thank you for advice I will sure try this out! I think I messed about steps per mm (I don't use inches), i'm now at 3200 for this setting and when i say to machine to do +8 on Y it goes at 8cm, maybe the problem is here and I need to have a 32000 per unit instead 3200 to have millimeters. Will see what it changes.
Yes, I haven't received the 48v yet, not throwing money on new motors until I tried everything
Will invite aswell a friend of my who succesfully made a cnc but with leadshine drivers and stuff.
Will post the results!
Here I found a little calculator to mess around, gives me this :
