Funding Unsuccessful This project’s funding goal was not reached on .

Update #7

Project is climbing slowly . . .

7 comments

Don't want to be negative here, but just a realist & state the obvious . . . The curve is not looking too promising . . . I suppose I thought there were more people out there who would be into it.  I suppose I also thought that there were more people familiar with 5 axis machines & CNC in general.  I even have this posted in 3 different places on CNCzone.com, I think the percentage is smaller than I thought.  There's still a chance it could take off though, still a chance.

It seems to me that maybe most of society may still be in consumer mode & this project is all about being a producer . . . although if people did get it they would find out just how amazing, economical, and within reach CNC technology is.

I never worked with, had or saw a CNC machine (except through CNCzone & other online resources) before I designed & built my first one . . . I'll  share all I can about how they work, what they can do, & how to make them, I have several build logs on CNCzone:

Plus there are many more builds there on CNCzone, many much nicer than mine - take a look around if you haven't already.

(+ a few more on my site)

plus this short primer that I made for a Methods & Materials Class I taught:

Well, I'll keep plugging away, trying to share as much info as I can . . . If there's anything specific you want to know about, let me know . . . if I don't know I can suggest where to find out maybe. 

Thanks again for your support everyone!

Cheers,

      Hi Mike,

      Great project, but if I may make a suggestion to start off smaller. I think that to gain traction with the masses, you should consider a smaller build table and use NEMA 23 or 34 motors to drive it. Rather than start off at 10' x 5', go down to 2' x 3' or so, or even smaller (maybe even RepRap size?). You will get a lot more people attempting a build with something that can potentially fit on a bench-top, than take up an entire garage. Once that is going, scale it up to the full-size model. I am currently building a 3-axis CNC and am a member of various online forums (including CNC Zone). Although I am open to being proven wrong, I think that the majority of CNC users are in the small to medium set-ups (by medium I mean up to say 3' x 3') and a few are building 4' x 8' systems. If you look at a distribution curve, the high-point would probably be around the 2 x 3 or so. IMHO, the sweet spot for gaining traction with the masses would be a system that costs less than $2k to build. The current full-sized one would be a bit more than that I am guessing!

      Anyhow, I love the concept and came across this project when I was looking at going to 5-axis from 3!

      Guy, that's some great input. I have been thinking about something just along those lines, maybe edit this down to just the B/C head, or 4+5 axis head plus some concepts about rigidity & gantry design. It would be another project altogether, but may just accomplish the intent of getting the 4+5 axis technology out there more. I like the idea of the Grasshopper definition, that could be something pretty valuable to make. Would have to be available in other formats so as not limit to only GH/Rhino users. Thanks Guy for the input!
      Cheers!

      Mike,

      Amazing accomplishment on your CNC machine! It's rare to see as custom design take the extra step to 5 axis machining. I think it's indicative of the funding so far that 52 of the backers pledged just 1 dollar for your set of plans. I think your other pledge level offers are not something that people generally want. I am going to offer unsolicited advice here, but I think a more fundable project would be to document your A+C or 4+5 axis head design with instructions on your system and how to upgrade 3 axis systems to 5 axis. I think its not feasible for many people to build a 5' - 10' - 24" machine like yours, but the knowledge of making a 4 + 5 axis head would be a valuable addition to the DIY community. To my knowledge the only option for that is Doughty Drives's B+C axis head for a few thousand dollars sized specifically for a small spindle. Perhaps a grasshopper model of your 5 axis head design which sizes for different spindle size/weight's? I know I would gladly fund that for more than a single dollar.

      I would love to build one of these beautiful machines! It's so difficult to come up with the cash and time with a family and full time+ job tugging at my limited resources, though. Oh, if only I won the lottery... I would throw down on your $7,500 package in a heartbeat.

      Mike: I also like to build things but in all likelihood, will never build or own a CNC, but I do know how valuable they can be. I see your efforts as a way to help the garage builder/inventor to stand on your shoulders and improve your machine to make it even easier to build and use. Also, the garage builder/inventor could more easily make or improve products. It seems like a great way to help all of the budding entrepreneurs out there and for that, I applaud your efforts. I am unemployed and only wished I could have supported you more. Best of luck. dug78@aol.com in Sarasota, FL

      You're right Lino . . . It is still climbing steadily. We still have time.
      Thanks!

      I wouldn't be too discouraged Mike. Slow and steady wins the race. There's still 22 days to go!

    Once the funding goal is reached, it should take approximately four weeks to assemble all of the documents into a set of plans/instructions that will include 3D CAD models, some 2D CAD drawings and cut files, hyperlinks to suppliers, parts lists, and concept explanations. This set of documents will be available for download from www.calvinodesign.com. Thank you for your interest. Cheers!
