Replied by PCW on topic My setup Process confusion
Some notes:

AXIS = X
MIN_LIMIT = 0
MAX_LIMIT = 18
MAX_VELOCITY = 30 ## 30 IPS is very fast (that is 1800 IPM)
MAX_ACCELERATION = 75 ## 75 IPS/S is pretty slow for a 30 IPS machine
(0.4 seconds/6 inches to full speed)
TYPE = LINEAR
SCALE = 8128 ## note 8128 steps per inch * 30 IPS = 243.840 KHz which exceeds your
drives capabilities and also is not reachable with STEPLENGTH and STEPSPACE = 2.5 usec
This is why you got the warning, STEPLENGTH and STEPSPACE = 2.5 usec means
the maximum step rate would be 200 KHz.
STEPGEN_MAX_VEL = 15.0 ## This should be ~37.4= 25% larger than MAX_VELOCITY
STEPGEN_MAX_ACC = 75 ## This should be ~93.75= 25% larger than MAX_ACCELERATION
FERROR = 0.05
MIN_FERROR = 0.001
DIRSETUP = 100000
DIRHOLD = 100000
STEPLEN = 2500
STEPSPACE = 2500
DEADBAND = 0

Also, is your scaling correct?

The 7I96 (and all of our Ethernet FPGA cards) can generate up to 12.5 MHZ step rates
but of course this requires very short step pulse lengths (40ns,40ns)

PCW thanks for looking this over.
Steps per inch: This is how i came up with that figure. 1600 microsteps on driver. I believe it is 8*200=1600. the ballscrew i found a figure 5.08TPI.. here is the math that i think should have been used. 5.08*1600=8128

The pulse input frequency of the driver is 200KHz.
I am thinking that means I cannot exceed that number.
the document also claims that pulse width minimum of 2.5 us.
another claim is minimal direction setup a minimum of 2.5 us.

I am looking at one of the tormach ini files for (reference). Well it looks like i made a soup sandwich!

1800 IPM is not realistic for a step motor/ball screw system.

1. Your motors will not spin that fast (>9000 RPM)
2. If your motors could spin that fast, your ball screws would likely whip you to death
3. 180-300 IPM are more reasonable limits (that's 3 to 5 IPS in the ini file)

PCW i agree that speed is catastrophic.
I am currently editing .ini file
is 8128 pulses correct, by chance?
If you have any other advise on the timing it would also be well received, also.
Thank you.

well it works so far...after the recommendation. Thanks! Out of curiousity. How did you come up with those numbers?

And installing the touch probe.
And tool offset touch pad.

1. The stepgen velocity and acceleration values should be about 25% greater than the
axis and joint values.

2, The Axis and Joint values need to be reasonable for step/dir+ball screw machine
3 IPS=180 IPM is a good value to start, The acceleration value was chosen for 0.1 second
acceleration to full speed, a good rule-of thumb for mills and lathes. Note that your
overall velocity limit of 2.25 IPS (135 IPM) is what will limit velocity.

You can of course raise these values to get better performance or lower them
if you get stalls or drive faults, but when you adjust them make sure the stepgen
values are always larger by about 25% than the axis and joint values.
