We use drivers HY-DIV268N-5A and the stepper motors are KL23H

If I test and put the "Steps per" to for example 4000, then the axis move a lot faster, but the distance they move does not match the distance in the "Distance Window" in Mach3

Thanks for your quick response!!
The drivers are set at full step.

About the ballscrew and the leadscrew, the problem is that they are in the machine and I can't determine their pitch. I am fixing an already existing machine, and making the controller between the computer and the motors.

Yes I presume they are direct drive.

The travel in Z-, Y- and X-axis is about 40 cm.

The machine is an Emco F1-CNC

Hello!

I'm a newbie in Mach3, and I have some problem with the speed of the axis in my Mach3 CNC machine. I think this is probably a really easy problem to solve, so for a pro this might take a sec!   

I have set the system to metric, e.g. in mm's. By measuring the distance the axis move when I use the program, I have calculated the "Steps per" to be 200. My stepper motors turn 200 steps per revolution, which means that one motor revolution moves the axis 1 mm in linear distance. The kernel speed is 25KHz, so the maximum velocity should be 25KHz/200 steps per unit = 125 mm/s

However, this feels like a very low velocity? This is the maximum velocity the machine will move, right? What can I do to make it faster? Or am I missing something completely now?
