komar1970,
One machine at a time. I want it to be the one you have been describing all along in here with the C1 ball screws. We'll address the axis moves soon.
-----------------
How do you have the steppers wired? ie; Series or Parallel

So what kind and quality of ball screws do you have as i have requested in reply #51?

Not all ball screws are the same. The lead can vary, the lead can be different on going the opposite direction.
Lets not get into the lead error at this time since it is just one component of the system.

You calculated the steps  per unit as 400. So you should first check and adjust based on a long travel difference.
ie; If the steps are correct for say 10" and then you try 1" , how much it is off by at 1" will be small as compared to the long distance
if the screw lead error is linear over the long distance. Sometimes that is not the case.

But........I would rather you test a few things to find max velocity and acceleration first irrelavant of the exactness of the movement.

So keep answering the questions, please.

komar1970,
1.THK SR15 is a linear motion "RAIL".                                           
   I want to know the quality of the ball screw you are using. Is it rolled or ground?
   What are the specs for the ball screw? ie; lead deviation

2.Do you have a curve for the motors?
   How many wires do they have? Would be nice if you just posted where you got them and I will find what i am wanting if it's available.

3. Power Supply - 48 volt
   Please answer the questions Ray asked you:
  What is the current rating of the supply?
  What kind of supply - linear, regulated, switcher?
  Did you assemble or put the controller together from parts?
  If you purchased the controller, post info on it.

komar1970,
Please provide additional info on the motors.
1. Are all the motors the same for each axis?
2. Provide a link to the manufacturer or where you purchased them from. Need to know the exact motor model number.
3. Who manufactured the mill ? Provide a link to the maufacturer along with model number.

I noticed the problem is also in the end mill , if the end mill is a little pushed in COLLET runs to the side , and it also gives the parts is larger 0.06mm  on both axes

That's spindle / tool runout and is a different problem. So noted. We will deal with each problem, but one at a time.
Stay focused on answering requested information.

I have a problem with prcision  of cutting  parts , people from MACH3 can not hellp me

We can  help you, but you need to help us help you. The above comment does nothing to resolve your problems.
The people here are very knowledgable, they have been there, done that and produce precision parts.
Knock off the attitude and reply to requested information.

komar1970,
You did not answer the following questions.
 
1.What computer are you using? Dose it have on-board graphics ( is it the Dell)?
 
2.What version of MACH?

My comments below and please don't respond to them.
- I didn't ask for a video. The video can  help as it will allow us to hear what the steppers sound like when you are
 runnning them. I need specific answers to every question that is asked and information on any item we request.
 Stay focused...... please.
- No need to post pictures of your configuration. That's why we  asked for the xml file.

- DO NOT  change that xml file  except as we suggest or as we modify it.
IE; You posted the xml file and the step pulse duration is 2 and direction is 0. Now in your reply #29 you say the pulse duration is set at 5.

komar1970,
1.What computer are you using? Dose it have on-board graphics ( is it the Dell)?
2.What version of MACH?
3.What kernel speed?
4.Run the driver test and post a picture of what the graph looks like.
   How close are the PULSES PER SECOND to the kernel speed?
5.Post your xml file.

komar1970,

This problem is not only with this machine, it was with every my machine

You have numerous machines and computers. Can't tell if you ever realy resolved  any of the posted problems you are having. Some of the threads seem like they never come to a conclusion. I am not sure which machine or computer you are using at any given moment. One would think that after ONE YEAR
you would know how to set the steps per unit, be able to confirm the steps, set backlash ( backlash dosen't go away or get better), and understand if you deviate from the calculated how that relates to axis travel. Sorry if this sounds harsh ....but can't help fix the door hinges when the door is swinging  back and forth.

So keep to one machine, computer, xml file used for the setup, the type of screws  ( are they rolled / precision ground / how supported / etc.).

Maybe I am missing something,

Wanted to try out some code so attached are a few pic's. Was curious as to how the mill would do. Cut the profile of the release button by mistake at 30 IPM instead of 3 ....before I
had a chance to blink  it was done.    Need to play around with the 3d code as I am not happy with the surface finish in some spots.
