    The most cost affective way for you at this moment given your limited CNC knowledge is forget Speed control from software. You'll hardly use it anyway and from what I'm reading having to Cam the spindle speed for each tool and material will cause you trouble at first while learning.

    So the cheapest solution is buy Potentiometer and fit to VFD for easy manual speed control. Cost about £2 and fitted in minutes. Search the Forum and Clive S has explained how to do it and whats needed.

    Then buy one of these and control the VFD ON/OFF using relay using Output from bob. Even the crapest Bob's will control this.
