Hi Aaron,
In your control box, your step and direction have to be kept well away
from all your drive power and motor cables.
Ghost step and direction signals can be INDUCED in your step and
direction lines if the motor or drive power cables run parallel to them.

I don't have the full list at the moment, and it's unnecessary.

I am building CNC tool grinder.
The feed for tool grinder should be from 0.00025 to 0.001 of the inch per
minute.
The servo motor must perform at this feed perfect to make a good grinding
job.
I will use direct drive and my ball screw has 5 pitch per inch.
So talking in degrees, 5 times 360 =

What are the specifications of that screw and nut?

I bought everything from company that represent company from Taiwan, and
it is 20 mm in OD and pitch 5 mm. that screw only as a demo to show how
slow it can go. Real machine will have much larger OD of ball screw.

Hi Aram
I don't think it's the diameter that's important (unless the forces on
the screw will be very high). The important specs have to do with screw
pitch error, preload on the ballnut, and also the end bearings. A good
screw will have maybe 0.001 error over 1 foot, the best I saw with a

accuracy of machine is important but feed should be low enough to grinding
wheel can do the job. grinding of solid carbide is slow process. screw may
be 0.005 inaccuracy but feeding need be very slow to do the grinding.

Hi Aram
I don't think it's the diameter that's important (unless the
i forgot to say that all good grinding machine have linear incoder or
scale alog a axis so inaccuracy of ball screw will not effect final out
put of servomotor.
am i right?
