It moves!

Motor Mount Shims
So in order to make motor mount shims (which was required due to motor adapter geometry, and unplanned design) I found a piece of scrap composite board. After an attempt to cut it on the vertical band saw (blade was shot.) I moved to a manual saw blade, then a very helpful fellow who works in this shop pointed out a skillsaw I could use. I clamped it to the table, and made quick work of the board, to make 3 simple blocks to shim the motors with.

The last picture shows how it will shim the motor mount.
















With some more milling of the motor mount (which is tedious to remove from the nema23 motor by the way...) Holes were located and drilled through the shim, the motor mount, and the frame. It's obvious to see how i almost had serious clearance issues with these motor mount bolts.















Aside from bending the motor mount by being inattentive, I got it all attached to the ballscrew, and frame. I hooked it up to the computer, and ran some simple tests on mach 3. The same helpful shop fellow recognized that the bolts holding the ballscrew in place were sort of loose (which they are.) The issue is I used some readily available fasteners that don't quite fit right, and can't be completely tightened, so i need to buy some socket head cap screws.

Here is a video of the ballscrew moving via mach 3 commands.
