Re: serious problem

Hi Ray,
the 20 ipm as i understood is the manual or the rapid movement of the axis,
for testing the ballbar i used a feed rate of 10 ipm,
which is kinda slow but i have to live with that (the ballbar can adjust the
feed rate to what the machine is running).
to answer your question ...yes the motors exhibits the missed steps at
different feed rates.
but when i hooked the computer output pulse pin  from one axis to an
osciliscope i found out that the stall comes from the computer...it's not
the
problem of the motors..the motors are 470 oz-in, 1.8 deg/step, and half
step.
as for the computer it's a PII 470 MHz ..which is only  running the BDI
2.10.
am not sure if i can switch to freqmod because the input to the controller
Box (Drive Rack) is a pulse and direction for each axis.
