 Hi everybody,
It has been a few days...
In the meantime i corrected everything and just tonight i finished the cabling!
Everything works (theoritically) as expected and all the signals are coming in and out of the controller OK.
Tomorrow the first test...
I will report accordingly..
Thank you Hood and Dan13 for all your help! Without it i would not have done it...

 Now that all is working properly does anybody know what mode is better for lathe use Speed mode or Torque mode?

 FINALLY!!!
SUCCESS!!!
I checked the second drive's encoder this morning.Hood you were right! It doesn't change numbers both directions the same...
It appears that the second drive's output to the csmio is damaged too.Perhaps i burned that second line driver as well! I have a second chip so i will replace it and see.Problem is i was trying to setup only the first axis all the time.And i was going crazy! I thought that the drive's output (z axis) was ok there (since it was giving readings to mach but the readings were wrong.I just did a quick tune for the (repaired X axis) drive's this morning and it is working silky smooth!!! Even with 7000 motor speed in mach!After that i changed second axis line driver (Z axis) and is working perfect too!!!

I will check the encoder tommorow...
But i think is ok.(it is not the repaired one).Andi dont get any fault from the srvos software...
And the accel corrects this...

Strange to me is the higher acceleration seems to correct the problem.Before that i had acceleration of 200 only and i could not tune the motor (very unstable)...

If i try then to increase motor speed to let's say 1300 in Mach same thing happens...

 No up to 55% everything is smooth and normal.
After some more tuning it appears that i need to increase the acceleration a lot in Mach motor configuration.Someting like 3000 or even 5000 acceleration rate.That is with 1000 motor speed.That way jog works at 100% both ways.Is that normal?
