    It'll work with some, usually older ones, but it's not recommended.

    Most laptops do not output the full 5 Volts on the parallel port output pins so the step and direction signals are not seen by the BOB etc. There are however some break out boards that will accept 3 Volt incoming signals but as Ger21 has said 'laptops are not recommended for use with Mach'.

    Smoothstepper is probably the most popular external motion controller.

    I'm running one with my laptop. They're not cheap, and not without some drawbacks. Support has been minimal, and there is no backlash compensation last time I checked.

    However, they do work well if you can ignore those pitfalls. $165. I would call Arturo at CNC4PC. He can either sell you a Smoothstepper or a breakout board that works on less than 5V.

    Best,

    Info on the Smooth Stepper can be found at their website :- http://www.warp9td.com/

    There are additional issues with using a laptop, not least their energy saving features and multitasking preferences.
