    There was a stretch of time I was looking at videos of budget gaming PC builds and they’d be like “How to build a gaming PC for $150” and a lot of them went like “Buy a used Optiplex for $120, max out its RAM for $30, then use this GTX 2080 I got from nvidia for free because I have two billion subscribers.”

      Me: Should I buy a prebuilt 3D printer?

      Reddit 3D printing sub: Oh, heck no. I put mine together for $18.22 plus some spare parts from seven printers I got of craigslist for $1 from some widow. Only took me three weekends to do it, plus a couple hundred hours to update the firmware to match the parts and troubleshoot it.

      Me: Uh, so does it print better than the one I could just buy?

      Reddit: Well, I’m still tuning it for all my filaments. I’ve been through about 40kg, and I’ve got a trashcan full of benchys though. The last few have been pretty good.

          Yeah, I made nearly that mistake. Twice, actually. First with a monoprice, then a creality. I probably have more money in upgrades on my CR10s than I have in the purchase, and I still haven’t upgraded the board. I keep thinking I’ll fix it but I’ve resolved to strip a couple of parts and throw it away. My Prusa XL preorder came last month. I made one update to it (for better TPU performance), and printed one QoL add-on (nozzle wipers). That’s it. I’m done. It prints like a dream, multi-material supports are indistinguishable from magic, and even swapping nozzles is fairly quick and easy. Now I’m (almost) exclusively printing things for my other hobbies rather than worrying that something on my CR10s will fail or need re-tuning.

        Yeah those communities are wild. Before I bought my own printer I thought 3D printing is mostly fixing your printer and buying better parts and bed leveling and tuning etc.

        Wasn’t looking forward to it so I bought an off-the-shelf printer with minimal assembly from a “boring” Chinese brand - couldn’t be happier with it, it just prints without any hassle and I have no urge to switch firmwares or tinker with the printer itself instead of with the printed stuff. To each their own I guess.

        (Still plugged in a raspberry pi for octoprint and did some initial calibration for the filament of course …)

        There is something to tinkering your own machine to the best of its ability on a budget.

        But if you just want to 3d print, nowadays there is no need to build your own. Premade are pretty great.

        It would be very very impressive if your CNC machine can produce and assemble electric motors, wiring and circuit boards from raw materials. But then it would not be a CNC machine anymore.

          Sure it could. A 5 axis CNC head could mill out the shape for a motor and be given a tool that spools out wire… It wouldn’t be easy, but it could build a motor with just that

          It could also be given a head to solder circuit boards

          CNC (computer numerical control) refers to the control systems rather than the act of milling materials, a 3D printer is a sub category of CNC. They can even use the same control boards.

          You also usually process materials before putting them in - they’re good at detail work, but if you start with a block of steel you’re going to lose a fortune changing out expensive heads (and take forever). So it’s fair to assume you’re not using raw materials

                  Makes it harder for your competitors to undercut you in prices. Not impossible, just harder. Most locks are just to make something more difficult so you give up. They aren’t impossible.

                  Another likely reason is that the price varies based on material/labor cost and they don’t want a set price being advertised. The price probably dynamically varies.

    Just ran into this like a week ago with a wood working video. “How to flatten a board without a planer!”. The whole premise was that planers are expensive, so here a little trick for hobbyist… The next scene was them using a router table jig that’s like 5x more expensive then any planer.

        I’ve got plenty of hand planers, but hand planing isnt something you’d want to do for a large piece if you don’t have a lot of time on your hands.

        Plus the larger ones that you’d typically want to use for flattening a large board can run you more than an actual planer.

      So have you found a solution for that? I’ve also run into the exact problem when i tried to flatten a board and all i can do after getting disappointed is using hand planner/electric hand planner 🤣

        A possible solution in a pinch is to get an already flat surface, ideally larger than your board. Cover it in something that will transfer (ink, paint, toner etc). Rub the face of the board you want to flatten across your flat surface**. The** transfer substance will pass onto the high spot in your board. Scrape, chissle or sand the high spots down slightly.

        Repeat this until most of your board is marked by the transfer substance. Your board will be mostly flat (or at least as flat as the reference surface).

        This technique is used in metal work, but it’s labour intensive. For woodwork to achieve sufficient flatness planes are quicker and produce a better surface finish. But if you don’t have any large ones, this method might work if your desperate and don’t want to buy new tools.

        For a less accurate flatness. Place the board on the flat surface and push in the board to fell the points in contact with the flat surface. Then take those parts down.

        The solution I have found is a sander and realizing you will never be perfect.

        Look for the imperfections in the garbage they sell at the store. The bottom of your kitchen table. The inside of your kitchen cabinets. Those are the mistakes they’re trying to hide.

        There’s a pretty easy solution if you have a decent plunging router with a good flattening bit head.

        I set up two 2x6" along the length of my board I want to flatten, and then made a jig box for my router. The jig box is able to slide back and forth while resting across the 2x6, using the depth guide to keep the cuts at a level depth as you do your pass overs.

            I mean, kinda? But a lot more basic wood working people already have access to a plunging router compared to a planer. One you can find new for 100 bucks or used for next to nothing, and the other is like 500 for a janky one.

            Owning a router is a pretty standard purchase for anyone using power tools for woodworking, and if you don’t have one they’re pretty easy to buy for cheap on Craigslist.

        There are some professional woodshops or wood suppliers that will run wood through a planer or drum sander for a fee. I have seen $50-100 for a table top size slab, double that if it has resin. So call around.

    That machine costs well over $381k. We had a much smaller 3 axis lathe installed in the machine shop I worked in during my early 20’s and it was $3M. That was 25 years ago, so it probably costs infinity dollars now, given recent inflation. Hell, you probably can’t even buy them now, just lease them on a subscription for eleventy bajillion dollars per year.

      Adam savage is a godsend, his build tend to use the tool that’s either inexpensive or it can be replicated with another tools. His philosophy is always “hiding the crime” so the imperfections is always either out of view or is part of the charm. Perfect role model for a maker just starting out.

        Adam just got a 3D printer, it took him until late last year to get one.

        Granted his passion is the process to make things and a 3D printer just skips all of that to make something inferior in 1:100th the time and effort, but you would think a gadget lover like him would have had one for years. I can’t wait to see what he does with it.

          As a modeler, 3D printers are a bit like AI art to an artist. It’s fast, it can do some things that are nearly impossible to replicate, but it feels like a hack or a crutch at times. Part of the thrill of old-school modeling (for which I’m neither old enough nor patient enough) is taking very basic, simple shapes and making something realistic out of seemingly nothing. Adam is absolutely from that school. And - like AI art - to go from almost good to presentation quality is nearly as much work - or more - that just building from scratch. As a long time model rocket enthusiast, my printer is an amazing utility. But for some of the really intricate models, I have a lot less pride in the final product because I know I just pressed a button and it popped out.

        It’s honestly more of an arrogance thing. I have a nice drill, screws and different types of cold glue. I don’t want my projects to be anything like the crap I see in 5 Minute Crafts, so I avoid the tool. I know, it makes no sense, but so far I have never really needed a glue gun.
