Ball Mill Help? Answered

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

Milling PCBs with grbl?

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?

CNC mill Q's?

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?

DIY Milled iPhone case? Answered

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...

CNC Mill From a joystick.

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.

CNC mill stepper motor controller

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!

How do you make more accurate tools from less accurate ones? Answered

I was wondering, in a general sense how people make more accurate tools from less accurate ones. More specifically, I was reading about reprap and it said it was possible to make components of itself from other previous repraps. However, the errors in them would compound and make less and less accurate/precise models. Therefore there would be some limit to how many times it could replicate. But, for instance. A lathe requires an accurate/precise leadscrew to control x axis motion. Using a lathe it is possible to make another leadscrew however this would be less accurate/precise than the one already on the machine. So for my true question. How do they make more accurate ones than the previous ones. If all the current lathes in the world are +- 1mm then how would you make the next set of lathes that are more accurate/precise than that without a piece of machinery that originally had better accuracy. (sort of a chicken and egg problem) Is there some type of machine or algorithm or something that allows a machine to make something that is more accurate/precise than itself. Thanks

What material to use to mill iPhone case? Answered

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.

Milling machine cheep from Harbor freight

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.

PCB Milling: Eagle, Visolate, Lazycam, Mach3?

Has anyone figured this out? I make a gcode file using visolate for traces and pcbgcode plugin for holes. I then load the gcode from Mach3 to LCam to adjust the two gcode files so they are "matching." Problem is, the drill file (or holes) don't show up on lazycam. 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?  I feel like I've been hitting my head against the wall for hours...

how many watts does my rock tumbler use?

I just bought a rock tumbler off ebay. the brand name is "chicago power tools". its a basic 3lb capasity rock tumbler/ lapidary rotary tool. now, because i live in australia, i have a problem, my power outlets produce 240v , and the rock tumbler can only take 120v, and so when i pluged it into a power adaptor (us-aus), the transformer gegan to work, then overheated and produced smoke, fortunately it still works . now, i am going to go and buy a stepdown transformer and have learnt that if the device is using more than 90% of what the transformer supplies, the transformer will overheat or break or something. now, on my tumbler, and everywhere a description for it is put, it mentions nothing on wattage consumption, and so i am asking , how many watts will it use so i may accordingly select a stepdown transformer for it.

Will hardened lead antimony balls wear out quickly in a ball mill?

I've read that regular soft lead balls can wear out extremely quickly and contaminate mixtures in a ball mill, but what about these hardened lead antimony balls? I don't really fancy the idea of breathing in a lot of lead dust after a couple hours of milling. http://www.pyrocreations.com/inc/sdetail/11961 Would it be a good idea to get the lead balls from this website (found under "ball mills and media") for my ball mill (for making potentially explosive chemicals)? I've considered getting brass balls, but they are unbelievably expensive. I've also considered getting a brass bar and cutting it, but that's not cheap either and I don't know where to get a brass bar. Plus, apparently brass wears down quickly too, so it seems like a lot of trouble when I can just get lead balls, as long as they don't wear out too badly.

What kind of stepper motor should I get? - for 3 axis cnc desktop mill

I am currently working on building my first desktop CNC mill, I plan on it being 3 axis and the spindle being a dremel tool. I am searching for stepper motors that will work for my project and would like some suggestions as to what kind/which ones I should buy. I have seen ones from 96-200 steps/rev, does this make a large difference which end of the spectrum I use? I figure the more steps,the more accurate it can be but for my basic machine would 96 step/rev be sufficient? aka what kind of accuracy can I expect from 96steps/rev? Should I get bipolar or unipolar? Does it matter if the controller connects through USB or parallel port? is there even a difference Thank you for your time
