Does anyone do this as a hobby?

Probably not, but worth a shot.

how homebrew?

I flirted with the idea of doing the research to what I would need for a machine to drill out circuit boards. I had no intentions of building it all from scratch but I suppose there probably exist some very detailed information out there to show you how to do it.

Work dominates me these days and my entrepenurial spirit is dieing bit by bit.

11/17/2005 12:19:03 AM

homebrew as in removing stepper motors from heavy duty printers

as to purchase as little as possible

mounting a rotozip as the cutter

etc..



drilling out circuit boards is def a good use for it, you're right. something im intrested in as well

guy sitting diagonal from me is building his own 4 axis mini-cnc. But it's not all scrapalot shit. He's making it so he can make precision parts for medical instruments. Fucker is a nut anyway.

So far he has been machining parts since August, pretty much all day every day. So it's probably not worth the time or cost. Especially when you can buy a little 3 axis for a few hundred bucks

11/17/2005 12:51:47 AM

few hundred hmmm, must be really small

11/17/2005 1:06:20 AM

we had a little one in high school and if i remember correctly it was still around a grand
cant imagine what you would get for just a few hundred

11/17/2005 1:49:24 AM

talk to ahmet, he knows a guy that built his own. basically some motors and a manual milling machine are all you need. there are a decent number of kits and instructions out there

I think they carry both in stock actually.

11/17/2005 3:43:08 AM

yeah noen see those fucking handles, thats were the computer controlled motors are needed

and hence

there is a site out there somewhere where you can upload your solidworks file and they will produce it for you at a cost.

11/17/2005 4:27:34 PM

^

now we are getting somewhere, i could design the parts to build the machine


this is terminator 2 shit here

11/17/2005 4:28:42 PM

quinn,

I'll ask my friend what the site is and post the address later.

He's not off work yet.

They wont let him use AIM from inside Langley

woot just hopped on

http://www.emachineshop.com/

caution, results have been mixed. Its also not solidworks... but some homebrew thing. But since we're talking about homebrew

thanks man



ps: i think your car is cool

11/17/2005 4:55:54 PM

emachineshop is cool and all but part costs are fucking ridiculous. if you don't buy anything in particular bulk, you pay out the ass.

11/17/2005 4:59:08 PM

might be time to give the uncle a call, i just need to learn this cad/wtfever software before i bug him to waste his time

11/17/2005 5:01:44 PM

I just spec'd out this part:


to be made out of 6061 aluminum, powdercoat finish, about 3"x1"x.5"

came out to $8.79 per.

11/17/2005 5:33:25 PM

what quantity to get that price?

11/17/2005 7:47:25 PM

100

11/17/2005 8:53:44 PM

^^ yeah, and if you want a number closer to 1 it'll be more liek a couple hundred.

11/18/2005 12:41:57 AM

thanks cornbread

ive found a multitude of websites

cnczone ive been reading for a few days

i would really just like to meet with , and talk to someone in person who has built/uses one

Adapting that to be automated isn't $texas or even all that difficult, relatively speaking. You will DEFINITELY need access to a machine shop to make a cnc anyway you look at it though.

which is kinda the catch22 of the whole deal.

RELATIVE TO WHAT?

WHAT THE FUCK IS IT WITH YOU SMUG SONOFABITCHES?

You're the guy that acted like building a autocross brusier would be cake walk, and have retreated to making up pretty weak excuses as to why you aren't finished WELLLLLLLL after you thought you would be done.

11/18/2005 8:33:34 AM

its not the difficulty, its the fact that those cost 500$ and arnt even halfway to what i need.

11/18/2005 8:34:47 AM

^^relative to the fact that you want to build a high precision piece of metalworking equipment. If you already have in mind to make something that requires a fair bit of technical skill to do, then its not much of a leap of knowledge to actually building it.

I never said building a car would be a cakewalk, but it's not all that fucking difficult technically either. It takes time and money. And it's still being worked on bitch.

Also the fact that I have been watching a guy BUILD A FUCKING CNC FROM SCRATCH since August, I can comment at least a LITTLE on the cost, time and difficulty of doing so.

^

There is no fucking way in hell, even homemade, you are going to be able to make a full CNC for under a grand, unless you get nearly everything donated. It just isn't going to happen. Just the cost for materials alone is going to run you more than that most likely.

Most of the home cnc projects you will read about are done by people who already have mills and or lathes, or work as machinists or have access to a full metal shop. And still, most of them start out with a prebuilt mill, like the cheap ones I referred you too, and retrofit them, because it saves you a TON of money over fully fabricating everything and purchasing the motors and drive components yourself.

So to answer this, yes, but not for you.

11/18/2005 6:54:02 PM

now if all you want to do is use it to cut out paper and circuitboards (aka a dremel with a couple of stepper motors) you can build the whole thing out of legos and have what you want.

but if you want something you can use to cut real material (wood, metal, acrylic etc), then cobbling something together is going to have constant problems, and will be imprecise as shit.

im not even going to argue with you noen, lol
