For ACM - like aluminium honeycomb?

ACM is more of a sandwich. Aluminum, plastic, aluminum.

I have a boring old klicky. It works very for me 🤷

We probably have the same model - the one with the big oval stand. Every once in a while I wish it was OLED and/or higher resolution, but it’s not worth the expensive or all the modern “features” such as these.

I personally am pretty happy with my 2.4, although I would suggest skipping the cable chains and going to an umbilical. I went the nitehawk route. If you’re going to be printing ASA or ABS add an under bed carbon filter and bedfans. I would also suggest skipping to ACM panels if you plan on big ASA/ABS prints.

If you dig through my comments you can see me talking about it. Mechanical bed leveling, that actually squares the gantary to the bed, and Z calibration make for very consistent first layers.

$1,200 is Voron and RatRig territory. Vorons cap out at 350 mm³ for build volume and 500mm³ rat rigs are $1,550. I agree that plenty of folks are probably over buy on printers, but if you want this kind of build volume the price seems reasonable - especially for a printer that ships assembled. Personally, I went the Voron route and if I wanted a larger printer I would probably either just make my 350mm taller or go the RatRig route.

That said, high velocity on a large format printer isn’t that useful for big prints IMO. You’re probably going be running a bigger nozzle and laying down wide/tall extrusions, which means you’re probably going to be limited by how fast your extruder can melt plastic. That’s the case on my Voron with a Rapido HF with “only” a 0.6mm nozzle, 0.8mm extrusion widths, and 0.3mm layer heights.

Agree, but also - what if they aren’t declined and that’s just the way they were all along?

I have a coworker who’s a total idea factory, but struggles to communicate their ideas clearly. They’ve found LLMs grestly help writing their ideas in a way others can understand.

TBH, I am not that fond of the idea. After all, if a LLM can write what I do there’s not really a need for me. But I also wonder if I’m gatekeeping a bit. Even if I have a hard time empathizing with the situation, I understand that we all have different strengths and weaknesses. Maybe they’re just using a LLM to help fill in one of their weaknesses?

These units are somewhat silly IMO. It all comes down to volumetric flow. Big nozzle + thick extrusions + thick layers would probably mean needing to print slower than that speed due to the ability of a hot end to melt the filament.

For quite some time now, Marlin has been the firmware of choice for any kind of custom 3D printer, with only Klipper offering some serious competition in the open-source world

Confused Voron noises

It does seem like an interesting concept, but I wonder how much benefit it will have, both in tuning effort and final outcome.

That’s probably the same one we have, or at least a closely related sibling.

Mine has two different speeds it follows, but yes - it doesn’t move very quickly. You can also mess with the angle of the sprayer which will impact the amount of water delivered to the area it covers.

That’s good to know! We’re trying to get some seeds to start, so I’m not watering that deep. It seems like our first good spring rain drives out a bumper crop of worms - they’re all over the street. My kids enjoy going for a walk to collect them in a bucket to put them in our vegetable garden. That usually happens before the robins arrive though.

I got this one at my local ace hardware. It’s Nelson branded, but this general design has been around decades. I’m sure thrt are a number of different mechanical underpinnings. We’ve had this one 7 or so years in and it’s holding up well. It makes covering a large area very easy.

Same! It’s a great design if you’re lazy and want to cover a lot of area. I bought this one at a local ace 7 or so years ago and it’s been going strong with minimal attention.

And I’ll be the first vendor!

1 and 5: Either should be fine, especially if the seller is reputable and has reviews. Many sells will have a store on multiple sites, but in some cases people will resell other people’s work. See if you can track down the original creator to support them 2: I suspect everyone will want STLs they won’t have to do any processing on. What do I mean? Well, I could give you a STL for a piece that’s massively too large and would need to be split into pieces or a different STL that will be impossible to print well. I suspect print services won’t want to deal with this, will charge for it, and/or you might not be happy with the final outcome 3: If you’re paying someone to print the parts, they will likely have larger format printers. However, this might cost some $$ 5: It depends how thick the designs are and how strong you want them to be (more perimeters = stronger), but keep in mind that you’re also paying for machine time and potentially processing (eg surface finishing, support removal, etc). To get a feel for a quote without buying this design, find some cosplay armor on something like printables and use that for quotes

I had no idea this was even going on, so that’s a potential plus.

Stratasys filed the two lawsuits against Bambu Lab in the Eastern District of Texas, Marshall Division, in August 2024. The company claims that Bambu Lab’s X1C, X1E, P1S, P1P, A1, and A1 mini 3D printers violate ten of its patents. These patents cover common 3D printing features, including purge towers, heated build plates, tool head force detection, and networking capabilities.

I had heard that Stratasys was a bit of a patent troll, but some of those claims are news to me.

Can confirm, klipper does this too. Sincerely, someone who had a few thermistor related wire breaks.

Adding encoders to your steppers, or buying stepper motors with built in encoders, can help a lot but it’s not a cheap solution. It can also be a bit bulky, so packaging them a printer not designed for them can be tricky.

I also free hand. Every once in a while I wish they were more perfectly square, but then I realize I don’t actually care enough to print a fixture and have to deal with attaching/detaching my Weller.

Nice photo! Why would you delete it?

I suggest checking out this post. I have quite a few replies about the voron experience.

TL;DR - agree that a Voron can be a start and walk away printer. Building it will take some time, which isn’t necessarily a bad thing but know what you’re getting into. It will take some configuration and tuning to get it printing, but the Voron initial setup guide and Ellis’s print tuning guide are very easy to follow.
