THe steps per inch are contorlled by the leadscrew pitch, reduction and CPR count of the encoder mounted on the servo motor. Its hard to change the screw or reduction on an existing machine. Its easy to change the encoder count. I have 1000 line (4000 CPR) encoders that combined with everything else gives me 24000 steps per inch. If I were to change the encoders to 500 line encoders that would be 12000 steps per inch. Mach2 is capable of 50K steps/second. Thats about 400 IPM. A bridgeport would be dangerous at 400 IPM. You can either change encoders or lower the existing encoder resolution with the EDIVIDE from USDIGITAL.com.
Roger PS. Mach2/PMDX-120/Gecko 320 reliably powers my 24K step mill at a little over 120 IPM and thats fine with me. Its bigger than a Bridgeport. The G200X will get me up to 180 which was the original rapid speed. Its not a big issue or I would have done something a while back.. --- In [EMAIL PROTECTED], "shadi_salhab_78" <[EMAIL PROTECTED]> wrote: > Hi Ron, > > I wana ask you what is the reduction ratio of the timming belt you > are using to get 120 IPM .
