>>2992984
Aww, I try my best to include the essence of the last thread. Which one was yours?

>>2992985
The PID Demonstrator. I'm very happy about the design of it all. Well, mostly happy, but I'm no designer and I cornered myself with some choices. Mechanically however it came together pretty well.

>>2992972 (OP)
New thread when the old one is still at page 1 is kinda silly,

>>2993006
Sorry, but I am technically in the right to do it. Last thread oddly disappeared when baking on page 8. I won't make it a habit.

Post it again once the electronics actually work (;

>>2993009
Huh, never had that before myself.

>>2993007
It's not a bad printer. Watch some reviews, but my impression is pretty positive, fixes some of the issues of the original Core One. Looks like there are some less ideal features (like the shitty camera), but it's a pretty moddable printer. If you ever want to upgrade it, you can be fairly sure that Prusa will have various upgrade paths into the future. INDX being a main one. The open source firmware and permissive attitude towards hardware mods is definitely nice.

If you don't want a printer that you can modify or upgrade, and don't care about open source, you are spending a fair bit more money compared to its competitors. That goes not just for the printer itself, but any branded accessories and consumables. If you want a good modern printer without any modification at all, you'd probably be better off buying a printer that comes with those additional features, like chamber heaters and such.

People whine about the BambuLabs drama but barely say anything about the new laws barreling forward that would basically make Bambufaggotry mandated by law

Buy X2D now or wait for Anniversary sale? (I faintly want a H2C, but what I really want is a toolchanger)

Can I assume ironing settings will work fine for the same filament, same brand, different colour or do I have to dial it in for colours as well?

>>2993029
I doubt that anything serious will come of it, 3D printing is too widespread and I don't see how they could enforce the laws they want to pass. That said it sure would be great if politicians could stop being neurotic control freaks for 5 fucking minutes
>>2993076
if you can wait then buy when there's the sale of course, that said even with a discount the H2C will probably still be 2.5-3X the price of the X2D

>>2993078
Yeah. I think the X2D is what I should get, but I do want something like the U1, but with a more contained filament system, not as noisy and not having to pay like a $200 premium to get a plastic lid on the damn thing.

>>2993079
>not having to pay like a $200 premium to get a plastic lid on the damn thing
lmao I just looked it up and that's really the case (well only $150 if you preorder now!)
imho your main questions to choose between the two should be whether you mind the bowden extrusion on the second nozzle, and how often you'll use 3 or 4 colors/materials in a print over just 2

>>2993079
Just do the ikea plastic tub lid, you can stack two tubs to get something with impressive thermal insulation.

Best "tough" cheap pla? Polymaker pla pro is great but I wouldn't be mad at spending less. Needs to stay at the same quality/print ease otherwise I would rather just spend more. Overture super pla + maybe? Will also be picking up in bulk since I've been burning through filament lately, so any bulk offers from the manufacturer are a huge plus.

>>2993082
never had an issue with Sunlu's PLA+ (not the 2.0, never tried that one), last time I bought 3kg of it for 36€ iirc but their website is weird and sometimes the MOQ is 6kg

>>2993082
best pla all around is just regular pla.
I like sunlu's pla 3kg rolls.

This stupid thing. Entirely 3D printed except for the knobs, that I had a small stock of.

Looking into a vertical storage system for my hobby table. I'm stuck between regular pegboard, Ikea skadis, and opengrid.

Any advice/pros and cons? What did you go with?

>>2993134
oh wow, I missed that completely. Thanks for the heads up. Now that its in the thread its more likely to make it in the next one.

>>2993144
pegboard is widely accessible and you can print fixtures but it's better for hanging stuff like tools or a bag organizer (I used to have a wall of backpacks and fannypacks in pegboard) and the big annoyance is if you don't lock the clips they knock out easily.

Gridfinity looks good and there seems to be a skadis based system out there (someone selling on my local cl but I haven't seen it in the wild. There is also multigrid. I don't like the looks of open grid, multi or gridfinity seems best although I think one is locked behind patreon walls. And then do you want to spend the time and money producing all of them? And can your printer handle the quality to make shit actually fit? I always struggle with other people's designs so idk.

>>2993105
high speed pla isn't regular pla, it's sunlu's name for their pls+

PLA+ is the easiest filament to print with tho

>>2993111
suprised we have 0 leaks on this one, we had leaks left and right fro the x2d

hey bitch, those are rubber bands instead of 3d printed TPU belts. delete your post

>>2993111
Larger bedslinger? I have no opinions on this.

>>2993166
TPU works for toothed belts, but it’s not high enough friction for a flat/square belt. To get friction it needs to be under tension, but TPU creeps badly.

>>2993168
>TPU works for toothed belts, but it’s not high enough friction for a flat/square belt. To get friction it needs to be under tension, but TPU creeps badly.
I've literally done it and have been running belts that are fine since 2021

all friction belts need tension, you don't even know how your own car works, are you a bot?

>>2993172
>all friction belts need tension
Yeah, and TPU creeps. But I guess it creeps under bending loads, not as much under tensile loads.

This is the very first thing I actually tried to make from scratch. I keep getting a constraint flip in FreeCAD. Hopefully someone can help me out here. Let me over-explain my process here.

I'm making a little organizer for a board game that I can resize. Just 4 bins divided by a 1.5mm barrier between them. What you're looking at here is the pocket I'm carving. For the inner walls I have the edge of the pocket coming in 0.75mm, then I polar pattern the sketch around the center point of the main body 4 times to make 4 pockets. When I resize the width, the constraint for the inside wall of the pocket flips to the other side of my origin line here, pic related. It looks like I've got the outside walls working, but the line for the inside walls keeps flipping to the other side. I've been googling around and the solution is 'tie the dimension to the variable'. Okay, great. Worked for the outside walls. I want the inside walls to be 1.5mm, any formula I put in there is going to scale the size of the inner wall. This dimension should always be 0.75mm in from the center line. How the fug do I get that set so it doesn't try to flip the constraint? Is the process I'm going through here just flawed from the start? I feel like there is a simple solution staring me in the face but I'll be damned if I can see it since this is my first dive into the program.

>>2992972 (OP)
how do you guys connect filaments? is there a sure fire way to join filaments on the cheap? I saw the method using a silicone tube and a soldering iron and did that, not to long ago that first joint appeared and i was able to watch it and it broke in the print head. The print head started clicking but i was able to push the filament and the feed motor got it and it kept going. I may have over heated it? the joint wasn't a big mess but it wasn't like brand new smooth

>>2993199
Not FreeCad, but I often draw diagonal construction lines from the outer corners to the inner corners, and specify them being right angle/parallel to one another.

>>2993206
Why would you want to do that? To save the few metres of filament left on the spool? Or for multi-colour bullshit? If the former, just use the remnant filament for little useful things like organisation boxes. If the latter, use pauses instead, and if that's too inconvenient use something like an MMU.

>>2993199 That's strange, anon
Are you sure it's a constraint and not a measurement ?
Also is it a horizontal distance constraint ?

>>2993078
>I doubt that anything serious will come of it, 3D printing is too widespread and I don't see how they could enforce the laws they want to pass.
Maybe, but the california one already passed committee, and the New York one is still in the budget AFAIK. I wouldn't underestimate it.

>>2993199
seems that the issue is that FreeCAD doesn't use signed constraints so it doesn't really know what side of the line that point should be on, you could make a little 0.75mm construction square with the bottom right vertex in the center and then constrain your pocket square to the top left vertex.
Also personally I'd just sketch all 4 squares with the appropriate constraints but from what I understand it's bad CAD practice?
And a multi-transform with two linear patterns should give you direct control on the distance between the pockets, but if only need a 2x2 a polar pattern is probably a cleaner approach
>>2993228
that's crazy, are 3D printed gun parts even an actual problem in the US? Can't you just easily scrape off the serial number from a normal gun or create a make-shift gun with normal tools anyway?

>>2993232
>Also personally I'd just sketch all 4 squares with the appropriate constraints but from what I understand it's bad CAD practice?
>bad practice
It is.
Except with FreeCAD it is the most reliable way to get things done, SPECIALLY (and I cannot stress this enough) if you're using some of their "weaker tools", aka anything that uses booleans (or implicit booleans).

>>2993232
I would create a symmetry against the vertical axis to create the second square then another symmetry to create the 3rd and 4th, put dimension constraints on the 1st square then put symmetry constraint on the rest.
>seems that the issue is that FreeCAD doesn't use signed constraints
it should, there's a direction for the dimension constraint and it can be -1, 0 (not applicable) or 1

Something like this

Not really, but Luigi shot the guy with a partially 3D printed gun, and it seems like Western govts are in a mad scramble to regulate personal tech. Also, these states are run by people who absolutely hate the 2nd amendment and personal gun ownership.

>>2993234
but why is it bad, is it just because of scalability or is there some other reason? If you constrain the squares properly everything should still be able to change the variables later, and pocketing one "complex" sketch seems less intensive computationally than making an array with a pocket
>>2993235
>it should
I have no idea why it doesn't, I've also had issues with things jumping around after changing a dimension
>>2993237
I hate politicians so much, completely detached from the reality of their country and taking big decisions about shit they know squat about just to push their agendas. Plenty of people live off 3D printing nowadays or use it heavily, also they want to go against CNC too apparently? What's next, needing a licence to buy a nail gun?

>>2993238
>Plenty of people live off 3D printing nowadays or use it heavily
They don't care about the common people
>What's next, needing a licence to buy a nail gun?
Don't give them ideas...

UPDATE: New York passed their ban!

>>2993246
>New York Gov. Kathy Hochul signed into law on May 27 a requirement for 3D printers sold in the state to have technology preventing them from printing guns.

This is utterly retarded.

>>2993249
It's retarded, but they are still pushing it, it's still a threat to the 3D printing community

>>2993249
>technology preventing them from printing guns
such as?

It will be the CEO class that are forcing the politicians to crack down on this.
They're all afraid of being the next one to get Luigi'd.

you can whack a bloke on the street like Luigi did with just about anything, even a hammer or a rock, and if someone really wants to 3D print a gun he could just build his own printer and use it offline even with the bans...
