throwaway81523: I'm not too excited by the idea of making little plastic precision gearboxes for robots, so when PLA printing isn't good enough, I mostly want to machine metal. Not car parts or firearms but flashlight bodies, knife blades, small tools, that sort of thing. Nothing wrong with robotics but there are other interesting areas too. I think the article skips over that a little too easily. That said, it's a good article.

throwaway81523: 我；我对为机器人制造小型塑料精密变速箱的想法不太感兴趣，所以当PLA打印不起作用时；不够好，我主要想加工金属。不是汽车零件或枪支，而是手电筒主体、刀片、小工具等。机器人技术没有问题，但还有其他有趣的领域。我认为这篇文章跳过这一点有点太容易了。也就是说，它；这是一篇好文章。

syntaxing: Former MechE for a decade and I owned personal CNC routers and on my 6th 3D printer. The biggest issue with CNC is the cost for consumables and accessories. Need a special bit? $$$ Need stock to cut? $$$ Want a nice ER11 or R2 collet set? $$$. A nice vise? $$$ Cut something wrong with a carbide bit? Shrapnel explosion. 3D printing has a bunch of limitations but is a way better machine for hobbyist. But I have been eyeing the Millennium Machines Milo. A very fair price point for a traditional style CNC. You can also decorate it however you want with your 3D printer.

syntaxing: 前MechE十年，我拥有个人CNC路由器和我的第六台3D打印机。CNC最大的问题是耗材和配件的成本。需要特别的一点吗？$$$需要减持股票吗？$$$想要一套漂亮的ER11或R2夹头吗？$$$。一把漂亮的虎钳？$$$硬质合金钻头出了什么问题？弹片爆炸。3D打印有很多局限性，但对业余爱好者来说是一种更好的机器。但我一直在关注千禧机器，米洛。对于传统风格的CNC来说，这是一个非常公平的价格点。你也可以用你的3D打印机来装饰它。

sottol: Shameless plug if anyone is interested - I'm working on a $600-ish open-source, reasonably capable, but small and somewhat "tidy" hobby CNC machine with BOM cost around $600 that requires some DIYing.It's meant to be an alternative to the Desktop CNCs like Nomad, Carvera, Bantam, ... moreso than a PCNC or other proper entry-level CNC.The ultimate goal is to make it hobbyist-friendly, capable of easily cutting alumin(i)um and not taking up a lot space, not being messy or loud enough to require a dedicated workshop. Unfortunately, cutting metal is inherently loud so you probably would not be able to run it in an apartment as I'd hoped.I've made a couple decisions around being friendly for people coming from the 3DP space around probing, using roborock CPAP as chipvac, running it mostly dry, fully enclosed. I'm also starting to work on computer-vision-based probing and the idea is to later enable a host of more user-friendly and safety-focused features and maybe integration with Kiri:Moto's CNC mode for "guided" CAM and so on - basically a beginner-friendly CNC that guides newbies using an integrated web-interface.More info on Github: <a href="https://github.com/thingsapart/mini_nc">https://github.com/thingsapart/mini_nc</a>GH is a little outdated but I've been using the little machine to cut alu for a while (mostly parts for itself) and it's working quite well. There's more videos and such on the Discord linked in the GH readme - feel free to ask questions on the Discord, I try to respond as quickly as I can. The full model with all its components is completely open in Onshape (I know it's not ideal but how I learned CAD - link also on GH).

sottol: 无耻的插头，如果有人感兴趣-我；我正在开发一个大约600美元的开源软件，功能相当强大，但规模较小，有点&quot；整洁”；带BOM的业余数控机床成本约为600美元，需要一些DIY 它；它旨在成为Nomad、Carvera、Bantam等桌面计算机数控系统的替代品。。。比PCNC或其他合适的入门级CNC更先进 最终目标是使其对业余爱好者友好，能够轻松切割铝，不占用太多空间，不会太乱或太吵，不需要专门的车间。不幸的是，切割金属本身就很吵，所以你可能无法像我一样在公寓里操作它；d希望 我；我做了几个决定，对来自3DP领域的人友好，使用roborock CPAP作为芯片真空吸尘器，使其大部分干燥、完全封闭。我；m也开始致力于基于计算机视觉的探测，其想法是以后实现一系列更用户友好、更注重安全的功能，并可能与Kiri:Moto集成；s CNC模式用于“；指导&quot；CAM等-基本上是一个初学者友好的CNC，使用集成的web界面指导新手 关于Github的更多信息：<a href=“https:&#x2F；/ Github.com&#x2F-thingsapaut&#x2F/mini_nc”>https:&quot&#x2F；github.com；分开的东西；mini_nc</a>GH有点过时，但我；我已经用这台小机器切割铝有一段时间了（主要是自己的零件），它；他工作得很好。那里；GH自述文件中链接了更多关于Discord的视频等内容，欢迎随时就Discord提问，我会尽快回复。完整的模型及其所有组件在Onshape中是完全开放的（我知道这并不理想，但我是如何在GH上学习CAD-link的）。
