    Get an external motion controller. The parallel ports on Acer and Asus motherboards are not great, I have tried both of them and know. If you do not want to afford a motion controller, get a second PCI parallel port and see what you get but chances are you will still be having issues.

    When I moved Y ... after 200 mm ...300 mm I am receiving that motor knock ...
    Does it happen at different points when you apply different speed or steps per mm?
    If at the same point then check the mechanics.
