I built a cardboard enclosure around my poor old i3 clone to get my Voron parts printed. It was a bit janky, but it worked and I can now say that my i3 clone can totally print ASA.

But agree that not having an existing printer at all does make for a potentially harder build, especially as figuring out all the parts you'll actually need ahead of time can be somewhat challenging.

I have a 350mm 2.4 and chose it specifically because I tend to make bigger things. The flying gantary is super cool looking, but it does come with a downside: all your tool head cables, if you switch to an umbilical instead of the cable chain, and your filament run have to accommodate the gantary getting ever higher if you have a tall print. It's not an unsolvable problem, but it's also a problem that doesn't exist if the bed is the thing that moves.

One of the pluses of a Voron is that it's enclosed, which means that you can print ASA/ABS for pretty rugged prints. This means needing to preheat the chamber - especially for larger prints. On a big printer this can take quite some time, and also requires some insulation, but there really isn't a way around it without doing something silly like putting a heater other than the bed in the printer. Fortunately, if you're printing a smaller part you don't have to worry about preheating.

A three final thought on a big prints:

  • when prints get big enough basically everything will warp without a heated chamber. This is especially true for ASA and ABS but is also true for PETG. I haven't tried a big PLA print, but I imagine once they pass a certain size they'll warp too
  • if you want fast prints you should look at wide extrusions and thicker layers. I run a 0.6mm nozzle basically all the time with 0.8mm or 0.9mm extrusion widths and 0.3mm layers. It's all about how quickly you can lay down plastic in mm^3. This will make your bottleneck your hot end
  • even with chunkier layers big prints can take a long time. I printed a speaker and it took something like 20 hours for the biggest body and it was "only" around 280mm in circumference and 270mm or so tall. Granted, if I could have fit this on my i3 clone it would have probably taken 5x longer due to a much weaker hot end.

There are bigger printers out there, but between warping and print time I don't know that I would personally want one. For the rare times when 350mm isn't enough I can always split parts, but that hasn't been an issue so far.

Most Voron folks will usually suggest building as close to stock as you can initially and going from there. LDO's kits modify the stock BOM quite a bit, which can make for a more challenging build. Buying from someone like West 3D. Formbot kits use to stick to the stock BOM fairly well too.

As for support, there's an active discord server and forum you can use to get help. They also have a print it forward program where you're matched with a Voron owner who will print your functional parts for the cost of material.

3 hours in and no one's brought up VoronDesign? You can't buy their priners or parts directly, you either have to self source or buy some variant or "BOM in a box" from a third party. I've had mine for two (three?) years and although the build was long it was very well documented, via a 240+ page lego-like build manual. It's a great printer and community.

I don't otherwise like Hershey chocolate, but their chocolate syrup on good vanilla ice cream slaps.

Sorry for the delayed reply. No, too warm won't cause warping. However, the hold side of your hot end will at best be ambient temperature. If it gets too warm you can clog your nozzle.

My view is "if the chamber doesn't need to be hotter why make it hotter?".

If you were printing ASA/ABS you want your chamber to go basically as hot as you can get it though - especially if you're printing something big.

This is the deepest I've ever seen Jerboa render comments.

Old.reddit.com has slowly been getting worse. Lots of collapsed comment trees, a similar posts section after the first two comments in a busy comments section, etc.

Lifting on the corners, especially if this was a bed sized print, was probably due to warping. It stinks that it took out your bed, but warping probably wasn't the cause there.

My main printer these days is enclosed. When I print PETG on it I'll pop the lid open because PETG doesn't like to be too warm.

[–] IMALlama@lemmy.world 5 points 3 weeks ago (5 children)

That looks like somewhat similar to an ultrabase bed. I have had one of those on my i3 clone for years and years. I've also printed a reasonable amount of PETG on it. Was the print and/or bed warm when you tried to pull it off? Prints detach much better when cool.

We had a shishito pepper plant last year. It yeilded way better than our bell peppers ever have. I really regret not planting any this year and will be sure to plant some next year.

Like you said, they're really easy to cook and taste great too.

The ender 5 isn't a bed slinger so it should be relatively compact for its print volume. You can certainly get a smaller printer. You can do this by getting a more compact printer and/or sacrificing build volume. If you want compact you're probably going to want a coreXY

For example:

  • your ender 5 pro is 552mm x 485mm x 510mm and has a build volume of 220mm x 220mm x 300
  • a Prusa i3 mk3 is 500mm x 550mm x 400mm and has a build volume of 210mm^3^ (the bedslinger is indeed bigger)
  • a 300mm^3^ Voron 2.4 is 460mm x 460mm x 480mm and has, well, a 300mm^3^ build volume. They also have a 250mm version that will probably save another 50mm in every dimension
  • a Prusa mini is 380mm × 330mm × 380mm and has a build volume of 180mm ^3^
  • a Voron 0.2 is 230mm x 230mm x 250mm and has a build volume of 120mm^3^
  • I gave up on finding dimensions on the salad fork, but it's probably going to be even smaller than the v0 due to using 15x15 extrusions instead of 20x20
 
 

The coaster is shivering timbers at Michigan's adventure.

 

We saw a pretty good amount of them in our yard this June. It was nice. I can't remember seeing many lightning bugs for years.

I've seen Robbins around our lawn sprinkler before... I'll have to keep my camera more handy in case they show up again

 

Moths need love too!

 

This is a vaguely arty shot I took with my A9ii when I was renting the 70-200 f/2.8.

200mm, f/3.2, ISO 100, 1/800

 

I have a cheap/quick/dirty deer and rabbit fence around our vegetable garden. The doors are simple PVC squares with deer netting that used to attach to the fence via hooks at the top. This design turned out to be very fiddly. The new design seems much easier to manage - simply drop the door section into its slot.

So close, and yet so far

I took this a few months ago through one of our windows. I have a small backlog of photos to get through and hope to do one a day, but some of them might show up on !photography@lemmy.world.

A9ii w/ Tamron 150-500 @ 374 mm, 1/250, f/5.6, ISO 200. Cropped some.

 

No idea what's going on / it's the first time its flowers have ever looked this way. I personally think it's kind of neat.

 

Title basically. I've found myself playing youth sports team photographer, which I don't mind doing but we're going to have two kids in little league this season and I'm not looking forward to culling two team's worth of games. I've gotten better at framing and catching fielding action over the past year, I get pictures of my own kids, and the rest of the parents on the team seem to appreciate the photos, so woo. But! I'm very interested in tips to make the process of culling shots a bit faster.

Each game I try to get a hero shot per kid batting (getting a hit, bonus points if the ball is in frame), along with some general fielding shots. I come home with a metric crap ton of photos since getting a hero shot basically means bursting any time our team is at bat for every pitch.

I try to make sure each kid has roughly equal representation in the final album, regardless of how many (or few) hits each kid actually got.

I've found that it's easiest to sort photos by kid and cull from there, but I'm doing this completely manually in photo mechanic. I've dabbled in AI tools, but I don't really know what's out there. It seems like sorting all the photos with the most prominent face in the frame, and using context of being mid burst if a face is lost, automatically would be a massive time savings. Does such software exist? I don't want to pull out every face in the frame, just the biggest/sharpest one. Is there a better option for youth sports? A better approach to apply in photo mechanic?

Any/all advice welcome!
