Hi guys. I have done many small works today.

Firstly I planned to install the motors firstly to make the axis move convinient because the motors have the small handwheels behind. To install the motor in the right position, I milled a smll locating coupler between the ballscrew end and the motor bracket. It's a simple AL part I machined with CNC control.





Fit in very well:


Locating the bracket:


After locating the bracket I could drill the screw holes at the right postion so the stepper motors can drive the ballscrews more smooth with shaft couplers.
