Ken we might be thinking differently....
Like when you see the pics of the flanged Ball Nuts there has to be a preferred method of attachment from the flanged nut to the back of Y or Z carriage.
On my Z axis I bought an Isel Ball Nut set in a housing with a 2 hole flange that will bolt onto the Z carriage.
But for the Y axis where I am using a Delrin flange nut there is no housing assembly etc, so I need to make something to move the Y axis.
does this make sense?..
