I haven't used CAD in years (I used AutoCAD during engineering back at university), but don't have the time to dedicate so tend to take an Agile approach (I'm a software developer now), i.e. learn as much as I need to get the job done and ask lots of questions.CraigRKhttps://www.blogger.com/profile/08954180125391911304noreply@blogger.comtag:blogger.com,1999:blog-5357805692487690686.post-18115790406269108752010-06-23T02:25:07.260-07:002010-06-23T02:25:07.260-07:00By the way, to get the dimentions of the STL parts...By the way, to get the dimentions of the STL parts you can use OpenSCAD to import the stl's using import_stl(); and then you can use project(); to project them onto a 2D plane, and finally export them to DXF. Once in DXF format they can be opened in QCad and dimentions measured and/or printed onto paper. I think I shall write a post about this I assumed it was common knowlege.Anonymoushttps://www.blogger.com/profile/17207320619551063718noreply@blogger.comtag:blogger.com,1999:blog-5357805692487690686.post-29025709104433182992010-06-23T02:18:05.589-07:002010-06-23T02:18:05.589-07:00I am with Craig on that one, Threaded drives are e...I am with Craig on that one, Threaded drives are easier when you start out, because they are easier to make and because the speed is slower, which makes it easier to control. Print some pulleys then upgrade.
