Re: Extending the length of ball screw

Hi WT,

The screw is actually 36mm dia, I have two of them one is around
900mm, the other one 400mm. So exstending the lengths is a must. How
much ? well, only a fraction to that of new one. It was the shipping
cost that hurt my feeling. :-)

Yaskawa servo motors, no detailed spec yet, a rough figure X and Y
axis must be 400W, Z axis 200W.(smaller than X & Y, yes, I am
motorizing the quill)
