Milling some clearance for the ballnut blocks under the table.

Worked well with 2 vises, had to remove the moveable jaw to fit the table

The ballnut block for the x axis. It still needs to be bored out to ~1.5"dia to fit the ballnuts, I was going to do all 3 blocks when I get a boring head.

[dave111]

machined the saddle for the ballnut blocks and oil grooves for the lube system.

Limit Switch can be seen in the last photo, I'm using proxy switches, 2 for + and - limits and a separate one for homing. I'm pretty sure mach can just use the - limit switch during the homing routine, but I've never setup switches before so I'm covered just in case I need it.

Here is the Y axis ballnut mounting

[dave111]

Z axis ballnut mount

[dave111]

X axis free end bearing mount, and the fixed end which still needs to be bored like the other blocks.

The fixed end block will house some 7304 angular contact bearings, as well as provide a mount for the motor/belt housing which has not been made yet.

Cheers,
