It's probably too little for what you're planning but I thought the concept was neat even if the execution was a little rough: https://www.youtube.com/watch?v=VCcJjI2u4AU

On the subject of tinyboi pronters, at the size of 50x50x50 Could your part cooling just be a large PC fan pointed at the print bed at that point

I printed an ABS piece for the first time, and I'm left with two questions. 1. Why would my raft only cover ~60% of the diameter of the tile? All of my other brims and rafts on PLA wrap around the entire hex tile. (I'm using Cura for all of this.) 2. The top of the raft is fairly rough. Is the printing temp too low? I ran at 240 nozzle and 110 bed, I believe.

The Wonder Weapon posted:I printed an ABS piece for the first time, and I'm left with two questions. The raft being small looks like some kind of slicer problem. I'd turn on layer view in cura and go all the way down to see if what you see is what you got and check the settings you're slicing with. I use Cura most of the time and while I don't use rafts much, brims haven't ever been an issue when I've used them. I usually make them 2-4mm depending on what I need them for. The top of the raft being rough is sort of normal, they're made to only lightly connect to the part on top so you can pull them off easily. If it's weirdly rough and inconsistent, then it could be overextrusion, worn nozzle, etc. edit: also those temps seem okay, you could try going a little hotter on the nozzle if extrusion seems like an issue, since there's always some variation in the plastic.

TKIY posted:Rex is the bane of my printer. Finally got a first few layers to adhere and the tail split right at the end... Your first-layer squish is way off in that corner. The nozzle needs to be at exactly the right height above the bed to squish the trace out juuuuust enough to adhere. Too close, and the trace will be thin and lumpy and the nozzle will jam; too far away, and the plastic just drops to the bed like a limp rope and doesn't adhere. I've highlighted the ideal appearance in your picture. Adjust your bed leveling and zeroing until the entire perimeter of the part's brim looks like that. It can help to make a part that's just a big box almost the size of your print bed, slice it with the brim turned on, and print and watch the first few loops -- you'll quickly see where the bed needs to be adjusted.  e: by "high" I mean the nozzle is too high, i.e. the bed in those areas is too low. Either way, the idea is to have the nozzle-to-bed separation perfectly consistent across the whole surface -- then you can just tweak the zeroing up and down to optimize the squish. The Wonder Weapon posted:I printed an ABS piece for the first time, and I'm left with two questions. Bottom of the part isn't perfectly planar. You can see pretty clearly that in the non-brim section there are three or four stairstepped layers trying to build it up. Go back to your model and ensure that the lower surface is truly flat. Alternately you can just try printing it on a raft with support material, but fixing the model is the proper solution.

If it's a heated bed there can be slight differences between cold and heated, so yeah be sure to do adjustments under regular printing conditions.

I hastily joined the world of 3d printing recently, after impulse purchasing an Anet A8. I'm just scratching the surface with all this, but man is learning about this stuff something fun to obsess over. Anyways : pictured is my more recent benchy (first one in the background). I printed a few upgrades, a new circle fan duct, a couple of stabilizers for the z axis rods, and a filament guide. Also : turns out my x belt was a bit loose which contributed to my first one looking like drat cottage cheese. next step : tensioner for that belt. Getting there, though. got my pi set up with octoprint, played with some slicers and landed on Cura , and am currently learning Fusion360 (I'd done some dabbling in Inventor for work a decade and change ago, so I have the slightest familiarity with parametric modeling). how fun.

So my printer is now in my basement in cold indiana weather. If my build isnt big enough to self stick, I can't seem to get brim working. Every time it looks like the brim has gaps in between the lines? I set first layer width down to 110% and that seemed to fix it but it still managed to peel up pretty easily. Am I just stuck with rafts until my basement isnt ~5C all the time? E: Sometimes it looks like the brim is perfect and then when it's peeled up it looks like some of the brim has split into groups.
