    I am planning on building KYO's "Sphinx" CNC mill; with some modifications.

    C-beam Sphinx

    I downloaded the B.O.M. to order the parts. As I perused the list, I noticed that the "Z" motor mount was offset; and used pulley's and a belt. Thus it required that the motor be offset. But in my viewing of countless Sphinx "Builds", I noticed a number of times where they used direct motor drives; where the motor connected directly to the lead screw.

    If you would be so kind; would you care to state candidly; the" pros and cons" of both methods; before I order the parts.

    Thanks in advance for your doing this.

    Note: I apologize if someone has already posted this question. If so I hope "OpenBuilds" will delete this thread; for I have no intention of "upstaging" any one; especially since I am new to this great forum.
