So the last couple days I've been working on my work holding capability on my machine ...
Here are a few pics of what I got done today ... the tracks for the vertical overhang:
This should handle most of the long pieces.
Then I started out on the triangle bits ... it's hard to describe just how much hardware is involved for each chunk of track ... each one gets 12 bolts so it won't flex no matter where I grab things:
And then mounting the triangle bits ...
Notice that the board overhangs the rails some - this is my attempt at keeping some of the dust off those X rails. It may prove to be futile ... but it might work out. We'll see.
So now I'm about ready to flatten. But before I do, I think I'll dial in the screws/steppers so that all the distances mach3 says to move are actually moving that distance. Once the top surface is flat, I'll work out ensuring each axis is square.
