Hi everyone. Ive just finished my little mill, and it works great, its ardunio based running grbl control software. I thought it would be cool to mill PCBs so I downloaded fritzing, designed a PCB and Im now stuck, as I need something to output an NC Gcode to the mill. Fritzing can output a few different formats, pdf, svg, and grber. I have got Vcarve but it doesn’t like fritzings pdfs, I can import grber file into grbl, but the scale is wrong and the trace looks like its full of errors. Can anyone recommend a PCB design package that is compatible with grbl?

I'm planing on constructing a ball mill out of pvc plumbing parts. So far I have two questions... ~I need some help with how to get a motor to use to drive it, that wouldn't require 'to much' wiring to set up. I was thinking about using a drill and mounting it some how. ~Second, I would like to know where I could get lead or other non-sparking media other than online. For example, I heard you could use lead fishing weights, if they sell this at a place like Dicks Sporting Goods could you please send me a product number? Thank You for your time

Papa is looking into getting a CNC machine for his business and asked me about what to get. I looked into it for a little while but really I have no clue what is going to be needed. We receive imprints (negatives) of people's feet in a floral-foam like substance and normally clean it up a little and pour a mix of plaster into it to get a positive mold, which needs intensive course and fine sanding in a sink, (as well as adding things like metatarsal pads and other custom things depending on the order) and from that point the ordered material is vacuum formed over and the rest of the insert is made. Because of the shape of the feet and added features, it seems like we could cut out the use of the heavy plaster entirely if we use a 3D scanner to scan in the molds and then mill them out with a very basic 3 axis CNC out of cheaper/more light material for the rest of the processing. The question is, what equipment will be needed? I see some of the cheap 3D scanners are really nothing more than glorified webcams and fancy software, while (guessing the much better) laser scanners are pretty $$$. So how can we scan these imprints into the computer as a 3D file? And what are some good cheap CNC machines that can do the main 3 axises and enough to do 6 to 10 molds at a time?

Ever wanted a small milling machine to mill aluminum ? Heres a cheep way to do it. It's not real accurate but it gets the job done. and for under $ 160.00. all the parts come from Harbor Freight (Drill press on sale 70.00) (roto zipp bit 2.99) ( 8 inch crosss vice 39.00) some bolts and thats it ! it's slow so take your time and the vice is a little rought but it gets the job done. Run the drill press at the highest speed on aluminim slower on plastic and use small cuts , don't try to hog out the part it will break the bit. have fun !! There you have it.

Question by tilmen | last reply
I have bought a 1610 cnc milling machine which use .nc gcode files. The machine came with pcb manufacturing software Coppercam. I use Fritzing ( which I find is easy to use and very good for my purposes) to design the pcb and the export the pcb via Gerber RS247. This gives .gbl , gtl, and drill text files that are then imported into CopperCam. I then do all the contours for the circuits and hatching for the board which work fine. Trying to do the drills, if it is not an Excellon file, does not seem to work in that the drill holes do not show on the screen. Fritzing does not export Excellon files. If I look in the drills section the number of holes required are listed. The I try to create an export file that I send to the milling machine. The sample etching templates that came with the machine are .nc gcode files. I have tried all the option of output from Coppercam but nothing works. I would appreciate some advice on both mentioned problems without having to get new software as the exchange rate for south African currency to any other is pure murder. Thank you in advance Atilla the Hun

Factory made mills can cost 1000s of $. These mills can make great valuable lumber from what otherwise might be firewood. http://www.youtube.com/watch?v=kQT4meL1L-Q This one seems to be an adaptation of an existing bandsaw. http://www.youtube.com/watch?v=kQT4meL1L-Q Several videos show machines with car or trailer tires. Although I've used bandsaws, belt sanders etc quite a bit, how they track the blade or belt remains a bit of a mystery to me. How can such mills be made at home? I found an -ible for a _CHAIN_saw mill, but I'm thinking of a BANDsaw mill.

I made a ball mill today. and i made some lead balls out of solder,but the solder contains flux. and i know that acids are not good to have in a ball mill because it can spontaneously ignite. so i was wondering if i could neutralize the acid with backing soda? or does it not matter that its there?

I am taking a class in automated manufacturing this year in school, and thus have to do a few projects requiring laser cutters/cnc mills. So I thought as kind of an extra project, it would be cool to make a case for my iphone 4. So the question: is it possible that I can mill myself an iphone case, probably out of wood (I prefer aluminum/stainless steel but that might just scratch the heck out of the phone), and if so, what type of wood should i use (I am clueless... not a carpenter :D ), any ways, any thoughts, or maybe someone has tried it before? Just though it would be a cool project if I could make it happen...

Hey so iv got this slightly damages USB joystick sitting around my house and it struck me that it could possibly be fun to turn it into a little CNC rig. Figure since its already got usb control to some degree it would simplify things alittle. So what I was wondering was is there some complication that makes this a bad idea that I am not seeing. Thought I would ask before rip the thing apart.

I am going to attempt to make an iPhone case out of metal as part of my local shop class. I have most of the milling (I think) worked out, not entirely sure how it will result due to the thin walls of the case, but its a project :) I am wondering what metal I should use to make the case. Titanium would be cool, but the solid chunk of titanium block used would cost around $100. Not really my idea of affordable. So I have the choice of either aluminum or steel/stainless steel which are around $15 to get a couple iPhone-sized bars. Any recommendations on a strong metal that might survive being milled to tight tolerances? Also, I will most likely be milling this on a Benchman XT mill, if that helps any.

Hey y'all! Firstly, thank you for being a part of the Q & A community. You rule. Secondly, I'm trying to make a book form out of plexiglass. This won't be a functioning book; it will just resemble an open book. For the spine, I'm using steel. For the body, I'd like it to be a frosted acrylic (I checked in with TAP and they have a .75" that should do). However, the acrylic is pricey at that thickness so I'd like to get as much advice as possible so as not to mess the whole thing up. Here's my question: 1) How do I shape / sculpt the acrylic so that it has that nice bookish bell curve? Like so: http://www.lesscakemorefrosting.com/wp-content/uploads/2012/03/OpenBook800.jpg Suggestions I've received: -3D printing (I hear there is one at noise bridge but am not certain it's big enough / available for a non-noisebridger to wander in and use) -Milling (never tried milling before but how hard could it be?) -Sanding (sounds messy. And scuffy. Maybe hard to control smoothness accurately) This will be the exterior for an interactive artist's book I'm building. If you're interested in seeing it when it's done, you can add me on twatter! By the way, if anyone has any experience with coding for the Kinect and wants to nerd out sometime, I'm down.

I am thinking of running machine shop training courses in the UK for those interested in learning how to really use lathes and other big shop equipment. The idea is subject to insurance company permission etc. but I wanted to gauge if there was any potential interest from people here (obviously only those based in the UK, unless you really want to commute) I'd expect costs to be something like 50 GBP per day + materials, and no more than two or three people per session, keeping the ratio of machines to people as 1:1. We'll probably try and do "group projects" as well as bring your own. The idea of group projects is that every ones gets to make more than one of something, to get techniques sorted out, and then we combine everyones work into assemblies - collaboration at its finest.

My friend has an Airsoft pistol that he spent tons of money on, full of custom parts. The upgraded system is so powerful, though, that it breaks plastic cylinders. He was wondering if there is any online based company that would make him a clone of the cylinder, with exact precision, except out of aluminum or titanium. Any ideas?

Question by dpsilver | last reply
I have come across a few 'instructables' which show how to create a ball mill. This mainly uses an electric powered screw driver, a plastic bottle, some ball bearings (I will use lead even though steel would suffice) some epox putty and a vice clamp.. However some points of the instructable was unclear. I came across several electric drills, where the button was situated in a place that meant it was not possible to secure to the on position, also they seem to either go to slow or too fast. Finally with the weight of a significant amount of aluminium and lead/steel balls, I found the bottle section weighed too much and caused stress on the drill bit which caused it to dislocate and fall out, or in the second case.. the motor just gave up. My two questions. 1.is there a better instructable which addresses the problem of supporting the plastic bottle . 2. would a mixture of aluminium powder and charcoal (german dark) work better than aluminium powder? would the ratio of dark powder and iron oxide change? i gather that aluminium oxidises, is that bad? i don't really see how it's possible to avoid oxidisation without the charcoal.

Hi y'all from France! I've been aching to get my hands on a CNC machine from quite some time now, unfortunately I'm quite a noob when it comes to electronics and such. I'd found that while the machine itself is not that hard to build (see all the ables), however the electronics involved are just too complicated for me to build a controller from scratch. I've found the other day some seller on french ebay selling a complete controller without the power supply, so I've been wondering about it but am not in the position to fully understand that piece of equipment. So my question is: what do you think about it guys? Does it seems to be ok (BTW I've also found 3 NEMA23 stepper motors, precisely the same model as described in the specifications for the controller board on its seller's page)? For now I just want a three axis CNC machine capable of cutting polymer foam and soft wood, so I don't really need expensive and powerful stepper motors. Thx for any kind of input!

The MTM Snap is an open source CNC desktop milling machine designed at the MIT Center for Bits and Atoms. The frame, milling head and bed are milled from 1/2" HDPE and are designed to snap together around the other required hardware for fast and easy construction. It's designed primarily for use manufacturing PCBs but the project site lists waxes and plastics as other materials that it can be used to machine. I've been given one to play with, if YOU had access to one, what would you use it to make?

Also tried doing this using a dxf from eagle to lcam, but it puts the holes as big circles (I need points) and the "drill selected circles" command doesn't work... Anyone know what to do?
