hi thanks for the help so far for my problem. However having tried all the ways sugested, Im still having problems. units are set to 1 as I am useing a 1mm pitch feed screw connected to a 200 step motor and a 1/2 step/dir driver. If I use IO_exercise then it all works corectly, but no amter what value i place into stepper.ini it still only turnes 1/8 rev. Ive tried input_scale of 200/400/5080/12000 and it dosnt seam to change it. The startup confirms that it is useing the stepper.ini file. If there is any one using a simmerlar setup could they send me a copy of there ini file so that i can see what iam doing wrong Thanks Jason Cox --
