    OK, on the positive note - all steppers and drivers/ PSU works!
    Am I calculating steps per mm right?
    I have 1605 ballscrew, so 5mm pitch
    So if I want my cnc to move 1mm, it's 0.2revolutions (1/5).
    I have set my driver to 200pulse/rev (http://www.longs-motor.com/productin...12_80_131.aspx) by putting SW5-SW8 ON
    so thats 0.2*200 = 40 steps per mm, right?
    I think I have calculated something wrong as my velocity is set to 31 000 but it moves quite slow compared to CNC's on youtube.
    Btw, is there any point having microstepping turned ON on the driver?
