    My compressor is a wee 12gal 110v. Constantly running will trip the breaker along w/ the mill.

    Re: Z Axis Motor Selection

    You're saying that 48v, instead of the 5.5v, should be used to calculate W ?
    Then it would be 288W.
    But still a null point, considering 1) max amperage of driver, 2) no room for a 1:3 pulley.
