Got started on the Z-axis mount. Here's a picture of what will be the stepper motor mount. It's 3.625" x 5.25"

I decided to mount the plate on the face of the Z-axis crank assembly.

I don't think two, 10-24 screws is enough support, so I decided to add a couple more.

Here I'm making a drilling jig to bore the two extra holes in the casting.

It will also serve as a drilling guide for boring the mounting holes in the aluminum plate.

And here is the casting with the two addition threaded holes.

Here's the mounting plate with the mounting holes in place.

Next I'll need to machine the mounting holes for the stepper motor and finish machining the contours around the outside.

Hi Chuck,
Those four holes that attach the mounting plate are at an odd angle but they were not shown on your drawing?
Can you share them please.

I'm almost finished. Ball screws are all in place on x and y, steppers mounted and moving nice and smooth.

Thanks

George
