Look at Tompson in the US for small ball screws. They have three styles of nuts. They are expensive because they are spec'd to have micrometers of error. I was going to buy from Tompson but ordered a Chinese 16mm screw and found that within my ability to measure the Chinese screw was perfect. But all I have are some normal test dial indicators.
Again, these stepper drivers are not going to accept command lines. They all use point and click based software. To set a limit you just fill in the field and click "save". The trick is in finding who is the manufacturer and then going to their web site and getting the software.
