Well, I'm finally back to where I can get around and so out to the shop a little more. Made some parts and have redesinged some of my original plans. Not that I was working from prints or anything. Except for this Z assembly. I had originally decided to set up a brake on the Z just for safety. After having finishing and assembling the thing, it doesn't seem like I'll need one. The bearings I used for supporting the ball nut are so large (and the fit in the brackets are a little tight) that there seems to be enough resistance to keep the Z in check. I plan on having a counter-weight now anyway, so the brake will probably go. I'll keep my options open, however. |
