    What am i doing wrong here... I've just tried to work out the gearing speeds and thus linear speed of my rack and pinion on the X axis.

    The set up looks like this:

    The max operating speed of the motor is approx 4000rpm. Its giving a linear speed at the rack of 1.8m/s which cant be right its the slowest machine in the world.

    Have i just slipped up on some units somewhere?? I cant spot where i am going wrong.
