I need more information from you to see where your problem is. What is the
Input Scale and Output Scale set to in your ini file? Mine are both set to
2000. Also check you max velocity settings in the [TRAJ] and [AXIS]
sections.

My setup moves 1" for 2000 pulses from EMC. So at 500 IPM that is 8.3 in/sec
for 16.7 kHz pulse stream from EMC. With the Pentium 333 you should be able
to do better than that, but actual machine speed will depend on your gearing
(input scale and output scale settings in the ini file).

The tuning parameters on my ini file:

P= 800
D= 0
I= 0
FF0= 0
FF1= 0
FF2= 0

I don't have the ini file handy but I can post it later if you anyone is
still interested.
