2016 Is the Year of Buying CNC Tools Instead of Building Them (hackaday.com)
szczys writes: We have reached a turning point in personal CNC Tools like mills and laser cutters. Up until now, your options were to drop some serious cash (businesses) or spend time to build them yourself (individuals) at moderate expense. But over the last year the number of companies making CNC tools and the software available for them has matured. Anyone looking for an entry level machine in the coming year will find that purchasing equipment has a better time/price value than building yourself. The best part is, these entry level tools have the precision you need if you still want to build your own high-end or extreme-spec machines.
CNC: Computer Numerically Controlled
Not sure when indivuals built CNBC machine. Unlike 3D printers, the milling machine actual can cause. Lot of damage if they break. I also know they have been inexpensive suite case units for at least a decade., say for $2k. They require some skill, so not as popular as the 3D printer.

Where have you been for the past 40 years or so?
OK, let me actually read the article, and see WTF they are talking about vs. the almost certainly misleading post title... I suppose they mean, like "personal CNC"...
Oh, I see. We're talking about "desktop CNC printers" and "hobbyist CNC Mills".
Is it really that hard to come up with a title that expresses that, or at least include it in the body of the post? No? Too much to ask?
The reason I ask is that you've been able to buy CNC tools easily for the past 30-40 years or so, if my memory isn't failing yet. Because I remotely remember writing Z-80 code for the first microprocessor-based CNC controller a long, long time ago! (They were all minicomputer-based before that, and mainframe going even further back. BTW, Allen-Bradley bought the company that I wrote that code for...)
So, yea, the only people buying CNC machines back then were GM, Ford, Chrysler, Boeing, their suppliers, etc. etc. etc.
The truth is, this could have happened in the 80s, if only there had been Harbor Freight! Z-80's were certainly affordable to hobbyists. What didn't exist - I don't think - was decent, affordable, small mills. No reason it couldn't have happened were there a demand.
So, the excitement over 3D printing is past, and now people are realizing that there are CNC mills too?
Did we have to wait for affordable, powerful processors? Funny, that 4mHz Z-80 could run a 5-axis mill, with the position loop(s) running in the Z-80 (not in the specialized hardware used today.)
I wrote the code for those position loops. And counted every machine cycle by hand!
So, yawn. Big breakthrough.
It seems like Hackaday is just throwing a bone to the places offering turnkey mini CNC machinery.
You can still get a bigger machine cheaper by DIY-ing it, but that depends on if you have more time or money really.
That, and the fact that with CNC {metal} machining,,,, it really isn't possible to get a fast & accurate machine by bolting together pieces of t-slot beams. (I don't think I've seen even one you-built-it CNC router that used ballscrews).
I think that their will be more competition in this area in the future and I'll be able to get what I want
I hope so, but I don't think there's going to be a quantum leap in performance with the laser machines until you can get a decent beam-steered galvo head + flat field lens for under a few thousand bucks.

There are some Chinese vendors that you can get a sub-$2k laser cutter from. There is a guy somewhere that sells a board that converts them from their proprietary software to a generic open source friendly printer driver. They aren't the best (I think it's a 40-60W laser) and require some work (cooling system etc) but they are darn cheap and relatively precise for most prototyping.
Renting the things (even 3D printers) is still the best option unless you are a business or want to rent it out, I have access to a number of tools at my job but the amount I actually use them vs other stuff I need to do (most of the time goes in the design, not the printing/cutting). If you don't have access to a maker space, there are sites online that let you find other makers in your area that have (access to) these large tools you need only once every few months.

My company sold a pretty nice knee mill for scrap which was only a few hundred. We also scrapped a few hundred pounds of tooling like chucks, vices and other holding tools. Sad day.
Seriously? Wow, I should add CNC machines to my bland.is (Icelandic craigslist/ebay) search list. I've always thought it'd be great to own one but the price tag for a new system has always been astronomical.

I'd really like to buy an Epilog laser but the ones that I'd want are about $26k, which is pretty expensive for a machine that isn't going to be used to make money
Then make money with it. I recommend 500 yen pieces - they're only 7 grams each (a bit more than a quarter) and worth nearly $5. The right mix of melted down pennies, nickels and copper scrap should give you the right alloy. In Japan you can buy almost anything in vending machines, so just make sure your coins past the electrical conductivity test and you're golden.

The actual number of home projects that the average "maker" will complete in a year makes the cost of buying your own machinery very expensive, when you amortise the cost of the equipment (and the learning failures) across the number of successes. However, since with many "makers" the actual hobby isn't having and using the end product, it's the joy and anticipation of buying new toys and the fun of playing with them - any actual working pieces are simply a side-effect, then more toys is the way to go!
politicians are like babies' nappies: they should both be changed regularly and for the same reasons
Up until now, your options were to drop some serious cash (businesses) or spend time to build them yourself (individuals) at moderate expense.
What's with the stuff in parentheses? Why can't an individual "drop some serious cash"? And why can't a "business" build their own at moderate expense?
systemd is Roko's Basilisk.
Prices of even new CNC mills and lathes has recently (last 10 years) come down massively. 20-30k can get a decent small working volume machine new these days. Even the extras, like end mills are way cheaper now. It is already at the point where it can be cheaper to get your own for small volume rather than outsource it to machine shops. Assuming you have the in house expertise.
My problem is space. My last mill and lathe was in the inlaws garage which is now full of junk.

There's a big difference betseen $20-30k (which I don't have) and a few hundred dollars + a pickup (which I do have). ;) I don't have personal experience with CNC mills but I am the sort of person who regularly takes up projects building / modifying things (often metal) by hand, and I'm a programmer, so given the two I doubt I'd have trouble learning.

It probably wasn't CNC and if it was being scrapped it probably wasn't even DRO equipped either. Not to say it wasn't a good, solid machine, but it was probably large, heavy and awkward to use. That said, CNC retrofits are available for old mills, though they're not cheap. Probably worth it if you've got some huge old bridgeport that's stillin good nick.
A company my friend works for has one though. I think it was an old retrofit on an older mill which they got very cheap for some reason I couldn't quite follow. There was this bloke Dave, right, I think and he knew a guy... Trouble with the old ones is the replacement parts are nonexistent and they're rather finicky "software" wise, though I think that's a rather generous term for what goes on inside the old CNCs.
SJW n. One who posts facts.
I suck at welding too, although I think my 1960s MIG welder is partly to blame. Or at least that's my excuse ;) And I have to admit that I too have some amateur rocket concepts myself that I'm really itching to try, though I need to retire a few existing projects first. I've got one rocket concept that I'm working on simulating in OpenFOAM involving a caseless LOX/aluminum/paraffin/polyurethane rocket that burns itself up in its entirity. First the channels of open-cell polyurethane foam saturated with LOX burn, then paraffin surrounding them (while their honeycomb aluminum substrate provides compression), then melting and atomizing the aluminum into the exhaust stream (where it provides extra heat to the exhaust), with the exhaust expanding via a virtual expansion nozzle (the point of the cfd simulations is to figure out what geometry yields optimal expansion while not complicating manufacture). It'd be really neat to know if it works out in the real world. But I need to finish the artsy gate for my land that I've been working on first at the very least, and probably a few other projects too, I can't keep accumulating them whenever something else jumps into my head ;)
Don't get me wrong, I love coding. But you're absolutely right that there's something particularly special about making something that you can touch and interact with :) And (with the exception of welding well) I usually find that things are easier than they sounded at the outset. For example the other day I was restoring a late 1800s pressure gauge and almost didn't even try to get the dents out of a brass ring because I "don't know how to do bodywork". Turns out that it's no harder than just finding any flat-tipped metal tool, a hard surface, and making a bunch of little taps on the tool with a hammer as you move the tip around - after polish you'd never know it had once been banged up.

This may make you want to hit me. I understand. Let me see if I can type this out properly.
Last spring, I bought an Axiom AutoRoute Pro (8 - I think?) along with the stand and a bunch of stuff to go with it. It's still sitting in its crate with a bunch of boxes of stuff that goes along with it. It comes with a stand, a giant tool box, and a bunch of other stuff.
I understand that there's a kit to do laser cutting and engraving and I think I might have that with it - I've never opened it. I seem to recall that there's an attachment to do 3-D printing with it but I did not buy that. I'm pretty sure that I got the laser cutter and the engraver heads. I think it was from Axiom. I could root through my email and find the order and figure it out. I should be able to access that from here.
*sighs*
No, I've never opened it. I've never taken it out of its crate. No, I'm not even sure why I bought it. Well, no... I know why I bought it. I want to do some engraving in wood with a laser 'cause it looks like fun and I had a project in mind.
It's still sitting in the crate and has boxes piled up around it. I don't know what I spent on it but it wasn't all that bad until I added a bunch of tools to go with it and the laser head. I'm pretty sure that's what I ordered. I either got the laser or I got the 3-D printer kit - I don't think I got both. I'm thinking that I'd have not ordered the 3-D printer because I can't think of anything to make with it.
Yes, yes I do stupid things with a remarkable regularity.

I still have to work hard to restrain myself from buying stuff like that. I nearly got myself a $3500 Boxzy.com CNC/3d-printer/laser-engraver, but managed to resist and instead just bought some more cheap electronics project stuff (total ~$100).
Not sure why/what changed in me/life but I don't remember this urge to buy stuff to do projects in the past. In the past I had more time and less money I guess, so I just did the projects I could afford to do, rather than spending small amounts of time and large amounts of money buying supplies/tools for projects I don't really have time for. Well, maybe when I retire in another 20 years...

Yeah, I got extremely lucky and was able to retire at about the age of 50. It's almost as if, "Hey! I couldn't do this when I was a kid! I want this toy, I promise I'll use it!"
They say that when you have the time you don't have the money and when you have the money you don't have the time. Except, well, I have both the time and the money and there doesn't appear to be an adage for that. I'm not sure what happened - I went from being a "maker" (when such wasn't a thing and the resources were far more difficult to come by) to being a passive consumer.
I don't write much software any more. I barely put together my own computers. I haven't soldered anything in years. The only thing I do take the time to do is make stuff from wood and then I go on binges where I'll stop for a year and not even visit my shop. I'll buy stuff and it will stay in crates. I dunno... I've become a passive consumer in so many ways. I've accumulated a lot of tools, so there's that.
I'm slowly working my way back out of what seems to have been a funk. I'm not sure how it happened. I can, quite literally, buy anything I want (within reason - I guess) and so I do. I think that might be part of the problem - I can just buy anything I want. I've made some steps in the right direction, I guess. I've converted to using Linux exclusively (I used to be a Unix user) and I've invested in a girlfriend. Err... Invested... Yes, I've invested time, emotion, and even finances. It does sound cold to put it that way but it's slightly less so than saying 'acquired.'
So, I don't do resolutions but this coming year does look like it might be a bit different. I've got a few other things that will be keeping me occupied and, hopefully, that will be impetus to change and start doing things that I've been meaning to do.

If you are looking for something fulfilling to do, you might think about setting your shop up as a maker space to help educate disadvantaged kids...

That sounds great but I live in a town with 0 kids. I don't even live in a town - I'm in an unincorporated township, about 24 miles from a small village. The village does have a school and I provide them with lots of goodies. They're cute little buggers and invite me to their plays, concerts, and games. In return, well, I've outfitted the entire school with iPads, netbooks before that, and will probably do the Macbook next time around. (Apple gives a pretty decent discount - I've interacted with them before, it's a little slow but not bad.)
I do, on the other hand, let people use my shop if they ask - and if they can do so safely. I also let them use my garage and tools so long as they're safe and clean up after themselves. It's a *very* small community. There are six houses with full-time residents. The closest is about a half mile and I've reached an agreement to buy their property. I'm not a recluse so much as I like space to stretch out.

I can a get a 15 ton (metric) truck with crane from anywhere in this city to anywhere else for about $500, including pickup and delivery. The problem is here is not moving it. It is the space on the factory floor.
