                  2. Hey Marco,

                    I'm looking at converting a mini mill from littlemachineshop.com to CNC (I'm also in theory building a Long-Ez, but unlike you I'm not making progress...) and I was wondering if you could, now that you've accumulated some experience with your machine, if you could summarize what you're happy about, what you wish you'd done differently, and if the machine's capabilities are generally filling your needs. It looks like I'm going to have similar applications, hopefully including making parts for the Long once I get time to work on it, so your thoughts about this would be helpful.

                    Thanks,

                    /Patrik

                    1. Hey Patrik, nice choice of airplane by the way.

                      First of all, while I am happy I CNC'ed my machine by myself, I would not do it again the same way and spend 6 months of my time machining parts to very tight tolerances, just to see it all “blow up” in my face occasionally in the form of endless problems.

                      I thought I would be saving money by making things myself, and it sure looked like it on paper, but I should just have bought a conversion kit, and get it done in a few days instead, which is what I did with my lathe conversion to CNC.

                      Let's look at what you'd need...

                      CNC Fusion makes a very good kit, look it up here http://www.cncfusion.com/minimill1.html. I would go with kit #5 ($655) since you have the Little Machine Shop minimill, and I’d also get the Pre-Loaded Ballnut Service ($33 x 3), and the Heli-Cal zero backlash couplings ($24 x 3).

                      This way you’d be out $825 plus shipping, let’s say $860. On top of that you need a few more things, check out my blog http://longezproject.blogspot.com/2013/11/cnc-mill-conversion-part-8.html. You can get a controller board like mine pre-made for around $600 (here’s an example http://www.ebay.com/itm/Gecko-G540-4-axis-cnc-stepper-motor-controller-CNC-Router-mill-conversion-/261521423614?pt=LH_DefaultDomain_0&hash=item3ce3e43cfe), or you could shop around and wire it yourself for a bit less.

                      Next you need 3 motors http://www.kelinginc.net/NEMA23Motor.html ($50 x 3), and a board for talking to the controller http://www.ebay.com/itm/USB-MOTION-CONTROLLER-for-Mach3-UC100-/161360698449?pt=LH_DefaultDomain_0&hash=item2591d8dc51 ($150)

                      You’ll also need some other stuff like limit switches, etc. (budget $100 at most).

                      Let see, you are around $1300, but you also need Mach3 ($180), perhaps a computer, and possibly CAD and CAM software. The software alone can go from $200 to $10000, but in a recent development you can get Fusion 360 for free (http://www.autodesk.com/products/fusion-360/overview), register it after 30 days as an enthusiast or small shop (less than $100K in revenue), and renew every year. Or register as a student or professor, and renew every 3 years.

                      So we are really talking about a minimum of around $1600, plus computer and software. When you consider the price of the mill and a small computer, you are going to be in the neighbor of $3000 easily, without tooling.

                      When I purchased my minimill I had no idea it would lead to CNC, or that it would be as much fun as it has. Knowing what I know now I would have bought the biggest mill I could afford, since the upgrade cost is not much different.

                      To be honest, this minimill has been perfectly capable of machining everything I threw at it so far, although you have to become creative at times on how to hold on to what you are trying to machine due to the small table size. As an example look at how I had to machine the brake pedal brackets. It took 6 repositioning to machine them, versus just 3 had the table been slightly larger. This increased time and frustration quite a bit, but it is what you have to deal with with a hobby level mill.

                      As minimills go, the Little Machine Shop one is the best of the bunch, so you are already ahead of me there. Give me a shout if you have more questions.

                      Ciao, Marco.

                  3. Thanks for that detailed response! It pretty much goes along with what I've been thinking, although I don't think I'll go the Mach3 route. I have some experience with the embedded motion controllers like grbl and TinyG, since I've used them for a cnc router, so I'll just hook it up that way, at least for a start. I'm not that worried about the electronics part since I have much more experience there than with the mechanics.

                    A larger table would probably be nice, but it looks like the cost, space needed, etc, start going up quickly and the marginal increase in capability sure won't be anything near going from no mill at all to a small one! I think the mini mill is a very reasonable compromise.

                    Thanks for mentioning the Fusion 360 alternative, by the way, I hadn't heard of that. I've been using Cubify Design (http://cubify.com/Products/design) which is a cut-down version of Geomagic Design for $199, to design some parts. I'm quite happy with it, it's very capable, but has the huge drawback that you can only export parts as STL files. While most CAM software seems to handle STL, it approximates everything with planar segments, so round shapes won't be preserved. I'm not sure how big a deal this will be in practice, since you can set the resolution. I guess I'll just try and see.
