6 bolts hold Billy's ballnut adapter in place. You'll need to insert the adapter first and then hold it near the top of the column while you add the 6 bolts.

I'm using Billy's ballnut adapters for the linearmotionbearings2008 rm2005 ballscrew/nut. When I put it on the machine the screw wasn't right and the top piece would not align. It was because of this set screw preventing the ballnut adapter from mating flush.
6 bolts hold Billy's ballnut adapter in place. You'll need to insert the adapter first and then hold it near the top of the column while you add the 6 bolts.
I also had some flashing that I needed to remove from inside the column that may have interfered with the ballnut adapter.
I also noticed that the inspection screw plate at the back has a really long screw that may also interfere. I removed it for now and will add a smaller screw later.
I need to double check the setscrew at the bottom of the ballnut mount but I can't get to it without removing the head. I tried removing the center screw and the lock screw on the head but I could not get it off the machine. What is the best way to remove the head?

Got the Z moving tonight...the best I could do is 200IPM without stalling....

Which type of coupler did you use for your Z axis?
I used oldham couplers from misumi.Originally Posted by Signal9
There you go, that's looking better.
A good start, you can tweak it later once everything is finished.

Nice! You have more guts than I do! 120IPM still gives me heartburn trying to make sure I didn't miss a tool offset somewhere.
CNC: Making incorrect parts and breaking stuff, faster and with greater precision.
Today was certainly an adventure...I worked on the Y axis. I had to make a trip to the store to get a 9/64 alan key so I could take the billy mount for the y apart. I needed to take the tube off so I could transfer punch a hole for the bottom on the mill. Someone needs to teach this boy how to drill a hole at 90deg angles in both vertical and horizontal. I was off a bit but able to make it work by slightly elongating the bottom hole in the y stepper mount.
When I got it mounted I noticed that the channel the cut is not centered. I'm not sure if that is normal or not? The ballnut is very close and I may need to grind that side down a bit in spots.
