If you plan on using dual leadscrews for the Z axis, you'll need 4 motors w/4 axis board to run it. Some uses a belt drive to run both X axis with only 1 motor though (so can get away with a 3 axis motor), but of course 4 motors are better/more reliable.
From my experience (95% finished my 1st build) and from what I read on older threads (and just started a thread about this), you'll learn alot from your 1st build and probably will build a 2nd one soon afterwards from the things you've learned. One thing I'd recommend is not skimp out on linear bearings. Most DIY uses skatebearings riding on a V channel, like on my 1st build. I'm upgrading to real linear bearings on my 2nd build. I can upgrade to real leadscrews and leadnuts easier in the future(unlike linear bearings would).
I bought Rockcliffe plans for my build. Stared at it for a week then decided which way to go. Now I know what to look for, using my own design for the 2nd one w/o any plans. The plan's still worth it for learning experience in the end. Also alot of plans has full sized printouts you can glue to wood and just cut on the dotted lines. From what I understand Solsylva's plans is probably the most detailed and complete plans you can buy
Also for a spindle, it took me a little while to research old threads for opinions, and ended up getting a Hitachi M12VC per old threads' recommendations. Search the model number on this forum for more info if wanted  |
