So I had no idea when I built my MPCNC how to secure anything to the bed. As a result my first base is pretty messed up now. But of course my machine is attached to it. So I am going to have to take it apart and put it back together on a new, better thought out base.
Anyway, I had a hard time squaring the legs when I started this project. And I think I’d like the ability to move bases more often, or to change the size of my base. So I ended up designing a part to address both problems.
The below shows an early prototype of a piece that is meant to go under all four legs. The conduit goes through it and the leg. Threaded rod will go through the holes on the edges, forming a square. I plan to use locknuts (4 per rod, or 2 per foot per rod) to hold them in place. I should be able to measure everything accurately and ensure nothing can move this way.
Anyway, before I go too far down this path I thought I’d post here for everyone’s thoughts. Is it dumb and there’s some much better way? Are there things I could do to improve it?
[Edit: if it isn’t obvious I printed only the first 1mm of a foot for that test. It’s in the same blue color so it is hard to tell. the foot sits on top of the new piece, and the conduit goes through both, keeping them aligned.]
